Digital Lith Processing

What kept me away from doing more digital photography was the lack of a program which would allow me to produce output with the look and feel of a darkroom lith print. It happened so often, that I photographed something with my digital camera and immediately thought: Sigh, I would like to do a lith print of it but my film camera is at home.

But in the last years more and more papers I used to do lith prints disappeared from the market and newer papers which showed up on the marked were not suited for the lith process. And so I got tired of hunting for old papers and stopped doing darkroom lith prints - there is nothing like a non-darkroom lith print.

So I went some time missing lith printing or at least something with the impression of a lith print. So I went on the net and looked for a digital fake process to produce something which at least looks a little bit like a scanned lith print. But all I could find was not very promising and lacking the look of the real thing. So I gave up on this and went back to grief-mode for some time.

The subconscious can be a strong driving force. So I started thinking about what makes a lith print look like a lith print and how I would be able to archive it by some program. The crux is infectious development and how grain is built up in this process. That made it clear that the key is an iterative process and that this will be something which will take time to compute. Very different from moving around a slider in some image manipulation program. Computation takes a long time - although not as long as the darkroom process, it will get some load on your computer. If you never heard the fan of your computer working, with this program it is very likely that it will happen.

The process itself is very flexible and I tried to parametrize it in a way that seems familiar for a darkroom lith printer.

And now it happens, that the program is already availabile in version 4. It went a long way to reach that point but all additions over time proved to be very valuable.

Version 4.11

• Now DigitalLith has a small dot file in user directory which specifies the session directory and also preferences file go there. This does no longer pollute the home directory with files of different digital lith versions.
• The border can now also be set in absolute pixels instead of a percentage.
• Now also a return in the development time input leads to an immediate development if that option is selected in the preferences.
• Fixed an error where development settings are not written to a jpg file.
• dlpcli now prints the usage message again.
• dlpcli now supports the border setting not in percentage
• In previous versions you could loose streaking settings if a streaking module was missing. That could happen if you move the extensions directory and in the next start Digital Lith could not find the extensions. This case is now handled by showing an unknown streaking and by preserving the settings so that they are there again once the module is in place.
• DigitalLith has now the standard streaking modules built-in. In case of a fix in the module, the module can get downloaded to override the built-in module.
• Lookup gradient is now also effective for lookup tables coming as png file.
• The Tutorial is finally updated and covers the current version.
• On first start of the program png is selected as default output format.
• The UI look&feel is now a bit more modern and allows for a dark or a light mode. A restart is needed to switch from one to the other mode.
• When showing the last developed image the blur setting is now applied correctly.
• A new standard process is included which is a bit cleaned up and which has the image evolving a bit more smoothly from the start. The old standard process is still there.
• There is now the possibility to not show image blur while running a test development but have it shown right after the development.
• The headers in the parameter panel now use a bigger font and the sections are indented for a cleaner view and easier usage.
• When expanding/collapsing parameter panel sections the development time no longer gets cleared out.
• Fixed an issue with showing last lithed image where after an image change in scale or border, or when switching between previews the last image could still be shown, although it is not valid.
• Fixed an issue where use of auto compile on parameter input did not respect the setting of fast development without UI update.
• Fix a bug where the change of the process module and then the selection of a streaking module changed the development time to 0.
• Multithreading has been slightly improved and should better support workload distribution on cpus with efficiency and performance cores.
• Better data locality in threaded processing almost doubles the computation speed.
• Better re-use of memory in batch processing leads to less garbage collection.
• DigitalLith now writes images data with sRGB color space
• Fixed some focus issues in image adjustments panel

Version 4.10.1

• Fix error in lookup gradient handling defaults. This got set to 0 instead of 1 for existing presets.

Version 4.10

• Show files in batch queue as tool tip of the number of files waiting.
• Show Prepare status in batch process while preparing the development. This immediately shows a message and shows the user that the batch process is running.
• New parameter gradient in color section to compress or stretch the LUT.

Version 4.9.1

• Now DigitalLith for MacOS is self-signed.

Version 4.9

• Now you can enable to do a test action without image update when on second preview with cmd-T instead of having to use shift-cmd-T.
• If you press the shift key when doing a preset selection a reset on the settings is done before applying the preset.
• DigitalLith now supports relative streaking where the strength of the streaking depends directly on the grain parameter of the process. There are four new streaking modules on the exchange which support relative streaking.
• For every section in the parameters panel there is now a separate reset icon which you can use to reset the parameters in this section to their default values. This is for example a quick way of removing all uneven development.
• With Java version 14 there is a packaging tool included again. DigitalLith is now built and bundled with Java 14 and no longer with Java 10.

Version 4.8.2.1

• Fixed a bug where the false parameter values of streaking modules got not displayed and the development did not happen because of that.

Version 4.8.2

• Wrong title in import preset dialog.
• Version check always reported new version avaliable

Version 4.8.1

• When the image that is to be processed is too big we run out of memory. In that case we do not show any error message.
• When doing a development without image update we now show the dev steps so that the user sees that a test development is running.
• The import preset dialog is now also working on Windows and Linux but you first select the file and then the category in a second dialog.

Version 4.8

• Ability to select the category when importing presets from file or exchange.
• Random button for selecting patterns and transformation in uneven development.
• Fixed bug where the preset description is not shown when updating a preset.
• Immediately show an empty image when a test development starts. Some streaking might take a long time and thus the user gets confirmation that processing started.
• As long as there is no pattern type selected the pattern related inputs are disabled.
• Possibility to embed preview image in lith result for faster operation when reading settings from lithed image file. For now this is only supported for images written in png format.
• Use the embedded thumbnail in original image in file chooser for faster file selection.
• Sometimes it is comfortable to see the effect of the parameters on a gray gradient. File->Use Gray Gradient shows a gray gradient that can be used instead of an image.
• Ability to right-click or ctrl-click on preset categotry to rename it.
• Allow image borders which are greater than 100%
• Possibility to apply an image blur after processing. The blur in the UI can be shown or not depending on the check mark in the adjustments settings. This is to speed up test development and then after development adjust the blur.
• New option to automatically use a unique file name if the file already exists.
• DLP CLI to run huge batches of images all through the same settings.
• When exporting a LUT from the color dialog, the coloring settings are stored in the PNG metadata so that they match once the LUT is selected and the user selects the color dialog.
• There is the possibility to test develop without continous image update to faster get to the result via cmd-shift-T/ctrl-shoft-T.
• You can define two different preview sizes which can be selected via cmd/ctrl-1 or cmd/ctrl-2. With a small preview image size this leads to nearly instant results.
• There is now a preferences setting which lets you decide if you want to automatically run a test development when pressing return in a process settings field. Depending on the current preview size a normal test run or a fast test run (when on preview size two) is done. After the run the contents of the text field are selected for faster change.
• Cleanup of the preferences dialog to use tabs for easier use.
• Support of transparency in png input files
• New Standard process to support transparency development

Version 4.7

• No longer use System FileDialog as it caused confusion when directory is changed and the image already exists.
• Fix a bug with window size/position from last session.
• Presets can be categorized and the categories in the presets panel can be expanded or collapsed. Old presets belong to the Default category.
• Preset categories can be set when defining the preset or when re-defining the preset or in the preset manager by selecting the preset and then with a right click to open the category selection popup.
• When adding a border to the image there is now the possibility to decided if the border size is computed from the long or the short edge of the image.
• Version 4.7 has reworked streaking modules and I also got rid of some of the older ones. E.g. There is no longer vertical and horizontal line streaking because that is better handled by the new line streaking. The older versions still work and where possible there is migration from the old modules to the new versions.

Version 4.6.5

• Time Travel now also can run into the future which allows for a step to step development.
• A finished test development can be continued with cmd-shift-S and is handled as a snatch development.
• Fixed bug in presets manager. When canceled has been selected, then all the Favorites got removed from the favorites menu.
• Going all the way back in development is cmd-down, going all the way forward is now cmd-up.

Version 4.6.4

• Time Travel feature which lets the user step through the last development steps by using cmd-left (back) and cmd-right (forward). Shift-cmd-left goes all way back and shift-cmd-right goes to the end of development. With cmd-point you can take over the current step into the development parameters. The feature can be switched off and the number of buffered steps can be configured in the preferences dialog. There is an option in the preferences panel to let you automatically take the time travel step into the development parameters without having to type cmd-point.
• Slowdown Shadow development parameter got renamed into Tray Movement. I high value of slowdown shadows correspondes to a low value of tray movement. Existing parameters get adjusted automatically. To have all your presets adjusted it is needed that they are stored once. You can force this to happen by creating a new preset.
• Fix a bug in reporting batch progress for disabled streaking modules. Disabled modules are no longer counted.
• When using a fast machine it is now possible to slow down the test development by lowering the test parallel level. The full development will still use the parallel level.
• Disable border tone and expose border when there is no border selected.
• The red line around the image when viewing the last development is now thicker.

Version 4.6.3

• If you test develop an image or image crop and change the parameters and then develop the same image or crop again with the new settings you can toggle between the current and the last development using command-L.
• A red border is shown around the image when the last development is shown.
• The sdk streaking base classes now support for a more coarse grain. The first streaking module using this is the 4.6.3 extra grain module which has a new parameter.
• Line 3 module had a bug which is fixed for the version 4.6.3 module.

Version 4.6.2

• SDK supports cross module migration of streaking modules.
• In the streaking popup you can not only switch to another streaking type of the same module, but also to a migrated type of another module. There are only modules listed which support migrating the current streaking type.
• Line streaking version 3 is the first streaking module which supports migrating from another streaking module. You can migrate from Line streaking version 2 which supported vertical and horizontal line streaking. Version 3 supports any angle and migrates horizontal to an angle of 0 and vertical to an angle of 90 degrees.
• New tool to generate lookup tables from simple definitions that you can take using a color picker. The tool allows to distribute picked colors over the gray tone range.
• Generated lut definitions from the lutgenerator can be used as lut instead of a full png lut. The extension is .lut

Version 4.6.1

• Java 9 has been a short term version. I moved on to Java 10 as the Windows launcher does not find a Java 9 download directory.
• Only provide self-contained versions of DigitalLith.

Version 4.6

• This version needs Java 9.
• New feature for advanced coloring via "Lookup tables".
• There is a new option in the image adjustments which allows the user to expose the image without exposing the image border. The option is only accessible if the selected process module supports this option.
• There is a new kind of process module in the SDK which allows to expose the image without the border. This is an extension to the existing process module interface and DigitalLith supports both kinds of process modules.
• The effect of uneven development can now be adjusted globally.
• There is a new kind of streaking module in the SDK which supports a global strength adjustment. All DigitalLith streaking modules you find on the exchange support a global strength adjustment.
• The manage favorites menu item is moved under the presets menu and now also allows to not only select which presets are favorites, but also which of the presets shall be removed. This is an easier way to cleanup your presets list instead of having to remove each preset one after another.
• The different parts of the parameter panel are now collapsible. This makes the parameter look cleaner.
• There is a new option in the preferences dialog to select the parts of the parameter panel run in solo mode. This means that if one part is expanded all the others collapse automatically.
• The options in the preferences dialog to show or hide the different parts of the parameter panel have been removed.
• In uneven development panel the streaking modules now can be collapsed or expanded via a triangle before the name instead of having to use the context menu.

Version 4.5.8.1

• Fixed an error when writing a 16 bit grayscale image into a jpg. Now there is an error shown in these cases.

Version 4.5.8

• New File-sub-menu to open the recently visited images including the last used settings in a (test)development of that image.
• Moved the deb package into Photography category instead Audio.

Version 4.5.7

• New File-sub-menu to open the recently visited images.
• New preferences entry to set the maximum recently visited images menu size. There is a hard maximum of 100.

Version 4.5.6.3

• Fixed wrong heap size in Linux package as well as the execute permission on the executable.

Version 4.5.6.2

• Increased max heap size to 8GB.

Version 4.5.6.1

• Fixed not using border lightness parameter when not apply pattern to image border has been selected.

Version 4.5.6

• There is a new option to add additional density to a pattern.
• Fixed error while computing autocontrast without border.

Version 4.5.5

• There is a new option in uneven development which lets you decide if the pattern shall also be applied to the image border. Previous versions always applied the pattern to the border.

Version 4.5.4

• Maximum heap size increased to 4GB for bigger images.
• Also deliver a version with smaller footprint which means the maximum heap size of 2GB of the previous versions.
• Streaking popup menu now lets you also enable/disable or collapse/open all streaking modules at once.
• Strength parameter for patterns can now be greater than one.
• When resetting a preset to current parameters you now can also rename it and select which parameters are part of the preset instead of just take the selection of the exiting preset.

Version 4.5.3

• fixed a bug with mouse handling in color dialog to work correctly with newer Java versions.

Version 4.5.2

• fixed another issue with uneven development patterns which made the pattern not applied to the image.

Version 4.5.1

• In some cases the crop got lost when elements of the image adjustments lost focus but without changing the adjustments.
• Black and White Only showed a black image in the ui.

Version 4.5

• The former Extended Standard Process is now the Standard Process. The extended process is no longer loaded and presets using it are migrated to the standard process when starting the program. You can also no longer download the process module from the exchange - why would you.
• When doing a test development with a cropped section you can toggle the view to be the cropped image only or have it scaled down and shown as in-image preview of the developed crop. The toggle can be done by Control-I (Windows and Linux) or Command-I (Mac OS).
• When in a test development, you can toggle the preview to show the original or the lithed image by pressing Control-J (Windows and Linux) or Command-J (Mac OS). To avoid confusion about the setting, showing the lithed image is switched on when starting a test development.
• SDK support for localized modules.
• Digital Lith now has a German localization again. You can choose the language to be either German, English or the operating system default (if it is set to German or English). All other locales default to English.
• Stop Batch button only enabled if there is a running batch process.
• When creating a preset with existing name, the unique name generated no longer uses the import preset prefix but a number appended to the name to make it unique.
• New reset button on preferences dialog.
• To keep the help up-to-date the help dialog now leads to the specific section on the documentation web page via your browser.
• When scaling an image you can now select to use a slower but better quality scaling.
• When adding an image border you can now select the border lightness with 100 being plain white and 0 being deep black.
• When selecting a preset which does not change the border or the scaling then Digital Lith keeps the selected crop instead of resetting it whenever a preset is selected.
• When selecting the setting from a processed file and the border and scaling is not changed digital lith keeps the current crop (if any).
• New preferences setting to ignore case when sorting the presets list.
• Support for Retina displays on Mac OS. Fonts are shown correct and there is a new preferences option to use the native retina display resolution in the image preview which allows for a finer and more accurate preview.
• Button bars at the bottom have different layout which now takes up less space and so allows for more flexibility when resizing.
• When using the system file dialog and have checked the unique name option in the Preferences dialog, now DigitalLith creates the unique name before opening the dialog so that if you do not change directory or filename the dialog shows the correct filename. If you then select an already existing name anyway then the existing file gets overwritten if you select so.

Version 4.4.3

• Had the wrong minimum Java version in the Windows launcher.
• Bug fix in initial pattern handling which resulted in a NullPointerException.

Version 4.4.2

• Fixed a bug in loading an image where a scale is only applied if there is a non zero border.
• When selecting a preset the crop got reset, but the preview not updated.

Version 4.4.1

• Filename without scaling but with border uses the image size plus border size in the filename.
• Save dialog does not have the filename set by default.

Version 4.4

• Use the system http proxy settings (if set) to connect to the exchange. This allows users sitting behind a firewall to access the digital lith exchange.
• Width of left and right panel is now adjustable.
• Window size and position as well as the width of the left and right panel is now restored from the last session.
• Extended Standard Process now supports a second application of grain to the paper after the application of uneven development settings. This required a change in the understanding of exposure steps in the process module. Please adjust your own development module accordingly. See the sdk documentation.
• There is a new preferences setting that lets the user choose the operating system file dialog instead of the Java one. The operating system file dialog saves the sorting column from one call to the next. One Note, at least on Mac OS the file dialogs locale can not be overwritten and so the buttons do not neccessarily appear in English (depending on your language setting - and Digital Lith is English only).
• Old version 3.x and before configuration files are no longer supported.
• To make a border size happen now also works when leaving the input field and not only when pressing return key.

Version 4.3.1

• New preference setting to automatically add size and border to filenames.
• Let the user specify a pattern to be added to file name for size and border, palceholders are SIZE and BORDER.
• New layout of preferences dialog to have it more compact in size.

Version 4.3

• No need to restart after download of modules.
• Reload of extension modules via menu (for development).
• New feature to scale an image before processing
• Image border and scaling now part of the preset (adjust image section).
• Presets can now be a combination of sections instead of one section or all.
• Some tool tips were not showing on start of the program. You had to go to the preferences dialog once to get them shown.

Version 4.2

• New gnome/debian install
• Share presets and session file on network drive by giving location in preferences. Preferences still stay in user home.
• Fix for default locations for session, presets and preferences files. They now default to the home directory.
• New feature to add an image border which is processed with the image. Image border settings are not part of the preset.

Version 4.1.3

• New coloring curve control to adjust all curve point relative to each other

Version 4.1.2

• Fixed a typo in add preset dialog.
• On Mac OS X when (test-) development or batch processing is finished and Digital Lith has no focus, the Digital Lith Icon in the dock jumps one time to get user attention.
• On Mac OS X you can go to full screen mode via Cmd-F. Press Cmd-F again to quit full screen mode.

Version 4.1.1

• Streaking module settings can be collapsed for better overview.
• New Preset type (Streaking only) which does not replace the streaking settings, but add the streaking parameters to existing parameters when selected.

Version 4.1

• Digital Lith now runs with higher precision. This required an updated sdk too. So if you develop modules (streaking or process) you need to update the sdk and adjust your sources as we now run on doubles and no longer on floats. Old modules error out on loading and are no longer supported. Please download new versions of the modules you need. And update your sdk if you are a module developer.
• New process modules may inherit from another module with respect to parameters. This allows to switch the process module and keep the parameters.
• There is now a new entry in the help menu to show the last errors logged into the log file.
• There is now a warning dialog if you try to overwrite an existing preset by adding a new one with the same name or by importing presets with the same name.
• Process and streaking modules contain now api to check if the given parameter values are valid and DLP will show a dialog to tell about these parameters when you run a (test-) development. Module authors do not have to implement this, but then must handle illegal values during runtime of the module. All modules coming with the DLP exchange implement the feature.
• When a preset got renamed it automatically got added to the favorites.
• The progress bar now shows the name of the file that is currently processed.
• In the color dialog you remove a curve point by crtl-clicking on it.
• The reset button in the color dialog now works correctly.
• When you click on the color gradient in the parameter panel on the left, a menu pops up and lets you select one of you color only presets. This allows fast access to the presets which deal with color only.
• The color of a test preview development is now not only adjusted on-the-fly when changing the color in the coloring dialog, but also if you select a coloring preset from the color gradient context menu or when selecting a preset from the presets or favorites list.

Version 4.0.5

• Streaking module settings can now be disabled. To disable/enable click on the name of the streaking type and select enable or disable in the popup menu.
• To cleanup the user interface, the buttons for each streaking settings have been removed. The corresponding functionality can be found in the popup menu opening when you click on the streaking type.

Version 4.0.4

• Fix for negative exposure in standard process. With negative exposure values less then -5 there were weird behavior and with exposure set to -5 the image kept white. This is fixed now and you can use negative exposure to increase image contrast. If you have already used negative values, then they are adjusted accordingly if they are not less or equal than -5.
• To open/load an image you can go via the File/Open menu or press command-O or press the Load button. To have this a bit more consistent the button is renamed to Open.
• There is a new button to clone a streaking module in the uneven development section. It is next to the remove button. If you click on the plus sign the same streaking will be appended to the end of the list of used streaking modules.

Version 4.0.3

• A bit more logging in error cases.
• Using system fonts when running on Mac OS X 10.11.x.
• Fixed a minor history glitch. When you selected a preset and then went back one step in the history you landed one step before that.

Version 4.0.2

• When using patterns, invert had no effect.

Version 4.0.1

• Allow users to use a comma as decimal separator in numbers.
• On Windows using a TAB to jump from one parameter to the next did not select the contents of the input field. This is now fixed.
• When clicking into a parameter input field the content is selected.
• There is a new preference parameter which lets you show parameter names with units. There is an sdk change for this (new interfaces which can be implemented). To use this in your own streaking/process modules you will have to download the new sdk.

Version 4.0

• When a test-development or development was snatched there was the wrong development time in the history entry.
• Digital Lith Exchange also serves streaking and process modules.
• New favorite preset menu feature lets you define a set of presets that you want to have faster access to, especially if the list of presets is long.
• New Coloring Mode which lets the user define the highlight, midtone and shadow curves.
• Select between old and new coloring mode.
• SDK for process modules.
• SDK changes - new V4 streaking module which allows for named parameters in the presets and session files.
• Possibility to build your own process modules.
• Presets, preferences and session are written to V40 versions so that your Verion 3 is still functioning.
• Exchange description no longer editable.
• Allow to change the streaking type within a streaking module in the streaking panel by clicking on the name of the streaking.

Version 3.5.0.4

• You had to install at least two streaking module to have them appear in the UI.

Version 3.5.0.3

• Made digital lith to be runnable with Java7 again so that you do not have to install Java8.

Version 3.5.0.2

• Locking of image file also when doing a normal development in case you have the programm running two times dealing with the same image.
• When starting the program and auto check for new version is switched on, Digital Lith needed a long time to be responsive if the network is down. Checking for new version is now done in the background.

Version 3.5.0.1

• When streaking modules were removed it could happen that the program no longer starts.

Version 3.5

• You can now apply more then one type of streaking.
• Instead of just the number of images in the batch queue, the program now also shows the progress of development of images in the background.
• Allow to switch off the section headers in the parameters area.
• Allow to only show parts of of the uneven development section of the parameters so that unused features do not take up too much space.
• When in cropped view and a new image is loaded, the cropSource was not cleared which resulted in test runs with wrong data for the streaking.
• There is no longer a process flavor. Instead you can give the radius of the area and are no longer restricted to the given sizes via the flavors. The radius is in pixels and the size we compute from is a 2*radius+1 x 2*radius+1 area. The old flavors for the weighted areas are compatible. If you give a radius of 0 this is the same as the old small area. Only the mid-size area flavor is not transferred into the new model. It gets also to a small area. This is the first time that the process is not backward compatible.
• Since there are more streaking modules to come and all will carry multiple streaking types, the UI now allows to trim down the list of types in use. If you only ever use one type of a module coming with many types, then there is no need that these other types fill up the drill down menu to select the type.
• Unused streaking module parameter fields are now hidden instead of just making them disabled.
• New streaking modules horizontal and vertical area.
• The sdk now hands in a log writer object so that a streaking module can log error or debug info.
• The sdk now also hands in the crop source for a cropped preview to simulate the look of a pattern which is not equally appied to all of the image.
• The sdk no longer hands in an Exposer object. That concept has not been functioning to well. Instead StreakingModuleBase provides helpers getMin and getMax to retrieve the minumum and maximum values of the negative which is better suited for the purpose of compensating in the paper only case.
• New format for session and presets files. Old files are still read.

Version 3.4.0.3

• Output images can now be in jpeg format also. Jpeg-Quality is defined in the preferences.
• With streaking defaults defined, when starting the program errors were written into the log where there were none.

Version 3.4.0.2

• New possibility to define your own defaults for streaking types.

Version 3.4.0.1

• When switching streaking types holding down the ALT key to preserve parameters and if the current type has fewer parameters than the selected type, then not all parameter input fields are enabled.

Version 3.4

• SDK change. Added new parameter exposer to doStreaking to better support paper only streaking types.
• List of streaking types is now sorted.
• Fixed an issue with loading streaking modules on Windows.
• Added a bit more logging.
• Log level is configurable in the preferences dialog.
• Existing streaking module have been adjusted to sdk changes. Make sure that when you use a paper only type in a preset to adjust the strength which is now more in the range of the normal types stength.
• New streaking modules horizontal/vertical line. These provide better control of the streaking than the existing line streaking module.
• Fixed an issue when starting with a non-existing session file. When quitting without a test or development run there was an error writing the session file.
• If you have done a test development or a non-batch development and the developed image is still seen in the UI, then the color dialog will show the changes immediately in the image too. This gives a better preview of the color changes compared to just the color gradient of the dialog.

Version 3.3

• Presets can have a description which is shown as tool tip when hovering over the preset name in the presets list on the right.
• If preset descriptions are shown or not can be configured in the preferences dialog.
• When storing presets, only the required information is written. There is no need to store development parameters for a color only preset.

Version 3.2.0.3

• Fix a bug when selecting the streaking module type.
• When a streaking type is selected, the values always will get populated with the types default values. If you want to keep the current streaking values, change the streaking type by pressing the ALT key. If you press the SHIFT key while changing the streaking type from one to another type of the same module, then the modules parameter adjust function will convert the existing parameters for the selected type (if supported by the module).
• The streaking module now allows for more than six streaking parameters. To keep the UI clean the streaking part of the parameters only shows the maximum number of streaking parameters that any installed streaking module needs.

Version 3.2.0.2

• Selecting another streaking type does not overwrite with defaults if selected with ALT key pressed.

Version 3.2.0.1

• When having automatic test run on preset selection and when selecting another preset during a test or development run started another test run. Both runs updated the preview image. A test run on preset selection will now only be started if there is no test/development run.

Version 3.2

• Changes in the SDK to support tool tips for streaking parameters as well as enabling/disabling the flip h/v button.
• Streaking modules are now fully modular. There is no longer a built-in streaking (except for no streaking). All streaking has to be provided by installing streaking modules. This allows the user to only have to select from the streaking modules needed instead of the full list.

Version 3.1.0.2

• Digital Lith did not start if the configured extensions directory does not exist. Now this just logs an error in the log file.

Version 3.1.0.1 (Codename J)

• Configurable color balance area size to allow color dialog to show on smaller monitors.

Version 3.1

• New coloring definition which give more control on how colors are blended.
• New streaking types added.
• No more streaking direction, but therefore parameters for horizontal and vertical which also allows to have the streaking in both direction.
• Streaking is modularized. You can build and use your own streaking modules by using the Digital Lith SDK.

Version 3.0

• Parameters take the whole left side of the window.
• The Presets list takes the whole right side of the window.
• No more cryptic entries in the parameters fields. Each parameter has its own input field.
• Only one process. Bromide increase process can be simulated with setting bromide increase to 3.
• Customizable bromide increase.
• Customizable sulfite increase.
• New streaking feature for uneven development.
• Customizable image preview window.
• Keep color and black and white only settings now are restored from last session.
• Ability to automatically run a test development once a preset is selected from the list.

Version 2.1

• Some of the dialogs were not centered to the main window.
• Floating point numbers are no longer shown in exponential representation. For example 0.0001 was shown as 1.0E-4.
• When in an development or test development you could click into the image to zoom in or out. This showed the original image (zoomed or not) for a short time until the develop process updated the image with the result of the next iteration. This is no longer happening as the click into the image during a development or test development does no longer change the zoom status.
• A new preferences option to automatically check for a new Digital Lith version on startup has been added. The check is switched off by default.

Version 2.0

• 2.0 total rework of everything, no changelog for previous versions

For those who are curious. There is now the possibility to implement and build your own streaking and process modules. If you know how to write Java code then it should be very easy for you to come up with your own modules.
