Changelog:

• Fixed lags of thumbnails view on resizing and scaling.
• An instant effect on applying thumbnail quality.
  It's possible to switch thumbnail quality while working on a project with the changes applied immediately. For each quality chosen a cache is created.
  Usage example: you could use this feature for the preview purpose, which is faster than simple navigating between pages. Undock the thumbnails panel, set the quality, for ex., to 700, and size to 1000. You can mark problem pages with Ctrl+Click on a thumbnail and navigate between these selected pages after finishing to fix them. To finish the preview change the quality and size values back and dock the panel.
• Added buttons to navigate between pages.
• Fixes for the auto and original alignment modes.
• Additional modifiers for auto adjusting content area.
  On double clicking inside the content box hold Shift pressed to select left or right edge only or Ctrl to select top or bottom one, or Shift+Ctrl to adjust both the nearest vertical and horizontal edges.
• Other fixes and improvements.

Note: x32 version supports Windows XP.

Changelog:

• Implemented the guides feature.
• Change the way of the adjustment of the despeckle strength.
  Now that's set via the slider. It allows to adjust the despeckle strength more smoothly and exactly. Value 1.0 matches the old cautious mode, 2.0 - normal and 3.0 - aggressive.
• Improve and return black on white detection feature.
• Added native color scheme and made various fixes and improvements on the Dark and Light schemes.
• Improvements on the thumbnails view:
  • Saving selection of pages on filter switch.
  • Separate highlighting for selection leader in thumbnails.
  • Navigating between selected pages. Use Shift+PgUp/Q and Shift+PgDown/W to navigate between selected pages.
  • More accurate multi-column list handling (Author: Alexander Trufanov).
  • Scaling thumbnails via Alt+Wheel (Author: Alexander Trufanov).
• Added options in the settings to manage the quality and size of thumbnails.
• Added order by completeness sort on the output stage.
  Moving incompleted pages to the end allows to process them in batch mode without processing the completed pages.
• Improved the lasso mode on zone creation.
  Also the hotkey is changed to Shift+Alt+LMB due to the old combination did not work on Linux.
• Added fill offcut option at the output stage.
• Now split layers are removed if the color mode was changed to any except mixed.

• Bug fixes.

Change log:

• Implemented the feature of auto adjusting content area.
• Deviation parameters added into the settings dialog. The deviation default settings have been calibrated.
• Improved: The follow page button is no more activated automatically on switching a sorting method or on going to the previous/next page.
• Auto and original alignment modes reworked.
• Added the ability to separately control vertical and horizontal automatic alignment when auto or original alignment mode enabled.

Change-log:

  • Posterization can now correctly handle with pale images.
    It's become possible due to normalizing the source image before posterizing.
  • Added normalize option so as to add the ability to get normalized output.
  • Force b&w option has been reworked.
• Improved: Follow page button is no more activated automatically on switching a filter if the button was inactivated before. Instead of that behavior ST now saves the sliders positions.
  Note: The old behavior caused some problems of loosing the position of the page sequence worked on if not natural sorting enabled.
• Collapsible filter options.
• Added "Higher search sensitivity" option into picture shape options.
  It gives the same search result as it was in Enhanced (& Featured) versions.
• Deviation feature reworked and added sorting by decreasing deviation.

Change-log:

• Fixed: ST used Otsu instead of Wolf and Sauvola binarization methods in some cases, ignoring the user settings.
• Fixed: ST could cut off edges of content in auto mode.
• Added "Off" picture shape mode.
• Fixed possible crash on switching from rectangular to another picture shape mode on some builds.
• Support for processing of images with light content on dark background.
• Fixed a lag on opening the settings dialog.
• Added project version compatibility check.
• Implemented page area feature.

Hotfix for version 1.0.7

Warning! Old project files aren't compatible with this version, you mustn't even try to open project files of version 1.0.7 or earlier with this version.

Change log:

• Fix for high DPI (ex. 4K) displays.
• Pages without content box will be blank at output. A content box deleted manually won't more be reset to the page bounds on reloading.
• On placing a new filling zone over another it now overlaps the older one.
• "Quadro" picture shape mode was merged with rectangular. Also removed the restriction of ver. Featured on deleting all the auto zones. Before it resulted in resetting all the auto zones back.
  Added sensitivity option. If sensitivity equals 25%, the results will be the same as they were in old "Quadro" mode, if 100% - as in old "Rectangular".
• Fixed bug come from ver. Featured: filling zones were set to wrong positions in their view after manual / marginal dewarping with post deskew enabled.
• Auto detection of the white on black option for Sauvola and Wolf binarization methods on the first time processing.
• Applied some fixes from ver. Universal.
• Other improvements and fixes.

Warning! Old project files aren't compatible with this version.

Changelog:

• Fixed bug from Enhanced: applying manual deskew settings to a multitude of pages didn't work for the pages with a size different from that of the page the setting is applied to.
  That resulted in resetting those pages to auto mode on processing. Also now deskew changes have effect on thumbnails instantly without forcing to reload the pages.
• Start batch processing dialog from Enhanced removed.
• Splitting output options are moved out of the color settings. Splitting options have its own "Apply To" dialog and button now.
• Fixed a bug of the official ST: ST could crash on output when outer margins and content rectangle are "touch" by its sides on margins stage.
• Fixed: on switching to manual alignment mode from any other the content rectangle was always placed at the top center instead of the place set by the align buttons.
• Fixed: Subtracting picture zones, placed over an auto layer picture zone, no more blink on zoom.
• Fixed: Picture zone type used wasn't sometimes saved on page switching.
• Added option to control highlighting (with red asterisks) the thumbnails of pages with high deviation. The option refreshes the thumbnails instantly.
• Fixed: page layout view didn't consider splitting settings. Corresponding improvements are done to thumbnails.
• Fixed: on applying a content box to other pages it could be set out of the page bounds.
• Fixed: possible mixed pixels in the output image of right page after splitting.
• Various fixes of thumbnails drawing.
• Changed Scan Tailor behavior on page split stage.
  1. Reworked apply cut feature. Now on applying cut to the pages with different dimensions than the page the cut applied to, Scan Tailor tries to adapt cutters instead of fully rejecting the cut setting and switching to auto mode for those pages as it was before. The later was annoying as pages could be similar and had the difference in a few pixels.
  2. Added check to reject invalid cut settings in manual mode.
  3. UI: Added cutters interaction between each other. They can't more intersect each other, which created a wrong page layout configuration before.
• Fixed bug from Enhanced: on select content stage after saving and reopening the project the thumbnail could change its position on the page loading when sorting enabled.
• Now outside pixels of color images are filled with the background dominant color not gray. The respective feature has been implemented.
  Also added filling setting with the following options:
  1. Background: estimate the background and fill outside pixels with its color.
  2. White: always fill with white.
• Tiff compression feature reworked.
  Now there are two options in settings dialog: B&W and color compression.
  • The B&W one has None, LZW, Deflate and CCITT G4 options.
  • The color one has None, LZW, Deflate and JPEG options.
• Other changes.

Warning! Project files of older versions of ST are not compatible with this version.

Changes:

• fixed: a page wasn't refreshed in output on changing its crop area;
• equalize illumination option does no more depend on white margins.

Changes:

• fixed bug from Enhanced: picture_shape in mixed mode wasn't saved in the project file that caused reloading page on every restart in output mode.
• fixed: filling color wasn't adapted on brightness change.
• improved output processing in B&W mode when illumination equalization disabled.

Changes:

• Images libraries reconfigured (the old configuration could cause some problems with some images).

Warning for a user of a 32-bit system: the count of threads for multi-threaded batch processing is limited to 2 threads due to memory constraints. And that is intended only for systems with 2GB RAM. If you have only 1GB RAM and lower, don't use this feature and set the count of threads to 1. Otherwise you are risking to get "out of memory" error.

Changes:

• Added option to disable post-deskew on dewarping.
  It should be applied to a cover with geometric distortions and without any text lines which the auto-deskew algorithm could rely on. Also it can be applied to pages with those that have non-horizontal text lines as part of the design and so the auto-deskew algorithm fails on that kind of pages.

  The setting is located at Output -> Dewarping -> Change... -> Post deskew

• Fixed: Post-deskew on dewarping enabled now fills the outside pixels with the dominant gray color in a color mode.

• Added option to control white on black mode for the adaptive binarization methods.
  It should be enabled when the text or content is lighter than the background.

Changes:

• bug fixes.

Initial public pre-release.
