The new version Diff GT 3.1 is available for download. The latest release of the PDF comparison software for circuit diagrams and technical drawings includes the following changes:

  • NEW: View in the main window can be changed by a new toolbar button A|⌀|B. By default, the button is set to ⌀ and an overlay of version A and version B is displayed in the main window. Alternatively, the new toolbar button can also be used to switch the view between version A or version B.
  • NEW: Exclusion areas take into account the paper format
    • When creating exclusion areas, the paper format of the corresponding page is automatically saved.
    • If a page range of several pages is then selected via the context menu (right-click) Valid for… (e.g. 1- for all pages), the exclusion area will only take effect on other pages that have the same paper format.
    • Similarly, in batch mode when using the argument --areas=excl.xml, the paper sizes of the exclusion areas stored in the XML are also automatically taken into account.
    • The menu item Copy to similar pages has been removed.
  • NEW: Under Settings > PDF > Textextraction Flags a new flag add unicode CMAPs has been added (turned off by default). In some cases, the flag can be used to repair defective text extraction in PDF files if illegible characters are extracted due to fonts with incorrect encodings.
  • NEW: Tooltips for text differences show special characters in Unicode representation U+xxxx
  • NEW (Add-On Batch): New arguments for the command line call --ox=report.xml and --saveas=project.diffgt
  • Fix (Add-On Batch): Settings loaded with --settings did not take effect
  • Fix (Windows version): Memory size (stack) increased for processing of extremely large PDF files
