DocumentUltimate v7.7.0

Version 7.7.0 - August 26, 2025

• Improved: Updated PDF.js library to 5.4.54 for stability and performance.

• Fixed: Avoid The `container` must be absolutely positioned. error in revisited Viewer pages on iOS Safari.

• Improved: Scrollbar colors are beautified and made consistent for all themes.

• Fixed: Setting a specific theme like "classic-light" or "classic-dark" was no longer overriding user OS preference.

• Improved: Stability and performance of Portable formats.

• Improved: For text watermarks, if the text has any CJK characters (Chinese, Japanese, Korean) and no font is specified
  then by default use a CJK font instead of Helvetica font, so that the text watermark is displayed correctly, out of the box.

• Improved: When using DocumentViewerMatchOptions.MatchAnyWord, now the quotation marks can be used to specify phrases
  inside a query that is set via DocumentViewerSearchOptions.Term.
  For example;

  • red "four wheels" petrol will match red or four wheels or petrol or red four wheels petrol
  • red ""four wheels"" petrol will match red or "four wheels" or petrol or red "four wheels" petrol

  documentViewer.SearchOptions.Term = "red \"four wheels\" petrol";
  documentViewer.SearchOptions.MatchOptions = MatchOptions.MatchAnyWord;
  
  //If you have an array of phrases, you can surround them with quotation marks 
  //and then join them with spaces to form a query:
  var phrases = new[] { "red", "four wheels", "petrol" };
  var query = string.Join(" ", phrases.Select(p => $"\"{p}\""));
  documentViewer.SearchOptions.Term = query;
  documentViewer.SearchOptions.MatchOptions = MatchOptions.MatchAnyWord;

  Note that two consecutive quotation marks "" can be used to escape, i.e. to search for a quotation mark literally as ".
  The same feature can also be used in the Viewer's Find dialog.
