23.2.0

New in this Release

  • KeyView format detection has been extended, with support for 56 additional file formats.

  • KeyView can now extract all platform-specific embedded files from PDF_Fmt documents.

  • KeyView can now process certain OpenOffice Text files that it would previously reject, and it can process image alt text in OpenOffice Text as hidden text.

  • KeyView could truncate long sections of text in PDF_Fmt documents.

To avoid this, ViewingSDK now places images at the start of paragraphs to ensure that the text is readable, making the output more consistent with HTML Export.

  • KeyView could skip some user defined properties in summary information for some OLE-based files like MS_Project_2007_Fmt.

  • When using the pdfsr reader for text in right-to-left languages, diacritic characters were sometimes not extracted correctly.

  • Some PDF files took longer to process in version 12.13.0 of the SDK than in version 12.12.0.
