linkOther Changes

Roughly categorized, not an exhaustive list.

linkRobustness:

  • [pdf] Improved error handling when processing JPEG 2000 files.
  • [pdf] Handle separation names that are not valid Unicode.
  • [pdf] Better recover from errors in initial document loading when JavaScript is enabled.
  • [pdf] Fixed a problem where particular JBig2 files could not be completely read.
  • [pdf] Better handle corrupt documents consisting of two PDFs stitched together.
  • [pdf] More robust handling of temp files and directories with unexpected permissions.
  • [xod] Now limit the number of pattern usages before flattening will occur. This is needed to avoid frequently used simple patterns from making very complicated output files.
  • [pdf] Updated ElementWriter to better support editing of any existing PDF file when used in conjunction with ElementReader. (ElementWriter.SetDefaultGState and updated ElementWriter.Begin).

linkImprovements:

  • [pdf] Updated XFDF import to support importing Form Fields, Links and File Attachments.
  • [pdf] Output the “All” separation when in separation export mode.
  • [xod] Added elements to XOD files to support faux bold (stroked and filled text).
  • [pdf] Added better handling for zero-area filled paths.
  • [pdf] Improved redaction annotation rendering to support custom attributes used in Acrobat.
  • [pdf] Support encrypting files with no user password using AES 256.
  • [pdf] Adjusted RefreshAppearance for Radio Buttons to produce output similar to other PDF viewers.
  • [xod] Adjusted logic so if flattening is not disabled that pages with Knockout or Isolated Transparency groups are flattened.
  • [pdf] Updated logic so that the level passed to PDFNet.SetDefaultFlateCompressionLevel() will be respected even for image compression. (where the maximum compression setting would generally be used).
  • [pdf] Added support for soft masks in PNG and TIFF image export.
  • [pdf] Added a dropdown indicator for combo boxes.
  • [pdf] Now automatically support arbitrary rotations of rubberstamp annotations.

linkOptimizations:

  • [pdf] More efficient handling of empty transparency groups.
  • [pdf] Improved performance of SetDoc in PDFview by asynchronously reading page info.
  • [pdf] Lowered memory usage when incrementally saving to stream.
  • [pdf] Optimized reading from a file that has been edited.
  • [pdf] Optimized parsing of PDF documents with large amounts of whitespace.

linkBugfixes:

  • [pdf] Fixed a bug where IsModified can return true after a save when undo redo is used.
  • [pdf] Fixed bug where we would fail to save to documents with malformed “Rights enable” dictionaries.
  • [pdf] Fixed a bug where we would sometimes mishandle softmasks smaller than their containing group.
  • [pdf] Fixed bug where disabling annotation rendering in the viewer would not disable it in thumbnails.
  • [pdf] Fix bug in .Net wrapper where exceptions thrown in the PDFDoc constructor could crash.

linkOffice:

  • [xlsx] Added support for "sparkline" charts in xlsx files.
  • [xlsx] Added support for the NPER (number of periods) financial function.
  • [docx] Now correctly display change-tracked content.

  • [xlsx] Added support for inline strings within table cells.
  • [xlsx] Improved behaviour when text within a cell exceeds the horizontal cell bounds.
  • [docx] Improved positioning of some forms of rotated images.
  • [xlsx] Improved positioning of some forms of rotated images.
  • [pptx] Slightly improved handling of text effects.
  • [xlsx] Improved positioning category axis legends.
  • [docx/pptx] More robust handling of symbol encoded text runs.
