• Bugfix: breaks generated by the merging algorithm for a table-row containing empty cells had always a penalty of 900. Committed by VH. See Issue 43766.
• In case of missing cells the border-end of the table was applied to an inner cell, instead of the (empty) cell in the last column. Committed by VH.

  • Initial modifications to the related LMs: initialized with the font corresponding to the first of the triplets.
  Committed by AD.
• PropertyCache phase 2:
  • improvement of the PropertyCache itself should now guarantee acceptable performance of the static caches in multi-session environments, which is a possible problem with synchronizedMap.
  • changed CommonFont to use the cache: added CachedCommonFont to contain the properties that are always cacheable CommonFont itself is only cached if the remaining properties are absolutes.
  • changed CommonHyphenation, KeepProperty, ColorProperty and FontFamilyProperty to use the cache.
  Committed by AD.

Changes to Renderers (Output Formats)

• Added an option to disable the default sRGB profile in PDF output for those who don't care about color fidelity, but care about PDF file size. Committed by JM.

Committed by JM.
• Fixed generation of named destinations so it works when the PDF document is encrypted. Committed by JM.
• Bugfix: allow multiple bookmarks to point at the same destination. Committed by JM. See Issue 37993.

• The default sRGB color profile provided by the Java class library is no longer embedded if it is encountered. This should reduce the PDF size considerably. Committed by JM.
• Changed the internal representation of colors to use Java's own color infrastructure instead of FOP's home-grown classes. Committed by JM. Thanks to Max Berger. See Issue 38946.
• Content in block-containers makes better use of shrink to fit content vertically into the available area. This can be used indirectly to justify content vertically in a block-container. Committed by JM.

• Bugfix for invalid handling of ICC color profiles in JPEG images and for dealing with CMYK JPEG images with the Adobe APPE marker. Committed by JM.
• Bugfix: Certain filter combinations in PDF could lead to invalid PDFs. DecodeParams were not properly handled. Committed by JM.
• Bugfix: CCITT Group 4 encoded TIFF images with multiple strips are now properly embedded in PDF files. Committed by JM.
• Bugfix: Fixed a copy/paste error in the table layout code that caused wrong page break decisions when table-headers and/or table-footers are used. Committed by JM.
• Bugfix: Fixed an NPE that was thrown when a table was used inside a footnote-body. Committed by JM.
• Bugfix: Fixed a problem with certain TrueType fonts which are missing the "PCLT" table, where a baseline-shift="sub" had no effect due to a missing x-height value. (Note: This only affects TTFReader, so the font metric file has to be regenerated.) Committed by JM.
• Bugfix: When the base URL was specified as a file system path, the constructed URL was wrong. Committed by JM.
• Bugfix: Fixed two causes for ClassCastExceptions in BlockContainerLayoutManager. Committed by JM.
• Bugfix: padding-top and padding-bottom on list-items could lead to wrong page break decisions and thus to overlapping text. Committed by JM.
• Bugfix: break-before and break-after were ignored on list-items. Committed by JM.
• Bugfix: The elements representing a non-breaking space weren't always correct. Committed by LF. See Issue 38507.
• Bugfix: Text-decoration was not promoted if no text-decoration attribute was specified on a nested element. Committed by JM. See Issue 38453.
• Bugfix: Spanned cells could lead to an false error message about overlapping cells and ultimately a NullPointerException. Committed by JM. See Issue 38397.
• Bugfix: Regions with non-standard names got ignored in RTF output leading to missing headers and footers. Committed by JM.
• The RTF output now properly generates the "\landscape" flag for documents in landscape orientation. Committed by JM.
• Following a clarification by the XSL FO SG, space traits are only set on the first and last area generated by an FO, and not on every area anymore. Committed by JM.
• Bugfix: Floating point numbers were not properly formatted in the PDF renderer which could lead to error messages while opening a PDF in Acrobat Reader. Committed by JM.
• Bugfix: Spans that end up with a negative height don't get swallowed anymore. Committed by JM. See Issue 38054.
• Bugfix: Certain border styles could lead to a NullPointerException. Committed by JM. See Issue 38132.
• Bugfix: Space was not adjusted if the space was on a nested block. This could lead to content overflowing the bottom of a page. Committed by JM. See Issue 38102.
• Bugfix: TableCell did not properly report that it generates reference-areas which could lead to wrong inherited values for start-indent and end-indent. Committed by JM.
• Bugfix: Image height for BMP images was incorrectly calculated Committed by MM. See Issue 38089.
• Bugfix: NullPointerException on certain fo:inline within lists. Committed by MM. See Issue 38053.
• Bugfix: ClassCastException on certain fo:inline with border combinations. Committed by MM. See Issue 37743.
• Changed a method name in LineArea from finalize to finalise because it was never intended for the method to be an override of the Java Object finalize method. If invoked by the Java garbage collector it may cause a NPE. Committed by MM.
• Implement property name as default argument on some xsl-function calls. Committed by SP. Thanks to Gerhard Oettl. See Issue 38098.
• Implement force-page-count property of page-sequence. Committed by SP. Thanks to Gerhard Oettl. See Issue 38087.
• Improvements to the code for inline block content. Committed by SP.
• Revision of refinement white-space handling. Committed by AD.

Changes to the Code Base

• Added checks that warn about tables and block-containers that are wider than the available content area. Committed by JM.
• First attempt at SVG support in RTF output. SVG images are converted to 300dpi JPEG images internally. Committed by JM.
• The command-line now automatically sets two parameters for any XSLT transformation: "fop-output-format" contains the MIME type of the currently selected output format, "fop-version" contains FOP's version number. Committed by JM.
• Added an alternative set of rules for calculating text indents which tries to mimic the behaviour of many commercial FO implementations that chose to break the rules in the FO specification in order to better meet the natural expectations of inexperienced FO users. Committed by JM.
• font-family list still not fully supported but a comma-separated list is now properly tokenized. FOP will now go through all fonts in the list to find one that is available, but it doesn't do so per character, yet. Committed by JM.
• Implemented "Overconstrained Geometry" rules (5.3.4, XSL 1.0) for the most important cases. Committed by JM.
• Support for leader painting in PostScript output. Committed by JM.
• Support for hyphenation-ladder-count. Committed by LF, MM.
• Fixed a bug where the linefeed-treatment property value "preserve" was not honoured when used in conjunction with text-align="center". Committed by MM.
• Bugfix: hard breaks with even-page or odd-page were not handled correctly when spaces were surrounding the break. Committed by JM. See Issue 37964.
• Fixed a bug where SVG content could be clipped when rendered to PostScript. Committed by JM.
• Changed the way resolutions are handled. The single resolution in the user agent got split up into source and target resolutions. For more info, see the updated documentation. Note: backwards-incompatible change! Committed by JM.
• Bugfix: Some content inside a table-header may not have been renderered on pages n > 1 in certain conditions. Committed by JM. See Issue 37875.
• Fixed a bug where an empty line, i.e. a block containing only a  , was not rendered at all. Committed by MM.
• Fixed a bug where the area for a finished cell that is broken over pages was created once for each row it was spanned over instead of only once. Committed by JM.
• Bugfix: Footnotes were lost if the footnote appeared in centered text. Committed by JM. See Issue 37880.
• Fix to correct image sizes in RTF output. Committed by JM.
• The output file is now deleted when an exception occurs when calling FOP from the command-line. Committed by JM.
• Bugfix: Areas for table-cells that are broken over more than one page are now generated even if all its content is already painted on a previous page. This fixes strange effects like a table grid that is not completely painted. Committed by JM.
• Bugfix: Column balancing produced strange break decisions in certain multi-column documents with large amounts of text. Committed by JM. See Issue 37828.
• Bugfix: The combination of content-width="scale-to-fit" and content-height="100%" did not work as expected due to a datatype conversion bug. Committed by JM. Thanks to Tom Craddock. See Issue 37815.
• Bugfix: A span="all" on the first block cause a subsequent page break and the first block didn't span all columns. Committed by JM. See Issue 37813.
• Bugfix: Self-created OutputStreams in PNG Renderer were not properly closed. Committed by JM.
• Bugfix: Relatively positioned BlockViewports (from block-containers) caused the paint cursor not be be properly advanced when space-before or space-after were present. Committed by JM.
• Bugfix: Space resolution was incomplete for content in table-cells. Conditional elements didn't get removed. Committed by JM.
• The validation check for non-zero borders and padding on a region-* and for empty static-content elements is now turned off when relaxed validation is active to improve compatibility with FO documents written for other FO implementations. Committed by JM.
• Bugfix for "/ by zero" ArithmeticExceptions when an URL to a non-existing image is used and content-width and/or content-height is used. Committed by JM.
• Bugfix for a multi-threading problem: propertyListTable initialization moved from the constructor to a static block in FONode. This fixes NullPointerExceptions in PropertyList. Committed by JM.
• Bugfix for placement of text inside a text area when borders are present in PostScript output. Committed by JM.
• Deprecated Fop constructors that use integer constants to select the output format have been removed in favor or the constructors that use MIME types. Committed by JM.
• Changed the XMLHandler interface so it doesn't report the MIME type it supports but instead can report whether it supports a particular Renderer implementation. XMLHandlers are now configurable. Committed by JM.
• Improved log and error messages in a number of places by adding additional context information that should make it easier to find the location in the source files. Committed by JM.
• Additional checks to detect text overflows. The overflow property is now properly handled where applicable. Committed by JM.
• Source location information improved. If location information is not available, the context information is provided based on text content. Committed by JM.
• The border-collapse property on fo:table is now forced to the value "separate" until the collapsing border has been implemented. Committed by JM.
• Improvements on leader painting in PDF output. Committed by JM.
