Version 11.2.0 Changelog (January 8th, 2025)

Version 11.2 is primarily a bugfix release.

• [pdf] Optimized rendering and display performance of large pages containing a lot of tiling patterns.
• [pdfua] Improved ordering of annotations during auto-tagging.
• [pdf] Improved support for badly formed PDFs where an indirect Length object was used inside an XRef stream. Previously this could cause most of the page content to come out as blank.
• [pdf] Improved handling of corrupt PDFs with negative object numbers. Previously this could cause PDFDoc.InsertPages to throw an exception when copying a page from one PDFDoc to another.
• [html] Improved HTML to PDF error reporting when the margins exceeded the paper size or were otherwise inconsistent. Previously the conversion could fail with the vague exception of "An internal error happened between the SDK and the HTML2PDF module", which was replaced by more descriptive error messages.

• [pdf] Fixed a potential memory corruption issue in ElementWriter.WriteGStateChanges() that previously could sometimes lead to a crash.
• [pdf] Fixed an issue that could cause a stack overflow when iterating over deeply nested page trees.
• [pdfa] Fixed a crash with a specific set of files when converting to PDF-A levels 1, 2 or 3 conformance A.
• [pdf] Fixed an issue with redacting non-painting path operators. Previously non-redacted content on such pages could get incorrectly scaled, rotated and/or skewed.
• [pdf] Fixed an issue where reading a corrupt JPEG image was resulting in the process hanging indefinitely.
• [pdf] Fixed a memory leak that could occur when using Font methods to create a new CIDTrueTypeFont multiple times from the same path or memory buffer.

• [pdfa] Fixed an issue with conversion to PDF/A-1b of a file that uses a CMYK color space. The document was missing a CMYK OutputIntent resulting in failure to validate with third party PDF/A validation tools.
• [pdf] Fixed an issue where TimestampingConfiguration.TestConfiguration() failed to verify a timestamp with CMS that contains both SigningCertificate and SigningCertificateV2 attributes.
• [pdf] Fixed a redaction issue where the overlay text did not appear vertically aligned to the top due to an unusually small font size.
• [pdfa] Fixed PDF/A-1, 2 and 3 validations of documents where form fields that are parents of widgets have actions of their own in addition to the widget.
• [pdf] Fixed an issue where ImportPages could cause some form field widgets to have the incorrect field value in the output document. Previously manually selecting a form field in some PDF viewers could cause its value to change unexpectedly.
• [pdf] Fixed an issue with FreeText annotation appearance generation where the vertical position of text within the generated appearance could be slightly different from what is displayed in WebViewer and other PDF viewers.
• [pdf] Fixed an issue where after XFDF import, more than one widget in a group of mutually exclusive checkboxes could be checked at the same time, due to the fields inappropriately sharing the same name.
• [pdf] Added file type verification to the Data Extraction Module's conversion methods. Previously conversions of files without a .pdf extension could fail with inconsistent error messages.
