2026.7.2 中的更新

特性

• Added support for extracting and accessing PDF Optional Content Groups (OCG/layers), including layer hierarchy, visibility, and object-level layer metadata.
• Added ChromePdfRenderOptions.CssPageRulePolicy and header/footer overlap detection options to improve margin handling and prevent content overlap when rendering or modifying PDFs.
• Enhanced PDF scanning reliability by removing shellcode hash-based detection rules that could cause inconsistent false-positive results.
• Enhanced render timeout handling by detecting stalled PDF generation operations and returning clearer, more actionable error messages.
• Updated internal dependencies.

修補程式

• Fixed engine stability issues that could cause orphaned browser processes, unexpected crashes, and rendering failures under heavy load or constrained CPU environments.
• Fixed an issue where PDF redaction could leave partial-character artifacts or remove excess content due to inaccurate text bounding boxes.
• Fixed an issue where ImageToPdfConverter.ImageToPdf could generate blank PDFs for image filenames containing both spaces and multiple dots.
• Fixed an issue where multi-page TIFF conversion did not preserve per-page orientation and resolution for mixed-orientation PDFs.
• Fixed an issue where Cleaner.SanitizeWithSvg could add an extra page and corrupt non-ASCII text in sanitized PDFs.
• Fixed an issue where PDF signature timestamps could display an incorrect timezone offset during daylight saving time (DST).
