V26.3 での更新項目

機能

• Lossless image stream recompression during PDF optimization. The OptimizationOptions.CompressAllContentStreams property now also compresses image XObject streams with the lossless FlateDecode filter when no other filter has already been applied to an image.
• Image compression encoding during PDF optimization. With this change, image recompression is now aligned with the selected encoding during optimization, making the results more predictable when resizing images, limiting resolution, and tuning quality settings.
• Render comments when saving as image or HTML. This feature makes it possible to preserve comment visibility in exported output formats instead of limiting them to PDF viewers only.
• Improved PDF to TIFF rendering performance.
