V25.6 での更新項目

機能

• The ability to get and set alternative text for images has been added for the XImage class. New GetAlternativeText and TrySetAlternativeText methods allow you to get and set the alternative text corresponding to an image.
• Information about the Aspose.PDF license is now accessible from code, eliminating the need for third-party apps to explore the license file.
• Interruption of operations is now working when processing large HTML-fragments. Use the InterruptMonitor class in the same way as previously to control other operations.
• SetTextStyle method family has been added to the FreeTextAnnotation class. They enable you to set formatting for individual text fragments (or the entire text) in an annotation.
• The usual use case for SignatureCustomAppearance is to create text over a signature image. However, in some cases, Users prefer to do the opposite: position the signature image in the foreground and the text in the background. This is now possible thanks to the new IsForegroundImage setting.
• The property LinkDuplicateStreamsScanLevel was initially conceived to strike a balance between speed and quality when optimizing a document, aiming to reduce the load in complex search cases. Now that the search for duplicate objects has been significantly optimized, this option is no longer needed and has been removed.
• Reduced page optimization time.
• You can now tag PDF documents for alternate text of logos and images.
• Improved table processing performance for 10000 rows.
• Decreased memory usage during the processing of a large volume of text data.
• Optimized the Operator Collection indexing logic to enhance generator performance.
