Improves text processing and timestamp features.
Features
- Added new TimeStamp.DigestAlgorithm property: specifies the digest algorithm used to encode timestamp requests.
- If a PDF contains pages with errors, GcPdfDocument.GetText() now ignores those errors by default (previously, it would throw an exception). The new behavior is consistent with Adobe Acrobat Reader.
- Text processing (e.g. GcPdfDocument.GetText()) now process text rendered using invisible mode (text is neither filled nor stroked). Previously such text was ignored. The new behavior is consistent with Adobe Acrobat Reader.
