MuPDF Changelog

What's new in MuPDF 1.24.0 RC 1

• Error handling changes:
• You must call pdf_report_error in the final fz_catch. Any unreported errors will be automatically reported when a new error is raised, or when closing the fitz context.
• New formats:
• Read Office (XML) files! We internally open and convert docx/pptx/xlsx documents to HTML to allow reading the plain text content. The exact layout will NOT be preserved.
• Optional compile time option to use libarchive for reading CBR and other archive formats.
• Read plain text documents.
• Read gzipped files directly.
• Open and read FDF files to support importing annotations or form data using the low-level PDF functions. There are no tools for this yet.
• Read CFB (Compound File Binary) format archives -- used for the Office formats.
• Write images as JPEG2000.
• New tools and features:
• mutool bake (and associated functions) to bake appearance of annotations and forms into static content.
• Font subsetting flag to mutool clean (EXPERIMENTAL FEATURE).
• Option to use ObjStms when writing PDF files.
• Compression effort option when writing PDF files.
• Add option to control how line art is affected by redaction. Add more options to control how images are affected by redaction (remove-unless-invisible).
• Fix up q/Q gstate balance when cleaning content streams.
• New functions and types:
• pdf_rearrange_pages to subset or re-order pages in a PDF file.
• fz_invert_bitmap to invert monochrome bitmaps.
• fz_compressed_image_type to query the format of a compressed image.
• fz_text_decoder to convert various legacy and CJK encodings into UTF-8.
• More helper functions to easily manipulate PDF objects in C.
• Add flag to control fz_place_story overflow behavior when the text doesn't fit into the box.
• New archive handlers can be added at runtime.
• Major bug fixes and improvements:
• Support using Art, Bleed, Media, and Trim boxes for PDF page size.
• Support ActualText in PDF! No more strange text extraction when the file uses ActualText to patch over bad font encodings.
• Add special TrueType fallback encoding CMap for a specific flavor of broken PDF files that use an "identity" encoding without embedding the font.
• Limited "transfer function" suppError handling changes:

• Add special TrueType fallback encoding CMap for a specific flavor of broken PDF files that use an "identity" encoding without embedding the font.
• Limited "transfer function" support in PDF. Transfer functions are a deprecated legacy PDF feature that predates proper color management. They were intended to provide limited color management such as applying a gamma curve. Transfer functions have often been (ab)-used to invert images, and many PDF creators use them when writing softmask images. We have added support for this case only.
• Box drawing characters added to fonts for HTML and plain text documents.
• Write more compact PDF files (removed some unnecessary whitespace).
• Improved selection behavior for non-axis aligned text.
• Improved heuristics for detecting the logical and visual order of RTL text in PDF.
• Improved heuristics for inserting missing spaces in PDF text.
• Improved handling of CMYK JPEG files (which ones are inverted and which are not).
• Improved content type detection. Don't assume everything is PDF when we can't recognize it.
• Removed deprecated functions:
• pdf_check_signature
