206
207
208 New formats:
209
210 Read Office (XML) files! We internally open and convert
211 docx/pptx/xlsx documents to HTML to allow reading the plain

215 and other archive formats.
216
217 Read plain text documents.
218
219 Read gzipped files directly.
220
221 Open and read FDF files to support importing annotations or
222 form data using the low-level PDF functions. There are no tools
223 for this yet.
224
225 Read CFB (Compound File Binary) format archives -- used for the
226 Office formats.
227
228 Write images as JPEG2000.
229
230 New tools and features:
231
232 mutool bake (and associated functions) to bake appearance of
233 annotations and forms into static content.

267
268 Support using Art, Bleed, Media, and Trim boxes for PDF page
269 size.
270
271 Support ActualText in PDF! No more strange text extraction when
272 the file uses ActualText to patch over bad font encodings.
273
274 Add special TrueType fallback encoding CMap for a specific
275 flavor of broken PDF files that use an "identity" encoding
276 without embedding the font.
277
278 Limited "transfer function" support in PDF. Transfer functions
279 are a deprecated legacy PDF feature that predates proper color
280 management. They were intended to provide limited color
281 management such as applying a gamma curve. Transfer functions
282 have often been (ab)-used to invert images, and many PDF
283 creators use them when writing softmask images. We have added
284 support for this case only.
285
286 Box drawing characters added to fonts for HTML and plain text
287 documents.
288
289 Write more compact PDF files (removed some unneccessary

295 of RTL text in PDF.

299 Improved handling of CMYK JPEG files (which ones are inverted
300 and which are not).

302 Improved content type detection. Don't assume everything is PDF
303 when we can't recognize it.

611
612 Various cleanups:
613 Per-function documentation comments moved to the source file.
614 Hopefully they will stay up to date more often than when they
615 were hidden away in the header file.
616
617 Removed unused internal testing tools: mjsgen and jstest.
618
619 Removed TGA output support. Use one of the more common and useful PAM,
620 PNM, PNG, or TIFF formats instead.
621
622 Removed support for PDF portfolios. This work-in-progress feature was
623 never completed, and only worked for a small subset of files.
624
625 Removed support for progressive loading. This rarely used feature added
626 a lot of complexity and was an unending source of bugs and strange
627 behaviour. Removing this feature has allowed us to clean up and
628 simplify large amounts of code, and fix dozens of bugs in one fell
629 swoop.
