Also save history when glut closes the window or otherwise exits the
main loop.

This release includes the auto-generated ragel files, so we don't need
to use the Artifex branch anymore.

Use MuJS to parse/write JSON object.

Such as the Windows XP "C:\Documents and Settings\" user directories.

When clicking a text/choice/signature field, pop up a dialog to fill in

Drop the unused 'serif' argument to the CJK lookup functions.
Use the BCP 47 names for CJK scripts and languages:
zh-Hant for traditional Chinese,
zh-Hans for simplified Chinese,
ja for Japanese,
ko for Korean.
The lookup function also allows commonly used language+country codes:
zh-TW and zh-HK for traditional Chinese,
zh-CN for simplified Chinese.

Don't bother compiling the freetype C files that are #included by ftbase.c
This fixes a harmless "repeated symbol" warning in the windows build.

Using #ifdef FZ_ENABLE_ means we build code in, even if we have
defined FZ_ENABLE_WHATEVER to be 0 (as we do in config.h).

MuPDF may attempt to load a page but fail to do so, e.g. due to
a circular page tree. When this happens the page will never be
introduced into the document's list of pages. Its next and prev
pointers are both NULL, but the code in fz_drop_page() falsely
assumed that the prev pointer was always set.
Thanks to oss-fuzz for reporting.

Keep a list of currently open pages for each document. Attempting to
load a page that is already loaded will return the same instance again.

There is a regression for 2325_-_JPX_image_with_padding_rejected.pdf.
Object 3 in that document is a JPX-encoded image. Its EOC marker is
preceded by two extra bytes of data, 0x80 0x80. This makes the file
broken according to the JPEG 2000 specification.
Acrobat Reader and the Kakadu JPX decoder accepts this file without
issues, so OpenJPEG 2.1.0 added code to fix this (bug 226, commit
005e75bdc). That fix detects exactly two bytes of 0x80 0x80, a rather
brittle fix. Adding more padding or changing the padding byte values
is not accepted. Adding more padding is acceptable to Acrobat Reader
and Kakadu. An unrelated fix for another problem has since broken
OpenJPEG's support for this broken image.

This removes the need for unistd.h, which isn't around on
VS2005.
Also remove unused variable.

The upsampling code in the JPX decode attempted to guess a
suitable upsampling factor. The guessed factor was wrong,
causing writes of samples outside of the decoded image buffer.
Simply limiting the coordinates to the image buffer would
not suffice because the factor was wrong for every upsampled
row of pixels. openjpeg does provide an upsampling factor,
so use that instead and also take the component offsets into
account when decoding components into the pixmap. Combined
this resolves the issue that previously triggered ASAN.
Thanks to oss-fuzz for reporting.

pdf_page_transform() may throw due to a cycle in the page tree.
When this happened mupdf would previously forget to drop the
default colorspaces obtained, after this commit they are dropped.

This requires subclasses of Device to implement its full interface.
It also makes the compiler complain if there is a difference between
the interface in Device and its subclasses. The drawback is that
all Devices are required to implement all methods, but that is an
easy hurdle to overcome. This change found the discrepancies between
the Device, NativeDevice and TraceDevice interfaces fixed in the
previous commits.
|
|
Several previous updates to the Device interface required updates
to TraceDevice but were forgotten.

Not popping causes assert to be triggered in fz_draw_end_group().
|
|
Abstract methods in interfaces offer no implementation and are
implicitly declared public, making a public access modifier
redundant.
