Use _wopen on a UTF8 -> wchar_t decoded filename to support UTF8 filenames
for win32.
|
|
Previously, we would only open files with the correct extension.
Until such time as we get file type detection by contents working
assume that any file that doesn't end in .xps or .cbz is a pdf
file.
|
|
Allows us to render files with broken font hinting programs when hinting
is enabled(whether by no-AA or DynaLab detection).
Fix bug 692949.

Use this to reintroduce "Document Properties..." in mupdf viewer.

Restricts rendering to a sub rectangle of the supplied bbox.

In my previous commit, I forgot to initialise the variable before
using it. Thanks to Bas Weelinck for spotting this.

Bas Weelinck points out a potential problem with multiple threads
starting up at the same time, running into a race condition in
the thread debugging code. He suggests using an extra lock to
avoid this, and indeed, it would be a simple way.
I am reluctant to introduce an extra lock purely for this case
though, so I've instead reused the ALLOC lock. This has the advantage
of us not having to take the lock except in the 'first call with a
new context' case.
|
|
When cloning, ensure the locks are done on the new context, not the
old one; this makes no difference except to suppress some spurious
debugging messages.
Also ensure that DEBUG is predefined for Makefile based debug and memento
builds.
Thanks to Bas Weelinck.

Don't reset the size of arrays until we have successfully resized them.
|
|
Depending on the operation used (< or <=) the threshold array should
never have either 0 and ff in it. As we are using <, it should never
have 0 in it. Fixed here.

The default page userspace transform changed to a top-down coordinate
space, and I forgot this detail when updating the text device branch.
Also remove the final block sorting pass to give preference to the original
PDF text order.

It seems that JPX images can be supplied in indexed format, with
both a palette internal to the jpx stream, and a palette in the
PDF. Googling seems to suggest that the internal palette should
be ignored in this case, and the external palette applied.
Fortunately, since OpenJPEG-1.5 there is a flag that can be used
to tell OpenJPEG not to decode palettes. We update the code here
to spot that there is an external palette, and to set this flag.

Currently all conversions from rect to bbox are done using a single
function, fz_round_rect. This causes problems, as sometimes we want
'round, allowing for slight calculation errors' and sometimes we
want 'round slavishly to ensure we have a bbox that covers the rect'.
We therefore split these 2 cases into 2 separate functions;
fz_round_rect is kept, meaning "round outwards allowing for slight
errors", and fz_bbox_covering_rect is added to mean "give us the
smallest bbox that is guaranteed to cover rect".
No regressions seen.

When coping with missing transparency entries, fill with 255,
not 0. Simplify code slightly so we fill completely, not just
to depth.
|
|
If entries are larger than they need to be, accept just the amount
we need. If not large enough, pad out with zeros.
|
|
Move fz_stroke_state from being a simple structure whose contents
are copied repeatedly to being a dynamically allocated reference
counted object so we can cope with large numbers of entries in
the dash array.

Thanks to SumatraPDF for the patch.

When we have finished replacing tiff->samples, free the old samples
block. Taken from Sumatra.patch - many thanks.

Bring up to date with current APIs, including text device changes.
|
|
Also tidy up the taking of fz_context *'s, and hide an unwanted indent
param.

Fix a couple of silly problems (one gccism, and one windows specific
bug).

Debug printing functions: debug -> print.
Accessors: get noun attribute -> noun attribute.
Find -> lookup when the returned value is not reference counted.
pixmap_with_rect -> pixmap_with_bbox.
We are reserving the word "find" to mean lookups that give ownership
of objects to the caller. Lookup is used in other places where the
ownership is not transferred, or simple values are returned.
The rename is done by the sed script in scripts/rename3.sed

In the existing code, glyphs are stored/retrieved from the glyphcache
with no reference to the antialias level used to create them. This
means that if we are using different aa levels in different threads,
we can retrieve 'non-matching' glyphs and hence get rendering
indeterminisms.
Fixed simply here by storing the aa level in the glyphcache too.

Details of buffers hidden in fitz-internal.h. Public API now just
lets us keep/drop and get storage details for a buffer.
fz_debug_outline{,_xml} lose the 'level' param in their public API.
fz_matrix_max_expansion hidden, as it's only used internally.
Document fz_setjmp/fz_longjmp and Apple specific hackery.

C's standard is copy(dst, src), so we move to adopt that here.
Hopefully no one is calling this routine other than us - if they are,
then I apologise! Better to aim for consistency before we freeze
the API at v1.0 than to carry an inconsistent API around ever after.

Instead of returning in 1.0 for underflow/overflow, return minimum
value for underflow and maximum value for overflow. NaN returns 1.0.
|
|
Floating point numbers are now clamped, division by zero is
approximated by minimum or maximum value and NaN results in 1.0.
|
|
Make fz_clone_context copy existing AA settings.
Add accessor function for fz_bitmap.
Add more documentation for various functions/types.
