Add isPDF methods to query availability of PDF specific methods.
|
|
The implementation does not need to be in the public API.
|
|
Otherwise we were tripping over the lack of the header file.

Move the definition of fz_font to be in a private header file
rather than in the public API. Add accessors for specific
parts of the structure and use them as appropriate.
The font flags, and the harfbuzz records remain public.
This means that only 3 files now need access to the font
implementation (font.c, pdf-font.c and pdf-type3.c). This
may be able to be improved further in future.

MSVC is obviously more picky than linux in some cases.

Commit c22e6a6dc2bf6acbac955bd5fbdd896329dfd725
accidentally removed the line endings for:
mutool show file.pdf grep

Divide up the work amongst the threads to solve the odd situation
of larger buffers producing slower runtimes.
Avoid creating (and hence clearing) larger bitmaps than required
at the end of the run.

Since -P only turns on BGPRINT (parsing and rendering in different
threads), the default bgprint.active needs to be false.
The filename and pagenum were only being printed for bgprint.active
mode, and the timing.total wasn't being updated for bgprint.active
mode. Also missing \n on bgprint.active showtime output.

Since the removal of the begin_page device function, structured
text extraction has been unable to correctly establish the
mediabox for extracted pages.
Update the fz_new_stext_page call to take this mediabox
information. This is an API change, but hopefully most people
are calling fz_new_stext_page_from_page or
fz_new_stext_page_from_display_list which are updated here to
cope.
Update all the apps/tools to behave properly.

These just convert fz_outline and fz_link into plain JS arrays and
objects with no associated native userdata.

Fix various niggles with muraster when compiled with no thread lib.
Thanks to Tamir Evan.

Closing a device or writer may throw exceptions, but much of the
foreign language bindings (JNI and JS) depend on drop to never throw
an exception (exceptions in finalizers are bad).

We want to turn pdf_page into a thin wrapper around a pdf_obj, so that
any updates to the underlying PDF objects will be reflected without
having to reload the pdf_page.

The mark & sweep pass of garbage collection, and resolving indirect objects when grafting objects
was following the full chain of indirect references. In the unusual case where a numbered object
is itself only an indirect reference to another object, this intermediate numbered object would
be missed both when marking for garbage collection, and when copying objects for grafting.
Add a function to resolve only one step for these two uses.
The following is an example of a file that would break during garbage collection if we
follow full indirect reference chains:
%PDF-1.3
1 0 obj
<</Type/Catalog /Foo[2 0 R 3 0 R]>>
endobj
2 0 obj
4 0 R
endobj
3 0 obj
5 0 R
endobj
4 0 obj
<</Length 1>>
stream
A
endstream
endobj
5 0 obj
<</Length 1>>
stream
B
endstream
endobj

The generation number is only needed for decryption, and is assumed
to be zero or irrelevant for all other uses.
Store the original object number and generation in the xref slot, so
that we can decrypt them even when the objects have been renumbered,
without needing to pass the original object number around through
the stream loading APIs.

Affects pdfclean, pdfmerge, and pdfposter.

We had moved the ctm into the display device, which meant it
no longer transformed the bounds given to the list device to
do scissoring. Move it back.
Same fix for muraster.

In an earlier commit, I changed some of the band writing functions
to take the band starting offset, rather than the band number. This
was done to accomodate the idea of rendering the page in bands of
different heights.
Sadly, it seems I didn't push this all the way through, and had
different band writing functions still taking the band number.
Fix all the band writing functions to be consistent.

Regardless of whether rendering in background thread or not the
filename and the page number should be printed.

A cutdown mudraw that only copes with simple raster output.

To return the proper size from fz_bound_display_list, which has been
broken since the begin_page device call was removed.
|

Allows us to remove the out parameter 'transform' from fz_begin_page.
