Passing a pdf_document to pdf_graft_object to specify the source
document is redundant, as if we need to know the document, it will
be pickled into the object we are copying.
Similarly, repeatedly having to pass the destination document
seems silly when we can just pickle it into the map too (and this
removes the possibility of people using a different destination
document part way through).
This leaves to simplifying the pdf_graft_object call, at the expense
of splitting it into 2 calls - one with a map, and one without.
Also, we can delay the creation of the mapping table until we are
first asked to copy an object that requires deep copying. This
avoids us ever having to manually pass in the source document.
This has knock-on effects in the java and javascript classes, but
with the advantage of being clearer in the end (IMHO).

If DISABLE_MUTHREADS is set, don't include the thread helper library.
If FZ_ENABLE_PDF is 0, don't include mupdf/pdf.h.

This makes is possible for JNI code to depend on the
library for error handling.

In keeping with the rest of the code.

It seems odd for a document writer to pass a device pointer
out, and then require it to be passed back in.
Hide that in the public API.
|
|
Rename fz_write to fz_write_data.
Rename fz_write_buffer_* and fz_buffer_printf to fz_append_*.
Be consistent in naming:
fz_write_* calls write to fz_output.
fz_append_* calls append to fz_buffer.
Update documentation.

Not number of coordinates.

Valgrind doesn't know realloc(p, 0) is equivalent to free(p), so
unfortunately we can't reduce all calls to just realloc().

Previously, attempting to put an object beyond the end of
an array would throw an error. Here we update the code to
allow objects to be placed *exactly* at the end (i.e. to
extend the length by 1).
Update js use of pdf_array_put.
|
|
|
|
Also expose the argument to JS and JNI.

Move the definition of the structure contents into new fitz-imp.h
file. Make all code outside of fitz access the buffer through the
defined API.
Add a convenience API for people that want to get buffers as
null terminated C strings.

All link destinations should be URIs, and a document specific function
can be called to resolve them to actual page numbers.
Outlines have cached page numbers as well as string URIs.

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.

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

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).

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

endstream
endobj
5 0 obj
<</Length 1>>
