Call fz_append_string instead of fz_append_printf for static strings.
Call fz_write_string instead of fz_write_printf for static strings.
|
|
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.

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.

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).

This silences the many warnings we get when building for x64
in windows.
This does not address any of the warnings we get in thirdparty
libraries - in particular harfbuzz. These look (at a quick
glance) harmless though.

Split compressed images (images based on a compressed buffer)
and pixmap images (images based on a pixmap) out into separate
subclasses.

The DP and BDC operators, are used in the form:
<NAME> <PROPERTIES> <OPERATOR>
where <PROPERTIES> can either be a name (that can be looked
up to get a dictionary) or an inline dictionary.
What the spec doesn't say is that the two are not
interchangeable. If you resolve the name to an inline
dict, then insert it, Acrobat will give an error for
some (but not all) cases.
The interpreter currently resolves any references, and
passes the resolved version into the operator handling
function. This precludes us outputting the original
form.
We therefore update it to pass both the raw and the cooked
versions in. This has no effect on MuPDFs own handling of
anything, it just enables the buffer device to output
a correct stream.

Use fz_output in debug printing functions.
Use fz_output in pdfshow.
Use fz_output in fz_trace_device instead of stdout.
Use fz_output in pdf-write.c.
Rename fz_new_output_to_filename to fz_new_output_with_path.
Add seek and tell to fz_output.
Remove unused functions like fz_fprintf.
Fix typo in pdf_print_obj.

Update buffer and filter processors.
Filter both colors and stroke states.
Move OCG hiding logic into interpreter.

Purge several embedded contexts:
Remove embedded context in fz_output.
Remove embedded context in fz_stream.
Remove embedded context in fz_device.
Remove fz_rebind_stream (since it is no longer necessary).
Remove embedded context in svg_device.
Remove embedded context in XML parser.
Add ctx argument to fz_document functions.
Remove embedded context in fz_document.
Remove embedded context in pdf_document.
Remove embedded context in pdf_obj.
Make fz_page independent of fz_document in the interface.
We shouldn't need to pass the document to all functions handling a page.
If a page is tied to the source document, it's redundant; otherwise it's
just pointless.
Fix reference counting oddity in fz_new_image_from_pixmap.

Rename fz_close to fz_drop_stream.
Rename fz_close_archive to fz_drop_archive.
Rename fz_close_output to fz_drop_output.
Rename fz_free_* to fz_drop_*.
Rename pdf_free_* to pdf_drop_*.
Rename xps_free_* to xps_drop_*.

Previously pdf_process buffer did not understand inline images.
In order to make this work without needlessly duplicating complex code
from within pdf-op-run, the parsing of inline images has been moved to
happen in pdf-interpret.c. When the op_table entry for BI is called
it now expects the inline image to be in csi->img and the dictionary
object to be in csi->obj.
To make this work, we have had to improve the handling of inline images
in general. While non-inline images have been loaded and held in
memory in their compressed form and only decoded when required, until
now we have always loaded and decoded inline images immediately. This
has been due to the difficulty in knowing how many bytes of data to
read from the stream - we know the length of the stream once
uncompressed, but relating this to the compressed length is hard.
To cure this we introduce a new type of filter stream, a 'leecher'.
We insert a leecher stream before we build the filters required to
decode the image. We then read and discard the appropriate number
of uncompressed bytes from the filters. This pulls the compressed
data through the leecher stream, which stores it in an fz_buffer.
Thus images are now always held in their compressed forms in memory.
The pdf-op-run implementation is now trivial. The only real complexity
in the pdf-op-buffer implementation is the need to ensure that the
/Filter entry in the dictionary object matches the exact point at
which we backstopped the decompression.

Pass in the 'tight' flag.
|
|
Using this, we can reconstruct pdf streams out of the process
called. This will enable us to do filtering when used in
combination with future commits.
