The scissor argument is an optional (potentially NULL) rectangle
that can give hints to devices about the area that can be scissored.
This is used by the draw device and display list device to minimize
the size of temporary clip mask buffers.
The scissor rectangle, if used, must have been transformed by the
current transform matrix.

|
The Forms object should have been dropped once the reference was
created for it. Also needed to clean up the group and font
objects that the device maintains.

|
When cleaning a file, we discard any Annot entries that no longer
point to genuine pages. Or at least, we should have done, were it
not for the fact that we only handled the /A form of Annots, and
not the /Dest form of annots. Fixed here.

When printing a PDF object to a file, if it was a name, then we'd
output without a required \n. For example:
10 0 obj
/SomeNameOrOtherendobj
This would trip gs up.

Extraneous explicit type casts can mask errors, especially if a
function prototype or return value changes in the future.

Image objects are immutable and opaque once constructed.
Therefore there is no need for the const keyword.
|
|
Shading objects are immutable and opaque once constructed.
Therefore there is no need for the const keyword.

Match naming of fz_moveto/lineto etc for paths.
|
|
We compile with -Wno-unused-parameters instead.
|

|
|
Use the flags when selecting a fallback font.
|
|
Also fix a memory leak.
|
|
Spot (broken) values that will require special 'acrobat
compatible' handling and use the old code for that.
|
|
Look up fallback fonts by unicode script, with a flag to select the serif or
sans-serif font style where such variants exist.
Move all builtin fonts into fitz namespace.
|
|
It's an opaque immutable structure, that we don't expect to ever want
to change after creation. Therefore the const keyword is not useful,
and is only line noise.
|
|
The font is an immutable opaque structure, no need to add the const
keyword since users aren't expected or expecting to change it.

"0.00-70" should be parsed as one token, not two tokens as we did.

In general, we should use 'const fz_blah' in device calls whenever
the callee should not alter the fz_blah.
Push this through. This shows up various places where we fz_keep
and fz_drop these const things.
I've updated the fz_keep and fz_drops with appropriate casts
to remove the consts. We may need to do the union dance to avoid
the consts for some compilers, but will only do that if required.
I think this is nicer overall, even allowing for the const<->no const
problems.

Keeps operations in the int domain as long as possible,
and only resorts to floats if required.

js_pcall was leaving crap on the stack in case of errors.
AFSimple_Calculate needs access to the doc object, but cannot use the
usual 'this' binding since it's a function. Add a global reference to
the doc object MuPDF_Doc.

In preparation of adding pdf_write_document that writes a document
to a fz_output stream.
|
|
|
|
Separate naming of functions that save complete files to disk
from functions that write data to streams.
|
|
We can now group all clipped text into one fz_text object and simplify
the device interface.
|
|
|
|
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.

See Bug 696284. Do not set disallow_new_increments in pdf_create_document, as
this breaks following calls to pdf_sign_signature.
See also the comments in bug 696251.

arrays
The list box and combo box can have values that are 2-element arrays. The first element
is the "export" value and the second element is the value that should be shown
in the list box UI. This fix ensures that we get the proper value to show in the UI.
Also, it adds the option to get the export values. These are needed if you wish to
update the field dictionary's V (value) entry, which is the currently selected values(s).
This fix works well with gsview. The other viewers will now display the proper content
in their UI, (unlike before this fix) but may need a bit more work to ensure that the
proper V (value) is updated with changes in the selections. In addition, we add
selection rectangles to the selected list box items.

When writing incremental xref streams, the opts->use_list entry of the last
object, i.e. of the xref stream object itself, was left uninitialized. This
resulted in a random value, 0 or 1, being written into the xref stream.
Also, always write a newline before the endstream keyword, as that shall be
done for xref streams and should be done for all other streams.
|
|
In pdf_create_document set disallow_new_increments to 1. Without this, the
calls to pdf_new_ref in pdf_create_document create an incremental xref
section. The following call to pdf_set_populating_xref_trailer then does not
set the trailer of the final xref section.
