Add API to:
* allow enumeration of layer configs (OCCDs) within PDF files.
* allow selection of layer configs.
* allow enumeration of the "UI" (or "Human readable") form of layer
configs.
* allow selection/toggling of entries in the UI.

In particular ensure that curl builds properly for 32 and 64bit
modes.

This will only be built in "DebugCommercial" "ReleaseCommercial" and
"MementoCommercial" configuration builds.
A note on the way MSVS solutions work; libluratech is listed as
a dependency of the executables - this applies to ALL configurations.
In order to stop normal builds failing when we have no source, we
set each non "Commercial" configuration to not build libluratech.
The linker still looks for the output from the libluratech stage
to link in though, so for all non "Commercial" configurations, we
have the libluratech stage set to produce output named " ". This
is copied into the linker command line, and all is happy.
The sole downside to this is that if we try to build libluratech
in "Debug" (say) rather than "DebugCommercial", the build will
fail at the library making step. This will never happen unless
we manually try to build that project in that configuration though.

The implementation does not need to be in the public API.
|

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.

These build the mupdf desktop java viewer.
|
|
generated.sh was broken (wrong font path).
load_pnm.c had been omitted from VS projects.
|
|
Allows testing of SUPPORT_GPROOF builds on windows.

Presumably because the files were hand edited before, and
MSVC likes to alphasort.

Use this for plotters so we can see which ones are being used
in any given build.
Build with -DTRACK_USAGE to enable.
|
|
Add some paranoid checks to pdf_graft_object to prevent user
errors from crashing mupdf.
|
|
Some new files hadn't been added to the solution, and we were
calling strcasecmp instead of fz_strcasecmp.

svg: Implement graphics state stack.
svg: Use idmap for symbol and use elements.
svg: Put viewport and viewBox in state stack.
svg: Rebase to version 1.9 master.

This commit adds a page merging tool. The tool demonstrates the
use of object grafting. The object grafting function recursively
goes through the object to add all referenced objects. A map is
maintained to ensure that objects that have already been copied are
not copied again.

Update generate.bat to generate generate/fontname.c files rather
than generate/fontname.{ttc,ttf,cff} etc.
Add a new libfonts target that builds those, and make libmupdf
depend on it.
Fix build problem in load-bmp.c - don't declare in the middle of
blocks.

Simple PS wrapped images with flate compression.
|
|
To avoid having to duplicate a fairly large block of code several
times, use repeated inclusion of a header with some macros to
generate optimised glyph plotters.

Initial framework for creating pdfs
This adds a create option to mutool for us to use in working
on the API for creating content as well as adding content to
existing documents.
mutool create: Get page sizes and add them
Start the parsing of the contents.txt file which may have
multiple page information. Add the pages at the proper sizes.
Further work on mutool create_pdf
Remove the calls that were being made to the pdf-write device.
Clean up several issues with the reading of the page contents.
Get the content streams for each page associated with the page->contents
Temp. created a pdf_create_page_contents procedure. I will merge
this with pdf_create_page as there is significant overlap.
Next is to add in the font and image resources and indirect references.
Include pdfcreate in build
Merge pdf_create_page_contents and pdf_create_page
Add support for images in pdfcreate
This adds images to the pdf document using a function stolen from pdf-device (send_image).
This was renamed pdf_add_image_res and added to pdf-image. Down the road, send-image will
be removed. Prior to that, I need to work on making sure that multiple copies of the same
image do not end up in the document.
Code was also added to create the page resources to point to the proper image in the document.
Next fonts will be added in a similar manner, then I will work on computing the md5 sums of
image and fonts to ensure only one copy ends up in the document. Then pdf-write will be
reworked to use the same code as opposed to its current list of md5 sums that are stored in
a device structure.
mutool pdfcreate: support for WinAnsiEncoded fonts
Added support for very simple fonts (WinAnsiEncoding). Methods
added in pdf-font.c. Added first_width and last_width to fz_font_s
and stem_v to pdf_font_desc_s.
Ran code through memento with simple test of 4 page document
creation including an image and a font. Fixed several leaks
as well as buffer corruption issues (main changes in pdfcreate).
Thanks to Robin for the help with Memento in finding leaks.
Added StemV to pdf names as it was needed for the font descriptor creation.
Fix for pdf_write_document rename to pdf_save_document
Add resource_ids to pdf document structure
The purpose of this structure will be to allow the search
and reuse of resources when we attempt to add new ones
to the document.
Fix name changes from recent updates
pdf_create branch updated to work with recent changes in master
Initial use of hash table for resources
To avoid adding in the same resource this adds a
resource_tables member to pdf_document. The
resource_tables structure consists of multiple
fz_hash_table entries, one for each resource type.
When an attempt is made to search for an existing
resource, the table will be initialized in a brute
force search for existing resources. Currently this
is only set up for the image resources and accessed
through pdf_add_image_res. If a match is found,
the reference object is returned. If no match is found
NULL is returned and the ref object created in pdf_add_image_res
is added into the hash table. In this case, a command line
such as
create -o output.pdf -f F0:font.ttf -i Im0:image.jpg -i Im1:image1.jpg \\
-i Im2:image.jpg contents.txt
will avoid the insertion of two copies of image.jpg into the
output PDF document.
CID Identity-H Font added for handing ttf
This adds a method for adding a ttf to a PDF as a
CID font with Identity-H mapping and a ToUnicode
entry that is created using FT_Get_Char_Index
This takes much care in the creation of the ToUnicode
CMap to ensure that the minimum number of entries
are created in that we try to use beginbfrange as
much as possible before using beginbfchar. The
code makes sure to limit the number of entries in
a group to 100 and to not cross first-byte boundaries
for the CID values as described in the Adobe
Technical note 5411.
Add missing file pdf-resources.c
pdf-resources.c was missing and should have been
committed earlier. Added to windows project file.
Not sure where else it needs to be added for the
other platforms.
Clean up names and spacing
Make sure that the visible functions have the proper namespace (e.g. pdf_xxxx)
Also make sure we have a blank line prior to comment.
Be consistent with static function naming in pdf_resources.c
pdfwrite make use of image resource fz_hash_table
The pdfwrite device now shares the structure that stores the
resource images for pdfcreate. With this fix, pdfwrite now
avoids duplicating the writing of the same images that are
shared across multiple pages.
Add missing file pdf-resources.c
Initial work toward having pdfwrite use Identity-H Type0 encoding for fonts
Finish of CID type0 Identity-H font for pdfwrite
This adds in the proper widths which may have been stored in the source font
in the width table (parsed from the W entry in the pdf file) or if the
free type structure has its own cmap then we can get the width from free type.
Widths are restructured into format described in 5.6.3 of PDF spec.
Fix issue from conflict merging and multiple define of structure
Clean up warnings and make mutool create use simple font

Take on a (slightly tweaked) version of Simon Reinhardt's
patch.
The actual logic is left entirely unchanged; minor changes
have been made to the names of functions/types to avoid
clashing in the cmapdump.c repeated inclusion.
Currently this should really only affect xps files, as strtof
is only used as fz_atof, and that's (effectively) all xps for
now.
I will look at updating lex_number to call this in future.

Because of a shortcoming in harfbuzz, we can't easily force
all its allocations through our allocators.
We fudge it, with the addition of some macros to change
malloc/free/calloc into hb_malloc/hb_free/hb_calloc. To
prevent thread safety issues, we use our freetype lock
around calls to harfbuzz.
We stash the current context in a static var.

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.

In preparation of adding pdf_write_document that writes a document
to a fz_output stream.
|
|
Don't rely on having to run the page once with an identity transform
before being able to load the links.
|
|
Disable the use of link time code creation. I don't believe this
costs us much (if anything) and it avoids VS2005 dying on
release builds due to a bug triggered by the use of 64bit
fz_off_t.
|

|

Also fix a few ifdefs in time.c so that it builds on MinGW.
|

Neatness doesn't override actually working.
This reverts commit efb5a38ca0bac3537ceaf3383681a518df133143.

Easier than duplicating getopt for wchar_t, since we already
have windows specific functions to convert wchar_t strings.

Windows build was broken with commit 642a59a4de683a1359733229943be285e3e45c4f

Given a document, generate a gproof file from it. This encapsulates
the name of the file, the desired resolution for proofing, and the
page dimensions of all the pages in the file.
The idea is that an app will call this when it is asked to go into
'proofing' mode, and will reinvoke itself on this file. This gives
the gprf document handler just enough information to fake up a
document of n pages of the required sizes. Each page will then be
autogenerated on demand.

Doesn't actually trigger generation from ghostscript, or load
images from files generated by ghostscript yet.
|
|
Simple set of functions for managing sets of separations. Separations
have names, equivalent rgb/cmyk colors, and can be enabled/disabled.
|
|
This will be required for the gprf work.

Previously, only the unix executable had been updated to take
command line flags; update the windows one in line with it.
We have to cope with the argv being in Unicode; add a windows
specific version of getoptw for this.
Also note that that fprintf's in the windows mupdf exe won't work
as GUI apps don't have a console window, and can't write to the
parent one. Fixing that is a larger project than I have time
for right now.

People worrying about the minimal extra memory this takes can
disable it if required.
