Update MSVC projects for thirdparty libraries as submodules.
Improve thirdparty library availability checks in Makethird by
checking for the existence of a README file instead of just the directory,
since a checkout without active git submodules has empty directories
for the third party libraries.

The default is to embed the full font.

Make libmupdf-v8 depend on libmupdf. This dependency isn't true, but
it stops both things trying to call fontdump at the same time during
the build, which causes build failures.

Include paths for thirdparty stuff were wrong.

No idea how it seemingly worked without these changes.

Previously, we've been working with a prebuild v8 lib, only available
in a single (debug) configuration.
Here, we move to reading the include files from
thirdparty/v8-3.9/include and getting the built libs from
thirdparty/v8-3.9/build/{Debug,Release}/lib/ as appropriate.
|
|
We only seem to have a debug build of the v8 build to work with at
the moment though...

Simple command line tool made from cutting all the windows specifics
out of win_main.c and adding a simple script handler in.
Read lines from the script, and feed those events to pdfapp. Screenshot
pages as required.

The calc.pdf specific version of pdf_jsimp is no longer needed and hence
dropped.
|
|
This also provides a way to test whether interactive methods
are supported.
|
|
Make a separate constructor function that does not link in the
interpreter, so we can save space in the mubusy binary by not
including the font and cmap resources.

Divides large format pdfs into a new pdf with multiple pages, that tile
the original PDF.

Expose pdf_write function through the document interface.

This shuts up the spurious 'overflow' warnings when outputting
pages.

I'd missed changing the openjpeg include paths to 1.5 somehow.
Fixed here.
CLUSTER_UNTESTED as we don't use the solution.

Just makefile/solution changes.

Attempt to separate public API from internal functions.

Forgot to move this earlier.

Introduce a new 'fz_image' type; this type contains rudimentary
information about images (such as native, size, colorspace etc)
and a function to call to get a pixmap of that image (with a
size hint).
Instead of passing pixmaps through the device interface (and
holding pixmaps in the display list) we now pass images instead.
The rendering routines therefore call fz_image_to_pixmap to get
pixmaps to render, and fz_pixmap_drop those afterwards.
The file format handling routines therefore need to produce
images rather than pixmaps; xps and cbz currently just wrap
pixmaps as images. PDF is more involved.
The stream handling routines in PDF have been altered so that
they can recognise when the last stream entry in a filter
dictionary is an image decoding filter. Rather than applying
this filter, they read and store the parameters into a
pdf_image_params structure, and stop decoding at that point.
This allows us to read the compressed data for an image into
memory as a block. We can then restart the image decode process
later.
pdf_images therefore consist of the compressed image data for
images. When a pixmap is requested for such an image, the code
checks to see if we have one (of an appropriate size), and if
not, decodes it.
The size hint is used to determine whether it is possible to
subsample the image; currently this is only supported for
JPEGs, but we could add generic subsampling code later.
In order to handle caching the produced images, various changes
have been made to the store and the underlying hash table.
Previously the store was indexed purely by fz_obj keys; we don't
have an fz_obj key any more, so have extended the store by adding
a concept of a key 'type'. A key type is a pointer to a set of
functions that keep/drop/compare and make a hashable key from
a key pointer.
We make a pdf_store.c file that contains functions to offer the
existing fz_obj based functions, and add a new 'type' for keys
(based on the fz_image handle, and the subsample factor) in the
pdf_image.c file.
While working on this, a problem became apparent in the existing
store codel; fz_obj objects had no protection on their reference
counts, hence an interpreter thread could try to alter a ref count
at the same time as a malloc caused an eviction from the store.
This has been solved by using the alloc lock as protection. This in
turn requires some tweaks to the code to make sure we don't try
and keep/drop fz_obj's from the store code while the alloc lock is
held.
A side effect of this work is that when a hash table is created, we
inform it what lock should be used to protect its innards (if any).
If the alloc lock is used, the insert method knows to drop/retake it
to allow it to safely expand the hash table. Callers to the hash
functions have the responsibility of taking/dropping the appropriate
lock, and ensuring that they cope with the possibility that insert
might drop the alloc lock, causing race conditions.

No other code changes.

All in one command line replacement for muxpsdraw and mupdfdraw.
|
|
File references escaped deletion in previous commit.
|
|
Rather than having a custom build step that generates the font
and cmap "generated" files, have it as a separate project.
This enables us to nuke the generated directory as part of the
clean step, and to list the files in the solution explorer.

This a) improves our branding, and b) avoids conflicts with
other pdf tools out there (pdfinfo etc).
|
|
Updated thirdparty.zip contains newer jpeg, jbig2 and freetype code.
|
|
Add simple combined exe build for mupdf/muxps tools.

Move to a non-pdf specific type for links. PDF specific parsing is
done in pdf_annots.c as before, but the essential type (and handling
functions for that type) are in a new file fitz/base_link.c.
The new type is more expressive than before; specifically all the
possible PDF modes are expressable in it. Hopefully this should
allow XPS links to be represented too.
|
|
Firstly, we rename pdf_store to fz_store, reflecting the fact that
there are no pdf specific dependencies on it.
Next, we rework it so that all the objects that can be stored in
the store start with an fz_storable structure. This consists of
a reference count, and a function used to free the object when
the reference count reaches zero.
All the keep/drop functions are then reimplemented by calling
fz_keep_sharable/fz_drop_sharable. The 'drop' functions as supplied
by the callers are thus now 'free' functions, only called if
the reference count drops to 0.
The store changes to keep all the items in the store in the linked
list (which becomes a doubly linked one). We still make use of
the hashtable to index into this list quickly, but we now have
the objects in an LRU ordering within the list.
Every object is put into the store, with a size record; this is
an estimate of how much memory would be freed by freeing that
object.
The store is moved into the context and given a maximum size;
when new things are inserted into the store, care is taken to
ensure that we do not expand beyond this size. We evict any
stored items (that are not in use) starting from the least
recently used.
Finding an object in the store now takes a reference to it already.
LOCK and UNLOCK comments are used to indicate where locks need to
be taken and released to ensure thread safety.

draw_simple_scale.c is a cut down version of draw_scale.c, that only
uses filter functions that return values strictly in the 0 to 1 range.
Because of that, we can use bytes rather than ints as intermediate
storage, and have no clipping to do.
