Werner Lemberg 7ef266045f [sfnt] Reduce footprint if WOFF and WOFF2 support is not needed. 
Based on a patch from metarutaiga (MR !106).  The gist of this commit is
that it doesn't make sense to support WOFF without compression (which would
be only possible in WOFF 1.0 anyway).

* src/sfnt/sfobjs.c (sfnt_open_font): Guard WOFF code with
`FT_CONFIG_OPTION_USE_ZLIB` block.
Guard WOFF2 code with `FT_CONFIG_OPTION_USE_BROTLI` block.

* src/sfnt/sfwoff.c, src/sfnt/sfwoff.h: Guard files with
`FT_CONFIG_OPTION_USE_ZLIB` blocks, not parts of the code.

* src/sfnt/sfwoff2.c, src/sfnt/sfwoff2.h, src/sfnt/woff2tags.c,
src/sfnt/woff2tags.h: Guard files with `FT_CONFIG_OPTION_USE_BROTLI` blocks,
not parts of the code.

Fixes #1111.

* src/sfnt/sfwoff2.c (compare_tags, find_table, woff2_open_font):
Use 32-bit tag.
* src/sfnt/woff2tags.[ch] (woff2_known_tags): Use static storage and
return 32-bit tag.

David Turner e13391333f Make macros for header file names optional. 
We no longer have to take care of the 8.3 file name limit; this
allows us (a) to introduce longer, meaningful file names, and (b) to
avoid macro names in `#include' lines altogether since some
compilers (most notably Visual C++) doesn't support this properly.

*/*: Replace

   #include FOO_H

with

   #include <freetype/foo.h>

or something similar.  Also update the documentation.

Werner Lemberg 60c52f0edb [woff2] Formatting; some comments. 2019-08-27 10:29:59 +02:00
Nikhil Ramakrishnan 86803acd2a [woff2] Check whether known tag is in array bounds. 
If table tag is not 0x3f, we expect a value between 0 and 62.  If
this is not the case, exit with errors.

* src/sfnt/sfwoff2/c: Check whether table tag makes sense.

* src/sfnt/woff2tags.c: Return 0 if tag is out of bounds.
 2019-08-27 10:06:03 +02:00
Nikhil Ramakrishnan 7a1639bc1e [woff2] Get known tags from function. 
Change `KnownTags' to a function (`woff2_known_tags').  This avoids
introducing a global constant array.  This function returns the
specified index without *any* checks.  The caller must ensure that
`index' is within array limits.

* src/sfnt/sfwoff2.c (woff2_open_font): Change `KnownTags[...]'
notation to `woff2_known_tags( ...  )'.

* src/sfnt/woff2tags.c: Perform changes.

* src/sfnt/woff2tags.h: Update definitions.

the specification.  See

for details.

* src/sfnt/woff2tags.c, src/sfnt/woff2tags.h: New files.
