1c0d4acb25 Fine-tuned a lot of tracing levels to make them more functional with ftview. 
Added a lot of \n to tracing messages.

Fixed a serious bug in loading SBit offsets (missing parentheses around a
xxx ? yyy : zzz construct).

Replaced most GET_xxx() functions with calls to READ_Frame() in ttsbit.c

5617726108 ftview now has two new options: -d activates debugging, and -l sets the 
trace level.

Since FT2 is still beta, I've activated the FT_DEBUG_xxx macros by default.

To make reasonable output, I've changed some TRACEx macros to other levels.

6b0bf34665 slight change to the smooth renderer to make it compile 
stand alone with the _STANDALONE_ macro defined..
See comments inside it "src/base/ftgrays.c"

0c8cde2e05 ftgrays.c: Formatting. It seems to me that _STANDALONE_ doesn't work yet... 
Will it ever work?  If not, the unused code should be removed.

ftconfig.h, ftobjs.h: Fix my last fix of the UNUSED() macro.
 2000-05-30 20:10:06 +00:00

a519b3b7a3 Formatting, fixing descriptions. 2000-05-29 20:46:12 +00:00
David Turner
b1677a87ca changed the SFNT driver slightly to add more robust 
checking based on the "search_rang", etc.., fields of
the sfnt header..

This avoids problems (like certain Type 1 multiple masters
incorrectly recognized as trueType files)..
 2000-05-29 20:37:41 +00:00
David Turner
241e151eb2 oops, forgot to commit these files 2000-05-28 17:15:37 +00:00
David Turner
2e421319fc moved a lot of things from the TrueType driver to the SFNT 
module (whose interface has changed, by the way)

This allows even more code re-use between TrueType and
OpenType formats..
 2000-05-26 22:13:17 +00:00

fea68c6800 fixed two minor bugs: 
- the glyph index was not checked in FT_Load_Glyph
  - the "type1" driver didn't read the FontBBox and FontMatrix
    correctly..
 2000-05-26 06:40:49 +00:00
David Turner
936d2e072b a small change to allow the "type1" driver to detect 
multiple master fonts and return an error code that allows
the "type1z" driver to load them after..
 2000-05-26 02:16:06 +00:00
David Turner
7c388ba491 added support for multiple master fonts in "type1z". It is 
now working, but there is no way currently to change the default
weight vector (tested with custom vectors though).

Note that you should remove the "type1" driver from the
module list to be able to test it..
 2000-05-26 02:07:40 +00:00
David Turner
1c9a1cab3f important modifications to the Type1z driver

FT_TRACE calls to use %p instead of %lx when dumping
a pointer address
 2000-05-18 16:18:05 +00:00
David Turner
109fcf6086 fixed the sbit loader (src/base/sfnt/ttsbit.c) 
introduced a new load flag (FT_LOAD_CROP_BITMAP) used
to indicate that we want embedded bitmaps to be cropped..

Thanks a lot to Yamano-uchi, Hidetoshi
 2000-05-17 23:35:37 +00:00
David Turner
3475e7fba3 removed TT_MAX_SUBGLYPHS macro, there is no static 
limit on the number of subglyphs in a TrueType font..

changed the default number of gray levels used by the
smooth renderer to 256 (instead of 128). Of course, the
human eye can't tell a difference ;-)

c30aea9846 another massive changes in order to completely avoid 
compiler warnings with GCC + "-ansi -pedantic -Wall -W"
and LCC.

(its pre-processor is broken !!)

Updated the BUILD document too
 2000-05-12 15:01:18 +00:00
David Turner
bfe2f98f1f a new massive grunt work. Redefined the EXPORT_DEF, 
EXPORT_FUNC, BASE_DEF and BASE_FUNC macros to
let them take an argument..

This is needed to compile the library as a DLL on some platforms
that have different compiler conventions..
 2000-05-12 12:17:15 +00:00
David Turner
4f2c5544bb additional changes, this time in order to pass extra parameters 
to font drivers when creating a new face object.

37379e2170 major changes to the library: 
- there is now a "convenience" API to manage glyphs in
   "include/ftglyph.h". See the demo program "ftstring" for
   an example..

  - the raster interface has been changed in order to allow
    direct composition through user-provided callbacks. This
    has been tested but isn't demonstrated for now in "demos"

 - the FT_LOAD_NO_RECURSE flag is supported, as this is
   required by some new code in the auto-hinting engine

 - some bug fixed in FT_MulFix which made FT_xxx_Transform
   return incorrect results..

febe3fbeba A first check of FT2's Make system. Many smaller and larger bugs have been 
fixed:

. Removing unused variables.

. detect.mk files now must provide $(CONFIG_FILE) and not $(CONFIG_RULE).

. ansi.mk will now be really used as a fallback if the detect mechanism
  fails.

. ANSIFLAGS will now be really used (fixing a typo).

. `make clean' now works (again two typos).

. Detection of gcc on Unix has been fixed (using the `-v' option instead of
  `--version').

. `make devel' now works (on Unix).

. Fixing *again* a bug in demos/graph/x11/rules.mk to allow multiple use
  of `-L' compiler options.

. $(BASE_H) now contains a few more header files.

As usual, a lot of formatting (not finished yet).

0dd3434801 The Type 1 experimental driver was updated 
- small reduction of the code size of "t1encode.c"
- removed the hinter (not useful with the upcoming
  auto-hinter..)
- updated "t1load.c" to reduce warnings with Visual C++
- considerably changed the glyph loader (it is simpler)

Beware, this code is still experimental, and is _not_
debugged. I don't even guarantee that it works for
now

8f43c714a5 A major refresh of the TrueType driver : 
- some #ifdefs were included in order to _not_
  compile support for the bytecode interpreter
  when FT_CONFIG_OPTION_BYTECODE_INTERPRETER
  is not defined in "ttconfig.h"

- the glyph loader has been seriously re-designed. It is now
  smaller, simpler and should load composites a bit faster

- works with the TrueType debugger

2dfb5aca28 added a new experimental Type 1 driver. This version sports several 
improvements compared to "src/type1". Briefly :

  - the postscript-like interpreter is now gone. We now perform
    pattern-matching to load our font content. The resultant code
    is much faster, smaller, and easier to maintain.

    For a more detailed description, see the comments at the start
    of "src/type1z/t1objs.c"

  - the glyph loader will be greatly simplified really soon, and the
    clumsy hinter will be ditched in favor of a more general auto-hinting
    module (when we get one).

    The goal is to strip down the Type1 driver to about 15-20 Kb.

This is still an experimental version. It is added to the repository
for archiving. You should not try to use it for now (it won't work
because some crucial parts are _knowingly_ ignored for now !).

Note that the "old" type1 driver will probably move to the "demos/src"
directory, in order to show how one can replace one given font driver
at runtime (and to provide the functionality of the "t1dump" program).

d42c68e855 many new small, but important, changes there: 
- modified the interface of the "sfnt" module. There is now a function
    called "load_format_tag", and another called "load_directory".

    The first one is in charge of returning the 4-byte tag located at
    the beginning of a given font file. It understand TrueType collections
    and parses them automatically

    The second loads the table directory that is located just after
    the format tag.

    This is useful, because the "SFNT" storage scheme can be used by
    several distinct formats, each with its own format tag.

    The TrueType driver now checks the format tag in "src/truetype/ttobjs.c"

  - made some changes to "src/shared/t1types.h" to clearly separate the
    Type 1 font content from the rest of the T1_Face structure. This
    will be useful when adding the CFF/Type2 driver that will be able
    to reuse the "T1_Font" structure within a "TT_Font" one (which
    really describes a SFNT-based font file).

    Some changes in "src/type1" were thus performed to reflect this.
    Note that the current type1 driver will be discontinued in a
    distant future. More on this later..

76bbd5793f the T1_Face definition changed slightly to clearly separate the 
Type 1 font content from the rest. This implied some changes to
the following files.

3ba47068a6 some updates to the "rules.mk" files. Basically, we now 
use "$(FT_COMPILE)" instead of "$(FT_CC)" in order to
compile the library.

$(FT_COMPILE) uses the $(ANSI_FLAGS) variable used to
define ANSI-compliance flags for the current compiler. It is used
to compile the library exclusively (some demo programs will _not_
compile properly with these flags set).
