the newest XFree86 4.0 B&H Type 1 fonts !!
2000-04-14 11:22:17 +00:00
David Turner 90a36c5522 a small improvement to the Type 1 hinter, that
comes from research with the auto-hinter. Nothing
fancy but gets rid of the un-normalized widths :-)
2000-04-04 18:21:45 +00:00
David Turner 82942cc279 simple fix required by the auto-hinting module

Just van Rossum 3562d014e6 minor improvements, mainly to the PFB testing code... 2000-03-28 19:41:56 +00:00
David Turner 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..
2000-03-28 11:22:31 +00:00

Just van Rossum 59d8ac4615 formatting: some tabs replaced by spaces 2000-03-05 15:59:09 +00:00
Werner Lemberg 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).

David Turner 18789bfe9f Added prototype OpenType Layout support
sources. This is not a port of the OTL extension
of FT 1.x, as it uses a very different design.

These sources are placed here for comments
and peer-review
2000-02-15 12:53:31 +00:00
David Turner dbe4872bf0 removed obsolete source file 2000-02-14 16:45:40 +00:00

module doesn't support embedded bitmaps and
postscript names..
2000-02-13 13:38:27 +00:00
David Turner 7663f22288 Added support for the "attach_file" format-specific driver
interface, used to implement FT_Attach_File.

Note, this is currently very lightly tested..
2000-02-13 13:37:38 +00:00
David Turner 818336fdf4 Added the function FT_Read_Fields, it acts as a
finite-state automata to load large TrueType tables
in object structures.

This is experimental, don't mess too much with it,
thanks :-)
2000-02-13 13:36:53 +00:00
David Turner 3188a3a112 Sorry, forgot some changes needed to get rid of
t1encode.[hc]. Here they come..
2000-02-13 13:34:18 +00:00
David Turner 5ae1259c03 removed the "t1encode" files which are now
obsolete with the "psnames" module
2000-02-10 19:17:24 +00:00
David Turner 7433655cbd Some changes. The SFNT driver is able to return
Postscript glyph names even when the "psnames"
module is not used..
2000-02-10 19:14:48 +00:00
David Turner c3122c98ce added some comments 2000-02-10 19:11:30 +00:00

is undefined..
2000-02-10 16:17:23 +00:00
David Turner a8635cc626 Very simple AFM Parser 2000-02-10 16:15:11 +00:00
David Turner cda32b71ba added the FT_Attach_File function to enable AFM
parsing.

Now with a simple AFM parser in order
to read the kerning table..
2000-02-10 16:08:36 +00:00
David Turner 51d4e28daf New version of the Type 1 driver.
Generates a Unicode charmap on the fly
through the "psnames" module..

Now, we only need to support afm/pfm
files (and maybe multiple masters) to call
this driver finished !!
2000-02-10 13:11:43 +00:00
David Turner 5c9a571a5a new psnames module 2000-02-10 13:10:32 +00:00
David Turner 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

- David
2000-02-02 12:20:53 +00:00
David Turner 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
2000-02-02 12:16:19 +00:00
David Turner 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).
2000-01-27 14:02:04 +00:00
David Turner 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..
2000-01-27 13:56:02 +00:00
David Turner 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.
2000-01-27 13:35:16 +00:00
David Turner 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).
2000-01-17 11:25:57 +00:00
David Turner 3b925ef744 fixed a minor bug in the computation of the vertical
metrics top-side bearing
2000-01-17 11:22:59 +00:00
David Turner fdc225b153 fixed another small bug in the FT_Read_xxxx functions
(they didn't updated the stream position in the case of
disk-based streams. This went un-noticed under Linux
which uses memory-mapped files by default)
2000-01-17 11:21:49 +00:00
David Turner 8cd9575c27 fixed small bug 2000-01-17 11:21:00 +00:00

Fixed cleaning rules for the demo programs.
2000-01-17 08:24:22 +00:00
Werner Lemberg 9ab7c3c37e Fixed compilation bug for standalone mode. 2000-01-15 12:43:27 +00:00
David Turner cef95a09d7 Yet another improvements to the scan-converter. Some macros were
introduced to use a constant precision and dynamic bezier decomposition
thresholding, leading some performance improvements.

Note that by now, the "high_precision" field of a FT_Outline
is ignored by the raster..
2000-01-14 15:36:00 +00:00
David Turner 4f2d5b9a48 fixed a bug which prevented the raster from correctly
performing horizontal dropout control..
2000-01-13 18:20:28 +00:00
David Turner 454a428542 fixed a bug which caused some font family and style
names to be incorrectly ignored..

  doc fixes.

ftdebug.c:
  formatting.

ftdebug.h:
  making makros `;'-safe (i.e., they can now be used within if-else clauses
  without side effects resp. don't produce a single `;').
2000-01-08 17:10:33 +00:00
David Turner fc1f989446 Finally, the TrueType driver was completely audited. The code should
now be 100% compatible with the implementation in FreeType 1.x.

It's now time to make a new tag for the repository :-)

FT2 beta, and was moved to "src/sfn")
2000-01-07 14:01:59 +00:00
Werner Lemberg 17ae985d38 ftbbox.h: FT_Get_Outline_BBox() must be called FT_Raster_GetBBox().
ftcalc.c: Added a missing closing paranthesis in 64bit version of
          FT_MulFix().

Some formatting; updating copyright.
2000-01-02 09:41:30 +00:00
David Turner 433bc53fb6 Additional improvements to make the anti-aliasing even faster :-)
As previously, this is only noticable for sizes over 64 pixels.
1999-12-30 12:28:03 +00:00
David Turner 5951ce9fc6 updated the CHANGES file
+ some basic formatting cleaning
1999-12-29 00:53:44 +00:00
David Turner 10effdf61e Added the rules files `module.mk' to "sfnt", "truetype" and "type1" to
reflect the new modules/drivers list management performed through the
file `freetype2/config/modules.mk'

Changed the driver header files to reflect the new modules/drivers
list management. We get rid, at last, of the infamous pre-processor
tricks used to build the list at compile time.

`src/base/ftinit.c' is also modified to reflect the changes..
1999-12-29 00:22:24 +00:00
