f00a4de92b fixed two bugs: 
- one bug in the auto-hinter that could cause some program
    crashes with certain fonts

  - fixed the loading of the font matrix "offset" parameters
    in Type 1 and CID-keyed fonts..

8bb45ec8fb Fixing comment in unixddef.mk which caused a trailing blank. 
Adding a new error, FT_Err_Invalid_Pixel_Size (used in winfnt.c)

Fixing FT_Read_Fields() which failed for ft_frame_{bytes,skip}.  This bug
disabled the Winfont driver.

Minor formatting issues.

4e38576a97 fixed a bug that happened when rendering spaces 
in monochrome mode..

actually, when outline.num_points == 0, it is legal
to have outline.points == 0 too. The code did return
a FT_Err_Invalid_Outline error incorrectly then because
the checks were not performed in the correct order

a8194a97db - added a new function called FT_SqrtFixed to compute the 
16.16 square root of a 16.16 number (this could come handy
  in a later version of the auto-hinter)

- small fixes to the smooth renderer. It used to use way too
  much line segments when drawing beziers !!

80b96f350c fixed some bugs in the caching sub-system and improved 
its API to enable many kinds of glyph images..

(note that the "ftview" program has been changed to
use the caching sub-system, "ftmulti" and "ftstring"
should come soon).

e12e313a04 a small optimisation that should speed things a bit. 
I'm surprised I didn't do it before..

5878a6d2ad a fix to the computation of the font "text height" (i.e. the 
baseline-to-baseline distance).

Unfortunately, we cannot rely on the OS/2 fields, like
sTypoAscender or usWinAscent to compute it. Rather,
we only look at the horizontal header's content. In case
the "line gap" is set to 0, we compute the text height as
115% of the ascender+descender value..

(this percentage is based on the values found in many
Windows fonts).

35db73220c - fixed an horrible FT_LOAD_RENDER bug that returned empty 
bitmaps !!

- tested and fixed the image cache object. I'm performing a
  few more checks though, and we'll call the cache sub-system
  completed !!

98d2701c58 changed the FTC_Manager_New function to accept "max_faces" and

b466a7650c The FreeType Caching Subsystem - first lines of code

correctly.. more information will follow..

a39acf55f7 updated "psaux" and "type1z". 
The Type 1 driver now completely relies on "psaux". I
now need to change the CID driver accordingly, then
finally move the Type 2 parsing routines to "psaux"
when appropriate..
 2000-08-23 02:47:57 +00:00

9748807412 the psaux module is now nearly completed 
the "type1z" driver uses it to parse Type 1 charstrings
(not to parse the Type 1 token stream yet though)..

David Turner
f95a603117 minor updates to the "psaux" module. 
Werner, please do not start re-formatting my experimental
code until I declare it "finished", because I still make big
changes to it that create lots of CVS conflicts..

thanks for your work, anyway :-)

29a90e2610 Updating unix/ftconfig.in to recent config/ftconfig.h changes. 
More C++ fixes: Introducing LOCAL_FUNC_X for local functions used in
function pointers (there are no local anonymous functions in C++) and
FT_CPLUSPLUS (instead of FT_EXPORT_VAR) to define linkage of structures
which contain function pointers.

3a89c2a4ac Removing FT_MAKE_OPTION_SINGLE_LIBRARY_OBJECT. It has never worked. 
Instead, define BASE_DEF() and BASE_FUNC() similarly to FT_EXPORT_DEF() and
FT_EXPORT_FUNC(), respectively, allowing the programmer to define proper
types and/or export lists for multiple DLLs if necessary (e.g. ftbase.dll --
standalone, fttype1.dll -- needs ftbase.dll, etc.).

The library is finally compiling and linking natively with a C++ compiler!

e72c9fec17 Simplifying the FIELD_* and FRAME_* macros. Before calling these macros, 
you should #define FT_STRUCTURE to the structure which will be filled.

Replaced FT_FIELD_REF with FT_FIELD_SIZE, FT_FIELD_SIZE_DELTA, and
FT_FIELD_OFFSET to make the code more readable; additionally, it should be
more portable because we no longer cast a pointer to an FT_UShort (which
e.g. fails with Sun's C++ compiler) but computes the difference between two
pointers which is guaranteed to work.

Fixing warnings (and C++ errors) while using Sun's latest cc and CC
incarnations.  Most of them are related to variable shadowing.

e97cb9127d FT_Done_Stream(): do stream->close = 0 after calling stream->close(); this makes it safe to call FT_Done_Stream() more than once.

c5cdf8bcf1 re-adding a "unix-dev.mk". Debugging libtool output

666b11d59c small fix to the auto-hinter: 
the filling direction of each glyph is now re-computed on the
fly, given that we cannot rely on the "flags" field of the
source outline..

this fixes problems with many fonts, including the Arphic ones
(not to say that CJK fonts are handled better for now though..)

321cd27d0f Removing compiler warnings about unused portions of code. 
Now unix.in uses absolute paths also to overcome problems with libtool.
To do that in a consistent way I had to modify the rules how to handle
$OBJ_DIR (and consequently $LIB_DIR): You should set $OBJ_DIR explicitly
on the command line (or environment).

c49f69cb8c some welcome fixes related to the auto-hinter: 
- removed a stupid memory leak

  - fixed the weird metrics hinting (the horizontal edges were used,
    instead of the vertical one, to compute the metrics adjustments,
    silly, silly, silly).

there is still some bugs that I'm looking at though, but we're
very near the release..
