834b53ed0e Simplied glyph width processing code and the comments pertaining to it. 2000-11-27 03:23:50 +00:00
Tom Kacvinsky
6037f08474 In function T2_Parse_CharStrings, modified glyph width assignment code 
to be more robust.  The code now takes into account glyphs that

   1. have the width given as it is, rather than as a difference against
      `nominal_width', and

   2. have the width operand specified before one of the h/r/vmoveto
      commands or the endchar command.

6dd303db0d * builds/ansi/ansi.mk: Fix inclusion order of files.

27695e5dbf * src/type1/t1load.c (parse_subrs, parse_charstrings): Use decrypt 
function from PSAux module.

* src/type1/t1parse.c (T1_Done_Parse): Renamed to...
(T1_Finalize_Parser): New function (to avoid name clash with a
function in the PSAux module).
(T1_Decrypt): Removed since it it duplicated in the PSAux module.
(T1_Get_Private_Dict): Added `psaux' as new parameter; use decrypt
function from PSAux module.

* src/type1/t1parse.h: Adapted.

3da9d565ee In function T2_Get_String, we called T2_Get_Name with an string id 
that was off by one.

a51b45c607 Make sure that parse_t2_real correctly parses a CFF real number. Added more comments 
to the function.

c3dfbde074 In function T2_Init_Face, make sure that root->num_faces gets 
set when loading a pure CFF font, and change units_per_EM to
1000 for a pure CFF font.

cd1afc4ef1 fixed a bug in "docs/glnames.py" which caused he generation of an 
invalid Mac names table in the file "src/psnames/pstables.h".

This caused FT_Get_Glyph_Name to return invalid glyph names
for certain TrueType fonts..

f96594faf0 integrated Yamano-Uchi changes to the base source code. However, 
I've made a few modifications:

  - there is no new field named "driver" in "FT_SizeRec"

  - the new fields in "TT_SizeRec" are:

       strike_index   :: value 0xFFFF means "no sbit strike selected"
       strike_metrics :: the FT_Size_Metrics structure corresponding to
                         the currently selected strike

  - the code in "ttload.c" has been somewhat cleaned up too

thanks a lot, Y-U !!

25dee217ab some updates to the cache sub-system. some methods were moved from 
the concrete "FTC_Image_Cache" and "FTC_SBit_Cache" to the abstract
"FTC_Glyph_Cache" and "FTC_Chunk_Cache", respectively..

note: this is not the end of changes to the cache sub-system

dc72aff43d Finishing David's latest changes (there were some errors in it). 2000-11-04 08:33:38 +00:00
David Turner
54e7574946 defining new types to hold "internal" fields of public 
objects:

  FT_Face_Internal, FT_Size_Internal, FT_Slot_Internal

these contain some fields that may change between releases
of FreeType, without affecting the size of FT_FaceRec,
FT_SizeRec, FT_GlyphSlotRec, etc.., which means that
drivers wouldn't need to be recompiled if we only add new
fields to an internal structure..

I plan to hack a few things related to the auto-hinter and
I need this move to ensure that we will not break binary
compatibility between 2.0 and 2.1 :-)

Finishing formatting of cache stuff.

4e4a43631c - completed the abstract chunk cache class 
- started implementin a "small-bitmaps" cache derived from it
- (soon a "metrics" cache will be written too)
 2000-10-28 13:17:11 +00:00
David Turner
9b8f5c4ce1 small updates: 
- reworked slightly the cache manager to better
   differentiate between the abstract class in "ftcglyph.h"
   and the FT_Glyph sub-class in "ftcimage.h", and
   slightly reduced the size of FTC_GlyphNodeRec, saving
   8 bytes on a 32-bit system. Yes, I'm crazy ;-)

 - added build files to compile with LCC on Unix too
   (compile speeds _are_ insane with it). There is unfortunately
   a bug in the version I'm using (LCC 4.1) that prevents it
   to compile FT_MulTo64 correctly (in src/base/ftcalc.c)

   the generated assembly is incorrect, I don't know what
   to do ?? the build files are ok, though..

   you should invoke "make setup lcc" to select them..

a4e2894e03 simple renaming of directories: 
"type1z"  -> "type1"
  "raster1" -> "raster"

note that I didn't rename all files. We'll have to endure
the "z1..." crazyness unless we perform a _big_ sed on
the sources :-)

.notdef.

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).
