heavy internal modifications to introduce the concept of
"module services". This is the first step towards a massive
simplification of the engine's internals, in order to
get rid of various numbers of hacks.
Note that this changes will break source & binary compatibility
for authors of external font drivers.
Maybe 2.1.6 will be called 2.2.0 after all :-)
FT_MEM_MOVE.
* include/freetype/freetype.h (FT_ENCODING_SJIS, FT_ENCODING_GB2312,
FT_ENCODING_BIG5, FT_ENCODING_WANSUNG, FT_ENCODING_JOHAB): New
enumerations of FT_Encoding. The FT_ENCODING_MS_* variants except
FT_ENCODING_MS_SYMBOL are now deprecated.
Updated all users.
* docs/CHANGES: Document it.
include/freetype/freetype.h (FT_Bitmap_Size): `height' is now
defined to return the baseline-to-baseline distance. This was
already the value returned by the BDF and PCF drivers.
The `width' field now gives the average width. I wasn't able to
find something better. It should be taken as informative only.
New fields `size', `x_ppem', and `y_ppem'.
* src/pcf/pcfread.c (pcf_load_font): Updated to properly fill
FT_Bitmap_Size.
Do proper rounding and conversion from 72.27 to 72 points.
* src/bdf/bdfdrivr.c (BDF_Face_Init): Updated to properly fill
FT_Bitmap_Size.
Do proper rounding and conversion from 72.27 to 72 points.
* src/sfnt/sfobjs.c (sfnt_load_face): Updated to properly fill
FT_Bitmap_Size.
* src/winfonts/winfnt.c (FNT_Face_Init): Updated to properly fill
FT_Bitmap_Size.
Redesigning the FNT driver to return multiple faces, not multiple
strikes. At least one font (app850.fon from WinME) contains
different FNT charmaps for its subfonts. Consequently, the previous
design of having multiple bitmap strikes in a single font face fails
since we have only one charmap per face.
* include/freetype/internal/fnttypes.h (FNT_Size_Rec): Removed.
(FNT_FaceRec): Remove `num_fonts' field and replace `fonts' with
`font'.
* src/base/ftwinfnt.c (FT_Get_WinFNT_Header): Updated.
* src/winfonts/winfnt.c (fnt_font_load): Don't set pixel_width equal
to pixel_height.
(fnt_face_done_fonts): Removed.
(fnt_face_get_dll_fonts): Renamed to...
(fnt_face_get_dll_font): This. Add second function argument to
select face index.
Updated to load just one subfont.
(fnt_font_done, FNT_Face_Done): Updated.
(FNT_Face_Init): Handle `face_index'.
Updated.
(FNT_Size_Set_Pixels): Simplified; similar to BDF and PCF, the
bitmap width is now ignored.
(FNT_Load_Glyph): Updated.
Fix glyph index computation.
(winfnt_driver_class): Updated.
computation of glyph_index.
(FNT_Size_Set_Pixels): To find a strike, first check pixel_height
only, then try to find a better hit by comparing pixel_width also.
Without this fix it isn't possible to access all strikes.
Also compute metrics.max_advance to be in sync with other bitmap
drivers.
* src/base/ftobjs.c (FT_Set_Char_Size): Remove redundant code.
(FT_Set_Pixel_Size): Assign value to `metrics' after validation of
arguments.
Synchronize computation of height and width for bitmap strikes. The
`width' field in the FT_Bitmap_Size structure is now only useful to
enumerate different strikes. The `max_advance' field of the
FT_Size_Metrics structure should be used to get the (maximum) width
of a strike.
* src/bdf/bdfdrivr.c (BDF_Face_Init): Don't use AVERAGE_WIDTH for
computing `available_sizes->width' but make it always equal to
`available_sizes->height'.
* src/pcf/pcfread.c (pcf_load_font): Don't use RESOLUTION_X for
computing `available_sizes->width' but make it always equal to
`available_sizes->height'.
* src/truetype/ttdriver.c (Set_Pixel_Sizes): Pass only single
argument to function.
* src/psnames/psmodule.c (ps_unicode_value): Handle `.' after
`uniXXXX' and `uXXXX[X[X]]'.

ft_glyph_bbox_subpixels, ft_glyph_bbox_gridfit,
ft_glyph_bbox_truncate, ft_glyph_bbox_pixels): Replaced with
FT_GLYPH_BBOX_UNSCALED, FT_GLYPH_BBOX_SUBPIXELS,
FT_GLYPH_BBIX_GRIDFIT, FT_GLYPH_BBOX_TRUNCATE, FT_GLYPH_BBOX_PIXELS.
The lowercase variants are now (deprecated aliases) to the uppercase
versions.
Updated all other files.

ft_module_renderer, ft_module_hinter, ft_module_styler,

FT_MODULE_RENDERER, FT_MODULE_HINTER, FT_MODULE_STYLER,
FT_MODULE_DRIVER_SCALABLE, FT_MODULE_DRIVER_NO_OUTLINES,
FT_MODULE_DRIVER_HAS_HINTER.
The lowercase variants are now (deprecated aliases) to the uppercase
versions.
Updated all other files.
* src/base/ftglyph.c (FT_Glyph_Get_CBox): Handle bbox_mode better
as enumeration.
* src/pcf/pcfdrivr.c (pcf_driver_class), src/winfonts/winfnt.c
(winfnt_driver_class), src/bdf/bdfdrivr.c (bdf_driver_class): Add
the FT_MODULE_DRIVER_NO_OUTLINES flag.
. In all makefiles `/' is used as the path separator. The
conversion to the real path separators is done as late as
possible using $(subst ...).
. $(HOSTSEP) no longer exists. Now, $(SEP) gives the path separator
for the operating system, and the new $(COMPILER_SEP) the path
separator for the compiler tools.
. $(BUILD) has been renamed to $(BUILD_DIR). In general, all
directory variables end with `_DIR'. The variants ending in `_'
(like `BASE_' have been removed).
The following ChangeLog entries only describe changes which are
not related to the redesign.
* builds/beos/beos-def.mk (BUILD_DIR): Fix typo.
* builds/compiler/watcom.mk (LINK_LIBRARY): Fix linker call to avoid
overlong arguments as suggested by J. Ali Harlow
<ali@avrc.city.ac.uk>.
* builds/dos/dos-wat.mk: New file.
* builds/freetype.mk (FREETYPE_H): Include header files from the
`devel' subdirectory.
* builds/os2/os2-dev.mk, builds/unix/unixddef.mk,
builds/unix/unixddef.mk, builds/win32/w32-bccd.mk,
builds/win32/w32-dev.mk (BUILD_DIR): Fix path.
* builds/unix/configure.ac, builds/unic/configure: Updated.
* builds/unix/unix-def.in (DISTCLEAN): Add `freetype2.pc'.
* devel/ftoption.h: Updated.
argument.
(bdf_get_font_property): Use `const' for third argument.
Updated all callers.
* src/bdf/bdfdrivr.c (BDF_Face_Init): Set pixel width and height
similar to the PCF driver.
* src/bdf/bdf.h (_hashnode): Use `const' for `key'.
Updated.
* src/gzip/ftgzip.c: C++ doesn't like that the array `inflate_mask'
is declared twice. It is perhaps better to modify the zlip source
files directly instead of this hack.
(zcalloc, zfree, ft_gzip_stream_close, ft_gzip_stream_io): Add casts
to make build with g++ successful.
* include/freetype/internal/ftobjs.h, src/base/ftobjs.c, src/bdf/bdfdrivr.c,
src/pcf/pcfdriver.c, src/pfr/pfrsbit.c, src/sfnt/ttsbit.c,
src/type42/t42objs.c, src/winfonts/winfnt.c: introduced three new functions
to deal with glyph bitmaps within FT_GlyphSlot objects. these are:
ft_glyphslot_free_bitmap
ft_glyphslot_alloc_bitmap
ft_glyphslot_set_bitmap
these are much more convenient to use than managing the FT_GLYPH_OWN_BITMAP
flag manually. the font drivers have been modified to use them as well.
* src/cache/ftlru.c: fixed an invalid assertion check
src/base/ftbdf.c, src/bdf/bdfdrivr.c, src/pcf/pcfdrivr.c,
src/pcf/pcfread.h:
adding a new API, named FT_Get_BDF_Property to retrieve the BDF
properties of a given PCF or BDF font
* include/freetype/config/ftoption.h, src/gzip/ftgzip.c: added
support for the FT_CONFIG_OPTION_SYSTEM_ZLIB option, used to specify
the use of system-wide zlib.
Note that this macro, as well as FT_CONFIG_OPTION_BYTECODE_INTERPRETER,
is not #undef-ed anymore. This allows the build system to define them
depending on the configuration (typically by adding -D flags at
compile time).
* src/sfnt/ttcmap0.c (tt_face_build_cmaps): removed compiler warnings
in optimized mode relative to the "volatile" local variables. This was
not a compiler bug after all, but the fact that a pointer to a volatile
variable is not the same than a volatile pointer to a variable :-)
the fix was to change "volatile FT_Byte* p"
into "FT_Byte* volatile p"
* src/pfr/pfrload.c, src/pfr/pfrdrivr.c, src/gzip/inftrees.c: removed
compiler warnings in optimized modes
* src/gzip/*.[hc]: modified our ZLib copy in order to prevent exporting
any zlib function names outside of the component. This prevents linking
problems on some platforms, when applications want to link FreeType
_and_ ZLib together.
2002-11-05 Juliusz <jch@pps.jussieu.fr>

constant.
* builds/amiga/include/freetype/config/ftmodule.h: Updated.
want to list them all here. The operations performed were all logical
transformations of the sources:
- trying to convert all enums and constants to CAPITALIZED_STYLE, with
#define definitions like
#define my_old_constants MY_NEW_CONSTANT
- big, big update of the documentation comments
* include/freetype/freetype.h, src/base/ftobjs.c, src/smooth/ftsmooth.c,
include/freetype/ftimage.h: adding support for LCD-optimized rendering
though the new constants/enums:
FT_RENDER_MODE_LCD, FT_RENDER_MODE_LCD_V
FT_PIXEL_MODE_LCD, FT_PIXEL_MODE_LCD_V
this is still work in progress, don't expect everything to work correctly
though most of the features have been implemented.
* adding new FT_LOAD_XXX flags, used to specify both hinting and rendering
targets:
FT_LOAD_TARGET_NORMAL :: anti-aliased hinting & rendering
FT_LOAD_TARGET_MONO :: monochrome bitmaps
FT_LOAD_TARGET_LCD :: horizontal RGB/BGR decimated hinting & rendering
FT_LOAD_TARGET_LCD_V :: vertical RGB/BGR decimated hinting & rendering
note that FT_LOAD_TARGET_NORMAL is 0, which means that the default
behaviour of the font engine is _unchanged_.

PCF_Char_Get_Index): Increase result by 1 for normal cases.
(PCF_Glyph_Load): Decrease index by 1.

(BDF_Get_Char_Index) [!FT_CONFIG_OPTION_USE_CMAPS]: Use only
conditionally.
(BDF_Face_Init): Handle `AVERAGE_WIDTH' and `POINT_SIZE' keywords.
Implement new cmap handling.
(bdf_driver_class): Updated.
* src/sfnt/ttload.c, src/bdf/bdflib.c: removing compiler warnings
* src/type42/t42objs.c: removed the bug that prevented un-hinted
outlines to be loaded
(_bdf_parse_glyphs): Use correct size for allocating
`font->unencoded'.
(bdf_load_font): Free array conditionally.
Return proper error code in case of failure.
* src/bdf/bdfdrivr.c (BDF_Face_Init): Make it more robust against
unusual fonts.

src/winfonts/winfnt.c, src/type42/t42drivr.c, src/bdf/bdfdrivr.c
[FT_CONFIG_OPTION_DYNAMIC_DRIVERS]: Completely removed. It has
been never used.
(parse_font_matrix): Remove unnecessary code.
(parse_sfnts): Initialize some variables.
(t42_driver_class) [TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Use
ft_module_driver_has_hinter conditionally.

* src/cache/ftcsbits.c (ftc_sbit_node_load): Initialize it.
Adding a driver for BDF fonts written by Francesco Zappa Nardelli
<Francesco.Zappa.Nardelli@ens.fr>. Heavily modified by me to
better adapt it to FreeType, removing unneeded stuff. Additionally,
it now supports Mark Leisher's BDF extension for anti-aliased
bitmap glyphs with 2 and 4 bpp.
