Werner Lemberg 8eacad6daa * freetype2/src/sfnt/ttload.c (sfnt_dir_check): Modified to allow a
font to have no `head' table if tables `SING' and `META' are
present; this is to support `SING Glyphlet'.

`SING Glyphlet' is an extension to OpenType developed by Adobe
primarily to facilitate adding supplemental glyphs to an OpenType
font (with emphasis on, but not necessariy limited to, gaiji to a
CJK font).  A SING Glyphlet Font is an OpenType font that contains
the outline(s), either in a `glyf' or `CFF' table, for a glyph;
`cmap', `BASE', and `GSUB' tables are present with the same format
and functionaliy as a regular OpenType font; there are no `name',
`head', `OS/2', and `post' tables; there are two new tables, `SING'
which contains details about the glyphlet, and `META' which contains
metadata.

Further information on the SING Glyphlet format can be found at:

  http://www.adobe.com/products/indesign/sing_gaiji.html

* freetype2/include/freetype/ttags.h (TTAG_SING, TTAG_META): New
macros for the OpenType tables `SING' and `META'.  These two tables
are used in SING Glyphlet Format fonts.

Werner Lemberg 92aa527a1c * builds/amiga/makefile.os4 (WARNINGS), builds/compiler/gcc-dev.mk
(CFLAGS), builds/compiler/gcc.mk (CFLAGS): Remove
-fno-strict-aliasing.


Say you have `(Foo*)x' and want to assign, pass, or return it as
`(Bar*)'.  If you simply say `x' or `(Bar*)x', then the C compiler
would warn you that type casting incompatible pointer types breaks
strict-aliasing.  The solution is to cast to `(void*)' instead which
is the generic pointer type, so the compiler knows that it should
make no strict-aliasing assumption on `x'.  But the problem with
`(void*)x' is that seems like in C++, unlike C, `void*' is not a
generic pointer type and assigning `void*' to `Bar*' without a cast
causes an error.  The solution is to cast to `Bar*' too, with
`(Bar*)(void*)x' as the result -- this is what the patch does.

* include/freetype/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP),
include/freetype/cache/ftcmru.h (FTC_MRULIST_LOOKUP_CMP): Remove
cast on lvalue, use a temporary pointer instead.

FT_MEM_REALLOC, FT_MEM_QALLOC, FT_MEM_QREALLOC, FT_MEM_FREE),
src/base/ftglyph.c (FT_Glyph_To_Bitmap): Cast temporarily to (void*)
to not break strict aliasing.

* src/base/ftinit.c (FT_USE_MODULE): Fix wrong type information.

* builds/unix/configure.ac (XX_CFLAGS): Remove -fno-strict-aliasing.

* src/sfnt/rules.mk (SFNT_DRV_SRC): Don't include ttsbit0.c --
it is currently loaded from ttsbit.c.

David Turner fa0eb0c95f * src/sfnt/ttkern.c (tt_face_load_kern): fixing a small bug which returned

2005-02-27 21:35:50 +00:00
David Turner e5680279b2 * many, many files: several memory optimizations were implemented to
drastically reduce the heap usage of FreeType, especially in the case
  of memory-mapped files. The idea is to avoid loading and decoding tables
  in the heap, and instead access the raw data whenever possible (i.e.
  when it doesn't compromise performance).

  This had several impacts: first, opening vera.ttf uses a ridiculous amount
  of memory (when the FT_Library footprint is accounted for), until you start
  loading glyphs. Even then, you'll save at least 20 Kb compared to the non
  optimized case. performance of various operations, including open/close
  has also been dramatically improved.

  More optimisations to come. The auto-hinter eats memory like crazy? This
  must be stopped...

Werner Lemberg 6d79899362 A new try to synchronize bitmap font access.
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.

* src/sfnt/ttload.c (tt_face_load_hdmx): Don't assign
        num_records until we actually decide to load the table,
        otherwise, we'll segfault in tt_face_free_hdmx.

Werner Lemberg 779afe4b91 * src/winfonts/winfnt.c (FNT_Load_Glyph): Use first_char in
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'.

Werner Lemberg 858f310b80 Completely revised FreeType's make management.
. 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/unix/configure.ac, builds/unic/configure: Updated.
* builds/unix/unix-def.in (DISTCLEAN): Add `freetype2.pc'.


* devel/ftoption.h: Updated.

Werner Lemberg 756655bdf8 * src/base/ftmac.c (FT_New_Face_From_SFNT): s/rlen/sfnt_size/ to
make it compile.

* include/freetype/internal/psaux.h, src/truetype/ttgload.h:
s/index/idx/ to fix compiler warnings.

* src/sfnt/ttcmap0.c (tt_face_build_cmaps): Use more `volatile' to
fix compiler warning.

* src/gzip/ftgzip.c (BUILDFIXED): Removed.

2003-06-05 04:31:05 +00:00
Werner Lemberg 8b88466061 * src/autohint/ahhint.c (ah_hinter_hint_edges): Removed. Just a
wrapper for ah_hint_edges.

with decoder->hint_mode instead of builder->hint_flags.
* src/psaux/t1decode.c (t1_decoder_init): Updated.

* src/base/ftstroker.c (ft_stroke_border_export): s/index/idx/.

* src/sfnt/sfobjs.c (sfnt_load_face): Commented out code which
increased root->height by 15% if the line gap was zero.  There exist
fonts (containing e.g. form drawing characters) which intentionally
have a zero line gap value.
2003-06-03 11:51:43 +00:00
Werner Lemberg f379f43403 * src/sfnt/ttcmap0.c (tt_cmap4_char_next): Select proper start

`segment->link'.
(ah_outline_link_segments): Provide alternative code which does
the same but runs much faster.
Handle major direction also.
(ah_outline_compute_edges): Scale `edge_distance_threshold' down
after rounding instead of scaling comparison value in loop.

* src/autohint/ahhint.c (ah_hinter_align_stong_points): Provide
alternative code which runs faster.
Handle `before->scale == 0'.

* src/autohint/ahtypes.h (AH_SegmentRec): Move some fields down.
(AH_EdgeRec): Move some fields in structure.
New field `scale'.

* src/sfnt/ttcmap0.c (tt_cmap4_char_next): Use binary search.

`pshinter'.

* src/type1/t1gload.c (T1_Load_Glyph): Use `glyph_data_loaded'
only for FT_CONFIG_OPTION_INCREMENTAL.
2003-04-23 19:48:24 +00:00
Werner Lemberg 13c4a4f171 * src/sfnt/ttcmap0.c (tt_cmap4_validate): Provide a weak variant
of the glyph ID bounding check if FT_VALIDATE_TIGHT is not active.

2003-04-23 18:21:48 +00:00
Werner Lemberg b442ca1713 Cleanups. 2003-04-23 15:50:27 +00:00
David Turner 66cbc20978 * docs/*: serious rewriting of the documentation
* 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
2003-03-20 07:04:40 +00:00
David Turner ae26c684db * src/cache/ftccmap.c: the cmap cache now supports UCS-4 charmaps
when available in Asian fonts

    * src/sfnt/ttload.c, src/base/ftobjs.c: changed "asian" to "Asian" in
    comments

    * src/truetype/ttdriver.c (Set_Char_Sizes): fixed a rounding bug when
    computing the scale factors for a given character size in points with
    resolution.
2003-02-25 20:37:50 +00:00
David Turner 79c23ae28a * src/sfnt/ttload.c (sfnt_dir_check): relaxed the "head" table size
verification to accept a few broken fonts who pad the size incorrectly
    (the table should be padded, but its "size" field shouldn't per se
     the spec)
2003-01-22 22:53:55 +00:00
Graham Asher 550fd43946 TrueType typefaces lacking hmtx (horizontal metrics) tables are tolerated if the
incremental interface system is enabaled and an incremental interface
has been specified. This is necessary to support some typefaces passed
from GhostScript.
2003-01-13 10:20:08 +00:00
David Turner 621e488622 2002-12-16 David Turner <david@freetype.org>
* docs/VERSION.DLL: updating document to better explain the differences between
        the three version numbers being used on Unix, as well as provide the AutoConf
        fragment provided by Lars Clausen

        * src/smooth/ftgrays.c (gray_render_conic): fixed small bug that
        prevented bezier arcs with negative vertical coordinates to be rendered
        appropriately


2002-11-27  Vincent Caron <v.caron@zerodeux.net>

        * builds/unix/unix-def.in, builds/unix/freetype-config.in,
        builds/unix/configure.ac, src/gzip/rules.mk, src/gzip/ftgzip.c:
        adding support for system zlib installations when available on the
        target platform (Unix only)
2002-12-16 21:51:24 +00:00
David Turner 60b32e16e7 2002-11-05 David Turner <david@freetype.org>
* 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>

        * src/psaux/psobjs.c (ps_table_add): modified increment loop in
        order to implement exponential behaviour

src/pfr/pfrgload.c, src/pfr/pfrobjs.c, src/pfr/pfrtypes.h,
        Jamfile, src/base/ftobjs.c: adding support for embedded bitmaps to
        the PFR driver, and rewriting its kerning loader / handler to use all
        kerning pairs in a physical font (and not just the first item).

        * src/tools/docmaker/content.py, src/tools/docmaker/sources.py,
        src/tools/docmaker/tohtml.py: fixing a few nasty bugs

        * src/sfnt/ttcmap0.c: the validator for format 4 sub-tables is
        now capable of dealing with invalid "length" fields at the start
        of the sub-table. This allows fonts like "mg______.ttf" (i.e.
        Marriage) to return accurate charmaps.

* src/autohint/ahtypes.h: disabling metrics hinting in the auto-hinter.
        this produces much better anti-aliased text

2002-09-25  Anthony Fok  <anthony@thizlinux.com>

        * src/sfnt/ttcmap0.c: added support for opens___.ttf (it contains
        a charmap that uses offset=0xFFFFU instead of 0x0000 to indicate a
        missing glyph)

Formatting, minor doc fixes.
2002-09-05 15:10:54 +00:00
David Turner b08fe2dc7a * massive re-formatting changes to many, many source files. I don't
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_.

Graham Asher ce12182cfc Modified incremental loading interface to be closer to David Turner's
preferences. The header freetype.h is not now affected, the interface is
specified via an FT_Parameter, the pointer to the interface is hidden in an
internal part of the face record, and all the definitions are in ftincrem.h.

Graham Asher 320da730d4 More work on supporting fonts passed from GhostScript:
sfnt_dir_check now ignores the tables 'glyx' and 'locx' which are hacked-out
versions of 'glyf' and 'loca' in some PostScript Type 42 fonts, and will
generally be invalid.
2002-07-19 11:40:51 +00:00
Graham Asher cd0d1dfa04 Changes to support incremental Type 42 fonts: assume a font has glyphs if it
has an incremental interface object.
2002-07-18 16:38:07 +00:00
David Turner fed59b7cc2 * src/sfnt/ttload.c (TT_Load_SFNT_Header): fixed a recent bug that prevented

David Turner 7acd73fd6a * src/sfnt/ttload.c, src/sfnt/ttload.h, src/sfnt/ttdriver.c: changing
the SFNT loader to check for SFNT-based font files differently. We now
    ignore the range "helper" fields and check the "head" table's magic
    number instead.
2002-07-11 23:41:14 +00:00
David Turner 6ec3f34765 * src/sfnt/ttcmap0.c: fixing the cmap 8 and 12 parsing routines 2002-07-01 21:50:12 +00:00
David Turner a1e45652be * builds/win32/ftdebug.c: added a missing #endif
* 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
2002-06-11 20:35:58 +00:00
David Turner 25a6e3a167 * include/freetype/internal/ftobjs.h, src/autohint/ahglyph.c,
src/base/ftobjs.c, src/objs/fttype1.c, src/sfnt/ttcmap0.c,
    src/smooth/ftgrays.c: changed uses of "setjmp" and "longjmp"
    to "ft_setjmp" and "ft_lonjmp". Removed direct references to
    <stdio.h> and <setjmp.h> when appropriate, to eventually replace
    them with a FT_CONFIG_STANDARD_LIBRARY_H. Useful for the XFree86
    Font Server backend based on FT2.
2002-06-10 23:03:35 +00:00
Werner Lemberg 877ff67887 * src/base/ftnames.c (FT_Get_Sfnt_Name): Don't use FT_STREAM_READ_AT
but FT_STREAM_READ.
Declare `stream' variable.
2002-05-28 06:03:10 +00:00
David Turner 791d83a612 * include/freetype/internal/tttypes.h, src/sfnt/ttload.c,
src/sfnt/sfobjs.c, src/sfnt/sfdriver.c, src/base/ftnames.c:
        fixing the SFNT name table loader to support various buggy fonts.
        it now ignores empty name entries, entries with invalid pointer
        offsets and certain fonts containing tables with broken "storageOffset"
        fields.

        name strings are now loaded on demand, which reduces the memory
        requirements for a given FT_Face tremendously (for example, the
        name table of Arial.ttf is about 10Kb and contains 70 names !!)

        finally, this is a _quick_ fix. The whole name table loader and
        interface will be rewritten in a much more cleanly way shortly,
        once CSEH have been introduced in the sources.
2002-05-27 23:52:01 +00:00

            (e.g. strlen, qsort, setjmp, etc...)

            this eases the porting of FreeType 2 to exotic environments like
            XFree86 modules/extensions..

            also removed many #include <string.h>, #include <stdlib.h>, etc...

David Turner e459d742e6 * include/freetype/internal/ftmemory.h, and a lot of other files !!:
changed the names of memory macros. Examples:

              MEM_Set   => FT_MEM_SET
              MEM_Copy  => FT_MEM_COPY
              MEM_Move  => FT_MEM_MOVE

              ALLOC     => FT_ALLOC
              FREE      => FT_FREE
              REALLOC   = >FT_REALLOC

            FT_NEW was introduced to allocate a new object from a _typed_
            pointer..

            note that ALLOC_ARRAY and REALLOC_ARRAY have been replaced
            by FT_NEW_ARRAY and FT_RENEW_ARRAY which take _typed_ pointer
            arguments.

            This results in _lots_ of sources being changed, but makes the
            code more generic and less error-prone..

              NEXT_Short    => FT_NEXT_SHORT
              NEXT_UShortLE => FT_NEXT_USHORT_LE
              READ_Short    => FT_READ_SHORT
              GET_Long      => FT_GET_LONG
              etc..

            also introduced the FT_PEEK_XXXX functions..
2002-03-22 12:55:23 +00:00
David Turner 7d3a26425b * renaming stream macros. Examples:

          note also that:

          FT_New_Stream( filename, stream ) =>
            FT_Stream_Open( stream, filename )

          (the function doesn't create the FT_Stream structure, it simply

            FT_Stream_Open_Memory( stream, const FT_Byte* base, size )

          FT_Done_Stream => FT_Stream_Close

          note that the name of the stream methods, defined in
          "include/freetype/ftsystem.h" have also been changed without
          problems:

David Turner 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 !!

Werner Lemberg 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 :-)

Werner Lemberg 4a5c142a40 Minor fixes. 2000-08-29 18:37:25 +00:00
David Turner 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).
2000-08-29 16:03:01 +00:00
David Turner 24d7024c44 added draft "psaux" code

Werner Lemberg 29a90e2610 Updating unix/ftconfig.in to recent config/ftconfig.h changes.
More C++ fixes: Introducing LOCAL_FUNC_X for local functions used in

FT_CPLUSPLUS (instead of FT_EXPORT_VAR) to define linkage of structures
which contain function pointers.
2000-08-03 00:03:08 +00:00
Werner Lemberg 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!

Werner Lemberg 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.

  Renamed FT_WordXX to FT_UIntXX.

  Changed a lot of void* to FT_Byte* if related to i/o streams -- FreeType
  always accesses streams byte-wise, so this makes sense IMHO.

  Added a lot of #ifdef __cplusplus to header files (and removed a few).

  Other minor syntax fixes (mostly casts).

  Replaced the variable `private' with `private_dict' -- `private' is

David Turner f0df85ba2a - MAJOR INTERNAL REDESIGN:
A lot of internal modifications have been performed lately on the
    source in order to provide the following enhancements:

      - more generic module support:

        The FT_Module type is now defined to represent a handle to a given
        module. The file <freetype/ftmodule.h> contains the FT_Module_Class
        definition, as well as the module-loading public API

        The FT_Driver type is still defined, and still represents a pointer
        to a font driver. Note that FT_Add_Driver is replaced by FT_Add_Module,
        FT_Get_Driver by FT_Get_Module, etc..


      - support for generic glyph image types:

        The FT_Renderer type is a pointer to a module used to perform various
        operations on glyph image.

        Each renderer is capable of handling images in a single format
        (e.g. ft_glyph_format_outline). Its functions are used to:

           - transform an glyph image
           - render a glyph image into a bitmap
           - return the control box (dimensions) of a given glyph image


        The scan converters "ftraster.c" and "ftgrays.c" have been moved
        to the new directory "src/renderer", and are used to provide two
        default renderer modules.

        One corresponds to the "standard" scan-converter, the other to the
        "smooth" one.

        The current renderer can be set through the new function
        FT_Set_Renderer.

        The old raster-related function FT_Set_Raster, FT_Get_Raster and
        FT_Set_Raster_Mode have now disappeared, in favor of the new:

           FT_Get_Renderer
           FT_Set_Renderer

        see the file <freetype/ftrender.h> for more details..

        These changes were necessary to properly support different scalable
        formats in the future, like bi-color glyphs, etc..


      - glyph loader object:

        A new internal object, called a 'glyph loader' has been introduced
        in the base layer. It is used by all scalable format font drivers
        to load glyphs and composites.

        This object has been created to reduce the code size of each driver,
        as each one of them basically re-implemented its functionality.

        See <freetype/internal/ftobjs.h> and the FT_GlyphLoader type for
        more information..



      - FT_GlyphSlot had new fields:

        In order to support extended features (see below), the FT_GlyphSlot
        structure has a few new fields:

           linearHoriAdvance:  this field gives the linearly scaled (i.e.
                               scaled but unhinted) advance width for the glyph,
                               expressed as a 16.16 fixed pixel value. This
                               is useful to perform WYSIWYG text.

           linearVertAdvance:  this field gives the linearly scaled advance
                               height for the glyph (relevant in vertical glyph
                               layouts only). This is useful to perform
                               WYSIWYG text.

        Note that the two above field replace the removed "metrics2" field
        in the glyph slot.

           advance:   this field is a vector that gives the transformed
                      advance for the glyph. By default, it corresponds
                      to the advance width, unless FT_LOAD_VERTICAL_LAYOUT
                      was specified when calling FT_Load_Glyph or FT_Load_Char

           bitmap_left: this field gives the distance in integer pixels from
                        the current pen position to the left-most pixel of
                        a glyph image WHEN IT IS A BITMAP. It is only valid
                        when the "format" field is set to
                        "ft_glyph_format_bitmap", for example, after calling
                        the new function FT_Render_Glyph.

           bitmap_top:  this field gives the distance in integer pixels from
                        the current pen position (located on the baseline) to
                        the top-most pixel of the glyph image WHEN IT IS A
                        BITMAP. Positive values correspond to upwards Y.

           loader:  this is a new private field for the glyph slot. Client
                    applications should not touch it..


      - support for transforms and direct rendering in FT_Load_Glyph:

        Most of the functionality found in <freetype/ftglyph.h> has been
        moved to the core library. Hence, the following:

          - a transform can be specified for a face through FT_Set_Transform.
            this transform is applied by FT_Load_Glyph to scalable glyph images
            (i.e. NOT TO BITMAPS) before the function returns, unless the
            bit flag FT_LOAD_IGNORE_TRANSFORM was set in the load flags..


          - once a glyph image has been loaded, it can be directly converted to
            a bitmap by using the new FT_Render_Glyph function. Note that this
            function takes the glyph image from the glyph slot, and converts
            it to a bitmap whose properties are returned in "face.glyph.bitmap",
            "face.glyph.bitmap_left" and "face.glyph.bitmap_top". The original
            native image might be lost after the conversion.


          - when using the new bit flag FT_LOAD_RENDER, the FT_Load_Glyph
            and FT_Load_Char functions will call FT_Render_Glyph automatically
            when needed.

Werner Lemberg 9ca2af3838 A new formatting orgy.
Added some `#if 0' to completely disable the CID AFM stuff.  In case this is
not correct please fix.
2000-06-21 03:03:28 +00:00
David Turner f9b8dec437 major reformatting of the modules source code in order to get
rid of most of the basic types redefinitions (i.e. FT_Int instead
of "FT_Int", etc..)

The format-specific prefixs like "TT_", "T1_", "T2_" & 'CID_"
are now only used in relevant structures..

fixed Werner's fix to t2gload.c :-)
other small bug fixes
2000-06-16 19:34:52 +00:00
Werner Lemberg 7a4fda8821 The next round of formatting, checking documentation, etc. 2000-06-13 23:21:00 +00:00
Werner Lemberg 78575dc0d1 A lot of formatting.
Added more tracing levels.

More Makefile fixes.

Minor other changes.

Werner Lemberg e35cac66c6 A complete revision of FreeType 2's GNU makefiles (of the library):
Tons of unnecessary stuff have been removed; only the essential rules
  have been retained.

  The source files now depend on all header files in include/freetype,
  include/freetype/config, and include/freetype/internal.  This is not
  optimal, I know, and I'll try to improve this, but it is better than
  before (namely no dependencies on `internal').

  FTDEBUG_SRC has been added (similar to FTSYS_SRC) -- I don't know
  exactly whether this is really useful, but it doesn't harm.

  There is now more documentation in the makefiles itself.

io-frames.html: Use of <th>, <code>, and <var> for better tagging.

Reactivating of FT_DEBUG_LEVEL_xxx macros.

Added a lot of #include directives to make `multi' builds possible -- note
that currently the modules cid, t1, and t1z have clashing structures and
functions which means that you can only use one of these three modules for a
multi build.

Added some missing function declarations to (local) header files.

Renamed some T1_Open_Face() to CID_Open_Face() in the cid module -- a lot
of other functions should be renamed also...

Replaced many FT_xxx stuff with T1_xxx in t1z driver -- this isn't finished
yet...

Fixed FT_Free() to allow a NULL pointer without an assertion (this has
always been a valid assumption in FreeType, at least in FT 1.x).

A lot of other, minor fixes (mostly documentation).

David Turner b770a4ab6d bug fix, suggested by Tor Lillqvist 2000-06-07 20:06:18 +00:00
Werner Lemberg e1d5dd78f4 Moved all *errors.h header files to include/freetype/internal for
consistency.

Removed unused error message.
2000-06-07 04:48:12 +00:00
Werner Lemberg 61bd4b9dd1 Added FT_FRAME_SKIP_xxx to skip fields.
More use of READ_Fields() in ttsbit.c

Other minor fixes.
2000-06-07 00:00:08 +00:00
Werner Lemberg 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
