Behdad Esfahbod 760d342d37 Add support for color embedded bitmaps (eg. color emoji).
A new load flag, FT_LOAD_COLOR, makes FreeType load color
embedded-bitmaps, following this draft specification

  https://color-emoji.googlecode.com/git/specification/v1.html

which defines two new SFNT tables, `CBDT' and `CBLC' (named and
modeled after `EBDT' and `EBLC', respectively).  The color bitmaps
are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA
pre-multiplied sRGB images.  If PNG support is available, PNG color
images as defined in the same proposed specification are supported
also.

Note that color bitmaps are converted to grayscale if client didn't
ask for color.

Werner Lemberg 7227114043 Fix B/W rasterization of subglyphs with different drop-out modes.
Normally, the SCANMODE instruction (if present) to set the drop-out
mode in a TrueType font is located in the `prep' table only and thus
valid for all glyphs.  However, there are fonts like `pala.ttf'
which additionally contain this instruction in the hinting code of
some glyphs (but not all).  As a result it can happen that a
composite glyph needs multiple drop-out modes for its subglyphs
since the rendering state gets reset for each subglyph.

FreeType collects the hinted outlines from all subglyphs, then it
sends the data to the rasterizer.  It also sends the drop-out mode
-- after hinting has been applied -- and here is the error: It sends
the drop-out mode of the last subglyph only; drop-out modes of all
other subglyphs are lost.

This patch fixes the problem; it adds a second, alternative
mechanism to pass the drop-out mode: For each contour, the
rasterizer now checks the first `tags' array element.  If bit 2 is
set, bits 5-7 contain the contour's drop-out mode, overriding the
global drop-out mode.

* include/freetype/ftimage.h (FT_CURVE_TAG_HAS_SCANMODE): New macro.

* src/truetype/ttgload.c (TT_Hint_Glyph): Store drop-out mode in
`tags[0]'.

* src/raster/ftraster.c (Flow_Up, Overshoot_Top, Overshoot_Bottom):
Use bits 3-5 instead of 0-2.
(New_Profile): Set the drop-out mode in the profile's `flags' field.
(Decompose_Curve): Check `tags[0]' and set `dropOutControl' if
necessary.
(Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
Horizontal_Gray_Sweep_Drop, Draw_Sweep): Use the profile's drop-out
mode.

Werner Lemberg e42dbcec21 * Version 2.1.7 released.
=========================


* builds/unix/ft2unix.h: Fix comments.

* builds/unix/ftconfig.in: Synchronized with ANSI version.
Use `#undef' in templates as recommended in the autoconf
documentation.
Since real `#undef' lines don't survive during configuration, use
`/undef' instead; the postprocessing facility of the
AC_CONFIG_HEADERS autoconf macro converts them to `#undef'.

* builds/unix/install.mk (install): Install Unix version of
`ftconfig.h'.

* builds/unix/unix-cc.in (CFLAGS): Set FT_CONFIG_CONFIG_H macro
to include the correct `ftconfig.h' file.

* builds/unix/ft-munmap.m4 (FT_MUNMAP_DECL): Removed.
(FT_MUNMAP_PARAM): Updated syntax to autoconf 2.59.

* builds/unix/freetype2.m4: Updated syntax to autoconf 2.59.

* builds/unix/configure.ac: Use AC_CONFIG_HEADERS instead of
AC_CONFIG_HEADER to create ftconfig.h, and use second argument
to replace `/undef' with `#undef'.
Don't use FT_MUNMAP_DECL but AC_CHECK_DECLS to check for munmap.
Use AS_HELP_STRING in AC_ARG_WITH.
Update syntax to autoconf 2.59.

* builds/unix/ltmain.sh: Regenerated with `libtoolize --force
--copy' from libtool 1.5.
* builds/unix/aclocal.m4: Regenerated with `aclocal -I .' from
automake 1.7.8.
* builds/unix/configure: Regenerated with autoconf 2.59.

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.
2003-07-01 07:28:55 +00:00
Werner Lemberg 7a0241049a * include/freetype/freetype.h (FT_Open_Flags): Replaced with

(FT_GlyphSlot): Move `flags' to FT_Slot_Internal.

* include/freetype/ftimage.h (FT_Outline_Flags, FT_Raster_Flag):
Replaced with #defines for the constants.

* include/freetype/internal/ftobjs.h (FT_Slot_Internal): New
field `flags' (from FT_GlyphSlot).
Updated all affected source files.
(FT_GLYPH_OWN_BITMAP): New macro (from ftgloadr.h).

* include/freetype/internal/ftgloadr.h (FT_GLYPH_OWN_BITMAP): Moved
to ftobjs.h.

* src/base/ftglyph.c (FT_Glyph_To_Bitmap): Use dummy
FT_GlyphSlot_Internal object.

FT_BEGIN_HEADER, FT_END_HEADER.
(FT_MEM_ZERO): Define.
(TRaster) [GRAYS_USE_GAMMA]: Use `unsigned char' instead of FT_Byte.
(gray_render_span, gray_init_gamma): Don't use `FT_UInt'.
Don't cast with `FT_Byte'.
(grays_init_gamma): Don't use `FT_UInt'.

* src/base/ftinit.c (FT_Add_Default_Modules): Improve error message.

David Turner bb076bd0fb cosmetic + typo fixes 2002-09-11 06:13:09 +00:00
David Turner 25f845aa64 * src/cache/ftccache.i: fixed a bug that prevented compilation in
debug mode of template instantiation

        * src/cff/cffparse.c: fixed the CFF table loader. It didn't accept
        empty arrays, and this prevented the loading of certain fonts.

        * src/pshinter/pshalgo2.c, src/pshinter/pshalgo3.c: adding fix to
        prevent seg fault when hints are provided in an empty glyph !!

        * include/freetype/ftimage.h: removed incorrect "zft_" definitions
        and updated constants documentation comments

        * include/freetype/freetype.h (FT_FaceRec): updating documentation
        comment. The "descender" value is always *negative*, not positive !

Werner Lemberg 6b5c669b7b * src/cid/cidobjs.c (CID_Size_Init): Renamed to...
(cid_size_init): This.
* src/psaux/psobjs.c (T1_Builder_Add_Point1): Renamed to...
(t1_builder_add_point1): This.

Updated all affected code.

* src/pshinter/pshalgo3.c (psh3_hint_align): Fix compiler warnings.
* src/type1/t1gload.c (T1_Compute_Max_Advance): Ditto.

Formatting, minor doc fixes.

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_.
