David Turner e13391333f Make macros for header file names optional.
We no longer have to take care of the 8.3 file name limit; this
allows us (a) to introduce longer, meaningful file names, and (b) to
avoid macro names in `#include' lines altogether since some
compilers (most notably Visual C++) doesn't support this properly.

*/*: Replace

   #include FOO_H

with

   #include <freetype/foo.h>

or something similar.  Also update the documentation.

Werner Lemberg 9ac9060df0 [GSoC] src/*.*: Convert block comments to `light' style.
This monster commit was created by applying Nikhil's scripts
`docconverter.py' and `markify.py' to all C header and source files,
followed up by minor manual clean-up.

No change in functionality, of course.

I used commit f7419907bc6044b9b7057f9789866426c804ba82 from
https://github.com/nikramakrishnan/freetype-docs.git.

Werner Lemberg f34f192535 * src/*: Add checks for parameters of API functions where missing.
`API functions' are functions tagged with `FT_EXPORT_DEF'.

Besides trivial fixes, the following changes are included, too.

* src/base/ftbdf.c (FT_Get_BDF_Charset_ID, FT_Get_BDF_Property): Set
error code if no service is available.

* src/base/ftinit.c (FT_Done_FreeType): Change return value for
invalid `library' parameter to `Invalid_Library_Handle'.

* src/base/ftobjs.c (FT_New_Size): Change return value for invalid
`asize' parameter to `Invalid_Argument'.

* src/base/ftoutln.c (FT_Outline_Copy): Change return value for
invalid `source' and `target' parameters to `Invalid_Outline'.
(FT_Outline_Done_Internal): Change return value for invalid
`outline' parameter to `Invalid_Outline'.
2014-11-26 21:59:21 +01:00
Werner Lemberg b24e8ba28a [Savannah bug #43682] Add/remove `void' casts to some functions.
We use a cast to indicate that we intentionally ignore a function's
return value.  However, this doesn't apply to API functions where
errors can only happen for trivially invalid input.

* src/base/ftstroke.c (FT_Glyph_Stroke, FT_Glyph_StrokeBorder),
src/base/ftsynth.c (FT_GlyphSlot_Embolden), src/cff/cffgload.c
(cff_slot_load), src/pfr/pfrdrivr.c (pfr_get_kerning),
src/type1/t1load.c (parse_encoding), src/type42/t42parse.c
(t42_parse_encoding): Do it.

Behdad Esfahbod 31e726d939 Fix vertical size of emboldened glyphs.
Cf. https://bugzilla.gnome.org/show_bug.cgi?id=686709

* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Adjust `horiBearingY'
also.
2013-09-20 07:20:53 +02:00
Werner Lemberg 04affa270b * src/base/ftsynth.c (FT_GlyphSlot_Oblique): Fix shear angle.
The old value was far too large (more than 20°).  The new one
corresponds to 12°, quite common in typography.
2012-08-17 09:28:28 +02:00
Alexei Podtelezhnikov cea9d7a682 * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Improve spacing.

redundant conditional check.
* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Ditto.
* src/cff/cffload.c (cff_encoding_load): Remove conditional check
which always evaluates to `true'.
* src/pshinter/pshalgo.c (ps_glyph_interpolate_strong_points):
Ditto.
* src/truetype/ttinterp.c (Ins_IUP): Ditto.
* src/cid/cidgload.c (cid_slot_load_glyph): Don't check for NULL if
value is already dereferenced.

Werner Lemberg cfc514ea7e * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Don't use internal
macros so that copying the source code into an application works
out of the box.
2008-12-17 11:03:26 +00:00
Werner Lemberg c8c4cc837c * include/freetype/ftsynth.h, src/basae/ftsynth.c: Move

Wu, Chia-I (吳佳一) 032646139d * include/freetype/ftbitmap.h (FT_Bitmap_Embolden): Update
documentation.

* include/freetype/ftsynth.h (FT_GlyphSlot_Own_Bitmap),
src/base/ftsynth.c (FT_GlyphSlot_Own_Bitmap): New function to make
sure a glyph slot owns its bitmap.  It is also marked experimental and
due to change.
(FT_GlyphSlot_Embolden): Undo the last change.  It turns out rendering
the outline confuses some applications.

Wu, Chia-I (吳佳一) 890f807a7b * include/freetype/ftoutln.h (enum FT_Orientation): New value
`FT_ORIENTATION_NONE'.

* src/base/ftoutln.c (FT_OUTLINE_GET_CONTOUR, ft_contour_has,
ft_contour_enclosed, ft_outline_get_orientation): Another version of
`FT_Outline_Get_Orientation'.  This version differs from the public
one in that each part (contour not enclosed in another contour) of the
outline is checked for orientation.
(FT_Outline_Embolden): Use `ft_outline_get_orientation'.

* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Render the outline and
use bitmap's embolden routine when the outline one failed.

Wu, Chia-I (吳佳一) 8cfb220eb9 * include/freetype/internal/ftobjs.h, src/base/ftobjs.c: New function
ft_glyphslot_grid_fit_metrics.

* src/truetype/ttgload.c (compute_glyph_metrics): Use
ft_glyphslot_grid_fit_metrics.

* src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c
(cid_slot_load_glyph), src/type1/t1gload.c (T1_Load_Glyph): Use
ft_glyphslot_grid_fit_metrics.
FT_Outline_Get_CBox is called twice.

* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Modify metrics to more
reasonable values when emboldening outline glyphs.  The theoretic
ones are unrealistic.
2005-06-20 09:04:50 +00:00
Werner Lemberg 49f4d34ed3 * src/base/ftoutln.c (FT_Outline_Embolden): Strength should be
halved.

* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Change the default
strength.
Don't increase slot->advance.y.



* include/freetype/freetype.h (FREETYPE_MINOR): Set to 2.
(FREETYPE_PATCH): Set to 0.

* builds/unix/configure.ac (version_info): Set to 9:9:3.
Currently, we are still binary compatible.

* builds/win32/visualc/index.html,
builds/win32/visualc/freetype.dsp,
builds/win32/visualc/freetype.vcproj: s/219/2110/, s/2.1.9/2.1.10/.

* builds/freetype.mk (refdoc), README, Jamfile (RefDoc):
s/2.1.9/2.1.10/.

* docs/CHANGES, docs/VERSION.DLL: Updated.

* ChangeLog: Split off older entries into...
* ChangeLog.20, ChangeLog.21: These new files.



The next release will be 2.2.0, so don't worry about source code
backwards compatibility.

* include/freetype/ftimage.h (FT_Outline_MoveToFunc,
FT_Outline_LineToFunc, FT_Outline_ConicToFunc,
FT_Outline_CubicToFunc, FT_SpanFunc, FT_Raster_RenderFunc),
include/freetype/ftrender.h (FT_Glyph_TransformFunc,
FT_Renderer_RenderFunc, FT_Renderer_TransformFunc): Decorate
parameters with `const' where appropriate.



* src/sfnt/ttsbit.c (tt_face_load_sbit_image): Compute vertBearingY
to make glyphs centered vertically.

* src/truetype/ttgload.c (compute_glyph_metrics): Compute
vertBearingY to make glyphs centered vertically.
Fix some bugs in vertical metrics:

  . loader->pp3.y and loader->pp4.y are in 26.6 format, not in font
    units.
  . As we use the glyph's cbox to calculate the top bearing now
    there iss no need to adjust `top'.



* src/otvalid/otvcommn.h (OTV_OPTIONAL_TABLE): Use FT_UShort to be
in sync with OTV_OPTIONAL_OFFSET.  Reported by YAMATO Masatake.


* docs/release: Update.
2005-06-16 19:07:08 +00:00
Werner Lemberg 71d7628175 * src/base/ftbitmap.c (FT_Bitmap_Embolden): Fix emboldening bitmap
of mode FT_PIXEL_MODE_GRAY.  Also add support for mode
FT_PIXEL_MODE_LCD and FT_PIXEL_MODE_LCD_V.
(ft_bitmap_assure_buffer): FT_PIXEL_MODE_LCD and FT_PIXEL_MODE_LCD_V
should have ppb (pixel per byte) 1.
Zero the padding when there's no need to allocate memory.

* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Handle slot->advance
too.
More suited emboldening strength.
2005-05-30 07:54:20 +00:00
Werner Lemberg 3a36ef7e6e * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Initialize `error'. 2005-05-27 04:18:20 +00:00

Werner Lemberg c8c6bf5c63 Cleanups; adding some copyrights; formatting. 2003-04-23 05:38:13 +00:00
David Turner 3249c62523 * include/freetype/internal/internal.h, include/freetype/ftpfr.h,

        src/pfr/pfrdrivr.c, src/pfr/pfrobjs.c, src/pfr/pfsobjs.h:

        added PFR-specific public API. Fixed the kerning retrievel routine
        (it returned invalid values when the outline and metrics resolution
        differ)

        * src/base/ftsynth.c: fixed the synthetic emboldener. at last.

        * src/base/ftobjs.c: small internal fix to better support
        bitmap-based font formats
2002-10-31 08:30:19 +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_.
