c2cd00443b minor optimisations in ftcalc.c 2001-04-26 00:21:48 +00:00
David Turner
ec46b28df7 * src/base/ftcalc.c (FT_SqrtFixed): corrected/optimised the 32-bit
fixed-point square root. it is now used even with 64-bits
	ints, as it's simply _much_ faster than calling FT_Sqrt64 :-)

    * src/base/ftbbox.c : removed invalid "#include FT_BEZIER_H" line
2001-04-25 22:56:30 +00:00
David Turner
caf72cd6e5 * src/base/ftbbox.c (BBox_Cubic_Check): rewrote function to use
direct computations with 16.16 values instead of sub-divisions.
        It is now slower, but proves a point :-)

        * src/raster/ftraster.c, src/smooth/ftgrays.c, src/base/ftbbox.c :
        fixed the bezier stack depths..

        * src/base/ftcalc.c (FT_MulFix): minor rounding fix

        * builds/beos : added BeOS-specific files to the old build system
        (no changes were necessary to support BeOS in the Jamfile though)

6d4fbec1b8 * ftconfig.h, ftoption.h: updated "ftconfig.h" to detect 64-bit int
types on platforms where Autoconf is not available). Also removed
	FTCALC_USE_LONG_LONG and replaced it with FT_CONFIG_OPTION_FORCE_INT64

	* builds/win32/freetype.dsp: updated the Visual C++ project file. Doesn't
	create a DLL yet..

	* cffgload.c: removed a compilation warning

rounding errors when placing this real number into a 16.16 fixed
number).

In function cff_parse_real, added code so that the integer part is

dictionaries to be parsed by the Type 1 driver.

fonts with no subroutines still are parsed.

594f0c965d * *.mk: Added lots of `.PHONY' targets.
* *.mk: Implemented `platform' target to disable auto-detection.


Added support for clipped direct rendering in the smooth renderer.
This should not break binary compatibility of existing applications.
* include/freetype/fttypes.h, include/freetype/ftimage.h: Move
definition of the FT_BBox structure from the former to the latter.
* include/freetype/ftimage.h: Add `ft_raster_flag_clip' value to
FT_Raster_Flag enumeration.
Add `clip_box' element to FT_Raster_Params structure.
* src/smooth/ftgrays.c (grays_convert_glyph): Implement it.

* src/raster/ftraster.c (ft_black_render): Test for unsupported
direct rendering before testing arguments.

compiler, as well as _preliminary_ (read: doesn't work!) support for
Watcom.  Also added a new setup target.  Type "make setup list" for
a list of supported command-line compilers on Win32.

* src/psaux/psauxmod.c: Fixed a broken inclusion of component
header files (an FT_FLAT_COMPILE test was missing).
* src/cache/ftcmanag.c (FTC_Manager_Done): Fixed a bug that caused
an occasional crash when the function was called (due to a dangling
pointer).
* src/base/ftsystem.c (FT_Done_Memory): Fixed an obvious bug:
The ANSI "free()" function was called instead of "memory->free()".
* docs/docmaker.py: Added section filtering, multi-page generation
(index page generation is still missing though).
* builds/unix/install.mk, builds/unix/ft2unix.h: The file "ft2unix.h"
is now installed as <ft2build.h> for Unix systems.  Note that we
still use the "freetype2/freetype" installation path for now.

* many files: Now using <ft2build.h> as the default build and setup
configuration file in all public headers.  Internal source files
still need some changes though.
* builds/devel/ft2build.h, builds/devel/ftoption.h: Created a new
Win32 developer builds.
builds/win32/w32-dev.mk: Changed the developer build targets to
"devel-gcc" and "devel-bcc" in order to be able to develop with the
Borland C++ compiler.

  - 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

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..

   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

40822003da In function parse_encoding, initialize encoding_table.elements to have
.notdef in each entry.

In function parse_charstrings, place the .notdef glyph in index 0, and
add a .notdef glyph if it is missing.

In function Z1_Open_Face, only change min/max encoded char if it is not
.notdef.

4e38576a97 fixed a bug that happened when rendering spaces
in monochrome mode..

actually, when outline.num_points == 0, it is legal
to have outline.points == 0 too. The code did return
a FT_Err_Invalid_Outline error incorrectly then because
the checks were not performed in the correct order

a8194a97db - added a new function called FT_SqrtFixed to compute the
16.16 square root of a 16.16 number (this could come handy
  in a later version of the auto-hinter)

- small fixes to the smooth renderer. It used to use way too
  much line segments when drawing beziers !!

(note that the "ftview" program has been changed to
use the caching sub-system, "ftmulti" and "ftstring"
should come soon).

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).
