David Turner c13e75fb1b * src/base/ftutil.c: ft_mem_alloc and related functions now return an
error if a negative size is passed in parameters.

    * src/cache/ftccache.c: make ftc_node_destroy FT_BASE_DEF, it needs to
    be exported for rogue clients

    * src/pshinter/pshglob.c: prevent problems with malformed fonts which
    have an odd number of blue values (these are broken according to the
    specs).

    * src/cff/cffload.c, src/type1/t1load.c: modify the loaders to force
    even-ness of 'num_blue_values'. Also change the CFF loader so that
    invalid entries in index files are ignored.

Werner Lemberg 59939244ad Implement new, simplified module selection. With GNU make it is now
sufficient to modify a single file, `modules.cfg', to control the
inclusion of modules and base extension files.

This change also fixes the creation of ftmodule.h; it now depends on
`modules.cfg' and thus is rebuilt only if necessary.

Finally, a version of `ftoption.h' in OBJ_DIR is preferred over the
default location.

* modules.cfg: New file.

* builds/freetype.mk: Don't include `modules.mk'.
Include all `rules.mk' files as specified in `modules.cfg'.
(FTOPTION_FLAG, FTOPTION_H): New variables.
(FT_CFLAGS): Add macro definition for FT_CONFIG_MODULES_H.
Add FTOPTION_FLAG.
($(FT_INIT_OBJ)): Don't use FT_MODULE_LIST.
(CONFIG_H): Add FTMODULE_H and FTOPTION_H.
(INCLUDES): Add DEVEL_DIR.
(INCLUDE_FLAGS, FTSYS_SRC, FTSYS_OBJ, FTDEBUG_SRC, FTDEBUG_OBJ,
OBJ_M, OBJ_S): Use `:=', not `='.
(remove_ftmodule_h): New phony target to delete `ftmodule.h'.
(distclean): Add remove_ftmodule_h.

* builds/modules.mk: (MODULE_LIST): Removed.
(make_module_list, clean_module_list): Replace targets
with...
(FTMODULE_H_INIT, FTMODULE_H_CREATE, FTMODULE_H_DONE): New
variables.  Reason for the change is that it is not possible to have
a phony prerequisite which is run only if the target file must be
rebuilt (phony prerequisites act like subroutines and are *always*
executed).  We only want to rebuild `ftmodule.h' if `module.cfg' is
changed.
Update all callers.
($FTMODULE_H)): Rule to create `ftmodule.h', depending on
`modules.cfg'.

* builds/toplevel.mk: Rewrite and simplify module handling.
(MODULES_CFG, FTMODULE_H): New variables.
Include MODULES_CFG.
(MODULES): New variable to include all `module.mk' and `rules.mk'
files.  We no longer use make's `wildcard' function for this.

* Makefile (USE_MODULES): Remove.  Update all users.
(OBJ_DIR): Define it here.

* src/*/module.mk: Change

    make_module_list: foo
    foo: ...

to

    FTMODULE_H_COMMANDS += FOO
    define FOO
    ...
    endef

in all files.  `FTMODULE_H_COMMANDS' is used in `FTMODULE_H_CREATE'.

* src/base/rules.mk (BASE_EXT_SRC): Use BASE_EXTENSIONS.

* builds/unix/detect.mk (setup): Always execute `configure' script.
(have_mk): Rename to...
(have_Makefile): This.
Don't use `strip' function.

* builds/unix/unix.mk: Include `install.mk' only if BUILD_PROJECT is
defined.
(have_mk): Don't use `strip' function.
Test for unix-def.mk in OBJ_DIR, not BUILD_DIR (and invert the test
accordingly).

* builds/unix/install.mk (install, uninstall): Handle `ftmodule.h'.

* builds/os2/os2-dev.mk, builds/unix/unix-dev.mk,
builds/win32/w32-bccd.mk, builds/win32/w32-dev.mk: Don't define
BUILD_DIR but DEVEL_DIR for development header files.

* builds/ansi/ansi-def.mk (TOP_DIR, OBJ_DIR),
builds/beos/beos-def.mk (TOP_DIR, OBJ_DIR), builds/unix/unix-def.in
(TOP_DIR, OBJ_DIR): Removed.  Defined elsewhere.

* builds/dos/dos-def.mk (OBJ_DIR), builds/os2/os2-def.mk (OBJ_DIR),
builds/win32/win32-def.mk (OBJ_DIR): Removed.  Defined elsewhere.

* builds/unix/unixddef.mk: Don't define BUILD_DIR but DEVEL_DIR for
development header files.
Don't define PLATFORM.

* configure: Copy `modules.cfg' to builddir if builddir != srcdir.
Update snippet taken from autoconf's m4sh.m4 to current CVS version.
Be more verbose.

* include/freetype/config/ftmodule.h: Add comments -- this file is
no longer used if FreeType is built with GNU make.

* docs/CHANGES, docs/CUSTOMIZE, docs/INSTALL, docs/INSTALL.ANY,
docs/INSTALL.GNU, docs/INSTALL.UNX: Document new build mechanism.
Other minor updates.

* modules.txt: Removed.  Contents included in `modules.cfg'.


* include/freetype/internal/ftmemory.h (FT_QAlloc_Debug,
FT_Free_Debug) [FT_STRICT_ALIASING]: Fix typos.

* src/base/ftdbgmem.c (FT_Alloc_Debug, FT_Realloc_Debug,
FT_QAlloc_Debug, FT_QRealloc_Debug, FT_Free_Debug)
[FT_STRICT_ALIASING]: Implement.

Werner Lemberg 675431bec1 * include/freetype/t1tables.h (PS_PrivateRec): Add
`expansion_factor'.

* src/pshinter/pshglob (psh_blues_scale_zones): Fix computation
of blues->no_overshoots -- `blues_scale' is stored with a
magnification of 1000, and `scale' returns fractional pixels.

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'.

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/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'.

Werner Lemberg bb3105e256 Cleanups. 2003-04-23 15:17:43 +00:00
David Turner 5158fbc03d * README: udpated
* README.UNX: removed (now replaced by docs/INSTALL.UNX)

   * src/pshinter/pshalgo3.c: the hinter now performs as in 2.1.3 and
   will ignore stem quantization only when FT_LOAD_TARGET_SMOOTH is used

   * src/base/ftobjs.c: changed the default computations to include rounding
   in all cases, this is required to provide accurate kerning data when
   native TrueType hinting is enabled.

   * src/type1/t1load.c: the Type 1 loader now accepts more general names
   according to the Postscript spec (the previous one was too restrictive)
2003-03-27 21:35:44 +00:00
David Turner 4bdf4350f2 various improvements for 2.1.4. see ChangeLog, I've got problems with
copy & paste on my desktop !!
2003-01-30 23:24:18 +00:00
David Turner 032e23aab9 improvements to the Postscript hinter 2003-01-30 14:57:38 +00:00
David Turner 265799a933 * src/autohint/ahtypes.h, src/autohint/ahhint.c, src/pshinter/pshalgo3.h,
src/pshinter/pshalgo3.c: implemented the FT_RENDER_MODE_LIGHT hinting
        mode in the auto and postscript hinters
2003-01-08 09:52:32 +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
2002-11-06 22:32:54 +00:00
Werner Lemberg 7a99b507ce * src/type1/t1parse.h (T1_ParserRec): Change type of `base_len'
and `private_len' to FT_Long.

* src/cache/ftcsbits.c (ftc_sbit_node_load): Remove unused label.
* src/pshinter/pshalgo3.c (psh3_hint_align): Remove unused variable.
2002-09-17 07:31:17 +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 !
2002-09-09 23:45:29 +00:00
David Turner 00d9f40cf7 * src/smooth/ftsmooth.c, src/base/ftobjs.c,
include/freetype/config/ftmodule.h: updated to correctly support
        sub-pixel rendering

        * include/freetype/cache/ftcimage.h, include/freetype/cache/ftcsbits.h,
        src/cache/ftcimage.c, src/cache/ftcsbit.c: updated to support sub-pixel
        rendering correctly. Definition of FTC_ImageTypeRec that replaces the
        obsolete FTC_ImageDesc, and has slightly different fields. The
        image type is now determined directly by "load_flags" values.

        * src/autohint/ahtypes.h, src/autohint/ahhint.c,
        src/pshinter/pshalgo3.c, src/pshinter/pshalgo3.h: various enhancements
        to the automatic and Postscript hinters !! and sub-pixel hinting now
        works correctly (see demo programs)
2002-09-08 21:29:11 +00:00
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.
2002-09-05 15:10:54 +00:00
David Turner d53bfeb810 * src/pshinter/pshalgo.c: slight modification to the Postscript hinter
to slightly increase the contrast of smooth hinting. This is very similar
    to what the auto-hinter does when it comes to stem width computations.
    However, it produces better results with well-hinted fonts..
2002-08-29 22:50:17 +00:00
David Turner d1245c0dd2 updating sources to support the new FT_LOAD_TARGET_ constants
to support target-specific hinting
2002-08-27 22:34:20 +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_.

Werner Lemberg ec810f8c6a * src/pshinter/pshalgo3.c (psh3_glyph_compute_inflections,
psh3_glyph_compute_extrema, psh3_hint_table_find_strong_point): Fix
compiler warnings and resolve shadowing of local variables.
