Alexei Podtelezhnikov 8fb88414 2011-03-17T20:24:57 A better fix for Savannah bug #32671. * src/smooth/ftgrays.c (gray_render_conic): Clean up code and replace WHILE loop with a more natural DO-WHILE construct.
Werner Lemberg 6c045535 2011-03-07T05:40:42 Quick fix for Savannah bug #32671. This isn't the optimal solution yet, but it restores the previous rendering quality (more or less). * src/smooth/ftgrays.c (gray_render_conic): Do more splitting.
Алексей Подтележников 7c4ac3cb 2010-11-28T08:23:40 [ftsmooth]: Minor code simplification. * src/smooth/ftgrays (gray_render_cubic): Do only one comparison instead of two.
Alexei Podtelezhnikov 6aee6909 2010-11-02T16:01:03 [ftsmooth] Improve rendering. * src/smooth/ftsmooth.c (gray_render_conic): Since version 2.4.3, cubic deviations have been estimated _after_ UPSCALE, whereas conic ones have been evaluated _before_ UPSCALE, which produces inferior rendering results. Fix this. Partially undo change from 2010-10-15 by using ONE_PIXEL/4; this has been tested with demo images sent to the mailing list. See http://lists.gnu.org/archive/html/freetype-devel/2010-10/msg00055.html and later mails in this thread.
Werner Lemberg 34d61e86 2010-10-15T20:44:15 Fix thinko in spline flattening. FT_MAX_CURVE_DEVIATION is dependent on the value of ONE_PIXEL. * src/smooth/ftgrays.c (FT_MAX_CURVE_DEVIATION): Remove it and replace it everywhere with ONE_PIXEL/8.
Werner Lemberg 0e6fc091 2010-10-02T09:05:46 [smooth] Fix splitting of cubics for negative values. Reported by Róbert Márki <gsmiko@gmail.com>; see http://lists.gnu.org/archive/html/freetype/2010-09/msg00019.html. * src/smooth/ftgrays.c (gray_render_cubic): Fix thinko.
Graham Asher e0a9a933 2010-09-20T09:29:23 [smooth] Fix and improve spline flattening. This fixes the flattening of cubic, S-shaped curves and speeds up the handling of both the conic and cubic arcs. See the discussions on the freetype-devel mailing list in late August and September 2010 for details. * src/smooth/ftgrays.c (FT_MAX_CURVE_DEVIATION): New macro. (TWorker): Remove `conic_level' and `cubic_level' elements. (gray_render_conic): Simplify algorithm. (gray_render_cubic): New algorithm; details are given in the code comments. (gray_convert_glyph): Remove heuristics.
Werner Lemberg c8f5b98b 2010-07-12T21:13:22 Remove C++ warnings. */*: Initialize pointers where necessary to make g++ happy.
Werner Lemberg e0176397 2010-07-03T15:31:38 Make ftgrays.c compile stand-alone again. * src/smooth/ftgrays.c [_STANDALONE_]: Include `stddef.h'. (FT_INT_MAX, FT_PtrDist)[_STANDALONE_]: Define.
Werner Lemberg 6305b869 2010-06-30T18:24:33 Fix Savannah bug #30263. * src/smooth/ftgrays.c (gray_render_span): Use cast to `unsigned int' to avoid integer overflow. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Use smaller threshold values for `width' and `height'. This is not directly related to the bug fix but makes sense anyway.
Graham Asher e419f48b 2010-06-24T12:50:46 * src/smooth/ftgrays.c (gray_render_cubic): Fix algorithm. The previous version was too aggressive, as demonstrated in http://lists.gnu.org/archive/html/freetype-devel/2010-06/msg00020.html.
Graham Asher 7fb3ef64 2010-06-10T08:10:57 ftgrays: Speed up rendering of small cubic splines. * src/smooth/ftgrays.c (gray_render_cubic): Implement new, simplified algorithm to find out whether the spline can be replaced with two straight lines. See this thread for more: http://lists.gnu.org/archive/html/freetype-devel/2010-06/msg00000.html
Werner Lemberg ad61f178 2010-06-09T15:18:57 Oops, revert unwanted previous commit for ftgrays.c.
Werner Lemberg 7d3d2cc4 2010-06-09T09:14:09 Fix Savannah bug #30082. * src/cff/cffgload.c (cff_decoder_parse_charstrings) <cff_op_callothersubr>: Protect against stack underflow.

(ras): Define/declare after definition of `TWorker'. Use `RAS_VAR_' where necessary.
Oran Agra c1e22f39 2009-04-05T18:14:04 Position Independent Code (PIC) support in smooth renderer. * src/smooth/ftsmooth.h declare ft_smooth_renderer_class, ft_smooth_lcd_renderer_class and ft_smooth_lcd_v_renderer_class using macros from ftrender.h, when FT_CONFIG_OPTION_PIC is defined create and destroy functions will be declared. * src/smooth/ftsmooth.c when FT_CONFIG_OPTION_PIC is defined the following structs: ft_smooth_renderer_class, ft_smooth_lcd_renderer_class and ft_smooth_lcd_v_renderer_class will have functions to init or create and destroy them instead of being allocated in the global scope. And macros will be used from ftspic.h in order to access ft_grays_raster from the pic_container (allocated in ftgrays.c). * src/smooth/ftgrays.h include FT_CONFIG_CONFIG_H * src/smooth/ftgrays.c when FT_CONFIG_OPTION_PIC is NOT defined func_interface was moved from gray_convert_glyph_inner function to the global scope. When FT_CONFIG_OPTION_PIC is defined func_interface and ft_grays_raster structs will have functions to init them instead of being allocated in the global scope. And func_interface will be allocated on the stack of gray_convert_glyph_inner. New Files: * src/smooth/ftspic.h declare struct to hold PIC globals for smooth renderer and macros to access them. * src/smooth/ftspic.c implement functions to allocate, destroy and initialize PIC globals for smooth renderer. * src/smooth/smooth.c add new file to build: ftspic.c. * src/smooth/jamfile add new files to FT2_MULTI build: ftspic.c.

David Turner b08fe2dc 2002-08-27T20:20:29 * 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_.

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.
Werner Lemberg 9ca7a157 2002-04-30T14:26:49 * src/base/ftmac.c (p2c_str): Removed. (file_spec_from_path) [TARGET_API_MAC_CARBON]: Added support for OS X. (is_dfont) [TARGET_API_MAC_CARBON]: Define only for OS X. Handle `nameLen' <= 6 also. (parse_fond): Remove unused variable `name_table'. Use functionality of old p2c_str directly. Add safety checks. (read_lwfn): Initialize `size_p'. Check for size_p == NULL. (new_memory_stream, open_face_from_buffer): Updated to FreeType 2.1. (FT_New_Face_From_LWFN): Remove unused variable `memory'. Remove some dead code. (FT_New_Face_From_SFNT): Remove unused variable `stream'. (FT_New_Face_From_dfont) [TARGET_API_MAC_CARBON]: Define only for OS X. (FT_New_Face_From_FOND): Remove unused variable `error'. (ResourceForkSize): New function. (FT_New_Face): Use it. Handle empty resource forks. Conditionalize some code for OS X. Add code to call normal loader as a fallback. Some more variable renames to avoid troubles on the Mac. * src/raster/ftraster.c: s/Unknown|Ascending|Descending|Flat/\1_State/. * src/smooth/ftgrays.c: s/TScan/TCoord/. Other changes for the Mac. * include/freetype/config/ftconfig.h: Define FT_MACINTOSH for Mac platforms. * src/base/ftobjs.c: s/macintosh/FT_MACINTOSH/. * src/raster/ftrend1.c (ft_raster1_render): Make `pitch' always an even number.
Werner Lemberg 5f0ee94c 2002-04-30T06:37:52 `interface' is reserved on the Mac. * include/freetype/ftoutln.h, include/freetype/internal/sfnt.h, src/base/ftoutln.c: s/interface/func_interface/. * src/base/ftbbox.c (FT_Outline_Get_BBox): s/interface/bbox_interface/. * src/cff/cffdrivr.c: s/interface/module_interface/. * src/cff/cffload.c, src/cff/cffload.h: s/interface/psnames_interface/. * src/cid/cidriver.c: s/interface/cid_interface/. * src/sfnt/sfdriver.c: s/interface/module_interface/. * src/smooth/ftgrays.c: s/interface/func_interface/. * src/truetype/ttdriver.c: s/interface/tt_interface/. * src/type1/t1driver.c: s/interface/t1_interface/.
Werner Lemberg 94ffae52 2002-04-14T00:54:32 * src/cff/cffgload.c (CFF_Parse_CharStrings): s/rand/Rand/ to avoid compiler warning. formatting/fixing ChangeLog
David Turner d15bc0d1 2002-04-12T09:31:48 * README.UNX: updated the Unix-specific quick-compilation guide to warn about the GNU Make requirement at compile time.. * include/freetype/config/ftstdlib.h, include/freetype/config/ftconfig.h, include/freetype/config/ftheader.h, include/freetype/internal/ftmemory.h, include/freetype/internal/ftobjs.h, src/autohint/ahoptim.c, src/base/ftdbgmem.c, src/base/ftdebug.c, src/base/ftmac.c, src/base/ftobjs.c, src/base/ftsystem.c, src/cache/ftcimage.c, src/cache/ftcsbits.c, src/cff/cffdriver.c, src/cff/cffload.c, src/cff/cffobjs.c, src/cid/cidload.c, src/cid/cidparse.c, src/cid/cidriver.c, src/pcf/pcfdriver.c, src/pcf/pcfread.c, src/psaux/t1cmap.c, src/psaux/t1decode.c, src/pshinter/pshalgo1.c, src/pshinter/pshalgo2.c, src/pshinter/pshrec.c, src/psnames/psmodule.c, src/raster/ftraster.c, src/sfnt/sfdriver.c, src/sfnt/ttload.c, src/sfnt/ttpost.c, src/smooth/ftgrays.c, src/type1/t1afm.c, src/type1/t1driver.c, src/type1/t1gload.c, src/type1/t1load.c, src/type1/t1objs.c, src/type1/t1parse.c: added the new configuration file "ftstdlib.h" used to define aliases for all ISO C library functions used by the engine (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... from the engine's sources where they're not needed..
David Turner 2c7558ce 2002-04-11T14:21:16 * README, docs/CHANGES, Jamfile.in: updating for the 2.1.0 release
Werner Lemberg 91db04cb 2002-04-01T14:25:28 * src/truetype/ttgload.c: 16bit fixes. (TT_Load_Simple_Glyph): Improve debug messages. (load_truetype_glyph): Remove dead code. * src/truetype/ttinterp.c: 16bit fixes. * src/truetype/ttobjs.c: Ditto. * include/freetype/ftsnames.h, include/freetype/internal/sfnt.h, src/cff/cffload.h, src/psaux/psobjs.h, src/truetype/ttinterp.[ch], src/sfnt/ttpost.h: s/index/idx/. formatting, copyright updates.
David Turner e459d742 2002-03-22T13:52:37 * 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..
David Turner 222cec8c 2002-02-21T11:48:48 * include/freetype/internal/ftdebug.h, src/base/ftdebug.c: modified the debug sub-system initialization. trace levels can now be specified within the "FT2_DEBUG" environment variable. See the comments within "ftdebug.c" for more details * include/freetype/internal/fttrace.h: new file to define the trace levels used for debugging. it is used both to define enums and toggle names for FT2_DEBUG * src/base/ftobjs.c, src/base/ftstream.c: FT_Assert renamed to FT_ASSERT * include/freetype/internal/ftextend.h, src/base/ftextend.c, src/base/Jamfile, src/base/rules.mk: removing "ftextend" from the library, since it is now completely obsolete..
Werner Lemberg e274290d 2002-01-28T05:04:22 * src/smooth/ftgrays.c (gray_render_scanline): Fix bug which caused bad rendering of thin lines (less than one pixel thick).

Werner Lemberg c3b21608 2001-12-05T01:22:05 Formatting. Cleaning up of ChangeLog. * docs/license.txt: s/X Windows/X Window System/. * src/raster/ftraster.c: Fix definition condition of MEM_Set(). * src/smooth/ftgrays.c (M_Y): Change value to 192. * src/base/ftdbgmem.c (ft_mem_table_destroy): Fix printf() parameter. Remove unused variable. * src/cache/ftcimage.c (ftc_image_node_init, ftc_image_node_compare): Remove unused variables. * src/cache/ftcsbits.c (ftc_sbit_node_weight): Remove unused variable. * src/raster/ftraster.c (MEM_Set): Move definition down to avoid compiler warning. * src/autohint/ahhint.c (ah_hinter_hint_edges): Use UNUSED() to avoid compiler warnings. * src/pcf/pcfread.c (tableNames): Use `const'. (pcf_read_TOC): Change counter name to avoid compiler warning. Use `const'. * src/pshinter/pshrec.c (ps_hints_close): Remove redundant declaration. * src/pshinter/pshalgo1.c (psh1_hint_table_init): Rename variables to avoid shadowing. * src/pshinter/pshalgo2.c (psh2_hint_table_activate_mask): Ditto. * src/type1/t1objs.h: Remove double declarations of `T1_Size_Init()' and `T1_Size_Done()'.
David Turner f2c56515 2001-11-20T01:29:34 * src/pshinter/{pshalgo2.c, pshalgo1.c}: fixed stupid bug in sorting routine that created nasty alignment artefacts. * src/pshinter/pshrec.c, tests/gview.c: debugging updates.. * src/smooth/ftgrays.c: de-activated experimental gamme support, apparently, "optimal" gamma tables depend on the monitor type, resolution and general karma, so it's better to compute them outside of the rasterizer itself..
David Turner adf07a93 2001-10-30T23:51:24 * src/smooth/ftgrays.c: adding experimental "gamma" support. This produces smoother glyphs at small sizes for very little cost * src/autohint/ahglyph.c, src/autohint/ahhint.c: various fixes to the auto-hinter. They merely improve the output of sans-serif fonts. Note that there are still problems with serifed fonts and composites (accented characters) * tests/gview.c: updated the debugging glyph viewer to show the hints generated by the "autohint" module
David Turner 5a1de37e 2001-10-24T07:32:55 replaced liberal uses of "memset" by the "MEM_Set" macro call (some platforms don't provide this ANSI function !!) some changes to "ftsystem.c" implementations in order to use the new memory debugger on Unix, VMS and Amiga too !!
David Turner 7e4b52d1 2001-10-19T09:17:49 getting rid of compiler warnings
Werner Lemberg 80b8d770 2001-10-10T19:56:42 Fixed a bug in `glnames.py' that prevented it from generating correct glyph names tables. This resulted in the unavailability of certain glyphs like `Cacute', `cacute' and `lslash' in Unicode charmaps, even if these were present in the font (causing problems for Polish users). * src/tools/glnames.py (mac_standard_names): Fixed. (t1_standard_strings): Some fixes and renamed to ... (sid_standard_names): This. (t1_expert_encoding): Fixed. (the_adobe_glyph_list): Renamed to ... (adobe_glyph_names): This.

Use `sid_standard_table' and `ps_names_to_unicode' instead of `t1_standard_glyphs' and `names_to_unicode'. (PS_Macintosh_Name): Use `ps_glyph_names' instead of `standard_glyph_names'. (PS_Standard_Strings): Use `sid_standard_names' instead of `t1_standard_glyphs'. * doc/BUGS, doc/TODO: New documents. * src/cache/ftlru.c (FT_Lru_Lookup_Node): Fixed a bug that prevented correct LRU behaviour. setjmp() and longjmp() are now used for rollback (i.e. when memory pool overflow occurs). Function names are now all uniformly prefixed with `gray_'. * src/smooth/ftgrays.c: Include <setjmp.h>. (ErrRaster_MemoryOverflow): New macro. (TArea): New type to store area values in each cell (using `int' was too small on 16-bit systems). <limits.h> is included to properly get the needed data type. (TCell, TRaster): Use it. (TRaster): New element `jump_buffer'. (gray_compute_cbox): Use `RAS_ARG' as the only parameter and get `outline' from it. (gray_record_cell): Use longjmp(). (gray_set_cell): Use gray_record_cell() for error handling. (gray_render_line, gray_render_conic, gray_render_cubic): Simplify. (gray_convert_glyph_inner): New function, using setjmp(). (gray_convert_glyph): Use it. Provide a public API to manage multiple size objects for a given FT_Face in the new header file `ftsizes.h'. * include/freetype/ftsizes.h: New header file, * include/freetype/internal/ftobjs.h: Use it. Remove declarations of FT_New_Size and FT_Done_Size (moved to ftsizes.h). * include/freetype/config/ftheader.h (FT_SIZES_H): New macro. * src/base/ftobjs.c (FT_Activate_Size): New function. * src/cache/ftcmanag.c: Include ftsizes.h. (ftc_manager_init_size, ftc_manager_flush_size): Use FT_Activate_Size.
David Turner c4f622c3 2001-10-07T10:39:03 * src/smooth/ftgrays: "setjmp/longjmp" is now used for rollback (i.e. when memory pool overflow occurs), function names are now all prefixed with "gray_", and a new type (TArea) is defined to store area value in each cell (using "int" was too small on 16-bit systems)..

Replaced with files local to the module. All extra error codes have been moved to `fterrors.h'. * src/sfnt/ttpost.h: Move error codes to `fterrors.h'. * src/autohint/aherrors.h, src/cache/ftcerror.h, src/cff/cfferrs.h, src/cid/ciderrs.h, src/pcf/pcferror.h, src/psaux/psauxerr.h, src/psnames/psnamerr.h, src/raster/rasterrs.h, src/sfnt/sferrors.h, src/smooth/ftsmerrs.h, src/truetype/tterrors.h, src/type1/t1errors.h, src/winfonts/fnterrs.h: New files defining the error names for the module it belongs to. * include/freetype/ftmoderr.h: New file, defining the module error offsets. Its structure is similar to `fterrors.h'. * include/freetype/fterrors.h (FT_NOERRORDEF): New macro. (FT_ERRORDEF): Redefined to use module error offsets. All internal error codes are now public; unused error codes have been removed, some are new. * include/freetype/config/ftheader.h (FT_MODULE_ERRORS_H): New macro. * include/freetype/config/ftoption.h (FT_CONFIG_OPTION_USE_MODULE_ERRORS): New macro. All other source files have been updated to use the new error codes; some already existing (internal) error codes local to a module have been renamed to give them the same name as in the base module. All make files have been updated to include the local error files. * src/cid/cidtokens.h: Replaced with... * src/cid/cidtoken.h: This file for 8+3 consistency. * src/raster/ftraster.c: Use macros for header file names.

Fix compiler warnings. * src/base/ftcalc.c: Fix (potential) compiler warnings. * src/base/ftcalc.c (FT_SqrtFixed): Corrected/optimized the 32-bit fixed-point square root computation. It is now used even with 64-bits integers, as it is _much_ faster than calling FT_Sqrt64 :-) * src/base/ftbbox.c: Removed invalid "#include FT_BEZIER_H" line. * 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). * 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.
David Turner caf72cd6 2001-04-25T18:11:16 * src/base/ftbbox.c (BBox_Cubic_Check): rewrote function to use direct computations with 16.16 values instead of sub-divisions.

Added comments to be included in a new API Reference section. * src/*/*: removed the use of FT_SOURCE_FILE, etc.. now, each component needs to added its own directory to the include path at compile time. Modified all "rules.mk" and "descrip.mms" accordingly..
Werner Lemberg 914b289f 2001-03-10T17:07:42 * src/*/*.c: Added many casts to make code more 64bit-safe.

(FT2_PUBLIC_FILE, FT2_CONFIG_FILE, FT2_INTERNAL_FILE): Use directory names directly. Make them configurable. Use `##' to strip leading and trailing spaces from arguments. * builds/unix/ft2unix.h: Adapted. * src/base/ftsystem.c (ft_alloc, ft_realloc, ft_free, ft_io_stream, ft_close_stream): Use FT_CALLBACK_DEF. * builds/unix/ftsystem.c: Use new header scheme. (FT_Done_Memory): Use free() from FT_Memory structure. * src/base/ftinit.c, src/base/ftmac.c: Header scheme fixes. * include/freetype/config/ft2build.h (FT2_CONFIG_ROOT, FT2_PUBLIC_FILE, FT2_CONFIG_FILE, FT2_INTERNAL_FILE, FT_SOURCE_FILE): Use `##' operator to be really ANSI C compliant.
