- This commit (mainly for 32bit CPUs) is the first of a series of - similar commits to handle known integer overflows. Basically, all - of them are harmless, since they affect rendering of glyphs only, - not posing security threats. It is expected that fuzzying will show - up more overflows, to be fixed in due course. - - The idea is to mark places where overflows can occur, using macros - that simply cast to unsigned integers, because overflow arithmetic - is well defined in this case. Doing so suppresses run-time errors - of sanitizers without adding computational overhead. - - * include/freetype/internal/ftcalc.h (OVERFLOW_ADD_INT, - OVERFLOW_SUB_INT, OVERFLOW_MUL_INT, OVERFLOW_ADD_LONG, - OVERFLOW_SUB_LONG, OVERFLOW_MUL_LONG): New macros. - - * src/base/ftcalc.c (FT_RoundFix, FT_CeilFix, FT_Matrix_Multiply, - FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled, - ft_corner_orientation): Use new macros. - - * src/base/ftoutln.c (FT_Outline_Get_Orientation): Use new macros. - -2017-05-28 Werner Lemberg <wl@gnu.org> - - * include/freetype/internal/ftcalc.h (FLOAT_TO_FIXED): Remove. - - This macro is not used. - -2017-05-28 Werner Lemberg <wl@gnu.org> - - [cff] s/cf2_floatToFixed/cf2_doubleToFixed/. - - The new name better describes what the macro actually does; - additionally, we don't need a trailing `f' for literals (there was - only a single such instance in the code, but this caused a clang - warning because the macro itself uses `double' literals). - - * src/cff/cf2blues.c, src/cff/cf2blues.h, src/cff/cf2fixed.h, - src/cff/cf2font.c, src/cff/cf2hints.c: Updated. - -2017-05-28 Werner Lemberg <wl@gnu.org> - - Fix negation of INT_MIN and LONG_MIN (#46149). - - * src/base/ftcalc.c (FT_MOVE_SIGN): Add argument to pass unsigned - value, to be used as the result. - (FT_MulDiv, FT_MulDiv_No_Round, FT_DivFix, FT_MulFix, - FT_Vector_NormLen): Updated. - -2017-05-27 Werner Lemberg <wl@gnu.org> - - [truetype] Fix handling of design coordinates (#51127). - - * src/truetype/ttgxvar.c (tt_set_mm_blend): Compute all design - coordinates if we have to create the `blends->coord' array. - (TT_Get_MM_Blend, TT_Get_Var_Design): Select default instance - coordinates if no instance is selected yet. - -2017-05-24 Werner Lemberg <wl@gnu.org> - - [bdf, pcf] Support ISO646.1991-IRV character encoding (aka ASCII). - - Problem reported by Marek Kašík <mkasik@redhat.com>, cf. - - https://bugzilla.redhat.com/show_bug.cgi?id=1451795 - - * src/bdf/bdfdrivr.c (BDF_Face_Init), src/pcf/pcfdrivr.c - (PCF_Face_Init): Implement it. - -2017-05-20 Nikolaus Waxweiler <madigens@gmail.com> - - [truetype] Always use interpreter v35 for B/W rendering (#51051). - - * src/truetype/ttgload.c (tt_loader_init) - [TT_SUPPORT_SUBPIXEL_HINTING_MINIMAL]: Adjust - `subpixel_hinting_lean', `grayscale_cleartype', and - `vertical_lcd_lean' accordingly. - - * src/truetype/ttinterp.c (Ins_GETINFO): Updated. - (TT_RunIns): Update `backward_compatibility' flag. - -2017-05-20 Alexei Podtelezhnikov <apodtele@gmail.com> - - [smooth] Implement minimal dynamic padding for LCD filtering. - - Extra bitmap padding for LCD filtering depends on the filter. The - default 5-tap filter needs 2 extra subpixels. The light 3-tap filter - needs only 1 extra subpixel. This space could be already available - due to rounding. In order to optimize the padding, we now expand - CBox for the given filter weights before rounding. - - This change breakes current Skia (and Firefox). - - * include/freetype/internal/ftobjs.h (FT_LibraryRec) - [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Remove `lcd_extra' field. - - * src/base/ftlcdfil.c (FT_Library_SetLcdFilterWeights, - FT_Library_SetLcdFilter): Remove `lcd_extra' initializations. - - * src/smooth/ftsmooth.c (ft_smooth_render_generic): Implement dymanic - LCD padding. - -2017-05-15 Werner Lemberg <wl@gnu.org> - - [sfnt] Return proper scaling values for SBIX bitmaps. - - Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>. - - * src/sfnt/ttsbit.c (tt_face_load_strike_metrics): Implement it. - -2017-05-15 Werner Lemberg <wl@gnu.org> - - [truetype] Fix error handling for embedded bitmaps. - - Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>. - - * src/truetype/ttgload.c (TT_Load_Glyph) - [TT_CONFIG_OPTION_EMBEDDED_BITMAPS]: Handle error if font is not - scalable. - -2017-05-15 Alexei Podtelezhnikov <apodtele@gmail.com> - - [autofit] Make autohint warping NORMAL option. - - This moves warping option from LIGHT to NORMAL mode. This makes LIGHT - truly void of hinting in x-direction, with left side bearing never - changed and right side bearing only altered by advance rounding. - Therefore, LIGHT is now ready to return fractional advance.

-2017-02-13 Werner Lemberg <wl@gnu.org> - - [autofit] Prevent overlapping blue zones. - - Problem reported as - - https://github.com/google/fonts/issues/632 - - The font in question (Nunito) has values 705 and 713 for the - reference and overshoot values, respectively, of the first blue - zone. Blue zone 2, however, has value 710 for both the reference - and overshoot. At 12ppem, reference and overshoot of blue zone 0 - becomes 8px, while blue zone 2 becomes 9px. - - A peculiarity of this font is that the tops of isolated vertical - stems like `N' have a slight overshoot also. The auto-hinter tries - to find the nearest blue zone using the *original* coordinates. For - vertical stems, this is value 713. For normal horizontal tops like - in character `E', this is value 710. Since value 713 is mapped to - 8px but value 710 to 9px, `N' and similar characters are one pixel - higher than `E', which looks very bad. - - This commit sanitizes blue zones to avoid such a behaviour. - - * src/autofit/aflatin.c (af_latin_sort_blue): New function. - (af_latin_metrics_init_blues): Sort blue values and remove overlaps. - -2017-02-12 Alexei Podtelezhnikov <apodtele@gmail.com> - - * src/smooth/ftgrays.c (gray_sweep): Improve code. - -2017-02-06 Werner Lemberg <wl@gnu.org> - - [truetype] Implement `VVAR' table support. - - * src/truetype/ttgxvar.h (GX_HVarTable): Renamed to... - (GX_HVVarTable): ...This. - (GX_Blend): Add fields for `VVAR' table handling. - Other minor updates. - - * src/truetype/ttgxvar.c (ft_var_load_hvar): Renamed to... - (ft_var_load_hvvar): ...This. - Handle VVAR loading also (controlled by an additional parameter). - (tt_hadvance_adjust): Renamed to... - (tt_hvadvance_adjust): ...This. - Handle application of advance height also (controlled by an - additional parameter). - (tt_hadvance_adjust, tt_vadvance_adjust): Wrappers for - `tt_hvadvance_adjust'. - - * src/truetype/ttdriver.c (tt_service_metrics_variations): Updated. - -2017-02-05 Werner Lemberg <wl@gnu.org> - - [autofit] Use better blue zone characters for lowercase latin. - - The number of lowercase characters for computing the top flat blue - zone value was too small (in most cases only `x' and `z').
