[psaux] Fix CFF advance widths. (#52466) Glyph advance widths were being written to the new `PS_Decoder' but not saved to the underlying format specific decoder. This caused pure CFF fonts to have bad advance width. * include/freetype/internal/psaux.h (PS_Decoder): Change `glyph_width' field to pointer. Remove unused fields. * src/psaux/psobjs.c (ps_decoder_init): Change `glyph_width' from copy to reference. Remove unused. * src/psaux/psft.c (cf2_setGlyphWidth): Update code.

Use Adobe hinting engine for `light' hinting of both CFF and Type 1. Since Ewald Hew factored the Adobe hinting engine out of the CFF driver code, we can now use it on Type 1 (and CID) font formats, as both have the same hinting philosophy. This change activates the Adobe hinter when in LIGHT mode, and therefore always unless explicitly asking for the auto-hinter. This makes LIGHT behavior consistent with CFF fonts. As of this commit, the hinting engine table looks as follows. LIGHT NORMAL ------------------------- TrueType Auto v40 CFF Adobe Adobe Type 1 Adobe Adobe

[psaux] Fix PostScript interpreter rewinding in Type 1 mode. (#52251) The interpreter in Type 1 mode rewinds the charstring after collecting all hints for building the initial hintmap (commit d52dd7f). However, some charstrings use `endchar' in a final subroutine call, rewinding to the start of that subroutine, and only a small section of the actual glyph is drawn. * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_cmdENDCHAR>: Ensure we are on the top level charstring before rewinding.

[smooth] Fix complex rendering at high ppem. We used to split large glyphs into horizontal bands and continue bisecting them still horizontally if that was not enough. This is guaranteed to fail when a single scanline cannot fit into the rendering memory pool. Now we bisect the bands vertically so that the smallest unit is a column of the band height, which is guranteed to fit into memory. * src/smooth/ftgrays.c (gray_convert_glyph): Implement it.

[smooth] Improve complex rendering at high ppem. At large sizes almost but not exactly horizontal segments can quickly drain the rendering pool.

Fixes for rendering. The Type 1 advance width calculation passes null for glyph slot, etc, which can cause null pointer access in the new interpreter. Fall back to the old one for now. Fix the large glyph retry code and ensure hinting and scaling flags are set properly. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Add a check for metrics_only. Set the `force_scaling' flag. (T1_Parse_Glyph): Updated. (T1_Load_Glyph): Add `hinting' and `scaled' flags.

[sfnt, truetype] Register the tags for marginal fonts.
The first 32bit of standard TrueType variants is 0x00010000,
`OTTO', `ttcf', `true' or `typ1'. 2 marginal dfonts on legacy Mac
OS X, Keyboard.dfont and LastResort.dfont, have the sfnt resources
starting 0xA5 followed by `kbd' or `lst'. Considering the following
data could be parsed as conventional TrueType fonts, the header
checking is updated to allow these tags. It seems that recent Mac
OS X has already switched to normal TTF for these fonts.

Fix multiple calls of `FT_Bitmap_Convert'. The documentation of `FT_Bitmap_Convert' says that multiple calls do proper reallocation of the target FT_Bitmap object. However, this failed for the sequence non-empty bitmap empty bitmap non-empty bitmap Reason was that `FT_Bitmap_Convert' only reallocated the bitmap buffer if it became too small; it didn't make the buffer smaller. For an empty bitmap following a non-empty one, only the buffer dimension got set to zero, without deallocation. If the next call was a non-empty buffer again, an assertion in `ft_mem_qrealloc' was triggered. * src/base/ftbitmap.c (FT_Bitmap_Convert): Always reallocate target buffer to the correct size. * docs/CHANGES: Document it.

Handle some integer overflow run-time errors (#46149, #48979). 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.

[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. As a
NORMAL option, warping substitutes normal hinting.
* src/autofit/afcjk.c (af_cjk_hints_apply): Updated.
* src/autofit/aflatin.c (af_latin_hints_apply): Updated.
* src/autofit/aflatin2.c (af_latin2_hints_apply): Updated.
* src/autofit/afloader.c (af_loader_load_glyph): Handle warping
phantom points as normal.
Remove remnants of raster pool. * include/freetype/internal/ftobjs.h (FT_LibraryRec): Remove `raster_pool' and `raster_pool_size' fields. * src/base/ftobjs.c (FT_New_Library), src/raster/ftrend1.c (ft_raster1_init), src/smooth/ftsmooth.c (ft_smooth_init): Updated.

Add new `slight' auto-hinting mode. This mode uses fractional advance widths and doesn't scale glyphs horizontally, only applying vertical scaling and hinting. At the same time, the behaviour of the `light' auto-hinter gets restored for backwards compatibility: Both vertical and horizontal scaling is again based on rounded metrics values (this was changed in a commit from 2017-03-30 as a side effect). To be more precise, the behaviour is restored for TrueType fonts only; for other font formats like Type 1, this is a new feature of the `light' hinting mode. * include/freetype/freetype.h (FT_LOAD_TARGET_SLIGHT): New macro.

* src/truetype/ttgxvar.c (tt_hvadvance_adjust): Handle
glyph indices larger than `mapCount' as described in the
specification.
[truetype] Allow linear scaling for unhinted rendering (#50470). * src/truetype/ttdriver.c (tt_size_request): Revert change from 2011-07-16; the intended metrics fix seems now to be implemented in a different way, making the patch unnecessary. Note that this change was usually patched out by all major GNU/Linux distributions due to heavy side effects. * src/truetype/ttgload.c (compute_glyph_metrics, TT_Load_Glyph): Refer to the metrics of the `TT_Size' object.

[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.

[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

[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'). If one of the two characters has a large serif, say, it can happen that FreeType must select between two different values, having a 50% chance to use the wrong one. As a result, rendering at larger PPEM values could yield uneven lowercase glyph heights.

* src/cff/cffobjs.c (cff_face_init), src/truetype/ttobjs.c
(tt_face_init): Indent first tracing message from SFNT driver.
[truetype] Various minor fixes. * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Check instruction size only if we do native hinting. (TT_Load_Glyph): Trace returned error code. * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Trace returned error code. (tt_size_ready_bytecode): Don't run `prep' table if `fpgm' table is invalid.
