Alexei Podtelezhnikov 61d1818b5e Bitmap metrics presetting [1/2].
This mainly just extracts the code for presetting the bitmap metrics
from the monochrome, grayscale, and LCD renderers into a separate
function.

* src/base/ftobjs.c (ft_glyphslot_preset_bitmap): New function that
calculates prespective bitmap metrics for the given rendering mode.
* include/freetype/internal/ftobjs.h (ft_glyphslot_preset_bitmap):
Declare it.

* src/base/ftlcdfil.c (ft_lcd_padding): New helper function that adds
padding to CBox taking into account pecularities of LCD rendering.
* include/freetype/ftlcdfil.h (ft_lcd_padding): Declare it.

* src/raster/ftrend1.c (ft_raster1_render): Reworked to use
`ft_glyphslot_preset_bitmap'.

Ewald Hew ebb1735aa7 Move `psdecode' into `psobjs'.
As the former only contains a single procedure, move it into
`psobjs' for simplicity.  Also change the parameter order to the
conventional one.

* src/psaux/psdecode.c (ps_decoder_init): Moved to...
* src/psaux/psobjs.c: ...Here.
* src/psaux/psdecode.h, src/psaux/psobjs.h: Ditto.

Ewald Hew 93e3cffddf Change subfont synthesis for CID fonts.
Change `t1_make_subfont' to take in the Private dict record as an
argument.  This is because Type 1 and CID font records in FreeType
have this in different places.

* src/psaux/psobjs.c (t1_make_subfont): Change `T1_Face' to
`FT_Face' so that CID is also accepted.
Take `PS_Private' as an argument and let caller figure out where the
Private dict actually is.
Update references.

declaration.

* src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Update
call.

Ewald Hew 6eb03f8f5a Add missing objects (2/2).
Synthesize a `SubFont' object for Type 1 fonts.  This is used in the
interpreter to access Private dict data, which are stored in
different places for Type 1 and CFF.  This allows the same data to
be used in either mode.

* src/psaux/psobjs.c (t1_make_subfont): New procedure to copy
required values to a dummy `CFF_SubFont' object.  This is similar to
`cff_make_private_dict'.
* src/psaux/psobjs.h: Add the new declaration.

* include/freetype/internal/psaux.h, src/psaux/psauxmod.c: Ditto.
Add this to the PSAux Service for future use with CID fonts.

the interpreter and since it is currently stored in `CFF_Font', is
unavailable in Type 1 mode.

* include/freetype/internal/psaux.h (T1_Decoder, PS_Decoder): New
`cf2_instance' field.

* src/psaux/psdecode.c (ps_decoder_init): Copy `cf2_instance' to

Ewald Hew d23affe1ef Reorganize object fields.
Make some fields more generic, so that we can access them the same
way regardless of Type 1 or CFF.

* include/freetype/internal/psaux.h (PS_Builder): Change `TT_Face'
to `FT_Face'.
Remove unused fields.

* src/psaux/psft.c: Update all accesses of `PS_Builder.face'.
Add some asserts to guard against casting `T1_Face' as `TT_Face'.

suzuki toshiya 5c4e40d7fd [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.

See the discussion at
http://u88.n24.queensu.ca/exiftool/forum/index.php?topic=3931.0

* include/freetype/tttags.h (TTAG_0xA5kbd, TTAG_0xA5lst): New header
tags for Keyboard.dfont and LastResort.dfont.
* src/sfnt/sfobjs.c (sfnt_open_font): Accept the sfnt resource
starts with TTAG_0xA5kbd or TTAG_0xA5lst.
* src/truetype/ttobjs.c (tt_face_init): Accept the face with the
format tag is TTAG_0xA5kbd or TTAG_0xA5lst.

Werner Lemberg b45043c440 [sfnt, truetype] Improve handling of missing sbits.
Requested by Behdad.

Modern bitmap-only SFNTs like `NotoColorEmoji.ttf' don't contain
entries in the bitmap strike(s) for empty glyphs.  Instead, they
rely that a space glyph gets created from the font's metrics data.
This commit makes FreeType behave accordingly.

* include/freetype/fterrdef.h (FT_Err_Missing_Bitmap): New error
code.

* src/sfnt/ttsbit.c (tt_sbit_decoder_load_image): Change error codes
to make a distinction between a missing bitmap in a composite and a
simple missing bitmap.

* src/truetype/ttgload.c (TT_Load_Glyph): For a missing bitmap (in a
bitmap-only font), synthesize an empty bitmap glyph if metrics are
available.

Alexei Podtelezhnikov 410f3799b6 [smooth] Harmony LCD rendering.
This is a new technology for LCD-optimized rendering. It capitalizes
on the fact that each color channel grid is shifted by a third of a
pixel.  Therefore it is logical to render 3 separate monochrome
bitmaps shifting the outline by 1/3 pixel, and then combine them.
Importantly, the resulting output does not require additional LCD
filtering.

* src/smooth/ftsmooth.c (ft_smooth_render_generic)
[!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Implement new LCD-optimized
rendering.

* include/freetype/ftlcdfil.h, include/freetype/freetype.h,
include/freetype/config/ftoption.h, devel/ftoption.h: Updated
documentation.

Werner Lemberg f43b3094ef [base, truetype] New function `FT_Get_Var_Axis_Flags'.
The reserved `flags' field got a value in OpenType version 1.8.2;
unfortunately, the public `FT_Var_Axis' structure misses the
corresponding element.  Since we can't add a new field, we add an
access function.

* src/base/ftmm.c (FT_Get_Var_Axis_Flags): New function.

* include/freetype/ftmm.h (FT_VAR_AXIS_FLAG_HIDDEN): New macro.

Ben Wagner 7819aeb622 Avoid Microsoft compiler warnings (#51331).

Werner Lemberg fbe2fe4c75 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.

Alexei Podtelezhnikov ab2599ea3f [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).

Werner Lemberg 5aa6716a5e 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.
(FT_RENDER_MODE_SLIGHT): New render mode.

* include/freetype/internal/ftobjs.h (FT_Size_InternalRec): Add

Werner Lemberg d8a83232af Minor documentation improvement. 2016-11-06 12:33:18 +01:00
Werner Lemberg 37e193e935 Introduce a way of quickly retrieving (embedded) bitmap metrics.
`FT_Load_Glyph' doesn't generate a bitmap for a non-bitmap glyph
until the user calls `FT_Render_Glyph'.  However, it always
allocates memory for bitmaps and copies or decodes the contents of a
bitmap glyph, which can be quite slow for PNG data.

* include/freetype/freetype.h (FT_LOAD_BITMAP_METRICS_ONLY): New
macro.

* src/base/ftobjs.c (FT_Load_Glyph): Unset FT_LOAD_RENDER if
FT_LOAD_BITMAP_METRICS_ONLY is used.

* src/sfnt/ttsbit.c (tt_sbit_decoder_alloc_bitmap,
tt_sbit_decoder_load_bitmap): Add argument to control allocation of
the glyph slot.
(tt_sbit_decoder_load_image, tt_sbit_decoder_load_compound,
tt_face_load_sbit_image): Updated.

* src/pcf/pcfdrivr.c (PCF_Glyph_Load): Quickly exit if
`FT_LOAD_BITMAP_METRICS_ONLY' is set.

* src/pfr/pfrsbit.c, src/pfr/pfrsbit.h (pfr_slot_load_bitmap): Add

Werner Lemberg 24aa9c665e [autofit] Rewrite HarfBuzz interface to support character clusters.
Scripts like Khmer have blue zones that can't be directly
represented by Unicode characters.  Instead, it is necessary to let
HarfBuzz convert character clusters into proper glyph representation
forms, then deriving the blue zone information from the resulting
glyphs.

* src/autofit/hbshim.c, src/autofit/hbshim.h: Replaced by...
* src/autofit/afshaper.c, src/autofit/afshaper.h: ... these two new
files, providing a new API to access HarfBuzz.

The new API manages a HarfBuzz buffer with `af_shaper_buf_create'
and `af_shaper_buf_destroy'.  The buffer receives a UTF8 encoded
string with function `af_shaper_get_cluster', and the resulting
glyph data (indices, advance widths, vertical offsets) can be
iteratively accessed with function `af_shaper_get_elem'.

* src/autofit/afcjk.c (af_cjk_metrics_init_widths,
af_cjk_metrics_init_blues, af_cjk_metrics_check_digits): Updated.

Werner Lemberg 8502c98b15 Fix Savannah bug #45097.
We no longer `pollute' the namespace of possible header file names;
instead we move `ft2build.h' up by one level so that it gets
installed in the default include directory (e.g.,
/usr/local/include).  After this commit, only `ft2build.h' stays in
the compiler's include path.

No visible changes for the user who follows the standard FreeType
header inclusion rules.

* include/*: Move to ...
* include/freetype2/*: This directory, except `ft2build.h'.

* CMakeLists.txt (PUBLIC_HEADERS, PUBLIC_CONFIG_HEADERS,
PRIVATE_HEADERS), Jamfile (HDRMACRO, RefDoc), autogen.sh: Updated.
