Alexei Podtelezhnikov 7b73cb0707 [smooth] Formalize Harmony LCD rendering.
This generalizes magic outline shifts that make Harmony LCD
rendering work in terms of precise two-dimensional RGB subpixel
positions. These coordinates are now set in time of the `smooth'
module initialization and later used to shift a glyph outline for
rendering. FT_RENDER_MODE_LCD and FT_RENDER_MODE_LCD_V use the same
coordinates. The letter, however, rotates them before using.
The LCD bitmap padding is also calculated using these coordinates.

Shao Yu Zhang f04d81751a [sfnt] Preliminary support of coloured layer outlines.
This commit enables OpenType's COLR/CPAL table handling; a typical
application are color emojis that can be scaled to any size.

If the color palette does not exist or is invalid, the rendering
step rasterizes the outline instead.  The current implementation
assumes that the foreground is black.

Enable this by defining option TT_CONFIG_OPTION_COLOR_LAYERS.

There are still some issues with metrics; additionally, an API to
fetch color layers is missing.

Werner Lemberg 7bfcaacaf5 [sfnt] Adjust behaviour of PS font names for variation fonts.
* src/sfnt/sfdriver.c (sfnt_get_var_ps_name): Use a named instance's
PS name only if no variation is applied.
2017-10-07 13:14:38 +02:00
Werner Lemberg f89c67f043 [cff, truetype] Adjust behaviour of named instances.
This commit completely separates the interaction between named
instances and variation functions.  In particular, resetting the
variation returns to the current named instance (if set) and not to
the base font.

As a side effect, variation functions no longer change the named
instance index.

* src/cff/cffobjs.c (cff_face_init): Use MM service's `set_instance'
function.
Also apply `MVAR' table to named instances.

* src/truetype/ttgxvar.c (TT_Get_MM_Var): Add cast.
(tt_set_mm_blend): No longer check whether requested variation
coincides with a named instance.
(TT_Set_Var_Design): Use current named instance for default
coordinates.
* src/truetype/ttobjs.c (tt_face_init): Use `TT_Set_Named_Instance'.

Werner Lemberg 8c92f7622c Make `FT_FACE_FLAG_VARIATION' work.
* include/freetype/internal/tttypes.h (TT_Face): Remove
`is_default_instance'; this can be replaced with a combination of
`FT_IS_VARIATION' and `FT_IS_INSTANCE'.

* src/cff/cffdrivr.c (cff_get_advances): Updated.

* src/sfnt/sfdriver.c (sfnt_get_ps_name), src/sfnt/sfobjs.c
(sfnt_init_face): Updated.

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.

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

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.

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.

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
`PS_Decoder'.

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.

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

* 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.

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.
