2014-05-01 Werner Lemberg <wl@gnu.org>
[autofit] Add blue-zone support for Devanagari.
This essentially moves the Devanagari script from the `Indic' hinter
to the `Latin' hinter. Thanks to Girish Dalvi
<girish.dalvi@gmail.com> for guidance with blue zone characters!
* src/autofit/afblue.dat: Add blue zone data for Devanagari.

2014-04-28 Werner Lemberg <wl@gnu.org>
[autofit] Introduce neutral blue zones to the latin module.
Such blue zones match either the top or the bottom of a contour. We
need them for scripts where accent-like elements directly touch the
base character (for example, some vowel signs in Devanagari, cf.
U+0913 or U+0914).
* src/autofit/afblue.hin (AF_BLUE_PROPERTY_LATIN_NEUTRAL): New
property.
* src/autofit/afblue.h: Regenerated.

af_latin_hints_compute_blue_edges): Handle neutral blue zones.
2014-04-25 Werner Lemberg <wl@gnu.org>
* src/autofit/hbshim.c: Partially revert commit from 2014-04-17.
Using input glyph coverage data is simply wrong.
Problem reported by Nikolaus Waxweiler <madigens@gmail.com> and
Mantas Mikulėnas <grawity@gmail.com>.
2014-04-23 Werner Lemberg <wl@gnu.org>
* src/raster/ftraster.c (Vertical_Sweep_Span): Use drop-out mode.
This spot has been missed while introducing support for various
drop-out modes years ago (including no drop-out mode, which this
commit fixes).
Problem reported by Patrick Thomas <pthomas505@gmail.com>.
2014-04-22 Werner Lemberg <wl@gnu.org>
* src/sfnt/pngshim.c (error_callback): s/longjmp/ft_longjmp/.
2014-04-20 Werner Lemberg <wl@gnu.org>
[autofit] Fix Savannah bug #42148.
The adaptation of the cjk auto-hinter module to blue stringsets in
2013-08-25 had three severe bugs. Mea culpa.
1. Contrary to the latin auto-hinter, characters for reference and
overshoot values of a blue zone are specified separately. Due to
the screwed-up change it didn't work at all.
2. A boolean comparison was erroneously replaced with a cast,
causing invalid results with the `^' operator later on. The
visual artifact caused by this problem is the topic of the bug
report.
3. Two flag values were inverted, causing incorrect assignment of
reference and overshoot values.
* src/autofit/afblue.dat: Fix CJK bluestrings, introducing a new
syntax to have both reference and overshoot characters in a single
string. This is error #1.
Add extensive comments.
* src/autofit/afblue.hin (AF_BLUE_PROPERTY_CJK_FILL): Removed, no
longer used.
(AF_BLUE_PROPERTY_CJK_TOP, AF_BLUE_PROPERTY_CJK_HORIZ): Fix values.
This is error #3.
* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
* src/autofit/afcjk.c (af_cjk_metrics_init_blues): Correct error #1.
Use character `|' to separate characters for reference and overshoot
values.
Improve tracing messages, synchronizing them with the latin
auto-hinter.
(af_cjk_hints_compute_blue_edges): Fix value of `is_top_right_blue'.
This is error #2.
(af_cjk_align_linked_edge): Add tracing message.
* src/autofit/afcjk.h (AF_CJK_IS_FILLED_BLUE): Removed, no longer
used.
2014-04-17 Werner Lemberg <wl@gnu.org>
[autofit] More coverage fixes for complex scripts.
* src/autofit/hbshim.c (af_get_coverage): Merge input glyph coverage
of GSUB lookups into output coverage. Otherwise, ligatures are not
handled properly.
Don't check blue zone characters for default coverage.
2014-04-17 Werner Lemberg <wl@gnu.org>
Make `FT_Get_SubGlyph_Info' actually work.
* src/base/ftobjs.c (FT_Get_SubGlyph_Info): Return FT_Err_Ok
if there is no error.
2014-04-15 Werner Lemberg <wl@gnu.org>
[afblue.pl]: Minor improvements.
* src/tools/afblue.pl: Allow whitespace before comments.
Ignore whitespace in strings.
2014-04-14 Werner Lemberg <wl@gnu.org>
[autofit] Improve coverage handling.
* src/autofit/hbshim.c (af_get_coverage): Don't exclude glyphs
appearing in the GPOS table if we are processing the default
coverage.
2014-04-13 David Weber <weber.aulendorf@googlemail.com>
[smooth] Fix stand-alone compilation.
* src/smooth/ftgrays.c (FT_BEGIN_STMNT, FT_END_STMNT): Define.
2014-04-12 Werner Lemberg <wl@gnu.org>
[autofit] Redesign the recognition algorithm of strong points.
In particular, local extrema without horizontal or vertical segments
are better recognized:
+ A + D
\ /
\ /
\ /
\ /
\ + C
\ /
B +/
If the distances AB and CD are large, point B wasn't previously
detected as an extremum since the `ft_corner_is_flat' function
`swallowed' BC regardless of its direction, tagging point B as weak.
The next iteration started at B and made `ft_corner_is_flat' swallow
point C, tagging it as weak also, et voilà.
To improve that, another pass gets now performed before calling
`ft_corner_is_flat' to improve the `topology' of an outline: A
sequence of non-horizontal or non-vertical vectors that point into
the same quadrant are handled as a single, large vector.
Additionally, distances of near points are now accumulated, which
makes the auto-hinter handle them as if they were prepended to the
next non-near vector.
This generally improves the auto-hinter's rendering results.
* src/autofit/afhints.c (af_glyph_hints_reload): Implement it.
* src/autofit/afhints.h (AF_FLAGS): Remove no longer used flag
`AF_FLAG_NEAR'.
2014-04-05 Werner Lemberg <wl@gnu.org>
[autofit] Improve scoring algorithm for identifying stems.
Problem reported by Karsten Lücke <karsten.luecke@kltf.de>.
The new algorithm takes care of the width of stems: If the distance
between two segments is larger than the largest stem width, the
demerits quickly increase for larger distances. This improves
hinting of slanted fonts (especially if the inner parts of serifs
have non-horizontal `shoulders'), avoiding false stem links.
* src/autofit/aflatin.c (af_latin_hints_link_segments): Use largest
stem width (if available) to compute better demerits for distances
between stems.
(af_latin_hints_detect_features): Pass stem width array and array
size.
(af_latin_metrics_init_widths): Updated to use original algorithm.
(af_latin_hints_apply): Updated to use new algorithm.
* src/autofit/aflatin.h: Updated.
* src/autofit/afcjk.c: Updated.
2014-04-03 Werner Lemberg <wl@gnu.org>
Don't require `gzip' module for `sfnt'.
Reported by Preet <prismatic.project@gmail.com>.
* src/sfnt/sfobjs.c (woff_open_font): Guard use of
FT_Gzip_Uncompress with FT_CONFIG_OPTION_USE_ZLIB.
2014-03-27 Werner Lemberg <wl@gnu.org>
Fix Savannah bug #38235.
Work around a bug in pkg-config version 0.28 and earlier: If a
variable value gets surrounded by doublequotes (in particular values
for the `prefix' variable), the prefix override mechanism fails.
* builds/unix/freetype2.in: Don't use doublequotes.
* builds/unix/unix-def.in (freetype.pc): Escape spaces in directory
names with backslashes.
2014-03-24 Werner Lemberg <wl@gnu.org>

now the default.
o First use `pkg-config' for library detection, then fall back to
other tests.
* builds/unix/configure.raw (--with-zlib, --with-bzip2, --with-png,
--with-harfbuzz): Rewrite.
Use new `xxx_reqpriv', `xxx_libpriv', and `xxx_libstaticconf'
variables to collect data for `freetype2.pc' and `freetype-config'.

* src/cff/cf2ft.c (cf2_initLocalRegionBuffer,
cf2_initGlobalRegionBuffer): It is possible for a charstring to call
a subroutine if no subroutines exist. This is an error but should
not trigger an assert. Split the assert to account for this.
2014-02-28 Dave Arnold <darnold@adobe.com>
[cff] Fix Savannah bug #41697, part 1.
* src/cff/cf2hints.c (cf2_hintmap_build): Return when `hintMask' is

2014-02-26 Werner Lemberg <wl@gnu.org>
[bdf] Fix Savannah bug #41692.
bdflib puts data from the input stream into a buffer in chunks of
1024 bytes. The data itself gets then parsed line by line, simply
increasing the current pointer into the buffer; if the search for
the final newline character exceeds the buffer size, more data gets
read.
However, in case the current line's end is very near to the buffer
end, and the keyword to compare with is longer than the current
line's length, an out-of-bounds read might happen since `memcmp'
doesn't stop properly at the string end.
* src/bdf/bdflib.c: s/ft_memcmp/ft_strncmp/ to make comparisons
stop at string ends.
2014-02-17 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>

introduced in Perl version 5.10.
2014-02-04 Werner Lemberg <wl@gnu.org>
Fix compilation with MinGW.

2014-01-26 Werner Lemberg <wl@gnu.org>
[autofit] Introduce two more slots for standard characters.
This is useful for OpenType features like `c2sc' (caps to small
caps) that don't have lowercase letters by definition, or other
features that mainly operate on numerals.

[autofit] Fix Indic scripts.
Split the single, incorrect Indic entry into separate scripts so
that the covered ranges are the same: Bengali, Devanagari, Gujarati,
Gurmukhi, Kannada, Limbu, Malayalam, Oriya, Sinhala, Sundanese,
Syloti Nagri, Tamil, Telugu, and Tibetan. At the same time, remove
entries for Meetai Mayak and Sharada – the Unicode ranges were
incorrect (and nobody has complained about that), fonts are scarce
for those scripts, and the Indic auto-hinter support is rudimentary
anyways.
* src/autofit/afscript.h: Updated, using AF_CONFIG_OPTION_INDIC and
AF_CONFIG_OPTION_CJK.
* src/autofit/afstyles.h (STYLE_DEFAULT_INDIC): New auxiliary macro.
Use it, together with AF_CONFIG_OPTION_INDIC and
AF_CONFIG_OPTION_CJK, to update.
* src/autofit/afranges.c [AF_CONFIG_OPTION_INDIC]: Updated.
[!AF_CONFIG_OPTION_INDIC, !AF_CONFIG_OPTION_CJK]: Removed.

zones.
2014-01-03 Werner Lemberg <wl@gnu.org>
[autofit] Fix handling of default coverages.
* src/autofit/afglobal.c (af_face_globals_compute_style_coverage):

auxiliary macros; use them to define styles for Cyrillic, Greek, and
Latin.
* src/autofit/afcover.h: Remove coverage for oldstyle figures.
Since those digits are used in combination with ordinary letters, it
makes no sense to handle them separately.

src/autofit/aflatin.c: Updated.
2013-12-30 Werner Lemberg <wl@gnu.org>
[autofit] Don't combine multiple features into one set.
Combining them, as originally envisioned, would lead to much more
complicated code, as investigations have shown meanwhile. The major
drawback is that we run out of available style slots much earlier.
However, this is only a theoretical issue since we don't support a
large number of scripts currently.
* src/autofit/afcover.h: Replace `COVERAGE_{1,2,3}' macros with
a single-element `COVERAGE' macro, sort the elements by the feature
tags, and add entry for `ruby'.
* src/autofit/aftypes.h: Updated.
* src/autofit/hbshim.c: Updated.

`hb_font'.
* src/autofit/afglobal.c (af_face_globals_new)

headers.

(af_autofitter_init): Updated.
2013-12-27 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[ftrfork] Fix the face order difference between POSIX and Carbon.
The fragmented resources in Suitcase and .dfont should be reordered
when `POST' resource for Type1 is being restored, but reordering of
sfnt resources induces the different face order. Now the ordering
is restricted to `POST' resource only, to prevent the different
order issue (e.g. the face index in the fontconfig cache generated
with Carbon framework is incompatible with that by FreeType 2
without Carbon framework.) Found by Khaled Hosny and Hin-Tak Leung.

2013-12-21 Werner Lemberg <wl@gnu.org>
[autofit] Introduce `coverages'.
Coverages are the interface to the HarfBuzz library to acces
OpenType features for handling glyphs not addressable by the cmap.
Right now, compilation of HarfBuzz is only added to the development
build. A solution for standard build mode will be delayed until
HarfBuzz gets split into two libraries to avoid mutual dependencies
between FreeType and HarfBuzz.
Note that this is only a first step in handling coverages, basically
providing the framework only. Code for handling selected OpenType
features (this is, actually using the data in `afcover.h') will
follow.

[truetype] Next round in phantom point handling.
Greg Hitchcock provided very interesting insights into the
complicated history of the horizontal positions of the TSB and BSB
phantom points.
* src/truetype/ttgload.c (TT_LOADER_SET_PP)
[TT_CONFIG_OPTION_SUBPIXEL_HINTING]: Use `subpixel_hinting' and

[truetype] Fix phantom point handling.
This is a further improvement to the changes from 2013-11-06.
* src/truetype/ttgload.c (TT_Hint_Glyph): Horizontal phantom points
are rounded horizontally, vertical ones are rounded vertically.
(TT_LOADER_SET_PP): The horizontal position of vertical phantom
points in pre-ClearType mode is zero, as shown in the OpenType
specification.
2013-12-02 Werner Lemberg <wl@gnu.org>
[truetype] Fix change from 2013-11-20.
Problem reported by Akira Kakuto <kakuto@fuk.kindai.ac.jp>.
* src/truetype/ttgload.c (TT_Load_Simple_Glyph): Protect call to
`Update_Max' with both a TT_USE_BYTECODE_INTERPRETER guard and a
`IS_HINTED' clause.
Also remove redundant check using `maxSizeOfInstructions' – in
simple glyphs, the bytecode data comes before the outline data, and
a validity test for this is already present.
2013-11-27 Werner Lemberg <wl@gnu.org>

We now follow the `official' announcement from Microsoft (on the
OpenType mailing list, which unfortunately hasn't a public archive).
* include/freetype/tttables.h (TT_OS2):
s/usLowerPointSize/usLowerOpticalPointSize/,
s/usUpperPointSize/usUpperOpticalPointSize/.

default values.
2013-11-13 Werner Lemberg <wl@gnu.org>

2013-11-13 Werner Lemberg <wl@gnu.org>
Simplify header file hierarchy.
This large patch changes the header file directory layout from
`include/freetype/...' to `include/...', effectively removing one
level. Since the file `ft2build.h' is also located in `include'
(and it stays there even after installation), all FreeType header
files are now in a single directory.
Applications that use (a) `freetype-config' or FreeType's
`pkg-config' file to get the include directory for the compiler, and
(b) the documented way for header inclusion like
#include <ft2build.h>
#include FT_FREETYPE_H
...
don't need any change to the source code.
* include/freetype/*: Move up to...
* include/*: ... this directory.
* builds/amiga/include/freetype/*: Move up to...
* builds/amiga/include/*: ... this directory.
*/*: Essentially do `s@/freetype/@/@' where appropriate.
* CMakeList.txt: Simplify.
* builds/unix/freetype-config.in, builds/unix/freetype2.in: For
`--cflags', return a single directory.
* builds/unix/install.mk (install): No longer try to remove `cache'
and `internal' subdirectories; instead, remove the `freetype'
subdirectory.
2013-11-12 Werner Lemberg <wl@gnu.org>

2013-11-01 Werner Lemberg <wl@gnu.org>
[truetype] Minor code refactoring.
Two benefits: The allocated FDEF (and IDEF) array gets slightly
smaller, and the `ttdebug' demo program has access to function
numbers without additional costs.
Fortunately, no changes to FontForge are necessary – this is the
only external TrueType debugger I know of, but others may exist and
should check the code accordingly.
* src/truetype/ttinterp.h (TT_CallRec): Replace `Cur_Restart' and
`Cur_End' with a pointer to the corresponding `TT_DefRecord'
structure.
* src/truetype/ttinterp.c (DO_JROT, DO_JMPR, DO_JROF, Ins_ENDF,
Ins_CALL, Ins_LOOPCALL, Ins_UNKNOWN, TT_RunIns <Invalid_Opcode>):
Updated.
2013-10-27 Werner Lemberg <wl@gnu.org>
[sfnt] Implement support for `OS/2' table version 5.
See
http://typedrawers.com/discussion/470/new-microsoft-size-specific-design-selection-mechanism
for the announcement.
* include/freetype/tttables.h (TT_OS2): Add fields
`usLowerPointSize' and `usUpperPointSize'. Since FreeType returns
this structure only as a pointer through `FT_Get_Sfnt_Table', there
shouldn't be any ABI problems.
* src/sfnt/ttload.c (tt_face_load_os2): Implement it.

[arm] Fix thumb2 inline assembly under LLVM.
When using `ADD' with an immediate operand, the instruction is
actually `ADD Rd, Rn, #<imm12>', that is, the maximum of the
immediate operand cannot exceed 4095. It will fail to compile with
LLVM.
However, in GCC, due to some legacy compatibility considerations,
`ADD.W' will be automatically emitted when the immediate operand is
larger than 4095.
* builds/unix/ftconfig.in, include/freetype/config/ftconfig.h
(FT_MulFix_arm) [__GNUC__]: Support clang compiler.

[autofit] Improve tracing of `latin' hinter.
* src/autofit/aflatin.c (af_latin_metrics_init_blues): Report blue
zone types.
(af_latin_metrics_scale_dim): Report scaling changes due to x height
alignment.
Report scaled stroke width and blue zone values.
2013-10-03 Dave Arnold <darnold@adobe.com>
* src/cff/cf2font.c (cf2_computeDarkening): Avoid division by zero.
Note that the old code avoided using a region of the piecewise
linear function where the slope was zero. The recovery was to use a
different section of the function, which produced a different,
incorrect amount of darkening.
2013-10-02 Darrell Bellert <darrell.bellert@hl.konicaminolta.us>
* src/sfnt/ttload.c (tt_face_load_pclt): Fix `pclt_fields'.
2013-10-02 Dave Arnold <darnold@adobe.com>
* src/cff/cf2font.c (cf2_computeDarkening): Initialize darkenAmount.
This line was lost in commit 89ca1fd6 (from 2013-06-25). The effect
is to use a previous darkening amount when producing an unhinted,
unscaled outline. This can cause autohint samples in ftgrid and
ftview to be based on darkened CFF outlines instead of unhinted,
undarkened ones.
2013-09-29 Dave Arnold <darnold@adobe.com>
Fix Savannah bug #39295.
The bug was caused by switching to the initial hintmap (the one in
effect when `moveto' executes) just before drawing the final element
in the charstring. This ensured that the path was closed (in both
Character Space and Device Space). But if the final element was a
curve and if the final hintmap was different enough from the initial
one, then the curve was visibly distorted.
The first part of the fix is to draw the final curve using the final
hintmap as specified by the charstring. This corrects the
distortion but does not ensure closing in Device Space. It may
require the rasterizer to automatically generate an extra closing
line. Depending on the hintmap differences, this line could be from
zero to a couple pixels in length.
The second part of the fix covers the case where the charstring
subpath is closed with an explicit line. We now modify that line's
end point to avoid the distortion.
Some glyphs in the bug report font (TexGyreHeros-Regular) that show
the change are:
25ppem S (98)
24ppem eight (52)
25.5ppem p (85)
Curves at the *end* of a subpath are no longer distorted. However,
some of these glyphs have bad hint substitutions in the middle of a
subpath, and these are not affected.
The patch has been tested with a set of 106 fonts that shipped with
Adobe Creative Suite 4, together with 756 Open Source CFF fonts from
Google Fonts. There are 1.5 million glyphs, of which some 20k are
changed with the fix. A sampling of a few hundred of these changes
have been examined more closely, and the changes look good (or at
least acceptable).
* src/cff/cf2hints.h (CF2_GlyphPathRec): New element `pathIsClosing'
to indicate that we synthesize a closepath line.
* src/cff/cf2hints.c (cf2_glyphpath_init): Updated.
(cf2_glyphpath_pushPrevElem): If closing, use first hint map (for
`lineto' operator) and adjust hint zone.
For synthesized closing lines, use end point in first hint zone.
(cf2_glyphpath_lineTo): Take care of synthesized closing lines. In
particular, shift the detection of zero-length lines from character
space to device space.
(cf2_glyphpath_closeOpenPath): Remove assertion.
Updated.

FT_Open_Face: Improve external stream handling.
If the font's `clazz->init_face' function wants to swap to new

Better tracing of loaded glyphs.
Previously, the loading of a glyph was traced at level 4, if at all.
With this change, all font loading routines emit a tracing message
at level 1, making it easier to select tracing output (for example
using F2_DEBUG="any:1 afhints:7 aflatin:7").
* src/bdf/bdfdrivr.c (BDF_Glyph_Load): Add tracing message.

Instead of three dimensions (as used in the old blue string array)
we now use properties to do the same, saving one loop nesting level.
* src/autofit/afcjk.h: Remove old enumeration values superseded by
the new data in `afblue.h'.

2013-08-25 Werner Lemberg <wl@gnu.org>
[autofit] Introduce data file for blue strings.
The idea is to have a central file which gets processed by a Perl
script to create proper `.c' and `.h' files using templates. There
are two other reasons to do that:
. The data file should be easily readable. We use UTF-8 encoding
which then gets converted to single bytes.
. Since the number of supported scripts will increase soon, the
current usage of blue string arrays is a waste of space. Using
the Perl script it is possible to imitate jagged arrays,
defining enumeration constants as offsets into the arrays.
This commit only adds files without changing any functionality.
* src/autofit/afblue.dat: New data file.
* src/tools/afblue.pl: New Perl script for processing `afblue.dat'.
* src/autofit/afblue.cin, src/autofit/afblue.hin: New template files
for...
* src/autofit/afblue.c, src/autofit/afblue.c: New source files.
To avoid a dependency on Perl, we add them too.

[autofit] Improve handling of `near' points.
Points which are very near to each other are now marked as such.
The `weak' flag is then computed by using the `in' vector of the
first and the `out' vector of the last point of a group of near
points.
For example, this fixes the rendering of glyph `Oslash' in
`Roboto-Thin.ttf'.
* src/autofit/afhints.h (AF_Flags): New value `AF_FLAGS_NEAR'.
* src/autofit/afhints.c (af_glyph_hints_reload): Introduce
the heuristic value `near_limit' to decide whether the current point
is near to the previous one, then set `AF_FLAG_NEAR' accordingly.
Store good `in' vector (of last non-near point) in
`last_good_in_{x,y}' and use it as an argument to
`ft_corner_is_flat' if necessary.
2013-08-02 Werner Lemberg <wl@gnu.org>

[autofit] Introduce `writing systems'.
This patch adds a new top level to the auto-hinter's script class
hierarchy. It defines `writing systems' which can contain multiple

can be handled similarly.
Scripts are now named using four-letter OpenType tags.

[autofit] Fix segment classification for blue zones.
The old code (essentially unchanged since the very beginning)
incorrectly handled this configuration
x -o- x

o---------------o
as round. (`o' and `x' are on and off points, respectively).
This is a major change which should improve the rendering results
enormously for many TrueType fonts, especially in the range approx.
20-40ppem, fixing the appearance of many overshoots.
* src/autofit/aflatin.c (af_latin_metrics_init_blues): Look at the
first and last points of the segment, not the points right before

* builds/unix/ftconfig.in, include/freetype/config/ftconfig.h
(FT_MulFix_x86_64): New function.
2013-07-16 David Turner <digit@google.com>
Speed up ARMv7 support.
When building for ARMv7 with thumb2 instructions, the optimized
`FT_MulFix_arm' assembly routine was not being used.
The reason for this is in the `ftconfig.h' header, namely:
- The assembly routine uses the `smull' instruction which is not
available when generating Thumb-1 machine code. It is available
in Thumb-2 mode, though.
- The header was written a long time ago before Thumb-2 became
widely popular (e.g. with Android). So it simply doesn't use the
assembly routine if the `__thumb__' built-in macro is defined.
- When compiling in Thumb-2 mode, the compiler will define both
`__thumb__' and `__thumb2__'.
By checking for `(__thumb2__ || !__thumb__)', we ensure that the
assembly routine is only avoided when generating Thumb-1 code.
Given that this is performance-sensitive function, this improves
`ftbench' as follows on a Galaxy Nexus:

Add support for color embedded bitmaps (eg. color emoji).
A new load flag, FT_LOAD_COLOR, makes FreeType load color
embedded-bitmaps, following this draft specification
https://color-emoji.googlecode.com/git/specification/v1.html
which defines two new SFNT tables, `CBDT' and `CBLC' (named and
modeled after `EBDT' and `EBLC', respectively). The color bitmaps
are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA
pre-multiplied sRGB images. If PNG support is available, PNG color
images as defined in the same proposed specification are supported
also.
Note that color bitmaps are converted to grayscale if client didn't
ask for color.
