2018-04-10 Nikolaus Waxweiler <madigens@gmail.com>
* CMakeLists.txt, builds/cmake/FindHarfBuzz.cmake: Extensive
modernization measures.
This brings up the minimum required CMake version to 2.8.12.
The installation paths follow the GNU defaults now, e.g. installing on a
64 bit host will place binaries into the lib64/ folder on e.g. Fedora.
Symbols are hidden by default (e.g. `-fvisibility=hidden' on GCC).
CMake will no longer look for a C++ compiler.
Library and .so version now match the Autotools build.
Comments in the build file and informational messages now use platform
agnostic example commands.
ftoption.h and ftconfig.h are written directly without a redundant `-new'
copy.
External dependencies are expressed as option()s and will turn up as such
in cmake-gui.
Internal: Properties such as dependencies and include directories are now
privately set on the freetype library instead of globally.
The CPack definitions have been cleaned up, the `make dist' has been
removed. Source packages generated with CPack don't contain Autotools
files and aren't used by the maintainters anyway.
On Windows, src/base/ftver.rc is compiled to decorate the library with
version and copyright information.
A pkg-config file is now generated and installed.

in above.
2018-04-01 Werner Lemberg <wl@gnu.org>
* builds/toplevel.mk (work): Use $(SEP).
This fixes the `make refdoc' using Cygwin: $(CAT) is `type' on this
platform, and this program only understands backslashes in paths.
Reported by Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com>.
2018-03-30 Werner Lemberg <wl@gnu.org>

2018-03-09 Chun-wei Fan <fanc999@yahoo.com.tw>
* CMakeLists.txt [win32]: Allow MSVC DLL builds (#53287).
Do not limit DLL builds to MinGW, since we already have
`__declspec(dllexport)' directives in `ftconfig.h'.
Also suppress more warnings for POSIX functions.
2018-03-08 Hugh McMaster <hugh.mcmaster@outlook.com>
Make installation of `freetype-config' optional (#53093).

[unix] Use -fvisibility=hidden.
It is now widely recommended that ELF shared libraries hide symbols
except those with explicit __attribute__((visibility("default"))).
This is supported by all major compilers and should rather be an
option in libtool.
* builds/unix/configure.raw: Add -fvisibility=hidden to CFLAGS.
* builds/unix/ftconfig.in, builds/vms/ftconfig.h,
include/freetype/config/ftconfig.h (FT_EXPORT): Use visibility
attribute.

2018-01-07 Ewald Hew <ewaldhew@gmail.com>
[psaux] Fix Type 1 glyphs with too many stem hints.
According to the CFF specification, charstrings can have up to 96 stem
hints. Due to hint replacement routines in Type 1 charstrings, some
glyphs are rejected by the Adobe engine, which implements the above
limit. This fix turns off hinting for such glyphs.
* src/psaux/pshints.c (cf2_hintmap_build): Reset the error from calling
`cf2_hintmask_setAll' on a problematic Type 1 charstring and turn off
hinting.
2018-01-06 Werner Lemberg <wl@gnu.org>

This is necessary in case the application's memory routines differ
from FreeType. A typical example is a Python application on Windows
that calls FreeType compiled as a DLL via the `ctypes' interface.
* include/freetype/ftmm.h, src/base/ftmm.c (FT_Done_MM_Var): Declare
and define.
* docs/CHANGES: Updated.

This is a better fix than the previous commit, which is now
reverted.
2018-01-03 Alexei Podtelezhnikov <apodtele@gmail.com>
Move internal LCD-related declarations.
* include/freetype/ftlcdfil.h (ft_lcd_padding, ft_lcd_filter_fir):
Move from here...
* include/freetype/internal/ftobjs.h: ... to here.
2018-01-03 Alexei Podtelezhnikov <apodtele@gmail.com>
* include/freetype/config/ftconfig.h (FT_EXPORT, FT_EXPORT_DEF)
[_MSC_VER]: Limit Visual C++ attributes.
2018-01-03 Werner Lemberg <wl@gnu.org>
[truetype] Make blend/design coordinate round-tripping work.

This reduces the amount of duplicated code across PostScript
drivers.
* src/cff/cffdrivr.c, src/cid/cidriver.c, src/type1/t1driver.c
({cff,cid,t1}_property_{get,set}): Moved to...

[sfnt] Fix charmap type 2 iterator (#52646).
The subsetted demo font of the report that exhibits the bug has a
very unusual type 2 cmap for Unicode(!): It contains only two
sub-headers, one for one-byte characters (covering the range 0x20 to
0xFA), and a second one for higher byte 0x01 (just for character
code U+0131).
Before this commit, the iterator wasn't able to correctly handle a
sub-header for higher byte 0x01.

In version 2.6.1, this has been disallowed to better reject

Apply it as a sed argument while copying `ftoption.h' to the

Simplify code of test that checks cpp's computation of bit length
(the test previously created an empty `ftoption.h' file and deleted
it immediately afterwards); without this change, it can happen on my

[psaux] Fix CFF advance widths. (#52466)
Glyph advance widths were being written to the new `PS_Decoder' but not

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.

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.

Rearrange `ps_builder_init' arguments to conventional order.
* src/psaux/psft.c (cf2_decoder_parse_charstrings): Add a check and
notice for `SubFont' in Type 1 mode.
2017-09-25 Ewald Hew <ewaldhew@gmail.com>
[psaux] Move `psdecode' into `psobjs'.

[psaux] Fix Type 1 hinting.
Type 1 hinting breaks sometimes when mid-charstring hints should
have been in the initial hintmap. This fix adds a preprocessing
pass that reads all hints and builds the correct initial hintmap
first, before proceeding to build the glyph outline.

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.

Type 1 mode. Type 1 requires large integers to be followed by
`div'; cf. `Adobe Type 1 Font Format', section 6.2.
<op == 255>: Push Type 1 four-byte numbers as `Int' always. This is
to ensure `div' and `callsubr' get values they can use.
2017-09-25 Ewald Hew <ewaldhew@gmail.com>

first operation in a Type 1 charstring.
(cf2_interpT2CharString): Remove unused variables.
<cf2_cmdHMOVETO, cf2_cmdVMOVETO, cf2_cmdRMOVETO>: `hsbw' or `sbw'
must be the first operation in a Type 1 charstring.

already present, instead of implementing `parse_state'.
2017-09-25 Ewald Hew <ewaldhew@gmail.com>
[psaux] Add Type 1 operations to Adobe CFF interpreter.
The following Type 1 specific ops have been added (copied from
`t1decode'):
closepath
vstem3
hstem3

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.

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

[otvalid] Fix handling of ValueRecords.
For GPOS pair positioning format 1 the description of ValueRecords
in the OpenType specification (1.8.2, from today) is wrong – the
offset has to be taken from the parent structure; in this case the
`PairSet' table.
* src/otvalid/otvgpos.c (otv_PairSet_validate): Set `extra3'.
(otv_PairPos_validate): Adjust.

[cff] Fix family name logic of pure CFF fontdata (#52056).
1. If `FamilyName' is present in the CFF font, use this for
FT_Face's `family_name'.
2. Otherwise, use the face name and chop off any subset prefix.
3. If at this point FT_Face's `family_name' is set, use this
together with the full name to determine the style.
4. Otherwise, use `CIDFontName' as FT_Face's `family_name'.
5. If we don't have a valid style, use "Regular".
Previously, FT_Face's `family_name' entry for pure CFF fontdata
nearly always was the fontname itself, instead of the `FamilyName'
entry in the CFF font (assuming there is one).
* src/cff/cffobjs.c (cff_face_init) [pure_cff]: Implement it.
2017-09-18 Alexei Podtelezhnikov <apodtele@gmail.com>
