718201471a {subset,builder}_test: fix order of fromfile/tofile in expect_ttx 
The order of the arguments for difflib.unified_diff was inverted in feaLib.builder_test.
The same snippet was probably copy-pasted to the subset_test.

ddfa48ea7c subset: 'draw' charstrings to set 'width' before calling 'drop_hints' 
the horizontal advance of hinted charstrings gets lost when the CFF hinting
is stripped with '--no-hinting' option, as noted by @miguelsousa here:

https://github.com/behdad/fonttools/issues/343#issuecomment-156234918

The reason is T2CharString objects only get assigned a 'witdh' attribute
after their 'draw' method is called.

The subsetter's 'drop_hints' function attempts to insert the width back
at the beginning of the de-hinted charstring's program, but can do that
only if the charstring does have a 'width' attribute:

5b479716bc Fix bugs in cffLib.py. 1) In the last commit, I added logic to use a CFF predefined charset when possible. This is not allowed In CID fonts. Added a test to NOT do this when font is CD. 2) Added exception handler when reading FontDict XML to skip unknown fields. In previous versions, all the default key/value pairs for the TopDict were (incorrectly) written to FDArray FontDicts. New logic does not do that, but also should not fail when it sees any of these key/value pairs. 3) Changed the expected txt files for some of the subset tests. For the CID example, this meant removing the unnecessary key/value pairs from the FDArray FontDicts. For all, it meant adding the major.minor CFF version fields. 2016-09-27 19:49:41 +02:00

402d726692 [ot] Change Version to be an integer instead of float 
API Change:
This will change XML output for GSUB/GPOS/GDEF/MATH/BASE/JSTF/...
Scripts that set the Version for those to 1.0 or other float values
also need fixing.  A warning is emitted when code or XML needs fix.

a41c60cb88 Fixed encoding error in subset tool in Windows 
Fixed encoding error in subset tool in Windows which system default codepage isn't 65001.
For Example: 
When windows default codepage is 936, the command like 'pyftsubset myfont.ttf --text-file=mytextfile.txt' will throw an exception.

7ac65613eb [subset] add --with-zopfli option; set 'canonical_order' to None 
'canonical_order' default value was set to False in the subsetter. However,
the meaning of the related 'reorderTables' argument in TTFont.save method has changed
with commit 6ba67ab699d62962690a7a523c286ebf0c8b0ae4.
When the latter is set to False, the original input font's table order is "kept": which
still means doing some sort of reordering. If one wishes to avoid any kind of reordering,
reorderTables needs to be set to None.

c5febaf1a5 [subset] remove custom Logger and use logging instead 
The Subsetter class now uses a module-level 'log', and no longer uses
its own custom Logger. This has been removed, and its features replaced
by equivalents.

log.lapse() are replaced with Timer context manager/decorator (these should make clearer where the elapsed time starts/stops);

log.glyphs() is kept for convenience: it is bound dynamically to the logger instance instead of subclassing logging.Logger, as it's only
useful in here.

log.font() is replaced by `font.saveXML(sys.stdout)`.

A distinct sub-logger is configured for timing messages, to allow --timing option to be enabled independently from --verbose

301d2db812 [subset] Support subsetting MS color tables 
Add support for subsetting COLR table.

The CPAL table does not need subsetting, but unused palettes should be
pruned, this is not implemented however as it depends on COLR table,
which in turn will not be updated after pruning CPAL.
