* varLib.cff: Apply conv_to_int() to all the values
* varLib: Don't hardcode file extension to 'ttf'
Also remove unused imports
* varLib.cff: Fix merging of sparse PrivateDict items
Fixes#1651
When building a variable font, varLib.build must make sure that
the OS/2.usWeightClass is equal to the wght axis default location,
that the OS/2.usWidthClass is set to the equivalent value (1-9) of
the wdth axis default location, and finally that post.italicAngle
is set to the same default value as slnt axis.
Sometimes the base master doesn't have these values correctly
set leading to discrepancies between OS/2 and post, on the one
hand, and the fvar axes' default values.
Fixes#1650
A regression was introduced with 3.43.0 when doing pyftsubset --flavor=woff2
and the input font is WOFF 1.0, thus it has a non-None flavorData already
but doesn't define the transformTables attribute.
isPairPos and isSinglePos are mutually exclusive and isSinglePos is only defined if isPairPos is False
so it is safe to use it in 'else' or 'elif' branches (logical expressions short-circuit)
- changed getCoordWidth method to use all if-stmt, ordered by ret value (0, 1, 2).
- added more info to TypeError message in getCoordWidth method.
- in round/scaleDeltas, chained if statements in one line to avoid writing the loop twice.
since we use pytest-randomly to randomize the test execution, depending on when
this specific test is executed, it may have the side effect of configuring
the global logging configuration, causing other tests that capture logging
messages to fail.
E.g. see https://travis-ci.org/fonttools/fonttools/jobs/545680550
When a SinglePost lookup is compiled, pretty much all compilers do some compression by combining similar ValueRecords into a single subtable. This compression produces different lengths of the list of subtables between source fonts. The original code required that all SinglePos lookups have the same subtables, often doesn't work.
I fixed this in varLib.merger.py by first flattening a SinglePos lookup to a single subtable, using the same record format for all records, and then merging the source fonts. After the merge is complete, I call fontTools.otlLib.builder.buildSinglePos() to rebuild the lookup subtables.
Also, the TTFont.getGlyphOrder() automatically makes up a dummy
glyph order from the maxp.numGlyphs, we simply need to ensure
'maxp' is decompiled before 'glyf'.
When transforming glyf, the glyf.glyphOrder is guaranteed to
be present (as the glyf table has been already decompiled), so
we don't need to deal with it being missing or incorrect
(hence removed spurious tests).
Previously we were calling glyf.setCoordinates method only when a glyph had some
variation deltas to be applied to the default glyf coordinates.
However, some composite glyph may contain no variation delta but their base glyphs
may change, thus we still need to update the sidebearings and bounding box of the
composite glyphs.
