Hello,
There is a 'self halt' in the code of TTFontReader
processCompositeGlyph:contours:from:. Therefore, when I try to import a font from a file, for example by evaluating:
TTFontDescription addFromTTFile: FileDirectory default fullName, '/Fonts/DejaVu/DejaVuSans-Bold.ttf'
the execution is stoped by this halt (And I don't know why). Now, when I remove the 'self halt', all seems to work correctly.
The halt is in
((flags bitAnd: 2) = 2) ifFalse:[self halt].
From the spec at http://www.microsoft.com/typography/otspec/glyf.htm , under Composite Glyph Description the flags are described : * * ARGS_ARE_XY_VALUES1If this is set, the arguments are xy values; otherwise, they are points. So, it's probably an indication that reading the values as points is not supported.
great. In such case we should write: ((flags bitAnd: 2) = 2) ifFalse:[self error: 'Reading the values as points is not supported']. :) Cheers Mariano
Cheers, Henry
