halt in TTFontReader >>processCompositeGlyph:contours:from:

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_VALUES

1

If 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.

Cheers,

Henry
