When trying to apply diagonal hints to a regular (non italic) sans serif style font (i.e. Arial, Gill Sans, Univers) glyph (upper case V) using the Stroke function within the main window I receive the following error (with grid-fit on):
"Glyph ID 36
Critical Error: Int: CALL Function not defined. Function = 20 At ByteOffset: 42"
Glyph ID 36 is upper case V in my instance and function 20 in the Glyph Program window is :
"CALL [], 2, 76, 5, 4, 20"
The 2, 5, and 4 are point numbers within the glyph which are receiving the diagonal hint and the 76 is my CVT Diagonal StraightStroke number. If the '20' is also a reference to the CVT then that would point to UpperCase X ItalicRun in which I filled in as 290. The Pre-Program has no function 20 calls nor does the Font Program.
If I manually input the Stroke command in the VTT talk window I receive the same error.
If I manually input the DStroke command in the VTT talk window I receive the same type of error but with slightly different parameters:
"Glyph ID 36
Critical Error: Int: CALL Function not defined. Function = 66 At ByteOffset: 35"
Once again, if function '66' is a CVT reference then there is a value stored there. Likewise, there is a CALL 66 listed in the Pre-Program too.
Admittingly, this is my maiden voyage with hinting and the use of Visual Truetype so perhaps I'm missing something or forgot to fill in a value somewhere...
