Does the customer's font file(s) (PFM + PFB, or suitcase + outline font) work
with ATM? Or is the Type 1 font in question autogenerated? For instance, on a
PC platform, the print drivers could be making (depending on how the driver is
configured) a Type 1 font out of a TT font (resulting in non-integer bboxes),
and these non-int bboxes are getting passed through to the PDF file when the PS
file is distilled.
If the Type 1 font is not autogenerated and works with ATM, we ought to add real
number parsing to the Type 1 driver's font bbox parsing code.
If the font is autogenerated, we have no way of really testing it with ATM, so
I am guessing in this case that Acrobat Reader (which uses CoolType, right?)
has more robust font bbox parsing. Perhaps I could make a test suitcase and
outline file (using TransType from FontLab) and try that with ATM. That would
help in testing. I guess I need to see the PS file (was this made with one
of Digital Applications products?) and the original PDF file.
