Hi Ewald, I agree with your conclusion about number formats. Except for the 32000 (not 32768) issue, Type 1 and CFF should be the same.
I'm sorry that I don't know enough about Type 1 fonts to answer your other questions. I had never heard of the "postscript stack" before you asked, and I don't have any test fonts for it. It appears that Type 1 interpreters outside of an actual PostScript environment can make simplifying assumptions. -Dave On 6/21/2017 7:56 PM, Ewald Hew wrote:
On the other hand, this means there should be no other issues with number format between Type 1 or CFF ops, as long as the operands are pushed correctly as above. Do correct me if I'm wrong. Ewald. .
