Subject: Re: Load TIFF in EPS files?
In reply to: neural 's message, "Load TIFF in EPS files?" on 03:09:51 01/18/02 Fri


Could you send me the EPS file. In version 2 there will an EPS graphic for EPS files that have a tiff preview.

I will try it out with my version.

Some exceptions are normal; ie, they get handled by Envision, so you may want to turn off "break on exception" in the debugger options. But I am not sure exactly what is the problem with your file.

Best regards,
