1997.01.10 21:39 "TIFFOpen for appending", by Chuck Packard

Hi,

I am trying to put a TIFF into an existing EPS file to act as a preview. I read the man page for TIFFOpen and it says you can pass it a mode of "a" so that it appends:

     When a file is opened for appending, existing data
     will not be touched; instead new data will be written as
     additional subfiles

But I am getting the error '%s: Cannot open'; I have verified that I can call fopen and append to the file myself in place of the call to TIFFOpen. Is TIFFOpen expecting the file it is appending to to be another TIFF file? What is the 'subfile' it is talking about?

Thanks,
