Re: Ebcdic2ascii

Actually I also have some other problems like this one:

written += TIFFWriteFile(output, (tdata_t) "a PDF tag/r", 10);

this statements is executed hundreds of times, but sometimes it writes
garbage.

I've changed with something like:

strcpy(buffer, "a PDF tag/r");
written += TIFFWriteFile(output, (tdata_t) buffer, 10);

and it works always.

At this point I will check if I missed some PTF.

Beppe.
