Hello, I'm writing a client in the C language which uses the libsane library. The basic idea, at the stage i'm in, is to write code to copy scanimage's behavior. It's supposed to get the scanned data and write it to stdout in tiff format. I'm having some troubles with the tiff header: i'm using stiff.c I found in the backends' package to write the header of the file. The problem I'm having is that the tiff file is practically malformed (test opening it with the gimp). So i hijacked the stiff library and put a fprintf and exit right after the header is created. Here's what i get for the same page from the original scanimage and my code:
< scanimage > width 5056 height 9000 depth 8 resolution 600 < my code > width 5399 height 9000 depth 8 resolution 600 doing a binary diff on the two headers i realize that (of course) they are different (same size though). I cannot really understand the problem as the stiff code is untouched and my code is practically equivalent to test.c My question is: why does my code get a different width than scanimage as we are both using data from sane_get_parameters()? I guess the problem will be solved in the moment i find an answer to this question. I'll send my code to those who request it (less than 200 lines). I'm using an HP LaserJet 3055 with hplip 1.6.9 on ubuntu edgy, sane 1.0.14. TIA Claudio Martella P.S.= for the moderator: I've sent a copy of this email with another address and should be waiting in your queue for acceptance. Please, drop it.
