Hello
i've experienced some problems with the display of a TIFF file that I have described in my previous mail in this mailing list. Even if this problem is solved, i would like to suggest 2 improvements:
1) Olivier Paquet mentioned that the man page of TIFFRGBAImageGet() says:
"(Note that the raster is assume to be organized such that the pixel
at location (x,y) is raster[y*width+x]; with the raster origin in the
lower-left hand corner.)"
This comment, which is imho important, is lost in a big paragraph. Maybe you should use a bold font to emphasize this comment and/or add it to the "Note" section
2) to solve my problem, i have followed Mickey Rose's suggestion:
"
After you intiialize the TIFFRGBAImage structure with TIFFRGBAImageBegin, set img->req_orientation = ORIENTATION_TOPLEFT (it defaults to BOTLEFT).
TIFFRGBAImageGet will then output the top row first."
I think that such comment should be in the libtiff documentation (http://simplesystems.org/libtiff/libtiff.html)
best regards
