2000.07.17 14:13 "TIFF: G4 Height multiplication", by Chris Losinger
(using LibTiff 3.4 b37)
I have a g4 TIFF here that claims to be 1728 x 1055 pixels (this shows up in the tif->tif_dir.imagewidth and tif->tif_dir.imageheight as well as tile width and height. also, 1055 is the td_rowsperstrip value and td_stripsperimage is 1.
all of this tells me that the image is 1728 x 1055.
but, most image viewers draw this as 1728 x 2110; height doubled. and, the image looks correct with the doubled height.
the problem is that i don't see anything obvious in the tif_dir that tells me to double the height. nor do i see anyuthing in The Gimp or ImageMagick's TIFF reading code that would do this kind of doubling either.
can anyone help me out?
