I want to extract tiles from an image. E.g., I have a square

128x128+128+0
128x128+0+128
128x128+128+128
to obtain four tiles.
Applying this to the
convert -extract gave me 4 same looking resized pictures of the
whole image.
Did you just try convert -crop 128x128? That sounds like it's what you
really want.

Yeah, thanks. That's what I tried then next and it worked out fine. I
think though,
that the resulting images had a bounding box around being that of the
original image and I could't help other than reading the gifs once into
"xv" (my second favorite image manipulation program, under Unix, though).
There's probably be a way under IM to strip off that bounding box, too.
