Not using Shoes, but here is a code fragment using rmagick that has
worked for me (the tifs are gziped to save space on disk)
Zlib::GzipReader.open("imagefiles/" + fname + ".tif.gz"){|gz|
gzb = gz.read
izb = ImageList.new
izb.from_blob(gzb)
tcat = izb[0].crop(440,367,4565,1520)
tcat.write(fname +".tif")
}
The image is in memory (gzb) and is put into an ImageList with the
from_blob method. It can then be manipulated and written back out or
displayed (in a separate window..)
