Probably convert is best while caching pixels to disk to conserve memory. It will be slow but dependable: convert -limit area 1mb *.tif new.tif If you want to append to a single image: convert -limit area 1mb *.tif -append new.tif Stream is only useful if you want to extract a small area from a huge image. Support you have a 100000x100000 TIFF image but you only want to extract a 2048x2048 area from the image, use the stream program. With convert you can do something similar. Assume you want the top half of each 10000x10000 pixel image: convert -limit area 1mb '*.tif[10000x5000]' new.tif Instead of reading the entire image sequence, it reads one TIFF image at a time, extracts the top half and moves to the next image. ImageMagick is not very effient with 1 bit images. You might get some speed-up if you use the Q8 version of ImageMagick. The default build is Q16, or 16-bits per pixel. _______________________________________________ Magick-users mailing list [email protected] http://studio.imagemagick.org/mailman/listinfo/magick-users
