I'll see if that works.
That worked. I lost some tag information and the process is a pain in the neck, but it worked. Command sequence on OS X: for i in $(jot $(tiffinfo array.tif | grep TIFF | wc -l) 0) ; do tiffutil -extract $i array.tif -out array.$i.tif # resize array.$i.tif with the gimp # save as array.$i.400x524.tif done tiffutil -cat array.*.400x524.tif -out array.400x524.tif To see the smaller two-page tiff: http://cwelug.org/~rwcitek/array.400x524.tif 400 x 524 = 0.42 MB 2738 x 3586 = 40.00 MB That's a sizable difference. BTW, the image is a scan from a two-color microarray scanner. The images are scans of a glass slide with literally thousands of dots of DNA. One image is the scan at one wavelength, while the other image is the scan of the exact same slide at a different wavelength.
