OK, so what I did was:
for each image in the presentation:
select it
File->Export
select location (it doesn't store this? *%$@)
change type to "BMP" (this either? Double *%$@)
rename
OK
for each image I exported:
find width to remove (xv, crop, magnify, count)
bmptoppm $image (| pnmcut <parameters> if necessary) | cjpeg <parameters> > destination.jpg
PITA; JPEGs in the first place would have been much easier.
