++We also offer a lossless-crop option, which discards data outside a given
++image region but losslessly preserves what is inside.  Like the rotate and
++flip transforms, lossless crop is restricted by the JPEG format: the upper
++left corner of the selected region must fall on an iMCU boundary.  If this
++does not hold for the given crop parameters, we silently move the upper left
++corner up and/or left to make it so, simultaneously increasing the region
++dimensions to keep the lower right crop corner unchanged.  (Thus, the
++output image covers at least the requested region, but may cover more.)
++
++Note: lossless-crop is an enhancement from http://sylvana.net/jpegcrop/ 
++that may not be available on non-Debian systems.
++
++The image can be losslessly cropped by giving the switch:
++.TP
++.B \-crop WxH+X+Y
++Crop to a rectangular subarea of width W, height H starting at point X,Y.
++.PP
++.PP
+ Another not-strictly-lossless transformation switch is:
