'Jpeg Lossless Multi-conversion' works by rearranging the compressed data
(DCT coefficients), without ever fully decoding the image. Therefore, its
transformations are lossless, there is no image degradation.
'Jpeg Lossless Multi-conversion' operate rather oddly if the image dimensions
are not a multiple of the iMCU size (16 pixels), because they can only
transform complete blocks of DCT coefficient data in the desired way.
If the image dimensions are not a multiple of 16 pixels,SPM drops non-transformable edge blocks.
If left and right image size are different,SPM crops to same size (smaller one).
