perfect. Lossless transforms operate on MCU blocks, whose size depends on
the level of chrominance subsampling used. If the image's width or height
is not evenly divisible by the MCU block size (see <A HREF="../../../org/libjpegturbo/turbojpeg/TJ.html#getMCUWidth(int)"><CODE>TJ.getMCUWidth(int)</CODE></A>

right and/or bottom edges. It is not possible to move these partial MCU
blocks to the top or left of the image, so any transform that would
require that is "imperfect." If this option is not specified, then any
partial MCU blocks that cannot be transformed will be left in place, which
will create odd-looking strips on the right or bottom edge of the image.
