perfect. Lossless transforms operate on iMCUs, the size of which depends
on the level of chrominance subsampling used. If the image's width or
height is not evenly divisible by the iMCU size (see <a href="TJ.html#getMCUWidth(int)"><code>TJ.getMCUWidth()</code></a> and <a href="TJ.html#getMCUHeight(int)"><code>TJ.getMCUHeight()</code></a>), then
there will be partial iMCUs on the right and/or bottom edges. It is not
possible to move these partial iMCUs 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 iMCUs that cannot be transformed will be
left in place, which will create odd-looking strips on the right or bottom
edge of the image.</div>
