the only way to implement it at clean way:

decode full image to Wi*Hi size (i=input).
copy/resize the Wc*Hc (c=crop) area to a new Wo*Ho (o=out) buffer and
call the encoder codec with this buffer. additional colorspace conversion
can be done at this copy/scale step.

if you want, i can implement it in a few minutes.

btw we should allow enlarging image without scaling too.
i mean adding black borders/bands over the image.
maybe usefull for something :)
