Hello Jacob,
This is a documented behaviour. Please read the manpage:
The transpose transformation has no restrictions regarding image
dimensions. The other transformations operate rather oddly if
the image dimensions are not a multiple of the iMCU size (usu�
ally 8 or 16 pixels), because they can only transform complete
blocks of DCT coefficient data in the desired way.
However your image is 612 x 501. I suggest you consider using the options -trim
or -perfect.
Cheers,
