I believe the documentation is in error! The ''<", is supposed to work if you want to expand an image, not reduce it, to my knowledge.
The docs says: widthxheight< Change dimensions only if both specified dimensions exceed image dimensions. but should say widthxheight< Change dimensions only if both specified dimensions DO NOT exceed image dimensions. Lanczos is probably best for minimizing. Anthony believes Mitchell is better for maximizing.
