Sorry, my misreading, the docs.
The docs are correct, but easy to misread if not careful. The ''<",
is supposed to work if you want to expand an image, not reduce it, to
my knowledge.
If you want to reduce the image, use ">" or ">^" depending upon
whether you want to reduce according to the larger or the smaller
image dimension and keep the aspect ratio preserved.
The docs says:
widthxheight<
Change dimensions only if both specified dimensions (meaning
WIDTHxHEIGHT) exceed image dimensions.
This means that it only changes the image dimension to expand to
WIDTHxHEIGHT if WIDTHxHEIGHT are both larger than the input image
dimension.
