Hi,
I'm trying to use these two geometry parameters:

width Width given, height automagically selected to preserve aspect ratio.
xheight Height given, width automagically selected to preserve aspect ratio.

But when I try both of them, I get the same results. Here is some sample output:
I expected the dimensions of the 300.png image to be 300x480. Am I doing something wrong? Am I misinterpreting the documentation quoted above?

Thanks for any insight on this!

It works for me on IM 6.6.0-4 Q16 Mac OSX Tiger

# create 400x640 image from IM internal image logo:
convert logo: -rotate 90 -crop 400x640+0+0 +repage logo_r90.png
identify logo_r90.png
logo_r90.png PNG 400x640 400x640+0+0 8-bit DirectClass 85.3KB 0.020u 0:00.019

# resize height to 300
convert logo_r90.png -resize x300 logo_r90_x300.png
identify logo_r90_x300.png
logo_r90_x300.png PNG 188x300 188x300+0+0 8-bit DirectClass 32.4KB 0.000u 0:00.010

# resize width to 300
convert logo_r90.png -resize 300x logo_r90_300x.png
identify logo_r90_300x.png
logo_r90_300x.png PNG 300x480 300x480+0+0 8-bit DirectClass 69.5KB 0.010u 0:00.019

# resize width to 300
convert logo_r90.png -resize 300 logo_r90_300.png
identify logo_r90_300.png
logo_r90_300.png PNG 300x480 300x480+0+0 8-bit DirectClass 69.5KB 0.010u 0:00.020

What version of IM are you using? Perhaps you need to upgrade!

convert -version

Note also:

-resize 300x300 will resize the largest dimension of the image to 300 and scale the smaller to preserve aspect ratio of the input

-resize "300x300^" will resize the smallest dimension of the image to 300 and scale the larger to preserve aspect ratio of the input

Thanks for the quick reply and sanity check. It turns out that there was *ahem* a different implementation installed on this machine. Once I switched it out for ImageMagick, it works fine.
