[magick-users] Minimum dimension on resize?

[Chris Miller]

Hi,

I'm new to Image Magick.  I'm hoping it can do something I'm currently doing with another technology, but so far I haven't found the right parameters.  What I want is to resize an image by supplying the minimum of the two dimensions.  For example, I want to supply "480" and if the image is a vertical portrait, I want it to end up 480 wide by whatever height it was (probably 640).  However, if it was a landscape image, I want the HEIGHT to end up 480, for an image that is 640x480.

So, I want to say "resize the smaller of the two dimensions to the size I specify, and keep the aspect ratio the same".

Can I do that?
