convert

I'm trying to create thumbnails of JPG photos using ImageMagick's convert tool. The thumbnails need to have a defined size (210x159), no blank areas, and the image can be cropped if necessary.

Unfortunately, I only have ImageMagick 6.3.7 available, which doesn't support the '^' geometry modifier (added in v6.3.8-3). Is there another way to achieve this in earlier versions of ImageMagick?

Thanks in advance.
