How to define a size 320x480 for intermediate pictures using IM

[leemax]

Like the Topic, I hope the intermediate pictures not just resize to Max width or height,
but "Command line options for ImageMagick" can control thumb only.

I do not understand what your question is.

sorry, I make a wrong.
this is my site : http://www.tootoo8.com
a iPhone wallpaper site, user can upload pictures. But the size(pixel) not fit the iphone wallpaper size(320X480px)

so I open "Create intermediate pictures" option and at "Command line options for ImageMagick"  add " -gravity center  -crop 320x480+0+0"
and then I solved the prolblem: create 320X480px intermediate pictures.

But, originally, I used the "Command line options for ImageMagick"  add " -gravity center  -crop 62x62+0+0" to create the thumbnails by 62X62px size.
Now, I open "Create intermediate pictures" option, how can I creat 62X62px thembnail?

The commandline option are valid for all resized images. It doesn't matter if they are intermediate images or thumbs.
The modpack contains a cropping function just for the thumb. But I think with some coding you could enhance it to crop intermediates as well...
