Hi Matt,<br><br>Thanks for the suggestions. I tried your suggestion below:<br><span style="background-color: rgb(255, 102, 102);">Cropping can be done interactively with OpenEV, see</span><br style="background-color: rgb(255, 102, 102);">

/Main/ClipRasterWithoutArcInfo for an example.</blockquote><br>I followed all your steps and it ran the translation but when I opened up the translated file it still is the entire image not the cropped image that I outlined.
