By default, convert will respect PageMediaDimensions but will ignore PageMediaCropRect.

This results in a PDF that appears to be portrait actually export as landscape with extra white space (or similar).

Adding the "-page letter" flag to the convert command can address this when the page size is obvious (confirmed), but that is not technically accurate. A better solution would be to extract the crop values and apply them within the convert command using "-crop ...".
