ADD/SUB/DIV/MULT - Image/image arithmetic

These programs perform the basic arithmetic operations on images, in all cases producing an image of the same type and shape as the two input images. They will operate on Integer*2, Integer*4 and Real*4 images.

ADD has been updated to correctly handle U*2 data (unsigned Integer*2) with additional facilities to clip or scale data in the event of overflows. Help is available for most of these programs by typing ? in response to prompts.

Parameters

Each requires three, the first input image, the second input image and the output image, If omitted they will be prompted for.

Examples

Adam:> SUB R1 R10 T1

Notes

These programs regard Integer*2 data as being signed so must be used with care.
