Image Coordinates
I have taken an image with a ruler in it. I currently have the image showing with axis in pixels and require to have the axis in measurment units eg mm . I know there are 78 pixels per cm. If possible i would like the array axis to show real measurements aswell
any help on the issue would be much appreciated
Chris

If you called IMAGE or IMAGESC with one input, instead call it with three.
HELP IMAGE describes what the X and Y inputs represent; the last input will
be your image data.

Ok have taken a look at the help file but still not quite getting it is there a way to just scale my axis then just relocate 0,0 to different point on the picture ?
