- shp := im.shape()                        # Shape of image
#
- p := imageprofilesupport(csys=csys, shp=shp, widgetset=dws)  
- p.setprofileaxis(axis);
- p.makemenus()
- pos := csys.referencepixel()             # Position in image
- p.makeabcissa(pos)                       # Generate abcissa along profile axis
- abc := p.getabcissa()
