Example

- im := image('ngc1313.cube')              
- csys := im.coordsys()                    
- shp := im.shape()                        
- p := imageprofilesupport(csys=csys, shp=shp, widgetset=dws)  
- p.setprofileaxis(axis);
- p.makemenus()
- pos := csys.referencepixel()             
- p.makeabcissa(pos)                       
- r := drm.box()                           
- p.makeordinate (im, r)                   
- xy := p.getxy()
