imageprofilesupport.setcoordinatesystem - Function

	Package	general
	Module	images
	Tool	imageprofilesupport

Set a new coordinate system

Synopsis
setcoordinatesystem(csys, shp, resetref)

Arguments

csys	in	New coordinate system
		Allowed:	Coordsys tool
shp	in	Shape of associated image
		Allowed:	Vector of integer
resetref	in	Reset Reference Frame to Native of new Coordinate System
		Allowed:	T or F
		Default:	F

Returns
Integer or fail

Description

This function sets a new coordinate system and associated image shape. This function will update the x-axis menus appropriately.

After calling this function, you must remake the abcissa and ordinate profiles (functions makeabcissa and makeordinate or setordinate).

The argument resetref is used to reset any reference frame selection (in the GUI) back to the native one contained in the new coordinate system (or any extra frame conversion currently set in the supplied coordinate system). Otherwise, the GUI selection is left as it is. For example, the user might have asked to convert a Spectral coordinate to TOPO. If resetref=F TOPO is left selected and conversions are made to it. If resetref=T then, if the new coordinate system has LSRK say as the native frame, then LSRK is now selected in the GUI and no extra conversions are made.

Example

- im := image('ngc1313.cube')              
- csys := im.coordsys()                    
- shp := im.shape()                        
- axis := 3;
- p := imageprofilesupport(csys=csys, shp=shp)
- p.setprofileaxis(axis);
- p.makemenus()
- pos := csys.referencepixel()             
- p.makeabcissa(pos)                       
- r := drm.box()
- p.makeordinate(im, r)
- p.plot()                                 
-
- im2 := image('ngc1399.cube')              
- csys2 := im2.coordsys();
- shp2 :=  im2.shape();
- axis2 := 1;
- p.setprofileaxis(axis2)
- p.setcoordinatesystem(csys2, shp2)
- pos := csys.referencepixel()             
- p.makeabcissa(pos);
- p.makeordinate(im2, r)
- p.plot()
