Example

 
 
- img = ia.open(’hcn’)  
- imcs=ia.coordsys()  
- blc = [’16:28:25.50’,  ’+040.49.05.61’]  
- trc = [’16:24:28.67’, ’+041.45.28.43’]  
- r1 = rg.wbox(blc=blc,trc=trc,pixelaxes=[0,1],csys=imcs.torecord())  
- rg.tofile(’myboxregion’, r1)  
- r1readback=rg.fromfiletorecord(’myboxregion’)  
 
 
In this example we create a box region using world coordinates for blc and trc. We save that on disk in a file called {\tt ’myboxregion’}.  
Then we read it back using the function rg.fromfiletorecord and store it in a variable {\tt r1readback}. {\tt r1} and {\tt r1readback} should be  
identical.
