Re: [ferret_users] question about window's aspect

["William S. Kessler" <William.S.Kessler@xxxxxxxx>]

The best way to control the aspect ratio is to define your own  
viewports, using the DEF VI/AXES syntax.

For example, suppose I want a viewport that is 33 units wide and 23  
units tall, and I want the space on the left to be 5 units, on the  
right 3, on the bottom 4, and the top 6:

let hor=`33+5+3`; let vert=`23+4+6`
set win/asp=`vert/hor`
def vi/axes/xli=`3/hor`,`36/hor`/yli=`4/vert`,`27/vert` newasp
set vi newasp

This kind of thing gets even more useful when you have multiple  
viewports.
