spd_ui_draw_object method: getZoom This routine returns the current zoom of the destination object Used primarily for determining scaling values to be applied to text when drawn. IDL doesn't properly correct for zoom, unless an object is already rendered. If you initially draw while at non 1. zoom text will be mis-sized unless scaled by zoom factor. Doesn't really apply to non-IDLgrWindow, because they don't have associated zoom factors. $LastChangedBy: jimm $ $LastChangedDate: 2014-02-11 10:54:32 -0800 (Tue, 11 Feb 2014) $ $LastChangedRevision: 14326 $ $URL: svn+ssh://thmsvn@ambrosia.ssl.berkeley.edu/repos/spdsoft/trunk/spedas/gui/display/draw_object/spd_ui_draw_object__getzoom.pro $
