Light Switch Procedure Pict
This is a procedure picture suitable for jazzing up a check box. It describes a light switch with up/ON and down/OFF positions, with slightly darkened versions for mouse down and washed out low contrast versions for disabled. Modified from the light switch on the icon for OS X system preferences. Background grey has been adjusted to match background of default Igor control panel. I spent all blessed morning drawing this thing, so I hope people find it useful. And yes, I know that light switches in some places normally work the reverse of this way, with down being on and up being off.
Due to the fact that the code for the pictures contains all kinds of characters that are filtered out by the web site, code to recreate each of the three switch images is attached as an Igor Pro procedure file to this snippet.
