frankie January 26, 2017, at 11:12 AM: This has been added. Syntax is similar to speedtest, although it is done on a creation or configuration of a canvas. For example, for a canvas called "cw_canvas" you could use the following to disable the red channel:

cw_canvas configure -rgb_gain 0.0 1.0 1.0

Similarly, to query the canvas for the current gains, run the same command without the arguments present:

set current_rgb_gain [cw_canvas configure -rgb_gain]

You can change the gains as follows: <canvas_name> configure -rgb_gain 0.0 1.0 1.0 The above name would disable the red channel for that canvas. Similarly, running without the 3 numerical arugments will return the rgb_gain for that canvas. @] |
