Draw pixel from script

Hello,

I'd like to find a way to manipulate pixels on the LCD from script.  I've tried building CHDK with a new uBasic command "draw_pixel", which calls the draw_pixel() function, however this has met with no success.  A script using the command will run, but no pixels are changed on-screen.

Thanks,

Peter

The drawing should probably happen in the spytask task which draws most of the rest of the CHDK gui, and be repeated on each re-draw as long as you want the pixel to be visible. So I would suggest that the script commands built up a list of things to draw, and some code in the gui actually takes care of drawing them.

Scripts run in the kbd (aka physw) task.
