decker spirograph

Some things to try:

Change how it draws the spirograph:

Open the listener ( control-L or use the Decker -> listener menu ), then type:

spirograph.brush: 2

and hit shift-enter. that will change the brush being used to draw (there are lots of numbers you can try). Or go into the code and change the  line:

c.pattern: colors.blue  

to use a different color (try colors.red, or any number between 0 and 64)

Make it stamp the pattern to an underlying canvas:

• Add a second canvas widget (Tool -> Widget, then Widgets -> New Canvas)
• Move it below the spirograph with Edit -> Move to back.
• Make the spirograph transparent (Widgets -> Show Transparent)
• Add a button widget and have its script copy the image with: the code:

on click do
  img: spirograph.copy[]
  img: img.map[(38 dict 32}] # changes blue (38) to another color!
  canvas1.paste[img 0,0 1]   # the 1 makes it respect the transparency
end

you can use the listener to make sure the two canvases ovelap exactly:

canvas1.size:spirograph.size  canvas1.pos:spirograph.pos
