I'm drawing linesegments to reconstruct the waveform contained in a buffer.

Then I'd like to add, at some points, a background symbolising a selection.

I've done that using sprite, but the sprite is above the waveform, which means that I can't see what's going on in the selection...

The question is : Is there a way to tell [LCD] to draw above the sprite or to draw sprites in the background ?

I'm now using framerect and not paintrect, but it's not visually as interesting.

Maybe I could make a frame with all the linesegments, but it seems tricky...

try the frontsprite and backsprite messages

ex [..., closesprite background-foo, drawsprite background-foo 0 0,

backsprite background-foo]
hope that helps.

The problem is that the waveform isn't a sprite, but is drawn by a basic combination of [linesegment $1 $2 $3 $4 $5]

Here is a simplified version of the patch

The idea would be to change the content of [p draw] to turn it into a sprite. This seems pretty impossible... I don't know.

If you have any other idea to put the red selection behind the orange waveform, don't hesitate.

recordsprite, penmode 32, oprgb 128 128 128, paintrect $1 $2 $3 $4 $5, closesprite sel, drawsprite sel 0 0, backsprite sel

Sprites can be transparent. Try this:
recordsprite, penmode 32, oprgb 128 128 128, paintrect $1 $2 $3 $4 $5, closesprite sel, drawsprite sel 0 0, backsprite sel
