I vaguely recall someone describing how it is possible to create a small PImage and apply regular Processing code to draw in that image (instead of the screen) ... and later that image could be displayed on the screen, saved to a file, etc.

However, I haven't been able to track down the magical incantation to set that up.

I would really appreciate it if someone post a short example, or provide a link to a previous discussion on this topic.

In my sketch, I want to create a bunch of small PImages, draw some text into those images, and then during the animation, ... display those PImages at different locations on the screen.  I am partly doing this because the "text" functions seem particularly slow and I can't achieve the desired frameRate.
I want to render the text ahead of time, and then use a fast image copy for each frame.

thanks!
