[plt-scheme] bitmap pickles

Examining the contents of saved definitions into which I had pasted an 
image, I see that the image is stored in some kind of ASCII-ized PNG 
form, which is significantly more efficient than storing the pixels 
obtained from get-argb-pixels.

How is this done, and how can I use this technique in my programs?
