Robby and Matt,
I found one could very easily use the pict library to create bitmaps and
disseminate over HTTP as png-encoded binary streams
Which is really quite nice.
Thanks much for your work. The 2006 paper is very clear.
Recursively defined picts structures are powerful abstractions
;STEP 1: Convert PICT to Bitmap
(define x (pict->bitmap (cloud 100 50)))
;STEP 2: convert bitmap to png bytes. and base 64-encode them
(define png (base64-encode (convert x 'png-bytes)))
;STEP 3: send bytes across network
(printf "<html><body><img src='data:image/png;base64,\n
~A' alt='png failed to display' /></body></html>" png)
R./
Zack
