Displaying bitmaps in DrRacket using 2htdp/image is near instantaneous when (display)-ed, but takes quite a while when shown as a result.
The effect gets very bad when lots of images are combined with (beside) and (above), while (display)-ing remains fast. Racket version is 6.5. Dan Sample comparison: displayln: 1 milliseconds result: 714 milliseconds Code: #lang racket (require 2htdp/image) (define harpos (bitmap/url " http://3.bp.blogspot.com/-_PE5YujeDKk/VcP3vpTgJZI/AAAAAAAAGpE/97T8sdMj6CE/s640/harpo-tryptych.png ")) (define a (current-milliseconds)) (displayln harpos) (define b (current-milliseconds)) (~a "displayln: " (- b a) " milliseconds") (define c (current-milliseconds)) harpos (define d (current-milliseconds)) (~a "result: " (- d c) " milliseconds") -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
