Hi, have you tried using read-bitmap? https://docs.racket-lang.org/draw/Drawing_Functions.html?q=read-bitmap#%28def._%28%28lib._racket%2Fdraw..rkt%29._read-bitmap%29%29
Personally I have only used the second constructor that takes a parameter named "in" here: https://docs.racket-lang.org/draw/bitmap_.html I didn't notice any performance problems, but my images have much lower resolution. I resize my images by using the bitmap function which returns a pict, then using scale-to-fit, then using pict->bitmap to convert back to a bitmap. Hope that is helpful, otherwise you could provide an example that I can test on my computer, I am on linux. Good luck!
