Re: [racket-users] How to fill a shape with a texture using 2htdp/image or similar?
Maybe there are other useful pict/brush modifiers of interest? https://github.com/soegaard/metapict/blob/master/metapict/pict.rkt#L149 /Jens Axel 2015-05-21 18:41 GMT+02:00 Robby Findler ro...@eecs.northwestern.edu: Oh, nice!

Re: [racket-users] How to fill a shape with a texture using 2htdp/image or similar?
Yes, indeed. All those functions right there feel like they belong in the generic pict library, not in the meta-pict layer on top.
