Hi Peter, You are supposed to use make-gl-bitmap to get a bitmap for which a gl context can be created.
Otherwise you may or may not get GL ability in your bitmap. Stephan On 09/22/2011 05:38 AM, Ivanyi Peter wrote:
Dear All, I am using Racket 5.1 on Windows. I have a program which renders an OpenGL image into a bitmap. The following used to work in PLT-Scheme. (define a (make-object bitmap% 100 100 #f)) (define b (new bitmap-dc% (bitmap a))) (send b get-gl-context) Now it returns #f. Is it a bug or feature? Is there any way that I can make it work again easily?
