Hello,All.Now I encounter such a tough problem.I want to constantly draw a bitmap by a certain angle.If I choose to transfer the bitmap to image and rotate the image,that must be a hard work.So I consider to rotate the coordinate.But how can I rotate the coordinate by any angle.It seems that it is possible.How can I solve this tough project.It makes me crazy.Help!!
Anyone who has a good idea? I will appreciate that.Thanks

Look at wxGraphicsContext and it method SetTransform

Thanks bishop.gis .I will get a try.
