How to draw image faster
yijia last edited by
I'm drawing some images on a widget inherited from QOpenGLWidget, and it shows properly.But on some computers it doesn't show anything. I used OpenGL Extensions Viewer and it told me the opengl version is 1.0.0. Maybe the graphics card is too old to support opengl. So I used drawPixmap instead of opengl functions, which is available but slow.
My question is: Is there a way I can draw image faster without opengl ?I'm considering ANGLE, but I know little about it and dont't know how to start.
