Date: Subject: Some sample code for taking a screenshot in an OpenGL app: <p> First, let us add a Image method to help: <pre> Image grabScreen := method( data := Sequence clone width := glutGet(GLUT_WINDOW_WIDTH) height := glutGet(GLUT_WINDOW_HEIGHT) glReadPixels(0, 0, width, height, GL_RGBA, GL_UNSIGNED_BYTE, data) self setDataWidthHeightComponentCount(data, width, height, 4) self flipY ) </pre> Now we can use it (within a running GL application): <pre> Image clone grabScreen save("screenshot.jpg") </pre> Password:
