beginFrame :: Context -> CInt -> CInt -> Float -> IO () Source #

Begin drawing a new frame

Calls to nanovg drawing API should be wrapped in beginFrame & endFrame.

beginFrame defines the size of the window to render to in relation currently set viewport (i.e. glViewport on GL backends). Device pixel ration allows to control the rendering on Hi-DPI devices.

For example, GLFW returns two dimension for an opened window: window size and frame buffer size. In that case you would set windowWidth/Height to the window size devicePixelRatio to: frameBufferWidth / windowWidth.

cancelFrame :: Context -> IO () Source #

Cancels drawing the current frame.

endFrame :: Context -> IO () Source #

Ends drawing flushing remaining render state.
