Function fermium::renderer::SDL_RenderSetLogicalSize [−][src]
pub unsafe extern "C" fn SDL_RenderSetLogicalSize(
renderer: *mut SDL_Renderer,
w: c_int,
h: c_int
) -> c_int
Set device independent resolution for rendering
renderer
The renderer for which resolution should be set.w
The width of the logical resolutionh
The height of the logical resolution
This function uses the viewport and scaling functionality to allow a fixed logical resolution for rendering, regardless of the actual output resolution. If the actual output resolution doesn’t have the same aspect ratio the output rendering will be centered within the output display.
If the output display is a window, mouse events in the window will be filtered and scaled so they seem to arrive within the logical resolution.
If this function results in scaling or subpixel drawing by the rendering backend, it will be handled using the appropriate quality hints.
