Context creation configuration

A Conf struct is used to describe a hardware and platform specific setup, mostly video display settings.

§High DPI rendering

You can set the Conf::high_dpi flag during initialization to request a full-resolution framebuffer on HighDPI displays. The default behaviour is high_dpi = false, this means that the application will render to a lower-resolution framebuffer on HighDPI displays and the rendered content will be upscaled by the window system composer. In a HighDPI scenario, you still request the same window size during miniquad::start, but the framebuffer sizes returned by Context::screen_size will be scaled up according to the DPI scaling ratio. You can also get a DPI scaling factor with the function Context::dpi_scale. Here’s an example on a Mac with Retina display:

ⓘ
Conf {
  width = 640,
  height = 480,
  high_dpi = true,
  .. Default::default()
};

The functions screen_size and dpi_scale will return the following values:

screen_size -> (1280, 960)
dpi_scale   -> 2.0

If the high_dpi flag is false, or you’re not running on a Retina display, the values would be:

screen_size -> (640, 480)
dpi_scale   -> 1.0
