[−]Struct graphics::Viewport
Stores viewport information.
Fields
rect: [i32; 4]
Viewport in pixels.
[x, y, width height]
where (x, y)
is lower left corner.
draw_size: [u32; 2]
The size of frame buffer in pixels.
window_size: [f64; 2]
The size of window in points.
Methods
impl Viewport
pub fn abs_transform<T>(&self) -> [[T; 3]; 2] where
T: Float,
T: Float,
Computes absolute transform for 2D graphics, which uses a row major 2x3 matrix. The origin is in the upper left corner of the viewport rectangle. The x axis points to the right, and the y axis points down. The units are in points (window coordinates).
It is assumed that the underlying coordinate system is normalized
with the origin in the center, such that (-1.0, 1.0)
in the
underlying coordinate system corresponds to the
upper left corner of the viewport.
