Expand description

A trait implemented by types upon which can be drawn.

It is recommended to use the corresponding methods of Context instead of calling the methods of this trait directly.

Required methods

Draws the texture onto self.

Sets each pixel of self to color.

Resets the depth buffer of self to 1.0.

Draws a line from from to to.

Draws the bounding box of an axis-aligned rectangle specified by its lower_left and upper_right corner.

In case lower_left is to the right or above upper_right, the two points will be flipped.

Returns the current state of the DrawTarget.

For the window surface, this is a simple screenshot.
