Expand description
The canvas object acts as a wrapper around a buffer, providing information and functions for drawing
Fields
buffer: &'a mut [u8]
A buffer for the canvas to draw to
width: usize
The width in pixels of the canvas
height: usize
The height in pixels of the canvas
stride: usize
The number of bytes between each line of pixels on the canvas
pixel_size: usize
The number of bytes contained in each pixel
