Expand description
Helpers for drawing basic shapes on images.
Every draw_
function comes in two variants: one creates a new copy of the input image, one modifies the image in place.
The latter is more memory efficient, but you lose the original image.
Structs
A canvas that blends pixels when drawing.
Iterates over the coordinates in a line segment using Bresenham’s line drawing algorithm.
Iterates over the image pixels in a line segment using Bresenham’s line drawing algorithm.
Iterates over the image pixels in a line segment using Bresenham’s line drawing algorithm.
Traits
A surface for drawing on - many drawing functions in this
library are generic over a Canvas
to allow the user to
configure e.g. whether to use blending.
