This project is part of the @thi.ng/umbrella monorepo.

About

2D shape drawing & rasterization.

The functions in this package can be used with any IGrid2D compatible grid/image type (e.g. those provided by @thi.ng/pixel or @thi.ng/text-canvas).

Currently the following functions are available:

Circle

Filled or outline implementation of Bresenham's circle algorithm. A clipping check is pre-applied to see if the circle lies entirely outside the target grid.

Line

Implementation of Bresenham's line algorithm with pre-applied Liang-Barsky clipping. The higher-order function drawLineWith() can be used to apply custom brushes to trace the line.

Rect

Filled or outline implementation with pre-applied clipping against the target grid.

Flood fill

Fills grid in the connected region around x,y with given value or pattern. See floodFill() in the @thi.ng/grid-iterators package for further details.

Status

ALPHA - bleeding edge / work-in-progress
