Draw a line

The Line Tool allows you to draw a two-point line on the canvas. Lines can be drawn as vector shapes, paths, or pixels. Choose Shape mode if you want to make a non-destructive, scalable line that you can edit at a later date. Choose Pixels mode when working with rasterized content such as pixel art.
