## What is Line Art?

Extract image contours, outlines and edges and convert them to line art

Detect image outlines and convert to edge-detected images to create unique and artistic images.

It can also be used as a reference for manga, drawings, designs, etc.

You can change the black line on the white background and the white line on the black background.

I am using Canny edge detector

It is for those who want to process images easily without unnecessary functions.
