The Hatching engine simulates a hatching effect that is common with line drawings. This is commonly used when grayscale values cannot be used while printing—saving money. The pressure you apply sometimes makes your result darker, while other times (like the third example) it will make the brush larger. Some brushes give results more like sketching, while others give results more like applying screen tones.
A few different hatching styles and effects
Here we will find options to control how the hatching will appear as the stroke gets darker. You can also offset the hatching positions by changing the origin x and origin y values.
Once your strokes become dark enough on the canvas, your hatching will turn into crosshatching. This will make the result be more filled in. These are the crosshatching effects that you can add.
