Line Texture

The Normal Brush Mode creates contour lines as you draw, adding each brush lines on top of the last ones.

Draw Behind

When the Draw Behind mode is enabled, the lines you draw will appear behind the art that already exists.

Repaint Brush Mode

The Repaint Brush is used to repaint zones that have already been painted, it will not affect empty zones or pencil lines. It also automatically flattens each of its brush lines so it does not add new brush lines on top of existing ones. You can use this mode to paint tones or highlights onto your character.

Create Colour Art Automatically

As you draw in the Line Art layer, the Create Colour Art Automatically automatically creates the corresponding strokes in the Colour Art layer.

Auto-Flatten Mode

When enabled, the Auto-Flatten mode automatically flattens the new lines created with the existing artwork as you draw in the Drawing or Camera view. Brush strokes will flatten with brush strokes and pencil lines will flatten with pencil lines.

Respect Protected Colour

The Respect Protected Colour option prevent the colours you marked as protected in the Colour view to be repainted using the Repaint Brush mode or any of the painting tools.

Refer to Protecting Colours to learn how to use the Protect Colour feature.

Use Stored Colour Gradient

The Use Stored Colour Gradient option makes your tool use the previously stored gradient position. This way, every new brush line or colour fill will use the stored gradient position.

Refer to Storing Your Favourite Gradient or Texture Settings to learn how to use the Store Colour Gradient option.

Drawing Magnifier

The Drawing Magnifier tool allows you to magnify portions of your drawing. When this option is enabled, you can hover over your drawings to see a close up of your lines in the Magnifier box.

This feature only works in the Drawing view.

Dynamic Brush

A Dynamic Brush can be created to allow you to draw using patterns created from your artwork—see Dynamic Brush

Minimum and Maximum Size

This is where you set the minimum and maximum sizes of your drawing tool which will produce the thick and thin effect on your stroke. This works with the pressure sensitivity of a pen tablet.

2. Maximum Size field: Type a value in this field to set the maximum width of the line.

Contour Optimization

You can optimize the Contour Line Smoothness of you line using this option. This parameter will smooth the contour of your line once the line has been traced, the higher the value the less control points will compose your line.

1. Smoothness field: Type a value to set the smoothness of the line.
2. Contour Optimization field: Type a value to set the contour optimization of the line.

Line Texture

In Toon Boom Harmony, you can draw with a textured line. Textured lines are a mixed bitmap image contained in a vector frame. This allows you to sketch as if you are drawing on paper.

Refer to the Drawing with Line Texture topic to learn everything about line texture and its parameters.
