Eraser Tool Properties

When you select the Eraser tool, its properties and options appear in the Tool Properties view.

The Eraser tool properties are almost identical to the Brush tool properties.

NOTETo learn how to use the Eraser tool, see About the Eraser Tool.

Icon	Tool Name	Description
	Stroke Preview Area	The Preview area lets you see a preview of the stroke your drawing tool will make.
	Eraser Properties Dialog	The arrow button right of the display area opens the Eraser Properties dialog, which gives you access to all the parameters and options for your eraser. The Tool Properties view only gives you access to a few of the eraser properties, a list of eraser presets and options for the Eraser tool that are not related to the eraser properties. For more information on the Eraser Properties dialog, see the Eraser Tool Properties section below.
	Maximum Size	Defines the maximum size of the eraser. If the tool is used with a pressure sensitive pen tablet, the width of the stroke will vary between its maximum size and minimum size depending on the amount of pressure used. If used with a mouse, the width of the stroke will always be its maximum size.
	Smoothing	Defines the number of control points added to the centre line. The fewer the control points the smoother (but less faithful) the line.
	Flow	Lets you set the opacity for each instance of the eraser tip that gets erased from your artwork. Contrary to the Opacity parameter, the flow parameter has a cumulative effect. This means that a lower flow will make your eraser strokes less effective towards its extremities and more effective in its center. Your stroke's flow will also accumulate if you draw over it. By default, your eraser's flow varies with the amount of pressure you put on your tablet pen. NOTEThis option is only displayed in the Tool Properties view when drawing on a bitmap layer.
	Opacity	The Opacity parameter are where Lets you set the opacity of your brush strokes. Contrary to the Flow parameter, the Opacity parameter is non-cumulative. Your whole brush stroke's opacity will not exceed the Opacity parameter. By default, the Opacity parameter varies depending on the amount of pressure you put on your tablet pen. NOTEThis option is only displayed in the Tool Properties view when drawing on a bitmap layer.
	New Eraser	Creates a new preset based on the current eraser properties.
	Delete Eraser	Deletes the currently selected preset.
	Rename Eraser	Deletes the currently selected preset.
	Import Erasers	Allows you to import brush presets exported from Harmony.
	Export Erasers	Allows you to export your brush presets into an .xml file.
	Small Thumbnail, Large Thumbnail, and Stroke View	Allows you to display the presets as small square thumbnails, large square thumbnails or a list of stroke preview.

Eraser Properties Dialog

Erasers have an extensive set of options and properties that are not displayed in the Tool Properties view, but rather, in a dialog you can access from it. To open the Eraser Properties dialog, click on the arrow button right of the stroke display area.

Edit Brush To Add Texture

The Eraser Properties dialog has two tabs. Below is detailed information about the options available in each tab:

Tip Tab
Smoothing Tab

Tip Tab

The Tip tab allows you to configure the shape, size, hardness and spacing of your eraser tip.

Tool Name	Description
Eraser Tip Library	This is where you select the shape of the eraser tip. By default, it is round.
Minimum and Maximum Size	The minimum and maximum sizes of your drawing tool produce the thick and thin effect on your stroke. This works with the pressure sensitivity of a pen tablet. Maximum Size: Defines the maximum width of the stroke. Minimum Size: Defines the minimum width of the stroke in relation to and as a percentage of the maximum size. NOTESetting the Minimum Size value to 100% eliminates the possibility of creating width variation on your stroke. In other words, you would be forcing a uniform line width using the Maximum Size value.
Roundness and Angle	The Roundness and Angle parameters allow you to change the shape and orientation of the tip. Roundness: Squashes the height of the tip from its centre point. 100% roundness = the native height of the tip. A smaller percentage will make the brush tip look flatter and more narrow. The squashing is NOT relative to the angle value—if the tip is rotated, the squashing function still uses the brush tip's original orientation. Angle: Rotates the brush tip counter-clockwise. 0° = the tip's native orientation.

Smoothing Tab

The Smoothing tab contains options to configure how Harmony should automatically smooth your eraser strokes as you paint.

Tool Name	Description
Centerline Smoothing	Defines the amount of smoothing Harmony should perform on your eraser stroke's direction, curves and corners. A higher setting will prevent your line from being shaky, but is liable to reduce drawing precision and turn sharp angles into curves.
Contour Smoothing	Defines the amount of smoothing Harmony should perform on outer contour of the eraser stroke. A higher setting will round sharp corners and reduce the amount of control points for the resulting vector shape.
