Sponge Brush Tool

Settings

The following settings can be adjusted from the context toolbar:

• Width—the brush (stroke) size in pixels. Type directly in the text box or drag the pop-up slider to set the value.
• Opacity—how see-through the brush is. Type directly in the text box or drag the pop-up slider to set the value.
• Flow—how fast the brush effect is applied (1% is very slow, 100% is immediate). Type directly in the text box or drag the pop-up slider to set the value.
• Hardness—how hard the edges of the brush are. The brush appears softer as the percentage decreases. Type directly in the text box or drag the pop-up slider to set the value.
• More—click to display the Brushes dialog to access advanced brush settings.
• Stabiliser—enables stroke stabilisation using either a Rope stabiliser or Window stabiliser mode; the former drags the stroke end by a 'rope' to smooth the stroke but lets you introduce sharp corners at increasing rope Length (radius) values by redirecting the slackened rope; the latter will smooth the stroke by averaging sampled input positions within a Window whose size is configurable.
• Force pressure to control size—Click to control brush size with pressure if using a pressure-sensitive device. This overrides brush defaults.
• Saturate—when selected, brush strokes increase the saturation of the existing pixels.
• Desaturate—when selected, brush strokes decrease the saturation of the existing pixels.
• Vibrance—when selected, brush strokes adjust the intensity of subtle coloured pixels, while minimizing clipping of highly saturated coloured pixels.
• Saturation—when selected, adjusts the colour intensity of all pixels.
• Wet Edges—builds paint up along the edges of your pixel brush stroke, producing a watercolour effect. Check Custom and either apply a preset Standard profile or draw a custom profile using the chart; both subtly changes how watery the stroke appears.
