The amount of scattering depends on the setting of the jitter slider in the Tool Options dialog window. Pressure : At low pressure the brush prints are spread according to the value set in the jitter amount slider.
As the pressure increases the scattering amount decreases. Velocity : mouse At slow speed the brush prints are spread according to the value set in the jitter amount slider. As the speed increase the scattering amount decrease. Direction : mouse The jitter effect depends on the direction of the brush. Fade : mouse Starting with no jitter and ending with the amount of jitter set in the jitter amount slider. The behavior of the fading is set in the fade options in the Tool Options dialog.
If the current options do not suits you, you may fine-tune the settings from the Paint Dynamics Editor. Click on the down arrow to open the drop down menu and then select what option to change. Click on one of the options to open the customizing dialog. The upper part of the dialog contains a curve where you can adjust the behaviour of the chosen parameters selected in the lower part of the dialog. You can drag the curve by pointing on it with the mouse pointer, holding down the left mouse button and the move the curve wherever you want inside the diagram.
The examples shown are very brief, but will perhaps give you an idea of how to use this functions. Feel free to try other combinations. In these examples the foreground color is set to blue ff and the background color to yellow ffff Fading: pixels. Paintbrush size: All other settings are the default values except for those values changed. Example 1 shows the result when the brush size is connected to the fading.
Default options. The brush size starts as zero and increase to the size set in the brush size slider in the Tools Options Dialog. In example 2 the brush size is still connected to the fade tool, but the fade curve is set as in image 5. The brush size starts at zero, fades up to full size and then fades down to zero again.
The full fade length is set along the x-axis from left to right. The y-axis determines the size of the brush. At the bottom the brush size is zero, and at the top of the diagram the brush is set to the full size according to the size set in the slider in the Brush Options Dialog.
Study the example and the curve to see the relationship. In example 3 the brush size is disconnected from the fade tool. The color is connected with the fade option with the curve set as in image 6. At the start of the drawing the color is picked from the left side of the gradient, then gradually more from the right side of the gradient and then finally fading back to the left side again.
As usual the x-axis is the total fade length. When the curve is near the bottom of the diagram the color is picked from the left side of the gradient. With the curve at the top of the diagram the color is picked from the right side of the gradient.
The last example shows a combination of these two settings. Both the size of the brush and the color are connected to the fading function with the curves set as in image 5 and 6. Many of the dynamics behaviors also depends on the settings of the Dynamics Options in the Tool Options dialog and vice versa. For example the fading will not work if it is not applied in the Dynamics section.
This slider determines the length of the fading. What will actually happen depends on the setting of the Dynamic. If set to act on the color for example, the color will be taken from the current gradient starting from the left side of the gradient and moving toward the right side of the gradient.
The Fade Options has a drop down list determining how the fading is repeated. Figure Illustration of the effects of the three gradient-repeat options, for the Abstract 2 gradient.
This option determines what happens if a brush stroke extends farther than the Length specified by the slider. There are three possibilities:. None means that the color from the end of the gradient will be used throughout the remainder of the stroke;. Sawtooth wave means that the gradient will be restarted from the beginning, which will often produce a color discontinuity;.
Triangular wave means that the gradient will be traversed in reverse, afterwards bouncing back and forth until the end of the brush stroke. Here you can choose the gradient to use as color source when using the brush with the color option set.
Click on the box showing the gradient to change to another one from the gradient list. If no color option is selected in the currently used dynamics, the brush will use the foreground color set in the toolbox. Do not forget to tell us the license you chose from the list given above.

Normally, tool options are displayed in a window attached under the Toolbox as soon as you activate a tool. See the Common Paint Tool Options for a description of tool options that apply to many or all paint tools. Motion only : if this option is checked, the airbrush paints only when it moves. The Rate slider adjusts the speed of color application that the airbrush paints. A higher setting will produce darker brush strokes in a shorter amount of time. This slider controls the amount of color that the airbrush paints.
A higher setting here will result in darker strokes. Airbrush 3.
