Painting and Erasing
Tablet Support
Clearing
 Painting
with the Right and Left mouse button lets you work with two different colors
at the same time. The left mouse button uses the primary color, and
the right mouse button uses the secondary color. |
Since the secondary color is generally used for clearing operations, using it with the right mouse button can be considered erasing. Almost all tools in PD obey this convention. For example, you can use it with the painting tools, the filled and unfilled rectangle, ellipse, line and arch tools, and even the bristle brush simulation. Even picking up a custom brush with the right mouse button erases what was underneath. |
| Depending on what drawing mode you are using, you may not get the exact results you want with erasing. In pattern mode for example, you will still get a pattern, instead of your secondary color. If you need to, you can switch modes quickly with the keyboard shortcuts. | |
Picking up a custom brush with the right mouse button erases the original area.

|
| If you have a tablet attached to your computer
and want to take advantage of its features, you can toggle several options
on the brush settings panel.
Pressure opacity lets you alter the opacity of your brush based on pressure. The brush will become more opaque the harder you press. |
The tablets eraser is also supported. It will act exactly like painting with the right mouse button, effectively as an eraser. |
| When you clear a buffer, you set its color to
the secondary color. You can select 'Clear' from the buffer menu to do
so.
You can clear the whole buffer, or you can clear a 'selection' made with the alpha channel tools, and you can clear to the primary color, secondary color, white, or black.

There is also the option to clear all the frames of an animation. They will be cleared to the secondary color. |
You
can also use your brush as an erasing tool by painting with the secondary
color.
Pressure
size lets you alter the size of your brush based on the pressure of your
stylus. This option is not on by default, and in some cases and with
some tools, you may not want it on. It is a global setting. It
is not saved with or altered by any tool.
However,
there are several more options available under the clear button on the tool
panel.
