The Pencil tool is used to draw free hand lines with a hard edge. The
pencil and paintbrush are similar tools. The main difference between the
two tools is that although both use the same type of brush, the pencil
tool will not produce fuzzy edges, even with a very fuzzy brush. It does
not even do anti-aliasing.
Why would you want to work with such a crude tool? Perhaps the most
important usage is when working with very small images, such as icons,
where you operate at a high zoom level and need to get every pixel exactly
right. With the pencil tool, you can be confident that every pixel within
the brush outline will be changed in exactly the way you expect.

-
Ctrl
-
This key changes the pencil to a Color Picker.
-
Shift
-
This key places the pencil tool into straight
line mode. Holding Shift while clicking
Button 1 will generate a straight

See the Brush Tools
Overview for a description of tool options that apply to
many or all brush tools.

-
Overview
-
The available tool options can be accessed by double clicking
the Pencil Tool icon.
-
Opacity
-
The Opacity slider sets the transparency level for the paint.
A higher opacity setting results in a more opaque fill and a
lower setting results in a more transparent fill.
-
Mode
-
The Mode dropdown list provides a selection of paint
application modes. A list of these modes can be found in the
Glossary.
-
Brush
-
Indicates the active brush. Clicking on the brush icon
opens the brush selection dialog.
-
Gradient
-
The dropdown list allows to select a gradient that will be
used if the "Use Color from Gradient" option is checked. This
gradient can be reversed by checking the
Reverse option.
-
Incremental
-
The Incremental checkbox activates incremental paint mode for
the tool so that color opacity increases each time the pencil
passes over the same place but cann't exceed the original
color opacity. More information about incremental mode can be
found in the
glossary.
-
Pressure Sensitivity
-
The Pressure Sensitivity section sets the sensitivity levels for
input devices that support this option.
-
Opacity: Drawing opacity increases with
stylus pen pressure.
-
Size: Drawing width increases with stylus
pressure.
-
Color: Gimp uses the active gradient
colors in order as stylus pressure increases.
-
Fade Out
-
This option sets the stroke to fade out after the specified
distance. The stroke will fade to transparency at the completion
of the set distance.
-
Use Color from Gradient
-
Instead of using the Foreground or Background color, the
color is based on the active gradient selection. By checking
Reverse you can reverse the gradient
direction.
The gradient is painted in a forward direction. The entire
color sequence of the gradient will be rendered within the
Length set.
-
Repeat
-
Sawtooth Wave: Renders the gradient
repeatedly. At each expiry of the distance that has been
set, the gradient will begin rerendering from the beginning.
Triangular Wave: Renders the gradient
repeatedly. At each expiry of the distance that has been
set, the gradient will reverse direction and render in that
direction until the expiry of the distance once more. At
this point, it will begin again until the stroke is
complete.
