Drawing Bitmap Objects
You can draw in bitmap objects and use all the different drawing
tools with various fill and strokes settings. The most important
thing to remember is, that the drawing on the bitmap will change
the underlying pixels permanently.
Drawing in selected areas
Remember that when a marquee is visible and pixels are selected
only the selected area will be changed by the drawing tools.
Drawing tools
The
pencil tool will always draw a 1-pixel hard line. No matter what
you enter in the stroke panel, the settings will revert. There are
three options that are displayed in the tool options panel.

Although the line is hard pixels, you can select to draw anti-aliased
and blend it into the image. Auto erase draws the fill color over
the stroke. Preserve transparency means that transparent areas of
the bitmap will not show the drawn stroke.
 The
brush tool offers many different settings through the stroke panel
options in the properties inspector. In combination with a pressure
sensitive tablet and a stylus you can create great digital renditions
of strokes such as calligraphic writing instruments produce.
You can use all contraining key combinations to create straight
lines or lines at predefined angles.
