The X11 rastering functions introduced in version 0.3-beta provide a
considerably higher level of abstraction than the standard rastering
functions. To show the effect in xglyph
, a few additional buttons are
provided.

This button allows to switch between transparent and opaque mode in the X11
rastering functions. In transparent mode, only non-background pixels are
drawn and all other pixels are left untouched. In opaque mode the entire
area that the bitmap will require is first filled with the background color
and then the bitmap is placed on this area.

This is a label field with six color fields to the right and one color field
to the left. Clicking on one of the color fields located on the right side
will set the foreground color to the respective value (white, black, gray,
red, green or blue). The color field on the left side always shows the
current color selection.

This also is a label field with six color fields to the right and one color
field to the left. It works in analogy to the above and sets the current
background color. Note that in order make the background color active, the
drawing mode must be set to ``opaque''.
