Screensaver allows the use of external characters, unlike the Editor
which only has three internal characters.
external characters are simply .bmp (Windows Bitmap) files. These
files can be created using your favorite graphics editor that supports
windows bitmap (.bmp) files.
There are three important things to remember.
The color at the upper left hand corner is used as the transparency
color. Some colors don’t work. For best results use pure white
(RGB 255,255,255) or pure black (RGB 0,0,0). You may open one of
the included .bmp (character) files in your favorite image editor
to examine it.
The HotSpot is located at (2,65). The hotspot is the location in
the bitmap where the drawing takes place. It is the location where
the tip of characters PaintBrush or Pen should be located in the
.bmp file. For example the tip of a characters crayon should be
located 2 pixels from the left, and 65 pixels from the top of the
Although there is no size limit to the bitmaps, the larger the bitmap,
the more work it is for your computer to move it. With that said,
try to keep the size reasonable.
