Examples
The Bitmap Drawer component must be linked to the graphical LCD using the gLCD Object property.

The bitmap files used in the example can be found here.
Here is another example which overlays several monochrome images to give the impression of animation. Shows a pair of eyes, which can randomly and momentarily look left, right or blink.
The bitmap files used in the example can be found here.
