Bitmap File Creation
In addition to fonts, Matrix Orbital graphic displays can also hold a number of customizable bitmaps to
provide further stylistic product integration. Like font files, bitmaps files are most easily uploaded to a
display using MOGD#. However, the critical data component of the bitmap upload command is detailed
below for reference.
The bitmap data block is similar to that of a font. However, as a bitmap is a single glyph, only a simple
two byte header is required. First, one byte representing the bitmap width is sent, then one byte for the
height. Each bitmap is merely encoded in binary fashion using a series of ones and zeroes. Again a grid
can be created using the width and height specified in the upload command, populated in the manner
above, and converted into byte values. A smiley face example is shown below to indicate the ultimate
affect of the Matrix Orbital graphic stylization ability.

Bitmap Masking
Like a regular bitmap, a mask can be loaded to the display and used to create a more polished result
when drawing in populated areas. When defining a mask, all active values will clear any background
information, while any inactive values will leave it untouched. This is best described with an example.
