Each element of the colorData array is a byte of memory that can hold a single 8-bit value. The
bitmap that is delivered by the camera uses a format of data called BGR32. This means that each pixel
is described as a 32-bit value in the order blue byte, green byte, and red byte. The final byte (which
makes the pixel 32 bits in size) is the transparency value. This is used in computer displays to allow an
image to show through the image underneath it. For the purposes of this example, you can ignore
the transparency value.
