For most efficient storage and compression of images, the GUI will pack the images into groups of 24-bit
RGB bitmap images. This means if there are 1-bit black and white images, 8-bit gray scale images, or any
other image bit-depth (up to 24-bit images), they will be combined to create a composite image. For
example, a composite image could be composed of 24 1-bit images, 3 8-bit images, or a combination of
images of various bit-depths which add up to a 24-bit composite image.
