SPRITE LOADARRAY [#]n, w, h, array%()
Creates the sprite n with width w and height h by reading w*h RGB888 values from array%(). The RGB888 values must be stored in order of columns across and then rows down starting at the top left. This allows the programmer to create simple sprites in a program without needing to load them from disk or read them from the display. The firmware will generate an error if array%() is not big enough to hold the number of values required.
