### Image Data

The image data function is an obscure driver entry point. It takes a single scanline of monochrome data, and expands it to the display using the current color and mix. This is supported by eddb_ImageData, in EDDBIMAG.C, which in turn calls eddh_PMImageData, in EDDHIMAG.ASM. This function takes a supplied monochrome bit map, and blt's a single scanline to the display. This function is rarely used. (The OS/2 Tune Editor makes extensive use of image data.)
