There are currently two background images available: * a 4-bit/16-color image in backimg.c.16 * an 8-bit/240-color image in backimg.c.256 The appropriate file should be copied to "backimg.c", depending on whether the 4-bit or 8-bit MetaWindows library is in use. The medawindow library needs to be adjusted depending whether 4-bit or 8-bit color is used. The appropriate file should be copied to "Metawndo/LIB/metawndo.o the two files are: * 4-bit/16-color: Metawndo/LIB/Metawndo.640x480x16.o * 8-bit/256-color: Metawndo/LIB/metawndo.640x480x256.o In addition, if the 4-bit library and image are being used, the environment variable "VCOPTS" should include the string "-DNCLR16". "set VCOPTS=-DNCLR16"
