13. services we provide and look forward to meeting your future experimental needs as your research program evolves MED ASSOCIATES INC GRAPHICS DISPLAY ROUTINES Overview of the Procedures The MED PC Graphics Display Routines program can create up to 32 windows on 32 different monitors The program can only create one graphics window per monitor Each graphics window is capable of showing one bitmap or being flooded with one solid color When a bitmap is displayed it is expanded to fill the entire window so if the picture resolution size shape location is important then the bitmap should be the same dimensions as the monitor Program functions allow the user to control when the graphics window is displayed and what bitmap color is displayed on the graphics window This program is useful in cases where a specific visual stimulus should be displayed on a computer screen The Graphics Display Routines CD contains three sample MED PC programs MEDPC Window mpc MEDPC Window 1 mpc and MEDPC Window 2 mpc These sample programs assume that two monitors are being used MEDPC Window 1 mpc opens a graphics window on the first monitor only MEDPC Window 2 mpc opens a graphics window on the second monitor only and MEDPC Window mpc opens a graphics window on both monitors at the same time The Graphics Display Routines CD also includes MEDPCWin Ist which is a list of files for the Graphics Display and several example bitmap files to display Setting
