SUMMARY

A Windows 95 print driver is capable of rendering images into a 4-, 8-, 16-, 24-, or 32-bits-per-pixel Device Independent Bitmap format.

MORE INFORMATION

In order to support rendering of images up to 32-bits-per-pixel, UNIDRV.DLL uses the services provided by the DIBENGINE.DLL shipped with the Microsoft Windows 95, Windows 98, or Windows Millennium Edition (Me) operating systems. This can be specified by specifying the number of planes in the sPlanes box as 1 and sBitPixel as 4, 8, 16, 24, or 32.

However, if you choose to use the planar model sPlanes > 1, UNIDRV.DLL uses the DMCOLOR.DLL shipped with the Windows 95, Windows 98, or Windows Me operating systems. DMCOLOR.DLL supports RGB format and, therefore, the bitmap is 3 planes with 1 bit-per-pixel.
