+% DevicePixel color space method dictionaries.

+%
+% This file implements the DevicePixel color space. See gs_cspace.ps
+% for information.
+%
+% The DevicePixel color space includes a single parameter, the bit
+% depth of the device color representation. Color is expressed as
+% single integers in an opaque, device-specific format.
