- % 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.
- %
-
- % verify that the DevicePixel color space is supported
