-.LP
-The colormap member is the colormap created by the
-.ZN XCreateColormap
-function.
-The red_max, green_max, and blue_max members give the maximum
-red, green, and blue values, respectively.  
-Each color coefficient ranges from zero to its max, inclusive.  
-For example,
-a common colormap allocation is 3/3/2 (3 planes for red, 3
-planes for green, and 2 planes for blue).  
-This colormap would have red_max = 7, green_max = 7, 
-and blue_max = 3.  
-An alternate allocation that uses only 216 colors is red_max = 5, 
-green_max = 5, and blue_max = 5.
-.LP
-The red_mult, green_mult, and blue_mult members give the
-scale factors used to compose a full pixel value. 
-(See the discussion of the base_pixel members for further information.)
-For a 3/3/2 allocation, red_mult might be 32,
-green_mult might be 4, and blue_mult might be 1.  
-For a 6-colors-each allocation, red_mult might be 36, 
-green_mult might be 6, and blue_mult might be 1.
-.LP
-The base_pixel member gives the base pixel value used to
-compose a full pixel value.  
-Usually, the base_pixel is obtained from a call to the 
-.ZN XAllocColorPlanes
-function.  
-Given integer red, green, and blue coefficients in their appropriate 
-ranges, one then can compute a corresponding pixel value by
-using the following expression:
-.LP
-.Ds
-.TA .5i 1.5i
-.ta .5i 1.5i
-(r * red_mult + g * green_mult + b * blue_mult + base_pixel) & 0xFFFFFFFF
-.De
-.LP
-For 
-.ZN GrayScale
-colormaps, 
-only the colormap, red_max, red_mult, 
-and base_pixel members are defined. 
-The other members are ignored.  
-To compute a 
-.ZN GrayScale 
-pixel value, use the following expression:
-.LP
-.Ds
-.TA .5i 1.5i
-.ta .5i 1.5i
-(gray * red_mult + base_pixel) & 0xFFFFFFFF
-.De
-.LP
-Negative multipliers can be represented by converting the 2's
-complement representation of the multiplier into an unsigned long and
-storing the result in the appropriate _mult field.
-The step of masking by 0xFFFFFFFF effectively converts the resulting
-positive multiplier into a negative one.
-The masking step will take place automatically on many machine architectures,
-depending on the size of the integer type used to do the computation,
-.LP
-The visualid member gives the ID number of the visual from which the
-colormap was created.
-The killid member gives a resource ID that indicates whether
-the cells held by this standard colormap are to be released 
-by freeing the colormap ID or by calling the
-.ZN XKillClient
-function on the indicated resource.
-(Note that this method is necessary for allocating out of an existing colormap.)
-.LP
-The properties containing the 
-.ZN XStandardColormap 
-information have 
-the type RGB_COLOR_MAP.

+Negative multipliers can be represented by converting the 2's

+complement representation of the multiplier into an unsigned long and

+storing the result in the appropriate _mult field.

+The step of masking by 0xFFFFFFFF effectively converts the resulting

+positive multiplier into a negative one.

+The masking step will take place automatically on many machine architectures,

+depending on the size of the integer type used to do the computation,

+The visualid member gives the ID number of the visual from which the

+colormap was created.

+The killid member gives a resource ID that indicates whether

+the cells held by this standard colormap are to be released 

+by freeing the colormap ID or by calling the

+.ZN XKillClient

+function on the indicated resource.

+(Note that this method is necessary for allocating out of an existing colormap.)
