_cmnd is used to query parameter values for the current histogram or for
61
a proxy. The histogram state information may be queried by calling
62
_cmnd(GetHistogramParameter) with a __target of _const(HISTOGRAM) (to
63
obtain information for the current histogram table) or
64
_const(PROXY_HISTOGRAM) (to obtain information from the most recent
65
proxy request) and one of the following values for the __pname argument:
75
_const(HISTOGRAM_WIDTH) Histogram table width
76
_const(HISTOGRAM_FORMAT) Internal format
77
_const(HISTOGRAM_RED_SIZE) Red component counter size, in bits
78
_const(HISTOGRAM_GREEN_SIZE) Green component counter size, in bits
88
_const(HISTOGRAM_BLUE_SIZE) Blue component counter size, in bits
89
_const(HISTOGRAM_ALPHA_SIZE) Alpha component counter size, in bits
90
_const(HISTOGRAM_LUMINANCE_SIZE) Luminance component counter size, in bits
91
_const(HISTOGRAM_SINK) Value of the \f2sink\fP parameter
96
_cmnd is present only if _arbstring(imaging) is returned when _cmnd(GetString)
97
is called with an argument of _const(EXTENSIONS).
99
_const(INVALID_ENUM) is generated if __target is not one of the allowable
102
_const(INVALID_ENUM) is generated if __pname is not one of the allowable
105
_const(INVALID_OPERATION) is generated if _cmnd is executed
106
between the execution of _cmnd(Begin) and the corresponding
107
execution of _cmnd(End).
