XcmsQueryColors()					     XcmsQueryColors()

Name
  XcmsQueryColors – obtain the color specifications of the specified col‐
  orcells.

Synopsis
  Status XcmsQueryColors(display, colormap, colors_in_out, ncolors,
  result_format)

	unsigned int ncolors;
	XcmsColorFormat result_format;

Arguments
  display   Specifies the connection to the X server.

  colormap  Specifies the colormap.

  colors_in_out
	    Specifies an array of XcmsColor structures, each pixel member
	    indicating the color cell to query.	 The color specifications
	    for the color cells are returned in these structures.

  ncolors   Specifies the number of  XcmsColor	structures  in	the  col‐
	    ors_in_out array.

  result_format
	    Specifies  the  desired  color  format for the returned color
	    specifications.

Returns
  Zero on failure, non-zero on success.

Availability
  Release 5 and later.

Description
  XcmsQueryColors() obtains the RGB values for the colors stored  in  the
  colormap cells specified by the pixel fields of the specified XcmsColor
  structures, and then converts the values to the target format specified
  by  the  result_format  argument.  If a pixel is not a valid index into
  the specified colormap, a BadValue error results.   If  more	than  one
  pixel is in error, the one that gets reported is arbitrary.

Errors
  BadColor  The colormap argument does not name a defined Colormap.

  BadValue  A  specified  pixel	 does not represent a valid color cell in
	    the specified colormap.

Structures
  The XcmsColor structure and XcmsColorFormat type are shown on the Xcms‐
  Color reference page.
