     <STRONG>NAME</STRONG>
	  <STRONG>glGetPixelMapfv,</STRONG> <STRONG>glGetPixelMapuiv,</STRONG> <STRONG>glGetPixelMapusv</STRONG> -	return
	  the specified	pixel map


     <STRONG>C</STRONG> <STRONG>SPECIFICATION</STRONG>
	  void <STRONG>glGetPixelMapfv</STRONG>(	GLenum <EM>map</EM>,
				GLfloat	*<EM>values</EM>	)
	  void <STRONG>glGetPixelMapuiv</STRONG>( GLenum	<EM>map</EM>,
				 GLuint	*<EM>values</EM>	)
	  void <STRONG>glGetPixelMapusv</STRONG>( GLenum	<EM>map</EM>,
				 GLushort *<EM>values</EM> )


     <STRONG>PARAMETERS</STRONG>
	  <EM>map</EM>	  Specifies the	name of	the pixel map to return.
		  Accepted values are <STRONG>GL_PIXEL_MAP_I_TO_I</STRONG>,
		  <STRONG>GL_PIXEL_MAP_S_TO_S</STRONG>, <STRONG>GL_PIXEL_MAP_I_TO_R</STRONG>,
		  <STRONG>GL_PIXEL_MAP_I_TO_G</STRONG>, <STRONG>GL_PIXEL_MAP_I_TO_B</STRONG>,
		  <STRONG>GL_PIXEL_MAP_I_TO_A</STRONG>, <STRONG>GL_PIXEL_MAP_R_TO_R</STRONG>,
		  <STRONG>GL_PIXEL_MAP_G_TO_G</STRONG>, <STRONG>GL_PIXEL_MAP_B_TO_B</STRONG>, and
		  <STRONG>GL_PIXEL_MAP_A_TO_A</STRONG>.

	  <EM>values</EM>  Returns the pixel map	contents.

     <STRONG>DESCRIPTION</STRONG>
	  See the <STRONG>glPixelMap</STRONG> reference page for	a description of the
	  acceptable values for	the <EM>map</EM>	parameter.  <STRONG>glGetPixelMap</STRONG>
	  returns in <EM>values</EM> the	contents of the	pixel map specified in
	  <EM>map</EM>.	Pixel maps are used during the execution of
	  <STRONG>glReadPixels</STRONG>,	<STRONG>glDrawPixels</STRONG>, <STRONG>glCopyPixels</STRONG>, <STRONG>glTexImage1D</STRONG>, and
	  <STRONG>glTexImage2D</STRONG> to map color indices, stencil indices, color
	  components, and depth	components to other values.

	  Unsigned integer values, if requested, are linearly mapped
	  from the internal fixed or floating-point representation
	  such that 1.0	maps to	the largest representable integer
	  value, and 0.0 maps to 0.  Return unsigned integer values
	  are undefined	if the map value was not in the	range [0,1].

	  To determine the required size of <EM>map</EM>, call <STRONG>glGet</STRONG> with the
	  appropriate symbolic constant.

     <STRONG>NOTES</STRONG>
	  If an	error is generated, no change is made to the contents
	  of <EM>values</EM>.

     <STRONG>ERRORS</STRONG>
	  <STRONG>GL_INVALID_ENUM</STRONG> is generated if <EM>map</EM> is not an	accepted
	  value.

	  <STRONG>GL_INVALID_OPERATION</STRONG> is generated if <STRONG>glGetPixelMap</STRONG> is
	  executed between the execution of <STRONG>glBegin</STRONG> and	the
	  corresponding	execution of <STRONG>glEnd</STRONG>.
