GLGETPIXELMAP(3G)														 GLGETPIXELMAP(3G)

NAME

       glGetPixelMapfv, glGetPixelMapuiv, glGetPixelMapusv - return the specified pixel map

C SPECIFICATION

       void glGetPixelMapfv( GLenum map,
			     GLfloat *values )
       void glGetPixelMapuiv( GLenum map,
			      GLuint *values )
       void glGetPixelMapusv( GLenum map,
			      GLushort *values )

PARAMETERS

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

       values  Returns the pixel map contents.

DESCRIPTION

       See  the  glPixelMap  reference page for a description of the acceptable values for the map parameter.  glGetPixelMap returns in values the
       contents of the pixel map specified in map.  Pixel maps	are  used  during  the	execution  of  glReadPixels,  glDrawPixels,  glCopyPixels,
       glTexImage1D,   glTexImage2D,   glTexImage3D,   glTexSubImage1D,   glTexSubImage2D,  glTexSubImage3D,  glCopyTexImage1D,  glCopyTexImage2D,
       glCopyTexSubImage1D,  glCopyTexSubImage2D,  glCopyTexSubImage3D,  glColorTable,	glColorSubTable,  glCopyColorTable,   glCopyColorSubTable,
       glConvolutionFilter1D,  glConvolutionFilter2D,  glSeparableFilter2D,  glGetHistogram,  glGetMinmax, and glGetTexImage 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 map, call glGet with the appropriate symbolic constant.

NOTES

       If an error is generated, no change is made to the contents of values.

ERRORS

       GL_INVALID_ENUM is generated if map is not an accepted value.

       GL_INVALID_OPERATION is generated if glGetPixelMap is executed between the execution of glBegin and the corresponding execution of glEnd.
