GLCOPYCOLORSUBTABLE(3G) 			    OpenGL Manual			      GLCOPYCOLORSUBTABLE(3G)

NAME
glCopyColorSubTable - respecify a portion of a color table
C SPECIFICATION
void glCopyColorSubTable(GLenum target, GLsizei start, GLint x, GLint y, GLsizei width);
PARAMETERS
target Must be one of GL_COLOR_TABLE, GL_POST_CONVOLUTION_COLOR_TABLE, or GL_POST_COLOR_MATRIX_COLOR_TABLE. start The starting index of the portion of the color table to be replaced. x, y The window coordinates of the left corner of the row of pixels to be copied. width The number of table entries to replace.
DESCRIPTION
glCopyColorSubTable is used to respecify a contiguous portion of a color table previously defined using glColorTable(). The pixels copied from the framebuffer replace the portion of the existing table from indices start to start + x - 1, inclusive. This region may not include any entries outside the range of the color table, as was originally specified. It is not an error to specify a subtexture with width of 0, but such a specification has no effect.
NOTES
glCopyColorSubTable is present only if ARB_imaging is returned when glGetString() is called with an argument of GL_EXTENSIONS.
ERRORS
GL_INVALID_VALUE is generated if target is not a previously defined color table. GL_INVALID_VALUE is generated if target is not one of the allowable values. GL_INVALID_VALUE is generated if start + x > width. GL_INVALID_OPERATION is generated if glCopyColorSubTable is executed between the execution of glBegin() and the corresponding execution of glEnd().
