NAME
glCopyColorSubTable - respecify a portion of a color tableC 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 GL_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.
