The initial value is _const(COPY). -.SH DESCRIPTION -_cmnd specifies a logical operation that, -when enabled, -is applied between the incoming color index or RGBA color -and the color index or RGBA color at the corresponding location in the -frame buffer. -To enable or disable the logical operation, call -_cmnd(Enable) and _cmnd(Disable) -using the symbolic constant _const(COLOR_LOGIC_OP) for RGBA mode or -_const(INDEX_LOGIC_OP) for color index mode. The initial value is -disabled for both operations. -.P -.ne -.TS -center; -lb lb -l c. -_ -Opcode Resulting Operation -_ -_const(CLEAR) 0 -_const(SET) 1 -_const(COPY) s -_const(COPY_INVERTED) ~s -_const(NOOP) d -_const(INVERT) ~d -_const(AND) s & d -_const(NAND) ~(s & d) -_const(OR) s | d -_const(NOR) ~(s | d) -_const(XOR) s ^ d -_const(EQUIV) ~(s ^ d) -_const(AND_REVERSE) s & ~d -_const(AND_INVERTED) ~s & d -_const(OR_REVERSE) s | ~d -_const(OR_INVERTED) ~s | d -_ -.TE - -_param1 is a symbolic constant chosen from the list above. -In the explanation of the logical operations, -\f2s\fP represents the incoming color index and -\f2d\fP represents the index in the frame buffer. -Standard C-language operators are used. -As these bitwise operators suggest, -the logical operation is applied independently to each bit pair of the -source and destination indices or colors. -.SH NOTES -Color index logical operations are always supported. RGBA logical -operations are supported only if the GL version is 1.1 or greater. -.P -When more than one RGBA color or index buffer is enabled for drawing, -logical operations are performed separately for each enabled buffer, -using for the destination value the contents of that buffer -(see _cmnd(DrawBuffer)). -.SH ERRORS -_const(INVALID_ENUM) is generated if _param1 is not an accepted value. -.P -_const(INVALID_OPERATION) is generated if _cmnd -is executed between the execution of _cmnd(Begin) -and the corresponding execution of _cmnd(End). -.SH ASSOCIATED GETS -_cmnd(Get) with argument _const(LOGIC_OP_MODE). -.br -_cmnd(IsEnabled) with argument _const(COLOR_LOGIC_OP) or _const(INDEX_LOGIC_OP). -.SH SEE ALSO -_cmnd(AlphaFunc), -_cmnd(BlendFunc), -_cmnd(DrawBuffer), -_cmnd(Enable), -_cmnd(StencilOp) |
