{{fbdoc item="title" value="XOR"}}----
Parameter to the ##[[KeyPgPutgraphics Put]]## graphics statement which uses a bit-wise ##[[KeyPgOpXor Xor]]## as the blitting method

{{fbdoc item="syntax"}}##
	**Put** [ //target//, ] [ STEP ] ( //x//,//y// ), //source// [ ,( //x1//,//y1// )-( //x2//,//y2// ) ], **Xor**
##
{{fbdoc item="param"}}
	##**Xor**##
		Required.

{{fbdoc item="desc"}}
	The ##**Xor**## method combines each source pixel with the corresponding destination pixel, using the bit-wise ##[[KeyPgOpXor Xor]]## function.  The result of this is output as the destination pixel.
	This method works in all graphics modes.  There is no mask color, although color values of ##0## (##[[KeyPgRgba RGBA]](0, 0, 0, 0)## in full-color modes) will have no effect, because of the behavior of ##[[KeyPgOpXor Xor]]##.

	In full-color modes, each component (red, green, blue and alpha) is kept in a discrete set of bits, so the operation can be made to only affect some of the channels, by making sure the all the values of the other channels are set to ##0##.
