Module WebThese include, for example, R2_BLACK (the target pixels turn always black), R2_NOTCOPYPEN (the target pixel acquires a color that is the inverse of the drawing tool's color), or R2_XORPEN (the target pixel's color is formed by performing an exclusive OR operation between the target pixel and the pixel in the drawing tool).

Is it possible to create an XOR pen like DrawFocusRect()?

WebR2_XORPEN Pixel is a combination of the colors that are in the pen or in the screen, but not in both (final pixel = pen XOR screen pixel). R2_NOTXORPEN Pixel is the inverse of the R2_XORPEN color (final pixel = NOT(pen XOR screen pixel)). Remarks. Sets the current drawing mode. The drawing mode specifies how the colors of the pen and the ...http://computer-programming-forum.com/81-vc/21ec82517f9fe777.htm going on a zoo hunt
