| <p><a class="el" href="class_sk_pixel_xor_xfermode.html">SkPixelXorXfermode</a> implements a simple pixel xor (op ^ src ^ dst). This transformation does not follow premultiplied conventions, therefore this proc *always* returns an opaque color (alpha == 255). Thus it is not really usefull for operating on blended colors. </p> |
