Set the stroke color for XOR drawing
void PgSetStrokeXORColor( PgColor_t frgd, PgColor_t bkgd ); void PgSetStrokeXORColorCx( PhGC_t *gc, PgColor_t frgd, PgColor_t bkgd );
ph
These functions set the draw color for outlines. When an application XORs this color with the color bkgd, the result is the color frgd.
Since XOR is a reflexive function, frgd and bkgd may be reversed.
PgSetStrokeXORColor() works on the current graphics context, while you can specify the graphics context gc for PgSetStrokeXORColorCx().
