Following Dierk's suggestion on custom shapes I've added operator overloading to java.awt.Shape and ShapeProviders, thus reducing the amount of code for creating two-shape based area operations and making shapes more expressive at the same time, thanks Dierk!



// works with any shape operation too! //def r1 = rect( x: 10, y: 10, width: 50, height: 50, asShape: true ) def r1 = [10,10,50,50] as Rectangle def r2 = [35,35,50,50] as Rectangle draw( shape: r1 + r2 ){ //add gradientPaint( y2: 50, color2: 'red' ) } draw( shape: r1 ^ r2 ){ // xor gradientPaint( y2: 50, color2: 'blue' ) transformations { translate(x:100) } } draw( shape: r1 - r2 ){ // subtract gradientPaint( y2: 50, color2: 'darkGreen' ) transformations { translate(y:100) } } draw( shape: r1 & r2 ){ // intersect gradientPaint( y2: 50, color2: 'orange' ) transformations { translate(x:100,y:100) } }

Groovy Holidays!
