Вот код:

                        redArray[0] = 0x00000000;
			greenArray[0] = 0x00000000;
			blueArray[0] = 0x00000000;
			redArray2[0] = 0x00000000;
			greenArray2[0] = 0x00000000;
			blueArray2[0] = 0x00000000;
			alphaArray2[0] = 0x00000000;
			
			
			for (i = 1; i <= 255; i++) 
			{
				redArray[i]   = 0x00400000;
				greenArray[i] = 0x00200000;
				blueArray[i]  = 0x00100000;
				redArray2[i]  = 0xFF000000;
				greenArray2[i]  = 0x00000000;
				blueArray2[i]  = 0x00000000;
				alphaArray2[i]  = 0x00000000;
			}
			
			t1 = getTimer();
			h1.copyPixels(Cmp2Map, h1.rect,new Point(0,0));
			h1.draw (Cmp1Map, null, null, "subtract");
			h1.paletteMap(h1, h1.rect, new Point(0, 0), redArray, greenArray, blueArray);
			
			h2.copyPixels(Cmp1Map, h2.rect,new Point(0,0));
			h2.draw (Cmp2Map, null, null, "subtract");
			h2.paletteMap(h2, h2.rect, new Point(0, 0), redArray, greenArray, blueArray);
			
			h1.draw(h2, null, null, "subtract");
			h1.paletteMap(h1, h1.rect, new Point(0, 0), redArray2,greenArray2,blueArray2,alphaArray2);
		
			
			Map1 = Cmp1Map.clone();
			Map1.copyPixels(Cmp2Map, h1.rect, new Point (0, 0), h1, null, true);

Если интересно могу объяснить, что там происходит
