Transformation offset factor -

I'm trying to get my head around working with the Matrix class. I'm doing something manually that I'd prefer to do with a transformation. Basically I have shape objects that are responsible for drawing themselves on a surface. The shapes all store their Positions. I calculate an offset factor and all shapes should take their x coordinates and multiply by the offset factor for their new position. So if a shape's position is (100,50) and my offset factor is 0.5, the new position should be (50,50). What I do now is have each shape do this multiplication individually. I'd rather use a transformation. How can I apply this offset using some sort of transformation? Many thanks |

Hi Bob, Thanks. I had already downloaded that example and used it to help come up with the design of my shape objects. So each of your shapes handles it's own transformations, that will work great with what I'm doing.
