[flexcoders] psuedo clipping

Tue, 24 Oct 2006 13:06:23 -0700

I have a Tile container.  Each item in the Tile is a Canvas which contains an Image.  The Image can be moved/dragged within it's parent Canvas.  I want to be able to drag the image around it's parent container and if it goes beyond the bounds of the container, I want the area pf the image that is overflowing the Canvas to be grayed out (like setting clipContent to true but instead of cropping, setting the alpha or overlaying it with a semi-transparent layer).  An extra little problem: the Tile is movable too so I can't simply rely on the fact that the items will stay in the same place relative to the Tile container's parent.

I can think of a lot of bad ways to do this.  Can anyone think of a good way?  Maybe some way to use blendMode that I don't understand or adding a child to layer the Tile container without having it show up as a tile item.  I'm fine with doing intricate extension of classes, I just rather wouldn't and I don't want this to get too CPU intensive.

Thanks,

- Dan
