    Default Difference between DTMs and BitmapMasks?

    Or rather, the disadvantages and advantages between each. I understand what they each are, i just can't really tell why you'd choose a BitmapMask over a DTM as it doesn't seem like it can do anything that a DTM can't; or maybe i'm just missing something. Could anybody be kind enough to explain the difference to me?

    DTMs are colour based, they look for a certain colour on the screen.
    Bitmapmasks are more like shapefinding, they look for a certain shape.
    I made a new script, check it out!.

    so if u put the tol on a DTM to 255(on the parent point) then they are pretty much the same?cept that DTMs dont use the whole shape..just the points

    Well yeah i kinda knew that, i just don't get why one is more useful than the other, it sounds like they both are used for the same things. I seem to remember seeing them used more than DTMs in more advanced scripts, which made me wonder what the difference was.
