    vector vs. bitmap masks

    mediafred Level 1

      Are there any real reasons to use a bitmap mask for a bitmap image vs. using a vector one?

          You use the content of the mask to achieve an effect on the object being masked. Masks and masked objects can be bitmaps or vectors.


          • Where a mask is white, the masked object will be fully opaque.
          • Where a mask is black or fully transparent, the masked object will be fully transparent.
          • Where a mask has an intermediate value between white and black, or an intermediate transparency level, the masked object will be proportionally semi-transparent.


          Try using an image (preferably one with a full dynamic range from white to black) as a mask on a vector object and on another image and you'll see some of the interesting things you can do.
