Premultiplied Alpha - when checked, the calculations for every pixel’s RGB consider the background colour.
If Premultiplied Alpha is not checked, the background colour is not considered.

  • Figure A shows a sprite in Director as it looks on the stage.
  • Figure B shows the exported image with Premultipled Alpha, not checked,
    and with a background colour, which is identical to the background colour in Director.
    The red circle of the exported image looks the same as the sprite on the stage.
  • Figure C shows the exported image with Premultipled Alpha checked and with a background colour,
    which is identical to the background colour in Director. We can see that the red colour of the circle
    of the exported image is affected by the grey colour of the background in Director.

A. A sprite in Director as it looks on the stage. B. premultiplied alpha off.
C. premultiplied alpha on.
