Overlay Images

Combines two images by layering the first (top port) image on top of the other (bottom port) image , with choice for combining operator. Images must have the same number of channels

Algorithms:

• additive

  Adds the two images together where they overlap.

  use alpha channel:

  Use last channel of source images as alpha channel

  alpha:

  Alpha value used when no alpha channel is given

• divide

  Divides bottom image by all other images, one at a time.

  use alpha channel:

  Use last channel of source images as alpha channel

  alpha:

  Alpha value used when no alpha channel is given

• layer

  Layers on image on top of the other, alpha channel (if any) determines transparency. Otherwise alpha value below

  use alpha channel:

  Use last channel of source images as alpha channel

  alpha:

  Alpha value used when no alpha channel is given

• max

  Takes the maximum value of the images.

  use alpha channel:

  Use last channel of source images as alpha channel

  alpha:

  Alpha value used when no alpha channel is given

• median

  Takes the median value of the images.

  use alpha channel:

  Use last channel of source images as alpha channel

  alpha:

  Alpha value used when no alpha channel is given

• min

  Takes the minimum value of the images.

  use alpha channel:

  Use last channel of source images as alpha channel

  alpha:

  Alpha value used when no alpha channel is given

• multiplicative

  Multiplies images where they overlap.

  use alpha channel:

  Use last channel of source images as alpha channel

  alpha:

  Alpha value used when no alpha channel is given

• subtract

  Subtracts top image from bottom.

  use alpha channel:

  Use last channel of source images as alpha channel

  alpha:

  Alpha value used when no alpha channel is given
