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

Documentation

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
