Overlay Images

../../../../_images/image_overlay.svg

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.

    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

  • 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
