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
