Algorithms: additive
Adds the two images together where they overlap.
- use alpha:
Use last channel of source images alpha channel
divide
Divides bottom image by all other images.
- use alpha:
Use last channel of source images alpha channel
layer
Layers on image on top of the other, alpha channel (if any)determines transparency.
- use alpha:
Use last channel of source images alpha channel
max
Takes the maximum value of the images.
- use alpha:
Use last channel of source images alpha channel
min
Takes the minimum value of the images.
- use alpha:
Use last channel of source images alpha channel
multiplicative
Multiplies images where they overlap.
- use alpha:
Use last channel of source images alpha channel
subtract
