ReplaceImageChannels
Mix image’s channels of one or two images.
Inputs
Image AFirst image
Image BSecond image
Output
ImageResult image
Parameters
- Red:
source of Red channel
- Green:
source of Green channel
- Blue:
source of Blue channel
- Alpha:
source of Alpha channel
- Color:
contains values for Set to color source option
- If Different Pixel Types:
- Use Highest
use pixel type with bigger depth. Check how pixel types are compared in Pixel Types Comparison
- Use Lowest
use pixel type with lower depth
- Use A’s
use pixel type of Image A’s input
- Use B’s
use pixel type of Image B’s input
- Error
ReplaceImageChannels won’t compute if input images have different pixel types
- Predivide/Postmultiply:
if set, divides images by their alpha on input and multiplies result image by its alpha on output. If alpha value is zero, pixel color is preserved on division.
- Method:
- OpenGL
render via OpenGL. Requires OpenGL 2.1 context
- CPU
slower computing on CPU
Note
If you compute a project using WrapCmd command line interface or Node on a machine where OpenGL 2.1 is not available, the node will return an error, if OpenGL method is selected.
