The Premultiply tool allows you to take an input image and create an image where each pixel’s color component is multiplied
by the pixel's alpha component. The multiplication result is clamped to the color range of the output image.
To premultiply an image using the Premultiply tool:
- Drag the Premultiply tool from the Formatting folder into the dependency graph in the Schematic view.
The image is premultiplied.
Note
When using the Premultiply tool, make sure the output image is never processed by a tool that produces incorrect results while
operating on an image with premultiplied data. Tracking of whether images are stored in premultiplied format or not, does
not occur.
