The
Premultiply tool lets you take an input image and create an image
where each pixel color's 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.
NoteWhen 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.
