ImageSampler

Samples image colour at a specified pixel location.

user

Container for user-defined plugs. Nodes should never make their own plugs here, so users are free to do as they wish.

image

The image to be sampled.

view

The view to be sampled.

channels

The names of the four channels to be sampled.

pixel

The coordinates of the pixel to sample. These can have fractional values and bilinear interpolation will be used to interpolate between adjacent pixels.

Note though that the coordinates at pixel centres are not integers. For example, the centre of the bottom left pixel of an image is at 0.5, 0.5.

color

The sampled colour.
