This operator looks up a single sample of RGB or RGBA color from a disk image. If the image does not have an alpha channel associated with it (e.g. a JPEG image) and the operator returns RGBA, the alpha component will be set to 1.
This VOP uses point sampling and does not perform filtering of the texture.
RGB or RGBA values.
Image file used for look-up.
Determines how the image is evaluated when the texture coordinates are outside the range 0 to 1. The options are:
repeat). The image map repeats outside the
range 0 to 1. Basically, the integer component
of the texture coordinate is ignored.
streak). Texture coordinates are clamped to
the 0 to 1 range.
decal). Coordinates outside the range 0 to 1
will evaluate to the border color rather than an image
Border color when Decal wrapping is used.
