Samples data from a single image, with provisions for tiling and offsetting the image across uv space.

Parameters

file

The URI of an image file. The filename can include one or more substitutions to change the file name (including frame number) that is accessed, as described in Filename Substitutions in the main Specification document.

default

A default value to use if the file reference can not be resolved (e.g. if a <geomtoken>, /nodes/vop/interfacetoken or {hostattr} is included in the filename but no substitution value or default is defined, or if the resolved file URI cannot be read), or if the specified layer does not exist in the file. The default value must be the same type as the <image> element itself. If default is not defined, the default color value will be 0.0 in all channels.

texcoord

The name of a vector2-type node specifying the 2D texture coordinate at which the image data is read. Default is to use the current u,v coordinate.

uvtiling

The tiling rate for the given image along the U and V axes. Mathematically equivalent to multiplying the incoming texture coordinates by the given vector value. Default value is (1.0, 1.0).

uvoffset

The offset for the given image along the U and V axes. Mathematically equivalent to subtracting the given vector value from the incoming texture coordinates. Default value is (0.0, 0.0).

realworldimagesize

The real-world size represented by the file image, with unittype “distance”. A unit attribute may be provided to indicate the units that realworldimagesize is expressed in.

realworldtilesize

The real-world size of a single square 0-1 UV tile, with unittype “distance”. A unit attribute may be provided to indicate the units that realworldtilesize is expressed in.

filtertype

The type of texture filtering to use; standard values include “closest” (nearest-neighbor single-sample), “linear”, and “cubic”. If not specified, an application may use its own default texture filtering method.
