## Introduction vtkImageProperty -- image display properties vtkImageProperty is an object that allows control of the display of an image slice. ## See Also [vtkImageMapper](./Rendering_Core_ImageMapper.html) [vtkImageProperty](./Rendering_Core_ImageProperty.html) ## Methods ### getInterpolationType ### getInterpolationTypeAsString ### setInterpolationTypeToNearest ### setInterpolationTypeToLinear Set/Get the interpolation type for sampling a volume. The initial value is LINEAR. NEAREST interpolation will snap to the closest voxel, LINEAR will perform bilinear interpolation to compute a scalar value from surrounding voxels. ### colorWindow Controls the window in a window level mapping of the input image. Window level mapping is a technique to map the raw data values of an image into screen intensities in a manner akin to pixelIntensity = (inputValue - level)/window; ### colorLevel Controls the level in a window level mapping of the input image. Window level mapping is a technique to map the raw data values of an image into screen intensities in a manner akin to pixelIntensity = (inputValue - level)/window; ### ambient Control the ambient lighting intensity for this image. ### diffuse Control the diffuse lighting intensity of this image. ### opacity Control the opacity of this image. ### independentComponents Specify whether image components (0 - 3) are treated independently or dependently. If `independentComponents` is `true`, each image component will be treated as an independent "intensity" value and used to look up a color and piecewise function value independently. ### set/get rGBTransferFunction Specify or retrieve, per component, a vtkColorTransferFunction to map scalars to colors. If set, then colorWindow and colorLevel are not used. The set method takes two arguments, a component index and an rgb transfer function, in that order. ### set/get scalarOpacity The `scalarOpacity` property is an alias for `piecewiseFunction`. ### set/get piecewiseFunction Specify or retrieve, per component, a vtkPiecewiseFunction. If `independentComponents` is `true`, the piecewise function is used as a component weighting function, and resulting colors on the screen will be blended using the weights which are normalized per fragment in the fragment shader. If `independentComponents` is `false`, then the piecewise function will be used as a traditional scalar opacity function to map image intensities to opacities. This latter way of using the piecewise function will only work on single-component images. In either case, the overall image opacity can still be affected by the `opacity` property. The set method takes two arguments, a component index and a piecewise function, in that order. ### set/get componentWeight Specify or retrieve, per component, a single scalar weight value to be applied to the entire image for that component. This can be used, for example, to completely disgregard the contribution from a single component. The set method takes two arguments, a component index and an floating point component weight, in that order.
