	)

static

Combines the inputImage and imageToAppend into a new image by max/min operation. The extent will be the union of the two images.

Extent can be specified to restrict modifierImage's extent to a smaller region. inputImage and modifierImage must have the same geometry (origin, spacing, directions) and scalar type, but they may have different extents.

static

Resample an oriented image data to match the geometry of a reference oriented image data

referenceImage	Oriented image containing the desired geometry
outputImage	Output image
linearInterpolation	True if linear interpolation is requested (fractional labelmap), or false for nearest neighbor (binary labelmap). Default is false.
padImage	If enabled then it is made sure that the input image's extent fits into the resampled reference image, so if part of the extent is transformed to be outside the reference extent, then it is padded. Disabled by default.

		double	backgroundColor[4] = `NULL`

static

Transform an oriented image data using a transform that can be linear or non-linear. Linear: simply multiply the geometry matrix with the applied matrix, extent stays the same Non-linear: calculate new extents and change only the extents when applying deformable transform

Parameters

image	Oriented image to transform
transform	Input transform
geometryOnly	Only the geometry of the image is changed according to the transform if this flag is turned on. This flag only has an effect if the transform is non-linear, in which case only the extent is changed. Off by default
alwaysResample	If on, then image data will be resampled even if the applied transform is linear

◆ TransformOrientedImageDataBounds()

		vtkAbstractTransform *	transform,
		double	transformedBounds[6]
