static

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

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.

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
