RescaleImage3d

Generates a three-dimensional image with a new size using a user-defined interpolation mode.

Access to parameter description

Class Syntax

Parameters

Class Name RescaleImage3d

Parameter Name Description Type Supported Values Default Value
input
imageSizeX
The X size of the new image, in pixels. Int32 >=1 1024
input
imageSizeY
The Y size of the new image, in pixels. Int32 >=1 1024
input
imageSizeZ
The Z size of the new image, in pixels. Int32 >=1 256
input
inputImage
The input grayscale image. Image Binary, Label, Grayscale or Multispectral nullptr
input
interpolationType
The interpolation mode. Method used to calculate the intensity of each result pixel
NEAREST_NEIGHBOR Assign the gray level of the nearest pixel.
LINEAR Assign the bilinear interpolation from the four nearest pixels.
SPLINE Assign the cubic interpolation from the nearest pixels.
Enumeration NEAREST_NEIGHBOR
output
outputImage
The output image. Its type is forced to the same value as the input. Its dimensions depend on the image size parameters. Image nullptr
