Input parameters

Documentation illustration (illustration unavailable in the archive). Image Src : class, type accepted U8, I16, RGB and HSL.

Documentation illustration (illustration unavailable in the archive). Optional Rectangle : cluster, defines a four-element cluster that contains the left, top, right, and bottom coordinates of the region to process. The VI applies the operation to the entire image if the four-element are equal to 0.

Documentation illustration (illustration unavailable in the archive). Left : integer, left coordinate.
Documentation illustration (illustration unavailable in the archive). Top : integer, top coordinate.
Documentation illustration (illustration unavailable in the archive). Right : integer, right coordinate.
Documentation illustration (illustration unavailable in the archive). Bottom : integer, bottom coordinate.

Documentation illustration (illustration unavailable in the archive). Width (X) : integer, output image width.
Documentation illustration (illustration unavailable in the archive). Height (Y) : integer, output image height.
Documentation illustration (illustration unavailable in the archive). Interpolation : integer, specifies the interpolation method used to resample the image.

- - INTER_NEAREST : nearest neighbor interpolation
  - INTER_LINEAR : bilinear interpolation
  - INTER_CUBIC : bicubic interpolation
  - INTER_AREA : resampling using pixel area relation. It may be a preferred method for image decimation, as it gives moire’-free results. But when the image is zoomed, it is similar to the INTER_NEAREST method
  - INTER_LANCZOS4 : Lanczos interpolation over 8×8 neighborhood
  - INTER_LINEAR_EXACT : bit exact bilinear interpolation
  - INTER_NEAREST_EXACT : bit exact nearest neighbor interpolation
