#include <vpi/algo/Rescale.h>

Changes the size and scale of a 2D image.

Parameters
[in]streamThe stream where the operation will be queued in.
[in]backendVPI backend that will execute the algorithm.
[in]inputInput image to be rescaled.
[out]outputOutput image with the desired resulting dimensions.
[in]interpolationTypeInterpolation method to be used.
[in]borderBorder extension to be used when sampling pixels outside the image border.
[in]flagsControl flags.
  • 0: default, negation of all other flags.
  • VPI_PRECISE : precise, but potentially slower implementation.
Returns
an error code on failure else VPI_SUCCESS.
