Detailed Description

Remaps the input image, effectively warping it using a user-provided mapping.

Function Documentation

Create a payload for Remap algorithm.

This function allocates all resources needed by the Remap algorithm and ties the returned payload to the given stream.

Parameters

[in]	backend	VPI backend that will execute the algorithm.
[in]	warpMap	Mapping of output into input. It must define a grid with the same size as output image.
[out]	payload	Pointer to a payload handle with the create payload.

Returns: VPI_SUCCESS if payload was created successfully, or some other VPIStatus value in case of error.

Submits the Remap operation to the stream associated with the payload.

Parameters

[in]	stream	The stream where the operation will be queued in.
[in]	payload	Payload created by vpiCreateRemap.
[in]	input	Image to be remapped. In a lens distortion correction context, this would correspond to the distorted image. Valid image types: VPI_IMAGE_FORMAT_NV12
[out]	output	Stores the remapped image. In a lens distortion correction context, this would correspond to the corrected (distortion-free) image. Must have the same type as input.
[in]	interp	Interpolation method to be used. Valid values: VPI_INTERP_NEAREST VPI_INTERP_LINEAR VPI_INTERP_CATMULL_ROM
[in]	bcond	What value to pick if remapped coordinated falls outside input image. Valid values: VPI_BOUNDARY_COND_ZERO

Returns: VPI_SUCCESS if algorithm was submitted successfully, or some other VPIStatus value in case of error.
