acl.himpi.vpc_warp_affine

C Prototype	*hi_s32 hi_mpi_vpc_warp_affine(hi_vpc_chn chn, hi_transform_matrix matrix, hi_warp_transform_param transform_param, hi_u32 task_id, hi_s32 milli_sec)**
Python Function	task_id, ret = acl.himpi.vpc_warp_affine(chn, matrix, transform_param, milli_sec)
Function Usage	Performs affine transformation on the input image. The Atlas 200/300/500 Inference Product does not support this API. The Atlas Training Series Product does not support this API.
Input Description	chn: int, image processing channel ID. matrix: dict, dictionary of the matrix required for affine transformation. For details, see hi_transform_matrix. It can be obtained by calling acl.himpi.vpc_get_affine_transform or acl.himpi.vpc_get_rotation_matrix. transform_param: dict, affine transformation parameters. The input and output image information is configured in the hi_warp_transform_param dictionary.. milli_sec: int, timeout interval (ms). -1: blocking mode. 0: non-blocking mode. > 0: timeout interval (timeout mode). The timeout interval varies with the operating system. The deviation is generally within a time slice of an operating system. For example, if the time slice of an operating system is 4 ms and the value of milli_sec is set to 1, the actual timeout interval ranges from 1 ms to 5 ms. When the CPU load is high, the timeout interval may fluctuate.
Return Value	ret: int, error code. 0 indicates success. Other values: failure. For details, see VPC Return Codes. task_id: task ID, used to identify a task.
