Performs affine transformation on the input image.

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)

Parameter	Input/Output	Description
chn	Input	Channel ID for image processing.
matrix	Input	Affine transformation matrix obtained by calling hi_mpi_vpc_get_affine_transform or hi_mpi_vpc_get_rotation_matrix.
transform_param	Input	Affine transformation parameter. The input and output image information is configured in the hi_warp_transform_param structure.
milli_sec	Input	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.
task_id	Output	Pointer to the task ID, which is used to identify a task.
