Description

Rotates the input image by 90°, 180°, or 270°.

Prototype

hi_s32 hi_mpi_vpc_rotate (hi_vpc_chn chn, const hi_rotate_param* rotate_param, hi_u32* task_id, hi_s32 milli_sec)

Parameters

Parameter	Input/Output	Description
chn	Input	Channel ID for image processing. Atlas A3 training products/Atlas A3 inference products: The value range of this parameter is [0, 256). The maximum number of channels is 256. Atlas A2 training products/Atlas A2 inference products: The value range of this parameter is [0, 256). The maximum number of channels is 256. Atlas 200I/500 A2 inference products: The value range of this parameter is [0, 128). The maximum number of channels is 128.
rotate_param	Input	Rotation information. The input and output image information and rotation parameters are configured in the hi_rotate_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.

Returns

0: success
Other values: failure (VPC Return Codes)
