The Atlas Training Series Product does not support this API.

Crops one or more ROIs from an image. This API is asynchronous.

hi_s32 hi_mpi_vpc_crop(hi_vpc_chn chn, const hi_vpc_pic_info *source_pic, hi_vpc_crop_region_info crop_info[], hi_u32 count, hi_u32 *task_id, hi_s32 milli_sec)

Parameter	Input/Output	Description
chn	Input	Channel ID for image processing.
source_pic	Input	Pointer to the source image information.
crop_info	Input	Image cropping information array. The array length is the same as that of the count value.
count	Input	Number of crop ROIs. Must be in the range of [1, 256].
task_id	Output	Pointer to the task ID, used to identify a task.
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.
