acl.himpi.vpc_crop_resize

C Prototype	*hi_s32 hi_mpi_vpc_crop_resize(hi_vpc_chn chn, const hi_vpc_pic_info source_pic, hi_vpc_crop_resize_region crop_resize_info[], hi_u32 count, hi_u32 task_id, hi_s32 milli_sec);*
Python Function	task_id, ret = acl.himpi.vpc_crop_resize(chn, source_pic, crop_resize_info, count, milli_sec)
Function Usage	Crops one or more ROIs from an image and resizes them to a specified size. This API is asynchronous. The Atlas 200/300/500 Inference Product does not support this API in the current version. The Atlas Training Series Product does not support this API in the current version.
Input Description	chn: int, image processing channel ID. source_pic: dict, original image information. For details, see hi_vpc_pic_info. For details about related restrictions, see #EN-US_TOPIC_0000002128077052/section1676152117452. crop_resize_info: list, cropped image information list. The length is the same as the value of count. For details, see hi_vpc_crop_resize_region. count: int, number of crop and resize ROIs. Must be in the range of [1, 256]. 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: int, task ID, used to identify a task.
