aclError acldvppSetRoiConfigLeft(acldvppRoiConfig *config, uint32_t left)

Python Function

ret = acl.media.dvpp_set_roi_config_left(roi_config, left)

Parameter	Description
roi_config	Int, pointer address of the location data of a specified ROI. Call acl.media.dvpp_create_roi_config in advance to create data.
left	Int, left offset. Must be an even number on the Atlas training products. If used to describe the paste ROI, the left offset must be rounded up to the nearest multiple of 16. Can be an odd or even number on the Atlas inference products. If used to describe the paste ROI, the left offset must be rounded up to the nearest multiple of 16. Can be an odd or even number on the Atlas A2 training products/Atlas A2 inference products (no alignment requirement). Can be an odd or even number on the Atlas A3 training products/Atlas A3 inference products (no alignment requirement).
