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. For the Atlas training product, the value must be an even number. If used to describe the paste ROI, the left offset must be rounded up to the nearest multiple of 16. For the Atlas inference product, the value does not need to be an even number. If used to describe the paste ROI, the left offset must be rounded up to the nearest multiple of 16. For the Atlas A2 training product/Atlas A2 inference product, the value does not need to be an even number or aligned. For the Atlas A3 training product/Atlas A3 inference product, the value does not need to be an even number or aligned.
