Parameters

Parameter	Input/Output	Description
config	Output	Pointer to the ROI position data. Call the acldvppCreateRoiConfig API to create data of the acldvppRoiConfig type in advance.
left	Input	Left offset. Must be an even number on the Atlas training product. 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 product. 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.
right	Input	Right offset. Must be an odd number on the Atlas training product. Can be an odd or even number on the Atlas inference product. Can be an odd or even number on the Atlas A2 training product/Atlas A2 inference product. Can be an odd or even number on the Atlas A3 training product/Atlas A3 inference product.
top	Input	Top offset. Must be an even number on the Atlas training product. Can be an odd or even number on the Atlas inference product. Can be an odd or even number on the Atlas A2 training product/Atlas A2 inference product. Can be an odd or even number on the Atlas A3 training product/Atlas A3 inference product.
bottom	Input	Bottom offset. Must be an odd number on the Atlas training product. Can be an odd or even number on the Atlas inference product. Can be an odd or even number on the Atlas A2 training product/Atlas A2 inference product. Can be an odd or even number on the Atlas A3 training product/Atlas A3 inference product.
