Function

Crops one or more ROIs from one or more input images, resizes each cropped image, pads each resized image, and loads each padded image to the output buffer. This API is asynchronous.

Parameters

Parameter	Input/Output	Description
channelDesc	Input	Pointer to the channel description. Must be the same as the channelDesc argument passed to the acldvppCreateChannel call.
srcBatchPicDescs	Input	Pointer to the description of batch input images. Call acldvppCreateBatchPicDesc to create a description of a group of images. Call acldvppGetPicDesc to obtain the description of a specified image. Call acldvppSetPicDesc series to set the image description (including the buffer address, buffer size, image format, and image resolution).
roiNums	Input	Pointer to the number of crop ROIs of each input image. The maximum number of crop ROIs is 256. roiNums is an array. The sum of the elements is up to 256, which must be consistent with batchSize in the dstBatchPicDescs structure. roiNums[0]+...+roiNums[size-1] <= 256
size	Input	Length of the roiNums array, up to 256.
dstBatchPicDescs	Input/Output	Pointer to the description of batch output images. When dstBatchPicDescs is used as an input, the user needs to: Call acldvppCreateBatchPicDesc to create a description of a group of images. Call acldvppGetPicDesc to obtain the description of a specified image. Call acldvppSetPicDesc series to set the image description (including the buffer address, buffer size, image format, and image resolution).
cropAreas	Input	Pointer array for the crop ROIs. Call acldvppCreateRoiConfig to create an ROI configuration in advance. The cropAreas or borderCfgs array length is the same as the value of batchSize in the dstBatchPicDescs structure.
borderCfgs	Input	Pointer array for the border configurations. The elements in the borderCfgs array match those in cropAreas with ordering preserved. The borderType member can only be set to BORDER_CONSTANT or BORDER_REPLICATE.
resizeConfig	Input	Pointer to the image resizing configuration. Call acldvppCreateResizeConfig to create an image resizing configuration in advance. The width or height of the resized image output by VPC is that of the output image minus the padding length.
stream	Input	Stream. For details, see aclrtStream.

Returns

0 on successful task delivery; else, failure. For details, see aclError.
