Function Usage

Sets cropping parameters in the dynamic AIPP scenario.

Prototype

aclError aclmdlSetAIPPCropParams(aclmdlAIPP *aippParmsSet, int8_t cropSwitch,
int32_t cropStartPosW, int32_t cropStartPosH,
int32_t cropSizeW, int32_t cropSizeH,
uint64_t batchIndex)

Parameters

Parameter	Input/Output	Description
aippParmsSet	Output	Pointer to the dynamic AIPP parameter object Call aclmdlCreateAIPP in advance to create data of the aclmdlAIPP type.
cropSwitch	Input	Cropping switch 0: disabled. When set to 0, cropStartPosW, cropStartPosH, cropSizeW, and cropSizeH are invalid. 1: enabled
cropStartPosW	Input	Horizontal coordinate of the crop start For YUV420SP_U8, the value must be an even number. Value range: [0, 4095]
cropStartPosH	Input	Vertical coordinate of the crop start For YUV420SP_U8, the value must be an even number. Value range: [0, 4095]
cropSizeW	Input	Width of the crop ROI Value range: [1, 4096]
cropSizeH	Input	Height of the crop ROI Value range: [1, 4096]
batchIndex	Input	Index of batch for image cropping Value range: [0, batchSize) batchSize is set when data of the aclmdlAIPP type is created by the aclmdlCreateAIPP call.

Returns

0 on success; else, failure. For details, see aclError.

Restrictions

If the cropping function is enabled, the following conditions must be met for the arguments passed to the aclmdlSetAIPPSrcImageSize call and aclmdlSetAIPPCropParams call:

cropSizeW+cropStartPosW ≤ srcImageSizeW
cropSizeH+cropStartPosH ≤ srcImageSizeH
