Description

Makes the borders of the input image. This API is asynchronous.

Prototype

hi_s32 hi_mpi_vpc_copy_make_border (hi_vpc_chn chn, const hi_vpc_pic_info *source_pic, hi_vpc_pic_info *dest_pic, hi_vpc_make_border_info make_border_info, hi_u32 *task_id, hi_s32 milli_sec)

Parameters

Parameter	Input/Output	Description
chn	Input	Channel ID for image processing. Atlas A3 training products/Atlas A3 inference products: The value range of this parameter is [0, 256). The maximum number of channels is 256. Atlas A2 training products/Atlas A2 inference products: The value range of this parameter is [0, 256). The maximum number of channels is 256. Atlas 200I/500 A2 inference products: The value range of this parameter is [0, 128). The maximum number of channels is 128. Atlas inference products: The value range of this parameter is [0, 256). The maximum number of channels is 256.
source_pic	Input	Pointer to the source image information.
dest_pic	Input	Pointer to the destination image information.
make_border_info	Input	Information about border making.
task_id	Output	Pointer to the task ID, which is used to identify a task.
milli_sec	Input	Timeout interval (ms): –1: blocking mode 0: non-blocking mode > 0: timeout interval (timeout mode). The timeout interval varies with the operating system. The deviation is generally within a time slice of an operating system. For example, if the time slice of an operating system is 4 ms and the value of milli_sec is set to 1, the actual timeout interval ranges from 1 ms to 5 ms. When the CPU load is high, the timeout interval may fluctuate.

Returns

0: success
Other values: failure. For details, see VPC Return Codes.

Restrictions

Model	Restriction
Atlas inference products	The input and output image resolution must be in the range of [10 × 6, 4096 × 4096]. For details about the input and output image formats, width and height alignment, and buffer size, see Restrictions on Image Formats, Width and Height Alignment, and Buffers. The image width does not need to be a multiple of 16. However, the width stride must be a multiple of 16. Due to restrictions on downsampling of YUV images, note that: For the YUV420SP output format, even numbers are recommended for the border lengths at the top, bottom, left, and right of the image. For the YUV422SP output format, even numbers are recommended for the border lengths at the left and right of the image.
