Prototype

C 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)

Python Function

task_id, ret = acl.himpi.vpc_copy_make_border(chn, source_pic, dest_pic, make_border_info, milli_sec)

Parameters

Parameter	Description
chn	Int, channel ID for image processing.
source_pic	Dict, source image information. For details, see hi_vpc_pic_info. For details about related restrictions, see Restrictions.
dest_pic	Dict, destination image information. For details, see hi_vpc_pic_info.
make_border_info	Dict, border making information. For details, see hi_vpc_make_border_info.
milli_sec	Int, timeout interval, in milliseconds.

Return Value

Return Value	Description
task_id	Int, task ID, used to identify a task.
ret	Int, error code. 0 indicates success. Other values indicate failure. For details, see VPC Return Codes.

Restrictions

Version	Restrictions
Atlas inference product	The input and output image resolutions must be in the range of (10 x 6, 4096 x 4096). For details about the input and output image formats, width and height alignment of each image format, and buffer size restrictions, 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, pay attention to the following when the output image format is YUV420SP or YUV422SP: For the YUV420SP output format, it is recommended that the border lengths at the top, bottom, left, and right of the image be even numbers. For the output YUV422SP format, it is recommended that the border lengths at the left and right of the image be even numbers.
