Members

Member	Description
source_pic1	First input image. For details, see hi_vpc_pic_info.
source_pic2	Second input image. For details, see hi_vpc_pic_info.
dest_pic	Output image. For details, see hi_vpc_pic_info. The buffer address of the output image supports the following configurations: If the buffer address of the output image is the same as that of the first input image, the blending result will be pasted back to pic1_region. In this case, the hi_vpc_pic_info structure information of the output image must be the same as that of the first input image. If the buffer address of the output image is the same as that of the second input image, the blending result will overwrite the second image. In this case, the hi_vpc_pic_info structure information of the output image must be the same as that of the second input image. The buffer address of the output image is different from those of the first and second input images.
pic1_region	Information about the region to be blended in the first input image. The width and height of the region must be the same as those of the second input image. For details, see hi_rect_region.
blend_table_len	Buffer size of the blend table, in bytes. The value must be greater than or equal to the width multiplied by the height of the second input image.
blend_table	Blend table address. The API blends the two images into one based on this blend table.
reserved	This is a reserved parameter. The value is fixed at 0.
