Encode

Function Usage

Image encoding API of the ImageProcessor class. The memory allocated by this API does not need to be managed or destroyed by users.

For details, see Image Encoding.

• Maximum resolution of the input image: 8192 x 8192
• Minimum resolution of the input image: 32 x 32
• The actual width and height of the input image must be even numbers. If they are odd numbers, they are automatically rounded up to an even number. The encoded image automatically pads one pixel.
• Input image width: a multiple of 16 for YUV420SP or RGB data
• Input image height: same as the input height or the value rounded up to the nearest multiple of 16 (at least 32)
• Input format.
  • Atlas 200/300/500 inference product: YUV_SP_420 and YVU_SP_420 (nv12 and nv21)
  • Atlas 200I/500 A2 inference product: YUV_SP_420 and YVU_SP_420 (nv12 and nv21)
  • Atlas inference product and Atlas 800I A2 inference product: YUV_SP_420, YVU_SP_420, RGB_888 and BGR_888 (nv12, nv21, rgb, and bgr). The resolution of the RGB (BGR) image format cannot exceed 4096 x 4096.
• Output image format: JPEG, for example, *.jpg
