Progressive Display
Updated at:2025-11-03
Overview
BOS allows specifying different image display modes.
When the network environment is poor or the image is large, there are two ways to display the image on a Website:
- Standard display: The image is loaded and displayed row by row from top to bottom.
- Progressive display: The blurry outline of the entire image is shown first, followed by gradual loading until the full image is clear.
Progressive display parameters
Action name: interlace
| Parameters | Value | Description |

Progressive mode is only applicable to JPG and PNG formats. For other formats, the default display mode remains baseline. |
