Object Storage Service:Blur

Scenarios

• Privacy protection: Before you publish an image that contains sensitive information, such as license plate numbers and faces, you can blur part of the image.

• Better visual experience for an image composed of multiple layers: Properly blurring the image can smooth the edges between different layers to provide a more comfortable visual experience.

• Better display of a low-resolution image: When the resolution of an image is low and cannot meet the requirements of a high-definition display, you can blur the image.

Methods

You can use object URLs and OSS SDKs or call API operations to configure image processing (IMG) parameters that are used to process images. You can use object URLs to configure IMG parameters only for public-read or public-read-write images. If you want to configure IMG parameters for private images, use OSS SDKs or call API operations. For more information, see IMG implementation modes.

You can add IMG operations directly to the URL of an image and use Cascading Style Sheets (CSS) to modify image styles and optimize the visual display of the processed image. The following sample code provides an example on how to use the IMG feature to blur an image and then use CSS to improve the visual effect of the processed image:
