**Table 1** Image processing functions
Function	Description	Use
Obtaining Image Information	Obtains the basic information of an image, including: format, size, and average color value.	Calling APIs
Brightness	Enhances image effects, including brightness, contrast ratio, sharpness, and blur.	Console GUI Coding Calling APIs
Resizing Images	Resizes images based on specified width and height.	Coding Calling APIs
Public Parameters	Adds watermarks to images at specified positions. Watermarks can be texts, pictures, and their combinations. The color, font, and size of the text on watermarks are adjustable, and you can also resize, rotate, and crop watermarks.	Console GUI Coding Calling APIs
Converting Formats	Converts images to various formats, and supports interlaced rendered images after conversion.	Console GUI Coding Calling APIs
Rotation Settings	Rotates images clockwise, and supports automatic rotation according to the rotation configuration of cameras and mobile phones.	Coding Calling APIs
Common Cropping	Crops images according to the specified width, height, circle radius, index mode, and rounded rectangle.	Coding Calling APIs
Changing Quality	Compresses JPG images based on the relative quality and absolute quality. After compression, the image quality is reduced but occupies less space. In scenarios that do not require high image quality, this function helps you save traffic and have faster image loading.	Coding Calling APIs
Slimming Images	Reduces the image size without compromising its quality. This function helps to slim images while maintaining the original quality, accelerating loading and saving traffic.	Coding Calling APIs
Image Persistency	Persistency indicates that images are asynchronously stored in the specified OBS bucket, so that you can access the processed images directly, improving user experience.	Coding Calling APIs
Command Access Method	Orchestrates multiple process commands in sequence. With this function, you can add multiple process commands to the URL of the image that you want to process, and separate each command using the designated delimiter. Then the commands are executed one by one from left to right.	Coding Calling APIs
Creating Image Styles	Customizes image styles. Each image style specifies a set of process operations. For images require the same process operations, you can create an image style to batch process them.	Console GUI Coding
