Overview

This document provides an overview of APIs and SDK code samples related to basic image processing.

Scaling

Feature description

Tencent Cloud’s CI uses the imageMogr2 API to scale images.

Method prototype

go
func (s *CIService) Get(ctx context.Context, key string, operation string, opt *ObjectGetOptions, id ...string) (*Response, error)
func (s *CIService) GetToFile(ctx context.Context, key, localpath, operation string, opt *ObjectGetOptions, id ...string) (*Response, error)

Sample request

go
name := "test.jpg"
// Sample 1. Obtain the object from the response body.
resp, err := c.CI.Get(context.Background(), name, "imageMogr2/thumbnail/!50px", nil)
if err != nil {
//ERROR
}
defer resp.Body.Close()
ioutil.ReadAll(resp.Body)
// Sample 2. Download the object.
filepath := "test.jpg"
_, err = c.CI.GetToFile(context.Background(), name, filepath, "imageMogr2/thumbnail/!50px", nil)

Parameter description

Cropping

Feature description

CI uses the imageMogr2 API to crop images, such as regular cropping, scaling and cropping, inscribed circle cropping, rounded corner cropping, and smart cropping.

Sample request

go
name := "test.jpg"
filepath := "test.jpg"
_, err = c.CI.GetToFile(context.Background(), name, filepath, "imageMogr2/cut/600x600x100x10", nil)

Other Basic Image Processing Operations

Feature description

You can perform other basic processing operations on images by changing the value of the operation parameter. For example, you can rotate the image clockwise by 90 degrees as follows:

go
name := "test.jpg"
filepath := "test.jpg"
_, err = c.CI.GetToFile(context.Background(), name, filepath, "imageMogr2/rotate/90", nil)
