Overview

This document provides an overview of APIs and SDK code samples for image advanced compression.
API
Description
Allows you to easily convert images into formats that provide a high compression ratio, such as TPG and HEIF. This effectively reduces the transfer time, loading time, and the use of bandwidth and traffic.

Image Advanced Compression

Feature description

CI uses the imageMogr2 API to provide the image advanced compression feature.

Sample code

<?php

require dirname(__FILE__) . '/../vendor/autoload.php';

$secretId = "SECRETID"; // Replace it with your real `secretId`, which can be viewed and managed in the CAM console at https://console.tencentcloud.com/cam/capi
$secretKey = "SECRETKEY"; // Replace it with your real `secretKey`, which can be viewed and managed in the CAM console at https://console.tencentcloud.com/cam/capi
$region = "ap-beijing"; // Replace it with your real region information, which can be viewed in the console at https://console.tencentcloud.com/cos5/bucket
$cosClient = new Qcloud\\Cos\\Client(
    array(
        'region' => $region,
        'schema' => 'https', // Protocol header, which is `http` by default
        'credentials'=> array(
            'secretId'  => $secretId ,
            'secretKey' => $secretKey)));

try {
        $imageMogrTemplate = new Qcloud\\Cos\\ImageParamTemplate\\ImageMogrTemplate();// Create an instance of the basic image processing parameter template
        $imageMogrTemplate->format('tpg');// Convert the input image to TPG format
        $imageMogrTemplate->format('heif');// Convert the input image to HEIF format
        $result = $cosClient->getObject(array(
        'Bucket' => 'examplebucket-1250000000', // Bucket name in the format of `BucketName-Appid`, which can be viewed in the COS console at https://console.tencentcloud.com/cos5/bucket
        'Key' => 'exampleobject',
        'ImageHandleParam' => $imageMogrTemplate->queryString(),// Generate basic image processing parameters
    ));
    // Request succeeded
    print_r($result);
} catch (\\Exception $e) {
    // Request failed
    echo($e);
}
