Examples of tinypng image compression in Linux

More generally is the picture, the picture compression ratio is bigger, accesses the page speed to be quicker. WordPress under the relevant such as WP smush.it can be used for picture compression, but for compression ratio and fidelity level, as tinypng. WordPress also provides the appropriate plug-ins, but the free version of each mailbox users only provide 500 requests per month compression. This combination of its official API, made a shell version of the gadget, in addition to the previous PHP upload and tinypng PHP API also wrote a web version of the tool.

First, Shell version

When the request API URL is executed directly through the Curl request:

[Root@361way tmp]# curl-i--user api:asidfs1vd1ufx7pipdodfsvoaytaavn--data-binary @delrepo2. png https:// Api.tinypng.com/shrink

Where the location address is the address that the compressed picture is stored on the server after it is executed. Finally, the address can be taken back from the remote by wget or curl.

The following is a shell version written, as follows:

Second, PHP version

You can see the PHP image upload program (full version), here is the PHP with Curl API version, the code is as follows:

<?php
/******************************************************************************
Parameter description:
$max _file_size: Upload file size limit, unit byte
$destination _folder: Upload file path
$watermark: Whether additional watermark (1 for Watermark, other for no watermark);
Instructions for use:
1. Remove the "Extension=php_gd2.dll" line in front of the php.ini file, because we need to use the GD library;
2. Change Extension_dir = to the directory where your Php_gd2.dll is located;

$uptypes =array (
' Image/jpg ',
' Image/jpeg ',

);

$destination _folder= "uploadimg/"; Upload file path
$watermark = 2; Whether to add watermark (1 for Watermark, other for no watermark);

At last:

The official also provided the Java, Ruby, node.js, Python version of the API, originally wanted to use the Python version, but the local use of the Python version is 2.7 version, and the official offer is python3.x version.
