REST7 API

Collection of free web services. No registration required. Wizards available at:

• http://rest7.com/

How to use the webservices?

There's two possibilities:

• check the wizards at rest7.com and generate simple code pieces you need
• download the library from this repository

Using a webservice

You can use a webservice from PHP just like that:

//lets convert image from JPEG to PNG using "image_convert"
$url = 'http://api.rest7.com/v1/image_convert.php?url=http://server.com/image.jpg';

//call API method
$data = json_decode(file_get_contents($url));

//fetch converted image
$image = file_get_contents($data->image);

//save fetched image to disk
file_put_contents('output.png', $image); 

Or you can use a very simple PHP library rest7.php

Example 1: converting image from PNG to DDS

include 'rest7.php';

//load an image from file:
$im = imagecreatefrompng('test.png'); //using a resource, or:
$im = 'http://server.com/dir/test.png'; //using an URL or:
$im = 'dir/test.png'; //using a local file

//convert to DDS
$dds = convertImage7($im, 'dds');

if (!$dds)
{
	echo 'Conversion failed';
}
else
{
	//save to file
	file_put_contents('output.dds', $dds);
}

Example 2: checking if image was upscaled

include 'rest7.php';

//load an image from file:
$im = imagecreatefrompng('test.png'); //using a resource, or:
$im = 'http://server.com/dir/test.png'; //using an URL or:
$im = 'dir/test.png'; //using a local file

$res = imageUpscaled7($im);
if ($res === false)
{
	echo 'Function failed';
}
else if ($res)
{
	echo 'Image was upscaled';
}
else
{
	echo 'Image was not upscaled';
}

And if you just want to load images in different format you can use imagecreatefromfile7.php

Example 1: converting image from PNG to DDS

include 'imagecreatefromfile7.php';

$im = imagecreatefrompsd('image.psd');
imagepng($im, 'output.png');
