WMF

You can load .wmf files.

Backends

You can one of two current backends : gd or imagick. If you don't know which one used, you can use the magic one.

By default, the order of the backends is Imagick, followed by GD. Each backend is tested on different criteria: extension loaded, format support.

<?php

use PhpOffice\WMF\Reader\WMF\GD;
use PhpOffice\WMF\Reader\WMF\Imagick;
use PhpOffice\WMF\Reader\WMF\Magic;

// Choose which backend you want
$reader = new GD();
$reader = new Imagick();
$reader = new Magic();

$reader->load('sample.wmf');

For next samples, I will use the magic one.

getBackends

This specific method for Magic::class returns backends sorted by priority.

<?php

use PhpOffice\WMF\Reader\WMF\Magic;

$reader = new Magic();

var_dump($reader->getBackends());

setBackends

This specific method for Magic::class defines backends sorted by priority.

<?php

use PhpOffice\WMF\Reader\WMF\GD;
use PhpOffice\WMF\Reader\WMF\Imagick;
use PhpOffice\WMF\Reader\WMF\Magic;

$reader = new Magic();
$reader->setBackends([
  GD::class,
  Imagick::class,
]);

var_dump($reader->getBackends());

Methods

getResource

The method returns the resource used in internal by the library.

The GD backend returns a GDImage object or resource, depending the PHP version. The Imagick backend returns a Imagick object.

<?php

use PhpOffice\WMF\Reader\WMF\Magic;

$reader = new Magic();
$reader->load('sample.wmf');

var_dump($reader->getResource());

getMediaType

The method returns the media type for a WMF file.

<?php

use PhpOffice\WMF\Reader\WMF\Magic;

$reader = new Magic();

$mediaType = $reader->getMediaType();

echo 'The media type for a WMF file is ' . $$mediaType;

isWMF

The method returns if the file is supported by the library.

<?php

use PhpOffice\WMF\Reader\WMF\Magic;

$reader = new Magic();
$reader->load('sample.wmf');

$isWMF = $reader->isWMF();

echo 'The file sample.wmf ' . ($isWMF ? 'is a WMF file' : 'is not a WMF file');

load

The method loads a WMF file in the object. The method returns true if the file has been correctly loaded, or false if it has not.

<?php

use PhpOffice\WMF\Reader\WMF\Magic;

$reader = new Magic();
$reader->load('sample.wmf');

loadFromString

The method loads a WMF file in the object from a string. The method returns true if the file has been correctly loaded, or false if it has not.

<?php

use PhpOffice\WMF\Reader\WMF\Magic;

$reader = new Magic();
$reader->loadFromString(file_get_contents('sample.wmf'));

save

The method transforms the loaded WMF file in an another image.

<?php

use PhpOffice\WMF\Reader\WMF\Magic;

$reader = new Magic();
$reader->load('sample.wmf');
$reader->save('sample.png', 'png');
