Feature request: Support EMF image

[erswelljustin]

I am trying to use PhpPresentation to read a sample.pptx file using the simple instructions for readers in the docs and I am getting:

imagecreatefromstring(): Data is not in a recognized format

I have checked that I have PHP7.2-gd installed and all of the other dependencies.

My Code:

require_once 'vendor/autoload.php';

use \PhpOffice\PhpPresentation\PhpPresentation;
use \PhpOffice\PhpPresentation\IOFactory;
use \PhpOffice\PhpPresentation\Style\Color;
use \PhpOffice\PhpPresentation\Style\Alignment;

$oReader = IOFactory::createReader('PowerPoint2007');
$data = $oReader->load(__DIR__ . '/sample.pptx');
var_dump($data);

Can anybody help me understand the issue?

The file with the issue is vendor/phpoffice/phppresentation/src/PhpPresentation/Reader/PowerPoint2007.php

@erswelljustin Which sample.pptx do you use ?

[MrAlexEvers]

I have the exact same issue, with practically the exact same code.

Stackoverflow suggests that the imagecreatefromstring function only handles several image formats.
This is a native PHP function, so I fear a solution might take a while, but I'm looking forward to see if this can/will be solved.

@MrAlexEvers Have you got a sample file ?

[MrAlexEvers]

@Progi1984 The presentations I'm using are from my client, which I fear I am not at liberty to share.
But it contains a .emf file, which cannot be handled by imagecreatefromstring()

Thanks. I will transform in feature request.

Feel free to get inspiration from https://github.com/nikolajlovenhardt/PHPPresentation/releases/tag/0.10.0

I added support for the TIFF format by converting the image using Imagick.

@erswelljustin @MrAlexEvers @nikolajlovenhardt If you have a basic file with EMF/WMF image, I'm interested to add this feature to the reader of the library.

[MrAlexEvers]

@Progi1984 What a blast from the past, this was a request from 5 years ago. I eventually also used an image converter for my EMF issue.

[Progi1984]

@MrAlexEvers Sorry. I'm mainly alone for maintaining this library.

If you have a file, I can continue on it.

[MrAlexEvers]

@Progi1984 I've since given up my developer carreer, I'm afraid.

[Progi1984]

@MrAlexEvers No problem. Thank you for your answer.
