FR: expose 'createImage' so can be used w/ other filesystems

[edalzell]

I'm trying to use this great library in a CMS that uses PHP League's Flysystem, so I need to be able to get the contents of the created image to pass into something like this $filesystem->write($path, file_get_contents($temp_path));

To do this, all that needs to happen is to change createImage from protected or public.

Would it help to add a toString() method instead, which returns the raw file content? See https://github.com/mikehaertl/phpwkhtmltopdf/blob/master/src/Pdf.php#L197.

I'd rather prefer to have the same interface on both classes, Pdf and Image.

It’s not text data though, it’s binary data.

But yes as long as there’s a way to retrieve the raw binary data, that would work. However I don’t need the saveAs method either, I need a way to create the image (into temp I guess) and get the either that temp location or the raw data. That’s why I suggested jut exposing createimage

@edalzell I've just pushed a change to master where toString() is implemented. Does this solve your problem?

You don't have to worry about temporary files. This is handled by our php-tmpfile class which will auto-delete any temporary files - unless there was an error.

So awesome, thanks! I'll update my code when you release so that my customer can get the right code when he installs my addon.

I've released 2.3.0 containing this change. Thanks for the suggestion!
