Modify an existing pdf document by adding an image overlay

[raedle]

Hi, great work!

I am trying to add a custom generated QR code (image) to the first page of an existing pdf document. It only works with shapes but as soon as I switch to an image it won't display the image.

Do you have any suggestions?

Example:

{
    "source":{
        "external":"pdfFile"
    },
    "externals": {
        "anshika":"https://raw.githubusercontent.com/galkahana/hummusrenderrer/master/samples/img1.jpg",
        "pdfFile": "http://www.ca7.uscourts.gov/rules/type.pdf"
    },
    "pages": [
        {
            "modifiedFrom": 0,
            "width": 595,
            "height": 842,
            "boxes": [
                {
                    "bottom": 300,
                    "left": 100,
                    "image": {
                        "external":"anshika",
                        "transformation": [0.1, 0, 0, 0.1, 0, 0]
                    }
                }
            ]
        }
    ]
}

Just to verify that i'm getting the same result - running this document description crashes/no return. it's not that you see the PDF without the image or something.

In that case, my suggestion that i find & fix the bug :). will look into it soon.

The document description does not crash. It shows the pdf but without the image.

right. got that one.

found an issue with one of the dependent-on modules (hummus). corrected, updated. should be fine now.
