Azure Function app support

I have confirmed with Microsoft that their Windows sandbox blocks the use of pdf2png and other PDF related libraries. I've tested my app in both v1 and v2 of Azure Functions.
See the references here to the restrictions
https://github.com/projectkudu/kudu/wiki/Azure-Web-App-sandbox#unsupported-frameworks
and some references to PDF things that violate these restrictions.

You say pdf2png was tested in Azure. Can you tell me how you deployed it to Azure? Also, any idea what in pdf2png might be violating? Microsoft didn't tell me exactly what pdf2png violates.

I'd really like to get it working in my Azure Function, without have to move to my own VM that would remove the sandbox restriction.

Any ideas?

Thanks,
Donnie

base64 is not allowed and input big binary buffer is not allowed,too
Hi, I am a chinese boy, and my english is wrong, so, first of all, I want to say sorry.
I am a beginner of nodejs, when I use your module, I found:

1. if I use pdf base64, it is error.
2. if I user a small binary buffer, it is success, but if I use a big binary buffer (amost 6MB), it is error,and the error is "fs: Error: EBUSY: resource busy or locked, unlink".

Space in File Path

Hi,

It's working fine in case of Path : C:\Users\Test\Image\1\sample_image.png
But when I am passing Path: C:\Users\Test\Image\1\sample image.png
it is not working. So when there is space in a folder name or file name it is not working.

Can you please suggest how to resolve this issue.

Got Workaround by copping files.

ghostScript update

First of all great work with this npm, thank you very much @thnew . As me(@matex1024) and my friend(@eduardomourar) use this library from time to time but we don't want to fork this project or create new project based on that one, it's better to maintain this one then create clones.
For the issue reason I just want say there is new version of ghostScript that has few important changes for out project. We tested changes of new ghostScript just please add as contributors.
Thanks and Best Regars

More than one page

Is it possible to convert a multiple page pdf file into pngs? For example a 3 site pdf would create "test(1).png", "test(2).png" and "test(3).png".

So far I was only be able to convert the first page of a pdf file.

Thanks in advance.

Possible to use on heroku?

I got this working on the local machine (windows). I'm having trouble getting it to run by replacing the path when deploying to heroku. Any tips?

multiple pages

Your examples don't show multiple images like the other mp fork does. Will this one work if I use their multiple page example code?

How do you deal with multipage PDFs?

With the sample code, it seems to just convert the 1st page of the PDF to PNG.

Use on linux without special apt installation of ghostscript

Wanted to know if it's possible to use the script without specially doing apt-get on linux instead have the executable in linux format and simply run the process
