netCore support

[agnauck]

are there any plans to port this to netCore and also support Linux and MacOS as well?
This would be a great cross plattform library for manipulating and creating PDF documents.

I dont plan to extend this project in the near future. However, contributions in that direction would be welcome.
As the project already targets the .netstandard, this should not be a hard task provided you can compile the native PDFium libs for your target platforms. I suspect the project already works with .netcore on Windows

[agnauck]

agreed, thanks for your reply.

@agnauck I used this in a Windows .NET Core console app w/o issue, so you can probably close this issue.

Hey all, I've been able to successfully run on macOS using .NET Core 2.2.5 and some pre-built libraries I've found here: https://github.com/bblanchon/pdfium-binaries/releases/tag/chromium/3838. I had to renamed it to libpdfium_x64.dylib and libpdfium_x64.so so dlopen() could find 'em.

My main interest is rasterizing into a Bitmap, which I did with:

using (var doc = new PdfDocument(bytes))
{
	var page = doc.Pages[0];
	using (var bitmap = new PDFiumBitmap((int)page.Width, (int)page.Height, true))
	{
		page.Render(bitmap);

		using (var ms = new MemoryStream()) {
			bitmap.Save(ms);
			return ms.ToArray();
		}
	}
}

I'll now deploy it to an (linux) Azure Web App and update here after.

@igor9silva Any updates on this? How did you get it working?

Never actually did the Linux test, but I do expect it to work. It’s still on our roadmap though.

It's working in Linux, I just tested it. I only installed these packages and it worked like a charm:

• PDFiumSharp
• PDFium.Linux.x64
• PDFium.Windows

Download lib from https://github.com/bblanchon/pdfium-binaries/releases/pdfium-linux-x64.tgz
copy libpdfium.so to your project run path
rename libpdfium.so to pdfium.dll

static void Main(string[] args)
{
	using (var doc = new PdfDocument("/home/kane/pdftoimage/TestDoc.pdf", "password"))
	{
		int i = 0;
		foreach (var page in doc.Pages)
		{
			using (var bitmap = new PDFiumBitmap((int)page.Width, (int)page.Height, true))
			using (var stream = new FileStream($"/home/kane/pdftoimage/{i++}.bmp", FileMode.Create))
			{
				page.Render(bitmap);
				bitmap.Save(stream);
			}
		}
	}
	Console.WriteLine("Hello, World!");
	Console.ReadKey();
}
