Converting a PDF email loses the background and it then takes on the color of whatever application you use to view.

[pbracken]

I'm trying to convert a few emails as pdfs to image files but they appear to lose the background and then the background is taking on background of the view app which in certain cases makes it unreadable. I've tried setting BackgroundColor and FillColor and other colors but nothing makes a difference. I'm sure there is some setting I'm missing so any help would be appreciated. I have attached a sample email PDF and the subsequent image

using ImageMagick;

foreach(var filePath in Directory.EnumerateFiles("C:\\Users\\PatrickBracken\\Downloads\\Proof of Ownership\\Proof of Ownership"))
{
	if (filePath.EndsWith(".pdf"))
	{
		var settings = new MagickReadSettings()
		{
			//Doesn't appear to do anything in this case
			BackgroundColor = MagickColors.White,
			//Doesn't appear to do anything in this case
			FillColor = MagickColors.White,
		};
		var pdfPages = new MagickImageCollection(filePath, settings);
		var horizontal = pdfPages.AppendVertically();
		horizontal.Write(filePath.Replace(".pdf", ".png"));
	}

You can turn the alpha channel off by going through the pdfPages and turning the alpha channel off with pdfPage.HasAlpha = false;.

Ok that does fix that issue, now my test looks good but the other ones have black backgrounds in certain sections. Any ideas for this? I've tried setting different colors to White but that doesn't appear to have any affect. Maybe I am missing one.

Another option would be this:

image.BackgroundColor = MagickColors.White;
image.Alpha(AlphaOption.Remove);

That was it! Thank you so much for the help.
