Initialize registers the pdf to png converter and all comparers.

To register only the pdf to png converter:

VerifyImageMagick.RegisterPdfToPngConverter();

[Test]
public Task VerifyPdf() =>
    VerifyFile("sample.pdf");

The following will use ImageMagick to compare the images instead of the default binary comparison.

[Test]
public Task CompareImage() =>
    VerifyFile("sample.jpg");

All comparers can be registered:

VerifyImageMagick.RegisterComparers();

For images with a transparent background, that background can be overridden:

[Test]
public Task BackgroundColor() =>
    VerifyFile("transparent.png")
        .ImageMagickBackground(MagickColors.Blue);

For password-protected PDF, the password can be provided to allow verification:

[Test]
public Task PdfPassword() =>
    VerifyFile("password.pdf")
        .ImageMagickPdfPassword("password");
