Verify.PDFium

Extends Verify to allow verification of PDF documents via PDFium.

Verifying a pdf produces:

• A .verified.txt with the page count, per-page size (in PDF points) and extracted text, and document information dictionary entries (Title, Author, Producer, dates, etc).
• The pdf itself as .verified.pdf.
• A PNG render of every page as #page_0001.verified.png, #page_0002.verified.png, etc.

Rendering is provided by Morph.PDFium, which wraps the prebuilt PDFium binaries from pdfium-binaries (Windows, Linux, and macOS). Rendering is deterministic for a given Morph.PDFium version: the same input produces byte-identical PNGs on every machine and OS, and no image library dependency is added.

See Milestones for release notes.

Usage

Enable Verify.PDFium

[ModuleInitializer]
public static void Initialize() =>
    VerifyPDFium.Initialize();

^{snippet source | anchor}

Initialize optionally takes the render resolution: VerifyPDFium.Initialize(dpi: 150). The default 96 dpi renders an A4 page at 794 x 1123.

Verify a file

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

^{snippet source | anchor}

Verify a Stream

[Test]
public Task VerifyPdfStream()
{
    var stream = new MemoryStream(File.ReadAllBytes("sample.pdf"));
    return Verify(stream, "pdf");
}
