When feeding a PDF as a byte array into the viewer, the PDF renders fine on screen. However, when printing directly to a printer or to a PDF file using Microsoft Print to PDF, there are somewhat opaque boxes that appear disrupting the smooth gradient. The same issue happens when opening the PDF, saved directly from the byte array to a file, in Chrome Version 62.0.3202.62 (Official Build) (64-bit). The attached WriteAllBytes.pdf looks fine in the viewer but prints bad with Pdfium. WriteAllBytesMicrosoftPrintToPdf.pdf is the result of printing with Microsoft Print to PDF from the Patagames viewer. WriteAllBytesChromeMicrosoftPrintToPdf.pdf is the result of opening WriteAllBytes.pdf in Chrome and printing with Microsoft Print to PDF. All of this works fine in Adobe directly. WriteAllBytesAdobeMicrosoftPrintToPdf.pdf is the result of opening WriteAllBytes.pdf in Adobe and printing with Microsoft Print to PDF.

Thanks,
Josh
