WriteHTML to PDF file has quality loss on images

[DaanDeSmedt]

When writing HTML to a PDF file using the h2p class I notice there is quality loss on the images.
Any tips?

I've added the quality parameter to the render function inside the converter.js file, but that does not show any difference.

page.render(options.destination, { format: 'pdf', quality: '100' });

I've also set the page DPI to 72 and higher... no difference.
