When we put input checkboxes into our HTML and use HTML to PDF we end up with gradient checkbox controls that are awful on output. Attempts to CSS stlye the checkboxes to simple squares with black borders and a checkmark when selected have not worked.

Any ideas how to correctly do this without introducing images or custom fonts?

Here's the PDF output:

It was created using input checkbox selected tags.

Hi,

Internally EO.Pdf uses a built-in Chromium based browser engine to render the HTML. The current version of EO.Pdf is based on Chromium V81 and this is how Chromium V81 render a checkbox. We are working on a new version that will be based on Chromium V86. Chromium V86 will render checkbox like the current Chrome does.

However you should be able to use CSS to customize checkbox though. As a test, you can use our EOPdfDemo sample application to conver the following Url:

You should see checkbox being customized properly in the result PDF file.

Thanks!
