A few questions

I've managed to build and run the project, and have a few questions:

  1. How can I turn off the wireframe lines?
  2. When I run this on Windows, what rendering technology is it using, GDI, DirectX, or OpenGL?
  3. I notice that you have your own Html and Css parsers. How do they compare to AngleSharp?

Thanks!

  1. turn on/off wireframe
    see https://github.com/LayoutFarm/HtmlRenderer/wiki/3.-Build-The-Project
  2. On Windows, currently we use GDI/GDI+ (System.Drawing).
    But soon ?,
    we will have a new version that based on Google's Angle Project (OpenGL ES2 Api via DirectX)
    This will make it cross-platform.
  3. My Html and Css parse are designed to work with this project.
    We have another Html parser that works with this project -> HtmlKit(https://github.com/jstedfast/HtmlKit).
    I 've not compare them with AngleShape.

Just FYI - OpenGL ES2 has no API to draw text.

Hi @corliss ,
That is a hard point!

I am developing drawing back-end for it!
(use multi-channels signed distance field (msdf) font,
see prepare/PixelFarm-dev)

@corliss , for text rendering in pure C#
still not complete, on progression.

but now we have OpenType Font Glyph rendering
in pure C#. see more => https://github.com/LayoutFarm/Typography

I hope text rendering may complete soon.
