A lot of things has changed in the past year and it seems more is going to change in the next, unfortunately those changes are not aligned with the work required for HTML Renderer. That's why it took so long for v1.5 release to finally be ready and the reason not all features I originally planned made it.
With a heavy heart I'm going to hold all significant work on HTML Renderer until either my career path brings me back to .NET, I have more free time to work on it or the project will get more attentions. In the meanwhile I will continue to support the library with small fixes and answering question on the discussions/issues pages. Continue reading →
After getting feedback that my original clipboard code doesn't handle all scenarios, especially with Chrome, I went back to the code to get a better understand of what's going on and find the correct way to set plain text and HTML snippet to clipboard.
In case you want to display HTML with highlighted/colored syntax the simplest way to go is use WinForms RichTextBox, all is needed is to add RTF color tags surrounding HTML elements.
This helper class goal is exactly that, given a string containing HTML code it will return an RTF formatted string with the HTML elements colored.
I have used Alun Evans code as base, improving its coloring support and performance.
See it's usage in HtmlRenderer project.
The requirement to generate image from HTML snippet appears to be quite popular, as seen in a few StackOverflow questions1, so I have decided to properly support it in HTML Renderer to simplify the process and improve the results.
The support for image generation in HTML Renderer existed since day one, but it required manual handling of image graphics object, size limitations and configuration toggles.
Additionally the change to use GDI text rendering in 18.104.22.168 broke2 the most common code used for generating image with HTML Renderer, as provided in several blogs and StackOverflow answers3.
That's a long title that perfectly captures another issue I have found with GDI+ text rendering.
While checking Kris's claim on text rendering using GraphicsPath1 I have noticed that GDI+ text rendering using TextRenderingHint.AntiAlias looks much better (less fuzzy) in simple tests than the result of using HTML Renderer to generate transparent image (using AntiAlias hint). It's strange as HTML Renderer uses the same GDI+ text rendering method.
