There has lots of customers who need to convert HTML to image on Linux system,  please refer to their questions at below,
---------------------------------------------------

Is there a ready to use program (that I can run from my web application) to convert html file to image (using for example webkit) ?

I need convert HTML background to image too, is there any program that do this properly?
---------------------------------------------------
How can I convert a CSS3 or CSS2-based HTML page into a JPEG or PNG (with transparent background) image?

Is there any command-line tool or php-based API that can be installed on my Linux server and provide me with the best result possible?
---------------------------------------------------
If your goal is to make a picture of what the page would look like in a browser, you need an HTML rendering engine (one of a browser's main parts) for that.

PHP doesn't have one of those built-in, but you could use VeryPDF Cloud API (html2image API) to do the rendering.

---------------------------------------------------
Nothing to do with rendering an individual image on a webpage. Goal is to render the entire webpage save that as a screenshot. Want to show a thumbnail of an HTML file to the user. The HTML file I will be screenshotting will be an HTML part in a MIME email message - ideally I would like to snapshot the entire MIME file but if I can do this to an HTML file I'll be in good shape.

An API would be ideal but an executable is also good.
---------------------------------------------------

I need a tool to automatically convert simple HTML into an image. I will be controlling the HTML input which will consist of simple text formatting tags and possibly image links. I don't need to be able to render arbitrary HTML. Is there a simple way to do this?

I've looked at the HTML layout engines like Gecko and Webkit, but frankly I'm overwhelmed by the number of options they have--I don't need a complete web browser! Is it possible to use these engines in this way? Can someone steer me in the right direction?

Other possibilities like browser shots, rely on screenshots of real browsers, but I'm going to be running this application on a web server with potentially many users so performance is important and I'm afraid this kind of solution won't scale.

Ideas?

EDIT: Sorry forget to mention that my server is running Linux, so Windows solutions won't help. 🙂
---------------------------------------------------
