Is there any c++ API or anyway to render html pages on SkBitmap or SkCanvas?

What do you mean by "render"? You give it an HTML string (<!doctype html><div>hello</div>) and it outputs a screenshot of the rendered document (a bitmap of the word "Hello" printed, black on white, with 5 pixels of padding)?
If so, no - Blink is used to parse and render HTML.
Otherwise, please, elaborate.

Right, there is no API that converts HTML to SkCanvas/SkBitmap explicitly anywhere in blink or chromium. But in principle it's not hard to hack chromium to generate such a thing. There is code in the cc system that generates a single large SkPicture from a display item list (in the new world of Slimming Paint) and you can trivially play that SkPicture into any SkCanvas (in fact, it is a subclass of SkCanvas). You need to define the viewport appropriately to get all the content. One place to look for code that sort of does this is the rasterize_and_record benchmark.
There are also JS APIs exposed by certain flags(--enable-gpu-benchmarking and something about skia debugging) that allow you to dump a set of SkPictures representing the page. The Skia team uses this to generate their regression testing archives. You can then write something to load in the SkPictures and convert to a bitmap. The Skia team might have that already.
Stephen.

On android you can achieve pretty much what you ask using WebVIew's capturePicure. Not sure that fits your case then.

Dear Primiano
I know this may be very off topic to what is being discussed right now but I must ask you something.
