[webkit-help] Image save and repainting inside webkit

[ankit srivastav]

Hi Max

Thanks for your reply.

But may be you took the question into a different direction. We are trying
to make changes into Webkit code, so that the functionality works for each
and every application/Webpage.

We have to achieve two things:
1) An event {from within the webkit} when the whole Web Page is rendered.
2) To Store images, so that after page gets rendered ,we can repaint them
again after doing some modifications.

The problem is- Is it possible to repaint only the saved images again ?
And if yes is their any way to do that.

TIA..

There is no real concept of "the full page is rendered" in a web engine.
From the engine perspective, once a page has started its execution, it
is live until the page is destroyed.

The closest you will find to a page being "ready" comes from the layout
milestones.
Look LayoutMilestoneFlag in WebCore.
DidFirstPaintAfterSuppressedIncrementalRendering may be the easiest for
what you are trying to do.

After you replaced the image buffer, use imageChanged().

Hi All,

Working on a webkit DRT test case media/video-canvas-drawing-output.html .
Test is getting failed on Win environment with only 1 pixel value
difference.
But is working fine on linux.
Is this test should be added in the skipped list for windows ?
Is their is some difference in clourspace management on win and Linux
environment ?

TIA.
