Bug 118500 – [WK2][CoordinatedGraphics] Conform transforming functions to their names.

• Component: WebKit EFL
• Status: NEW

[Eunmi Lee]

The transforming functions in the WebView do not transform correctly.

The transformToScene() function scales the content position with content scale factor even though it is already scaled value.
The userViewportToContents() function transforms scene position instead of user-viewport position to the contents position.
The contentsToUserViewport() function transforms contents position to scene instead of user-viewport.

The scene position indicates the position in the window (Evas in the EFL), and the user-viewport position indicates the position in the web view (Evas_Object in the EFL).
The scene and user-viewport are different, so they should not be confused.

Agree with Kenneth, there should be a test showing the current problem in browser behaviour (it exists, right? since you're fixing it) and that this problem is solved after the patch is applied.

I'm sorry but I can not make test for this problem now, because I've found this problem while making gestures.
The gestures does not work correctly without this patch especially, scaling gesture using double tap.

I thought it is better that this patch is merged before gesture patch, so I made this patch.
Do I have to merge this patch after gesture patches?

I've made new bug for correcting wrong usage of m_contentPosition in the WebView - Bug 118548,
So, I will update patch for this bug.

typo: anapplication.
In EFL port, the user viewport corresponds to Evas_Object(ewk_view) and the scene corresponds to Evas.
