Bug 38554 – [Qt] The image plugin used for decoding images should be configurable

• Status: RESOLVED
• Resolution: INVALID
• Component: WebKit API

[Benjamin Poulain]

Currently, all the images plugins can be used to decode images.

That can be a security issue, one might want to avoid some image formats when decoding images from the Web: Tiff, SVG (see https://bugs.webkit.org/show_bug.cgi?id=37826), mng for example.

We could add an API in QWebSettings to name explicitly the plugins that can be loaded:
QWebSettings::disableAutoImageLoading()
QWebSettings::enableImagePlugin("jpg");

Initial implementation of configurable images loading.

Add initial implementation of configurable images auto loading.
Right now i am just handling png and jpeg and the public api will be changed.

this could be called outside the loop.

page->settings()->loadsSiteJPEGImagesIgnoringImageLoadingSetting()

Ditto

& positioned wrong.

The goal should be clean, and comments are needed.

Only caring about these two formats?
