How to get pictures from QWebView

Question

Does anybody know how to get a picture from qwebview? My situation is, there is no scope to use the image url and then a QNetworkRequest. I just need to 'extract' the image from the QWebview.

What do you mean with "get a picture"? Getting a screenshot of the page? A screenshot of a portion of the page? Downloading an image contained in the DOM? – Lyrate

I want to get an image which is in the view. For example, the image of <img src="path" /> This image without redownloading it, just from the view. If it don't work, then screenshot of a portion will do. – Unmoral

First you need to get the QWebElement with the image you want to save - if you don't have it already, a good way to get it is

QWebElement el = view.page()->mainFrame()->findFirstElement("IMG[src='path/to/img'");

assuming view is the name of your QWebView. Then,

QImage image(el.geometry().width(), el.geometry().height(), QImage::Format_ARGB32);
QPainter painter(&image);
el.render(&painter);
painter.end();
image.save("path/to/img.png");

el.geometry().width(), el.geometry().height() could be replaced with el.geometry().size() – Bangweulu
