An update on my work on generating thumbnails for web pages:
I solved my problem by writing a custom QQuickItem that, when updated,
renders the webview into a FBO and saves the contents of that FBO to a
file. The WebviewThumbnailer (as I named it) is not updated by default,
it has to be requested explicitly. I’ve implemented it in the Ubuntu
Touch web browser. For those interested, see the code here:
I recently found out about this:
http://qt-project.org/doc/qt-5.0/qtquick/qml-qtquick2-shadereffectsource.html
It doesn't save the image to a file, but it might still help you.
Yes, I initially toyed with the ShaderEffectSource. However, as you’re
pointing out, there is no way to save the image to a file, hence my
custom solution, which essentially is a very simplified version of
ShaderEffectSource that renders the source item to an FBO and dumps the
contents of this FBO to an image file when requested.
