PySide2.QtQuick.QQuickImageResponse

Implement this method to return the job that will provide the texture with id .

The id is the requested image source, with the “image:” scheme and provider identifier removed. For example, if the image source was “image://myprovider/icons/home”, the given id would be “icons/home”.

The requestedSize corresponds to the Image::sourceSize requested by an Image item. If requestedSize is a valid size, the image returned should be of that size.
