I just confirmed this with a snippet of code:
Works:
Image {
width: 100
height: 100
sourceSize: Qt.size(width, height)
source: "/image.png"
}
Works:
Image {
width: 100
height: 100
sourceSize: Qt.size(width, height)
source: "image://thumbnailer/file:///image.png"
}
Works:
Image {
width: 100
height: 100
sourceSize: Qt.size(width, height)
source: "qrc:///image.png"
}
Fails:
Image {
width: 100
height: 100
sourceSize: Qt.size(width, height)
source: "image://thumbnailer/qrc:///image.png"
}
This throws the following error:
Thumbnailer: RequestImpl::dbusCallFinished(): D-Bus error:
DBusInterface::GetThumbnail(): ap.png: unity::ResourceException:
Thumbnailer::get_thumbnail():
boost::filesystem::canonical: No such file or directory: "/image.png"
qrc:///Main.qml:19:5: QML QQuickImage: Thumbnailer:
RequestImpl::dbusCallFinished(): D-Bus error: DBusInterface::GetThumbnail():
ap.png: unity::ResourceException: Thumbnailer::get_thumbnail():
boost::filesystem::canonical: No such file or directory: "/image.png"
=> As stated before, putting media into a qrc file is the way the
default template in the SDK suggests to do it (in order to not bother
the developer with finding the apparmor confined paths on the phone) and
thus should probably also work with the thumbnailer.
As the thumbnailer is remote process and thus won't have access to the
in-binary resources files, the QQmlImageProvider could perhaps extract
them from the binary, provide them to the thumbnailer and delete the
temporarily extracted original file again.

Title:
Thumbnails not working with qrc
Status in Client Developer Experience:
New
Status in thumbnailer package in Ubuntu:
New
Bug description:
The thumbnailer works only if I load images from the file system, not
from a resource file:
Image {
id: backgroundImage
anchors.fill: parent
sourceSize: Qt.size(parent.width, parent.height)
source: "image://thumbnailer/qrc:///images/menu-background.jpg"
}
The default sdk template uses qrc as template.
