I do Qml, so
// C++, expose the m_image_scale as a meta property
class MyApp : public QObject
{
Q_OBJECT
Q_PROPERTY(QString imageScale read imageScale CONSTANT)
public:
// MyApp init should extract the string scale as previously stated,
this function only returns the QString value.
QString imageScale() const;
};
// Qml
Image
{
// Here you can make yourself a method, a sub folder if you want or whatever
suites your needs.
source: "qrc:///image/myImageName" + MyApp.imageScale + ".png"
}
There's probably a better way to do it, but this I can track what is going on
without fiddling too much into obscure under the hood undocumented behavior and
the resource are inline with other iOS made images without too much renaming.

Please keep going...
How do you use m_image_scale ?
