to the functions:
```cpp
QPixmap pm;
pm.loadFromData(tileData, QByteArray::number(zoom));
pm.loadFromData(data, QByteArray::number(zoom));
```

The plugin supports vector scaling using QImageReader's setScaledSize() method,
so when used like in the following example:
```cpp
QImage img;
QImageReader reader(file, QByteArray::number(zoom));
reader.setScaledSize(QSize(1024, 1024));
reader.read(&image);
reader.read(&img);
```
you will get 1024x1024px tiles with a pixel ratio of 2 (= HiDPI tiles).
@ -44,8 +45,8 @@ Since version 2.7 tile overzoom is supported. If you set *format* to
`$zoom;$overzoom`:
```cpp
QPixmap pm;
pm.loadFromData(tileData, QByteArray::number(zoom) + ';' +
QByteArray::number(overzoom));
QByteArray fmt(QByteArray::number(zoom) + ';' + QByteArray::number(overzoom));
pm.loadFromData(data, fmt);

you will get (512<<overzoom)x(512<<overzoom)px tiles with a pixel ratio of 1.
When overzoom is combined with setScaledSize(), the base size is the overzoomed
