-### HiDPI
 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(&img);
+reader.read(&image);
 ```
 you will get 1024x1024px tiles with a pixel ratio of 2 (= HiDPI tiles).
 
-### Overzoom
-Since version 3 of the plugin tile overzoom is supported. If you set *format*
-to `$zoom;$overzoom`:
-```cpp
-QPixmap pm;
-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
-tile size.
