@ -18,24 +18,39 @@ to fit the styles and available data (OpenMapTiles, Mapbox tiles).
Due to a major design flaw in the Mapbox vector tiles specification - the zoom
is not part of the PBF data - the plugin can not be used "as is", but passing
the zoom level is necessary. This is done by exploiting the optional *format*
parameter of the QImage constructor or the QImage::fromData() or
QPixmap::loadFromData() functions. The zoom number is passed as ASCII string
parameter of the QImage constructor or the *QImage::loadFromData()* or
*QPixmap::loadFromData()* functions. The zoom number is passed as ASCII string
to the functions:
```cpp
QPixmap pm;
pm.loadFromData(tileData, QString::number(zoom).toLatin1());
QImage img;
img.loadFromData(data, QByteArray::number(zoom));
```
The plugin supports vector scaling using QImageReader's setScaledSize() method,
For a complete code sample see the [pbf2png](https://github.com/tumic0/pbf2png)
conversion utility.
### HiDPI
The plugin supports vector scaling using QImageReader's *setScaledSize()* method,
so when used like in the following example:
```cpp
QImageReader reader(file, QString::number(zoom).toLatin1());
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).
For a sample code see the [pbf2png](https://github.com/tumic0/pbf2png)
conversion utility.
### Overzoom
Since version 3 of the plugin tile overzoom is supported. If you set *format*
to `$zoom;$overzoom`:
```cpp
QImage img;
QByteArray fmt(QByteArray::number(zoom) + ';' + QByteArray::number(overzoom));
img.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.
