@ -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.
