## Install
Copy the plugin to the system Qt image plugins path to make it work. You may
also set the QT_PLUGIN_PATH system variable before starting the application. For
Linux, there are RPM and DEB [packages](https://build.opensuse.org/project/show/home:tumic:QtPBFImagePlugin)
also set the QT_PLUGIN_PATH system variable before starting the application.
For Linux, there are RPM and DEB [packages](https://build.opensuse.org/project/show/home:tumic:QtPBFImagePlugin)
for most common distros available on OBS.
## Limitations
* Only data that is part of the PBF file is displayed. External layers defined in the
style are ignored.
* Text PBF features must have a unique id (OpenMapTiles >= v3.7) for the text layout
algorithm to work properly.
* Expressions are not supported in the styles, only property functions are implemented.
* Only data that is part of the PBF file is displayed. External layers defined
in the style are ignored.
* Text PBF features must have a unique id (OpenMapTiles >= v3.7) for the text
layout algorithm to work properly. Additionally, the tile buffer must be large
enough to contain all neighboring text features overlapping to the tile bounds
(only data from the tile itself can be drawn to the resulting image).
* Expressions are not supported in the styles, only property functions are
implemented.
