[Qgis-user] Composer Scale

Hi Ahmad,

Did you build pyramids on your raster data to improve the performance?

Double click the raster layer and the layer properties dialogue opens.
Then in the left iconbar go to "Pyramids". On the bottom right you can use
the "Build Pyramids" button. If you already have pyramids, you will see
them listed here.

Hope this helps,
Andreas
