I'm working with sets of aerial images in QGIS which are geocoded including orientation i.e. rotated.
After loading images QGIS draws a black box around each image that extends from the far west to far east pixel and from the far north to far south pixel. Within this black box lays the actual image in it's correct orientation.
To get rid of this black box I currently enter 0 in Layer Properties / Transparency / Additional NODATA value but the change has to be made on every single image. Unfortunately the transparency setting is not part of the Style definition and therefore cannot be copied from one to all other raster layers / images.
Is there better way to add a global NODATA value to all raster data in current workspace?
Raster Calculator won't work as there are no NODATA areas in the actual image files.
