Re: [Qgis-user] GDAL Fill nodata Algorithm
When i use QGIS 2.8 and open the Fill nodata Algorithm from Processing there are the following menus: Input layer, Search distance, Smooth iterations, Band to operate on, Validity mask, DO not use default validity mask, Filled. Are we talking about the same application?
