I found two Raster Editors.
The first one is Serval Plugin and another one is Editor Raster in SCP of QGIS. Editor Raster is working not well for me and Serval can edit only single pixel per time. However, I need to edit raster in a thousand of pixel.
So could you please recommend me some tool in QGIS that I can edit faster or kind of brush editor in QGIS?
