I have a distorted raster of a historic map that I need to warp to match the modern map. I've installed the plugin Raster Blender, but I can't work out how to use it, and can find no instructions online. How do I set up the pairs of points for it to use to warp the raster? If there is an alternative method for QGIS 3, that would do. I have both versions.
