I have PNG image exported from python script without any meta-data. I know coordinates of top-left corner and bottom-right corner and projection (I guess it's Mercator). How can I import this image to correct position?
To be sure, I know about Georeferencer in menu. However it seems like bad idea to resample original raster image. (I have to choose corner points manually, then enter target coordinates, and it's still not working.) Is there a way where I just enter 4 numbers and projection, and raster will appear on correct position in map? Or is it possible to somehow create metadata for this image so it will be imported automatically to correct position?
Edit: Ok, it is working when I manually set corners to correct pixel values and use Linear transformation. But it still seems like a bad solution. Adding some meta-data to image would be nicer.
