I've created a grid and points in QGIS which I used to survey. Using a test image at the moment and I'm trying to fit this image as an overlay within a boundary. When I insert the image it has a white background which I can't remove in QGIS.
Image 1 is what the area looks like, I want to get the survey results inside the red line. Image 2 is what happens when I insert the image, the inserted image of the geophysical results is a .BMP file, the same happens with .TIFF files.
The image is moved into place by georeferencing corners of the boundary area or points on the grid.
