I am trying to use QGIS and the Georeferencer to digitize paper maps but I am unable to get the raster to rotate afte I pick my control points. Below is a brief outline of the steps I used to transform my raster.

  1. Added two control points and picked corresponding points in map canvas.

  2. The transformation type is set to Helmert

  3. Resampling method: Cubic

  4. Compression: Deflate

  5. Specified Output file name

  6. Checked "Load in Qgis...", then Ok

  7. Then clicked run button.

The attached image is the results in QGIS.

enter image description here

The image should be much smaller
