This plugin allows to apply a similarity transformation (rotation, translation and isotropic scaling) to a 2D image in an interactive way.

Premises: You need an image to be open.


  1. When calling the plugin, two points (represented as yellow PointRois) will be displayed on the image.
  2. Drag and drop the points to interactively transform the image with a similarity model (rotation, translation and isotropic scaling).
  3. If you are satisfied with the result, press ENTER, otherwise, press ESC.
