Affect

  The transformation can affect the Layer, the Selection, and the Path differently. These three buttons associate the remainder of the options to one of those three elements.

Transform Direction

  Forward (Traditional): Performs transformation according to the direction of grid lines: if grid is bent 10° to the left then the image will be bent 10° to the left too.

  Backward (Corrective): Performs transformation in the reverse direction of grid lines: if grid is bent 10° to the left then the image will be bent 10° to the right and so will be set upright. This option is used to correct perspective deformations. You bend grid lines to align them on the image lines that you want straighten up then you click Transform in the Info Window. You can have to clip the image after this transformation.

Interpolation

  The Interpolation drop-down list allows you to choose the quality of the transformation. For more information about the different methods that can be employed, see the glossary entry Interpolation.

Clip Result
