+The parameters are \texttt{xsize}, \texttt{ysize}, and \texttt{interpolation}.
+The \texttt{xsize} and \texttt{ysize} parameters set the size of the 
+resulting image file. The \texttt{interpolation} parameter selects the
+interpolation method. Currently, the \texttt{bilinear} option provides
+the highest quality interpolation.

+\subsection{Process - Convert FFT Polar Dialog}
+The paramters for this option are the same as 
+\helprefn{convertpolardialog}{Convert Polar Dialog}. For this command,

+polar image.

+This dialog sets the parameters for reconstructing an image from projections
