Detailed Description

transform kartesian to poloar coordinates

Available PostProcessors:: "202":transform kartesian to poloar coordinates

This processor transforms the kartesian coordinates of an image to its polar representation. It transforms the phi, r to kartesian coordinates to find the pixel in the image that the r,phi values corrospond to. It will do a 2D interpolation to be able to weight the content of the pixel correctly. The weighing factor is determined from the distance that the transformed kartesian coordinates have from the neighboring pixels. 0 deg is up.

See also: Processor for a list of all commonly available cass.ini settings.

User definable Parameters:

Processor/%name%/{ImageName}
The name of the Processor that contains the image that the angluar distribution should be retrieved from.

Processor/%name%/{ImageXCenter|ImageYCenter}
values for the center of the image. Default is 500,500

Processor/%name%/{NbrAngularPoints}
The number of Bins along the phi axis in the resulting histogram. Default is 360.

Processor/%name%/{NbrRadialPoints}
The number of Bins along the r axis in the resulting histogram. Default is 500.
