Detailed Description

Replace a source image as a circle or sphere depends on 2D or 3D of the source image.

Parameters:
radius radius of circle or sphere
axis specify a major axis for asymmetric features
c distance between focus and the center of an ellipse
fill answer 'yes' or 'no' to specify if it's filled or hollow, default filled

void TestImageCirclesphere::process_inplace ( EMData image  )  [virtual]

To process an image in-place.

For those processors which can only be processed out-of-place, override this function to just print out some error message to remind user call the out-of-place version.

Parameters:
image The image to be processed.
