The relative width can be derived using elementary trigonometry to be 1/cos(tiltangle). This processor should hence probably be called OneOverCosineWeightingProcessor. You can specify the angle explicitly (which is the default behavior), or you can force the angle to be the altitude angle as derived from the EMData metadata. The processor could obviously be made more robust if the angle derived from the EMData header could be specified...
angle | The angle that the image is, with respect to the zero tilt image | |
angle_fim | Read fim as 'from image metadata' - this causes the altitude angle stored in by the image object (i.e. as extracted from the header, as currently stored in memory) to be used as the angle. This overrides the angle argument |

Get the descrition of this specific processor. This function must be overwritten by a subclass.

Get the processor's name. Each processor is identified by a unique name.

Get processor parameter information in a dictionary. Each parameter has one record in the dictionary. Each record contains its name, data-type, and description.

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.
