Detailed Description

Class definition of method frame for M output N input pixel pixel operations.

First we determine the broadest signature and supremum of sizes of all source images. The sources images are prepared to match that signature and sizes.

The number of result images is determined by calling HxImageData::probeMNpo. Result images will be allocated with the same size as the source images. The type of the result images is obtained from the HxImgFtorRuleBase via

resulttype of mnpo<broadest,mnpoName>
