Detailed Description

Class definition of method frame for multi 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.

A result image will be allocated with the same size as the source images. The type of the result image is obtained from the HxImgFtorRuleBase via

resulttype of mpo<broadest,mpoName>
