Detailed Description

Class definition of method frame for resizing of image.

The method frame is used when the resulting image has a different size than the operand image.

result() will point to an empty image with the signature of src and the specified sizes. In case the signature of argImg is not equal to the signature of src a temporary image with that signature will be created for argument() with the same pixel values as argImg.
