Summary0011597: Lack of complementarity between Set() and Get() methods in PixelAccessors
DescriptionImageAdaptors use PixelAccessors to present an image as if it has been processed by a filter, but by doing the computation on the fly as the pixel value is accessed.

Ideally the behavior should be such that

imageAdaptor->SetPixel(index, A );
B = imageAdaptor->GetPixel(index);
A == B

Some ImageAdaptors / PixelAccessors are not satisfying this property.
