This method adds inputImage to the BlendingBuffer with inputImageWeights. inputImage pel�fs contribution to the result image is weighted with the contribution of inputImageWeights pels that corresponded to the same pel in the result image. inputImageWeights can be null. In this case, all input pels are weighted fully and equally.

This method allows user to do both masking and weighting. inputImageMask must be non-null and allocated, but does not need to be the same size as the input image. VisionPro assumes that image pels not covered by the mask are care pixels (i.e.they are copied into the destination) inputImageMaskOffsetX/Y can be any integer value. These values specify how the mask is aligned on the image. (Same as other VPro tools with masking.).
