About masking and blending width or height
Offset is used to clip the image on one or multiple sides (masking). This is used to hide parts of the picture that should not be shown
on the screen. For example: if the source is a Windows PC, you can hide the menu bar using this method.
The larger the Mask value, the more the image is masked (by black bar) at the corresponding side. E.g. Top mask of 100 will blank
the top 100 lines.
Height or width is used to create a blending zone with a smooth brightness drop off. This is used to compensate for the double
brightness in overlap areas. The value is the size of the blended area in pixels.
