8.8 Blending & masking
About Blending & Masking
Blending is used in multi channel installation to have a seamless transition between the channels. Image
blending gives the appearance of a single view, thus achieving realistic immersion for the majority of wide
screen applications.
The principle is that the light intensity in the blend zone from each projector will be adjusted individually, so
that the rendering on the screen are perceived as from one projector.

From the start (mask) position, you can blend zone size per edge (left, top, right, bottom). For each edge there
will be a drop-off curve for the blend zone.

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.
