Variable Edge Blending

Variable Edge Blending parameters are used in conjunction with the Collage Generator
parameters and allow for on-the-fly adjustment of blend overlap between projectors. These
parameters allow more flexibility for sizing a collage to a given screen or projection surface, as
well as smoother blending if wider blend regions are used. Horizontal and vertical blend regions
can be controlled independently of one another.
The Variable Edge Blend Horizontal parameters allow 16-bit control of the horizontal blend
region width from 0% (hard edge) up to 50% of the image size. The default fixture library value
has been chosen to give a 9% overlap, this starting value is adjustable based on your specific
installation.
The Variable Edge Blend Vertical parameters allow 16-bit control of the vertical blend region
width from 0% (hard edge) up to 50% of the image size. The default fixture library value has
been chosen to give a 9% overlap, this starting value is adjustable based on your specific
installation.
