Figure 2-17 Edge Blending
This raises the intensity of the pixels on the edges of the physical screens
so that the overall projected image is consistently bright. These blending
options are only meaningful in multi-channel configurations. The default
is to not enable screen blending
SlsScreenBlendOffsetPixels is similar to SlsScreenBlendOffsetPercent,
except you specify the exact number of pixels to blend instead of a
percentage of the screen width. Specify either pixels or a percentage.
These two options are mutually exclusive.
configuring offset overlap for multiple rows
The previous edge-blending example shows a simple three-channel con-
figuration with one row and blending between the three columns. For
blending of multiple rows, also add one of the following ScreenOptions to
specify the amount of each screen to use for blending between the rows:
SlsScreenBlendHeightPercent <percent>
SlsScreenBlendHeightPixels <pixels>
Example:
SlaveLayout
Rows 2
Columns 2
