14.6.3 CMD_SetEdgeBlendingConfiguration [Command ID: 0x3E]

This command sets projector overlap and geometric correction parameters for manual edge blending. It creates and applies blending and warping maps for given blending inputs. It is necessary to separately call commands to enable manual warping and enable edge blending for the results to take effect.

Overlaps with adjacent projectors must be specified in pixels. There is a single value for horizontal overlap, and a single value for vertical overlap. This means overlaps between all projectors for a given direction (horizontal or vertical) must be identical. Overlaps set to zero cause no blending to occur. Temporarily keeping the overlaps to zero can be useful for initial geometric adjustments.

Storage Options provides the capability to store the configuration to nonvolatile storage, and to enable application of the stored blending configuration at startup. The stored information includes that provided through both CMD_SetEdgeBlendingConfiguration and CMD_SetEdgeBlendinSystemParams. Changes to Storage Options can be made using any valid blending configuration, including the trivial case of no blending: 1x1 system, zero overlaps, no geometric correction.

Geometry parameters are dependent on geometric adjustment type. The options for geometric adjustment type are keystone corners or no geometric correction. For no geometric correction, no additional parameters are required. When using Simple 1D RGB mode, no geometric correction should be used.
