SRL::VDP2::ColorOffset Struct Reference

Detailed Description

Data structure of a VDP2 color offset to be set in Offset A or Offset B.

The offset data that will be set is a signed 9 bit value per color channel. The valid range of inputs is -255 to +255. The sign determines whether the color offset is additive or subtractive. Values outside the range will be clamped on initialization. See SetColorOffsetA and SetColorOffsetB for more details.
