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 to it when the offset is set. See SetColorOffsetA and SetColorOffsetB for more details.

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.
