C Specification

The XrCompositionLayerColorScaleBiasKHR structure is defined as:

// Provided by XR_KHR_composition_layer_color_scale_bias
typedef struct XrCompositionLayerColorScaleBiasKHR {
    XrStructureType    type;
    const void*        next;
    XrColor4f          colorScale;
    XrColor4f          colorBias;
} XrCompositionLayerColorScaleBiasKHR;


Member Descriptions
  • type is the XrStructureType of this structure.

  • next is NULL or a pointer to the next structure in a structure chain. No such structures are defined in core OpenXR or this extension.

  • colorScale is an XrColor4f which will modulate the color sourced from the images.

  • colorBias is an XrColor4f which will offset the color sourced from the images.


XrCompositionLayerColorScaleBiasKHR contains the information needed to scale and bias the color of layer textures.

The XrCompositionLayerColorScaleBiasKHR structure can be applied by applications to composition layers by adding an instance of the struct to the XrCompositionLayerBaseHeader::next list.
