messageSize (4 bytes): A 32-bit unsigned integer. The size of this message in bytes. The value of this field MUST be set to 0x00000010.
controlCode (4 bytes): A 32-bit unsigned integer containing the control code for this message. The value of this field MUST be equal to 0x00000025.
targetResource (4 bytes): A 32-bit unsigned integer. The value of this field MUST be set to a valid resource handle referencing a resource of type TYPE_VISUAL or TYPE_WINDOWNODE. This handle identifies the resource that is the target for this message.
hTransform (4 bytes): A 32-bit unsigned integer. The value of this field MUST either be set to zero or set to a valid resource handle referencing a resource of type TYPE_COLORTRANSFORMRESOURCE. If the hTransform field is nonzero, then this resource represents the transformation that is applied to each pixel of the final rasterization of this visual, before this visual is blended with the background. If the hTransform field is zero, then no color transformation is applied to the rasterization of this visual.
