I have loaded and scaled an image

	if (IGraphics->CompositeTags(
		COMPOSITE_Src,						OrigBM, ScaleBM,
		COMPTAG_ScaleX,						COMP_FLOAT_TO_FIX(ScaleFactorX),
		COMPTAG_ScaleY,						COMP_FLOAT_TO_FIX(ScaleFactorY),
	TAG_DONE) != COMPERR_Success)
	{
		if (ScaleBM != NULL)
			IP96->p96FreeBitMap(ScaleBM);
	}

I would like to give it a "ghosted/disabled" look. I added
COMPTAG_SrcAlpha,COMP_FLOAT_TO_FIX(0.75),
It looks ok on some images/colors, but terrible with white images.

Just like when you open Workbench window and do Show All and the C/Devs/S folders are ghosted.

Something simple that can be done on the fly quickly.
