Ghost an image
I have loaded and scaled an image 
  1. 	if (IGraphics->CompositeTags(
  2. 		COMPOSITE_Src,						OrigBM, ScaleBM,
  3. 		COMPTAG_ScaleX,						COMP_FLOAT_TO_FIX(ScaleFactorX),
  4. 		COMPTAG_ScaleY,						COMP_FLOAT_TO_FIX(ScaleFactorY),
  5. 	TAG_DONE) != COMPERR_Success)
  6. 	{
  7. 		if (ScaleBM != NULL)
  8. 			IP96->p96FreeBitMap(ScaleBM);
  9. 	}
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.
