  %  TransformRGBImage() converts the reference image from an alternate
  %  colorspace to sRGB.  The transformation matrices are not the standard ones:
  %  the weights are rescaled to normalize the range of the transformed values to
  %  be [0..QuantumRange].
  %
  %  The format of the TransformRGBImage method is:
  %
  %      MagickBooleanType TransformRGBImage(Image *image,
  %        const ColorspaceType colorspace)
  %
  %  A description of each parameter follows:
  %
  %    o image: the image.
  %
  %    o colorspace: the colorspace to transform the image to.
