Inheritance diagram for fl::PixelFormatRGBAFloat:

List of all members.

Public Methods
	PixelFormatRGBAFloat ()
virtual unsigned int	getRGBA (void *pixel) const
	Return value is always assumed to be non-linear sRGB. Same for other RGB methods below.
virtual void	getRGBA (void *pixel, float values[]) const
	"values" must have at least four elements. Each returned value is in [0,1].
virtual unsigned char	getAlpha (void *pixel) const
	Returns fully opaque by default. PixelFormats that actually have an alpha channel must override this to return correct value.
virtual void	setRGBA (void *pixel, unsigned int rgba) const
virtual void	setRGBA (void *pixel, float values[]) const
	Each value must be in [0,1]. Values outside this range will be clamped and modified directly in the array.
virtual void	setAlpha (void *pixel, unsigned char alpha) const
	Ignored by default. Formats that actually have an alpha channel must override this method.

Member Function Documentation

unsigned char PixelFormatRGBAFloat::getAlpha (  void *    pixel )  const [virtual]

Returns fully opaque by default. PixelFormats that actually have an alpha channel must override this to return correct value. Reimplemented from fl::PixelFormat.

void PixelFormatRGBAFloat::getRGBA (  void *    pixel, float    values[] )  const [virtual]

"values" must have at least four elements. Each returned value is in [0,1]. Reimplemented from fl::PixelFormat.

unsigned int PixelFormatRGBAFloat::getRGBA (  void *    pixel )  const [virtual]

Return value is always assumed to be non-linear sRGB. Same for other RGB methods below. Implements fl::PixelFormat.

void PixelFormatRGBAFloat::setAlpha (  void *    pixel, unsigned char    alpha )  const [virtual]

Ignored by default. Formats that actually have an alpha channel must override this method. Reimplemented from fl::PixelFormat.

void PixelFormatRGBAFloat::setRGBA (  void *    pixel, float    values[] )  const [virtual]

Each value must be in [0,1]. Values outside this range will be clamped and modified directly in the array. Reimplemented from fl::PixelFormat.

void PixelFormatRGBAFloat::setRGBA (  void *    pixel, unsigned int    rgba )  const [virtual]

Implements fl::PixelFormat.
