List of all members.

Public Methods
	PixelFormatRGBABits (int depth, unsigned int redMask, unsigned int greenMask, unsigned int blueMask, unsigned int alphaMask)
virtual Image	filter (const Image &image)
	Return an Image in this format.
void	fromGrayChar (const Image &image, Image &result) const
void	fromGrayFloat (const Image &image, Image &result) const
void	fromGrayDouble (const Image &image, Image &result) const
void	fromRGBAChar (const Image &image, Image &result) const
void	fromRGBABits (const Image &image, Image &result) const
virtual bool	operator== (const PixelFormat &that) const
	Checks if this and that describe the same actual format.
virtual unsigned int	getRGBA (void *pixel) const
	Return value is always assumed to be non-linear sRGB. Same for other RGB methods below.
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	setAlpha (void *pixel, unsigned char alpha) const
	Ignored by default. Formats that actually have an alpha channel must override this method.
void	shift (unsigned int redMask, unsigned int greenMask, unsigned int blueMask, unsigned int alphaMask, int &redShift, int &greenShift, int &blueShift, int &alphaShift) const

Image PixelFormatRGBABits::filter (  const Image &    image )  [virtual]

Return an Image in this format. Reimplemented from fl::PixelFormat.

void PixelFormatRGBABits::fromGrayChar (  const Image &    image, Image &    result )  const

void PixelFormatRGBABits::fromGrayDouble (  const Image &    image, Image &    result )  const

void PixelFormatRGBABits::fromGrayFloat (  const Image &    image, Image &    result )  const

void PixelFormatRGBABits::fromRGBABits (  const Image &    image, Image &    result )  const

void PixelFormatRGBABits::fromRGBAChar (  const Image &    image, Image &    result )  const

unsigned char PixelFormatRGBABits::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.

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

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

bool PixelFormatRGBABits::operator== (  const PixelFormat &    that )  const [virtual]

Checks if this and that describe the same actual format. Reimplemented from fl::PixelFormat.

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

Implements fl::PixelFormat.

void PixelFormatRGBABits::shift (  unsigned int    redMask, unsigned int    greenMask, unsigned int    blueMask, unsigned int    alphaMask, int &    redShift, int &    greenShift, int &    blueShift, int &    alphaShift )  const
