fl::PixelFormat fl::Filter List of all members.

Public Methods

 PixelFormatRGBAChar ()
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 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.


Static Public Methods

void shift (unsigned int redMask, unsigned int greenMask, unsigned int blueMask, unsigned int alphaMask, int &redShift, int &greenShift, int &blueShift, int &alphaShift)
 Shifts are set to move bits from this format to the one indicated by the masks.

Image &    result
)  const
 

unsigned char PixelFormatRGBAChar::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 PixelFormatRGBAChar::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 PixelFormatRGBAChar::operator== (  const PixelFormat &    that )  const [virtual]
 

Checks if this and that describe the same actual format.

Reimplemented from fl::PixelFormat.

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

Implements fl::PixelFormat.

void PixelFormatRGBAChar::shift (  unsigned int    redMask,
unsigned int    greenMask,
unsigned int    blueMask,
unsigned int    alphaMask,
int &    redShift,
int &    greenShift,
