Member Function Documentation

decodeFrame()

const Graphics::Surface* Image::CinepakDecoder::decodeFrame ( Common::SeekableReadStream &  stream )

overridevirtual

Decode the frame for the given data and return a pointer to a surface containing the decoded frame.

Returns

a pointer to the decoded frame

Implements Image::Codec.

getPixelFormat()

Graphics::PixelFormat Image::CinepakDecoder::getPixelFormat ( ) const

inlineoverridevirtual

Get the format that the surface returned from decodeImage() will be in.

Implements Image::Codec.

setOutputPixelFormat()

bool Image::CinepakDecoder::setOutputPixelFormat ( const Graphics::PixelFormat &  format )

overridevirtual

Select the preferred format to use, for codecs where this is faster than converting the image afterwards. Returns true if supported, and false otherwise.

Reimplemented from Image::Codec.

containsPalette()

bool Image::CinepakDecoder::containsPalette ( ) const

inlineoverridevirtual

Can this codec's frames contain a palette?

Reimplemented from Image::Codec.

getPalette()

const byte* Image::CinepakDecoder::getPalette ( )

inlineoverridevirtual

Get the palette last decoded from decodeImage

Reimplemented from Image::Codec.

hasDirtyPalette()

bool Image::CinepakDecoder::hasDirtyPalette ( ) const

inlineoverridevirtual

Does the codec have a dirty palette?

Reimplemented from Image::Codec.

canDither()

bool Image::CinepakDecoder::canDither ( DitherType  type ) const

overridevirtual

Can the codec dither down to 8bpp?

Reimplemented from Image::Codec.

setDither()

void Image::CinepakDecoder::setDither ( DitherType  type, const byte *  palette  )

overridevirtual

Activate dithering mode with a palette

Reimplemented from Image::Codec.
