Member Function Documentation

destroy()

void Supernova::MSNImage::destroy ( )

overridevirtual

Destroy this decoder's surface and palette.

This should be called by a loadStream() implementation as well as by the destructor.

Implements Image::ImageDecoder.

loadStream()

bool Supernova::MSNImage::loadStream ( Common::SeekableReadStream &  stream )

overridevirtual

Load an image from the specified stream.

loadStream() should implicitly call destroy() to free the memory of the last loadStream() call.

Parameters

stream

Input stream.

Returns

Whether loading the file succeeded.

getSurface

getPalette

Implements Image::ImageDecoder.

getSurface()

const Graphics::Surface* Supernova::MSNImage::getSurface ( ) const

inlineoverridevirtual

Get the decoded surface.

This surface is owned by this ImageDecoder and remains valid until destroy() or loadStream() is called, or until the destructor of this ImageDecoder is called.

Returns

The decoded surface, or 0 if no surface is present.

Implements Image::ImageDecoder.

getPalette()

const Graphics::Palette& Supernova::MSNImage::getPalette ( ) const

inlineoverridevirtual

Get the decoded palette.

This palette is owned by this ImageDecoder and remains valid until destroy() or loadStream() is called, or until the destructor of this ImageDecoder is called.

Returns

The decoded palette, or empty if no palette is present.

Implements Image::ImageDecoder.
