Constructor & Destructor Documentation

DoodleDecoder()

Image::DoodleDecoder::DoodleDecoder

(

const byte *

palette

)

Constructor for the DoodleDecoder

Parameters

palette

Pointer to RGB palette data (16 colors * 3 components)

Member Function Documentation

loadStream()

bool Image::DoodleDecoder::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.

destroy()

void Image::DoodleDecoder::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.

getSurface()

const Graphics::Surface* Image::DoodleDecoder::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& Image::DoodleDecoder::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.

loadStreams()

bool Image::DoodleDecoder::loadStreams	(	Common::SeekableReadStream &	highresStream,
		Common::SeekableReadStream &	colorStream1,
		Common::SeekableReadStream &	colorStream2
	)

Load a C64 doodle image from its component streams

Parameters

highresStream	Stream containing high-resolution pixel data
colorStream1	Stream containing first color data file
colorStream2	Stream containing second color data file

Returns

Whether loading succeeded
