Member Function Documentation

◆ destroy()

void Director::DIBDecoder::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 Director::DIBDecoder::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
streamInput stream.
Returns
Whether loading the file succeeded.

getSurface
getPalette

Implements Image::ImageDecoder.

◆ getSurface()

const Graphics::Surface* Director::DIBDecoder::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 byte* Director::DIBDecoder::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.

The format of the palette is the same as that of the PaletteManager's palette. (interleaved RGB values).

Returns
The decoded palette, or undefined if no palette is present.

Reimplemented from Image::ImageDecoder.

◆ getPaletteColorCount()

uint16 Director::DIBDecoder::getPaletteColorCount ( ) const
inlineoverridevirtual

Return the number of colors in the palette.

Reimplemented from Image::ImageDecoder.
