Detailed Description

Decoder for U4 images with LZW compression. Like raw images, the data is just a stream of pixel data with no palette information (e.g. title.ega, tree.ega). This decoder handles the original 4-bit images, as well as the 8-bit VGA upgrade images.

Member Function Documentation

◆ loadStream()

bool Ultima::Ultima4::U4LzwImageDecoder::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.

See also: getSurface; getPalette
