Detailed Description

Utility class for decoding Theme Hospital "chunked" graphics files. Generally used internally by sprite_sheet.

Constructor & Destructor Documentation

chunk_renderer::chunk_renderer	(	int	width,
		int	height,
		std::vector< uint8_t >::iterator	start
	)

Initialise a renderer for a specific size result.

Parameters

width	Pixel width of the resulting image
height	Pixel height of the resulting image
start	An iterator to the start writing the resulting image to. Must point to a container of at least width * height.

void chunk_renderer::chunk_copy	(	int	npixels,
		const uint8_t *	in_data
	)

Perform a "copy" chunk (normally called by decodeChunks)

void chunk_renderer::chunk_fill	(	int	npixels,
		uint8_t	value
	)

Perform a "fill" chunk (normally called by decodeChunks)

void chunk_renderer::chunk_fill_to_end_of_line ( uint8_t value )

Perform a "fill to end of line" chunk (normally called by decodeChunks)

void chunk_renderer::chunk_finish ( uint8_t value )

Perform a "fill to end of file" chunk (normally called by decodeChunks)

void chunk_renderer::decode_chunks	(	const uint8_t *	pData,
		int	iDataLen,
		bool	bComplex
	)

Convert a stream of chunks into a raw bitmap.

Parameters

pData	Stream data.
iDataLen	Length of pData.
bComplex	true if pData is a stream of "complex" chunks, false if pData is a stream of "simple" chunks. Passing the wrong value will usually result in a very visible wrong result.
