SL_Bresenham()

static void SL_Bresenham ( int  x0, int  y0, int  x1, int  y1, int  width, int  height, bool  rotated, unsigned char *  outputBuffer  )

SL_BSPSlice()

void SL_BSPSlice	(	const TR_TILE_TYPE *	model,
		float	thickness,
		int	scale,
		bool	singleFile,
		bool	multipleContour
	)

Parameters

[in]	model	The tile-info about the bsp-file we want to slice
[in]	thickness	the thickness of the brushes to render to the 2d map
[in]	scale	The scale of the png as passed via -s param. eg. 4 means: 1/4 or 1 pixels = 4 mapunits
[in]	singleFile	Put everything in one file. If false, create one file per level. As given by the -c param or the config default
[in]	multipleContour	Also draw all contours below the current slice. As given by the -m param or the config default

Todo:

remove these values once the mins/maxs calculation works
