Detailed Description

Current State Info for converting pixels from one SURF_FORM_TYPE to another. also re-sample/rescale the image if needed. for cSurfaceInfo like D3DXLoadSurfaceFromSurface()

Constructor & Destructor Documentation

◆ cSurfaceConv()

GrayLib::cSurfaceConv::cSurfaceConv	(	SURF_FORM_TYPE	eFormatSrc = `SURF_FORM_UNKNOWN`,
		SURF_FORM_TYPE	eFormatDst = `SURF_FORM_UNKNOWN`
	)

◆ ~cSurfaceConv()

GrayLib::cSurfaceConv::~cSurfaceConv ( )

Member Function Documentation

◆ ConvertLines()

void GrayLib::cSurfaceConv::ConvertLines	(	const void *	pvSrc,
		size_t	nSrcPitchBytes,
		void *	pvDst,
		size_t	nDstPitchBytes,
		int	nDstWidth,
		int	iDstHeight,
		bool	bTopDownFlip
	)

convert all the lines in an image.

◆ InitForm()

HRESULT GrayLib::cSurfaceConv::InitForm	(	SURF_FORM_TYPE	eFormatSrc,
		SURF_FORM_TYPE	eFormatDst = `SURF_FORM_UNKNOWN`
	)

define what formats we are converting from,to.

◆ isInitForm()

bool GrayLib::cSurfaceConv::isInitForm ( ) const

inlinenoexcept

did InitForm() work ?

◆ isScaling()

bool GrayLib::cSurfaceConv::isScaling ( ) const

inlinenoexcept

am i doing any scaling ? else just format convert or just copy.

◆ SetAlphaKey()

void GrayLib::cSurfaceConv::SetAlphaKey	(	COLOR_ELEM_t	r,
		COLOR_ELEM_t	g,
		COLOR_ELEM_t	b
	)

Set the color key for conversion to alpha supporting dest formats.

◆ SetScale()

bool GrayLib::cSurfaceConv::SetScale	(	PIXELS_t	nSrcWidth,
		PIXELS_t	nSrcHeight,
		PIXELS_t	nDstWidth,
		PIXELS_t	nDstHeight
	)

Returns: false = no scale needed. ASSUME isInitForm()

◆ UNITTEST_FRIEND()

GrayLib::cSurfaceConv::UNITTEST_FRIEND ( cSurfaceConv )

Member Data Documentation

◆ k_MaxLineWidth

const int GrayLib::cSurfaceConv::k_MaxLineWidth = 4096

static

max width in pixels for a single line.
