Return: void

Action: sets the (1-bit) pixel to 0

l_clearDataDibit()

void l_clearDataDibit	(	void *	line,
		l_int32	n
	)

l_clearDataDibit()

Input:  line  (ptr to beginning of data line)
        n     (pixel index)

void l_clearDataQbit	(	void *	line,
		l_int32	n
	)

l_clearDataQbit()

Input:  line  (ptr to beginning of data line)
        n     (pixel index)

Action: sets the (4-bit) pixel to 0

l_getDataBit()

l_int32 l_getDataBit	(	void *	line,
		l_int32	n
	)

l_getDataBit()

Input:  line  (ptr to beginning of data line)
        n     (pixel index)
Return: val of the nth (1-bit) pixel.

l_getDataByte()

l_int32 l_getDataByte	(	void *	line,
		l_int32	n
	)

l_getDataByte()

Input:  line  (ptr to beginning of data line)
        n     (pixel index)
Return: value of the n-th (byte) pixel

l_getDataDibit()

l_int32 l_getDataDibit	(	void *	line,
		l_int32	n
	)

l_getDataDibit()

Input:  line  (ptr to beginning of data line)
        n     (pixel index)
Return: val of the nth (2-bit) pixel.

l_getDataFourBytes()

l_int32 l_getDataFourBytes	(	void *	line,
		l_int32	n
	)

l_getDataFourBytes()

Input:  line  (ptr to beginning of data line)
        n     (pixel index)
Return: value of the n-th (4-byte) pixel

l_getDataQbit()

l_int32 l_getDataQbit	(	void *	line,
		l_int32	n
	)

l_getDataQbit()

Input:  line  (ptr to beginning of data line)
        n     (pixel index)
Return: val of the nth (4-bit) pixel.

l_getDataTwoBytes()

l_int32 l_getDataTwoBytes	(	void *	line,
		l_int32	n
	)

l_getDataTwoBytes()

Input:  line  (ptr to beginning of data line)
        n     (pixel index)
Return: value of the n-th (2-byte) pixel

l_setDataBit()

void l_setDataBit	(	void *	line,
		l_int32	n
	)

l_setDataBit()

Input:  line  (ptr to beginning of data line)
        n     (pixel index)
Return: void

Action: sets the pixel to 1

l_setDataBitVal()

void l_setDataBitVal	(	void *	line,
		l_int32	n,
		l_int32	val
	)

l_setDataBitVal()

Input:  line  (ptr to beginning of data line)
        n     (pixel index)
        val   (val to be inserted: 0 or 1)
Return: void

Notes: (1) This is an accessor for a 1 bpp pix. (2) It is actually a little slower than using: if (val == 0) l_ClearDataBit(line, n); else l_SetDataBit(line, n);

l_setDataByte()

void l_setDataByte	(	void *	line,
		l_int32	n,
		l_int32	val
	)

l_setDataByte()

Input:  line  (ptr to beginning of data line)
        n     (pixel index)
        val   (val to be inserted: 0 - 0xff)
Return: void

l_setDataDibit()

void l_setDataDibit	(	void *	line,
		l_int32	n,
		l_int32	val
	)

l_setDataDibit()

Input:  line  (ptr to beginning of data line)
        n     (pixel index)
        val   (val to be inserted: 0 - 3)
Return: void

l_setDataFourBytes()

void l_setDataFourBytes	(	void *	line,
