		short	nChannelGPercent,
		short	nChannelBPercent,
		double	fGamma = `1.0`,
		bool	bInvert = `false`,
		bool	msoBrightness = `false`
	)

Change various global color characteristics.

Parameters

nLuminancePercent	Percent of luminance change, valid range [-100,100]. Values outside this range are clipped to the valid range.
nContrastPercent	Percent of contrast change, valid range [-100,100]. Values outside this range are clipped to the valid range.
nChannelRPercent	Percent of red channel change, valid range [-100,100]. Values outside this range are clipped to the valid range.
nChannelGPercent	Percent of green channel change, valid range [-100,100]. Values outside this range are clipped to the valid range.
nChannelBPercent	Percent of blue channel change, valid range [-100,100]. Values outside this range are clipped to the valid range.
fGamma	Exponent of the gamma function applied to the bitmap. The value 1.0 results in no change, the valid range is (0.0,10.0]. Values outside this range are regarded as 1.0.
bInvert	If true, invert the channel values with the logical 'not' operator
msoBrightness	Use the same formula for brightness as used by MSOffice.

Returns: true, if the operation was completed successfully.

bool BitmapEx::Convert ( BmpConversion eConversion )

bool BitmapEx::CopyPixel	(	const tools::Rectangle &	rRectDst,
		const tools::Rectangle &	rRectSrc,
		const BitmapEx *	pBmpExSrc
	)

Copy a rectangular area from another bitmap.

Parameters

rRectDst	Destination rectangle in this bitmap. This is clipped to the bitmap dimensions.
rRectSrc	Source rectangle in pBmpSrc. This is clipped to the source bitmap dimensions. Note further that no scaling takes place during this copy operation, i.e. only the minimum of source and destination rectangle's width and height are used.
pBmpExSrc	The source bitmap to copy from. If this argument is NULL, or equal to the object this method is called on, copying takes place within the same bitmap.

Returns: true, if the operation completed successfully. false is not only returned when the operation failed, but also if nothing had to be done, e.g. because one of the rectangles are empty.

bool BitmapEx::Crop ( const tools::Rectangle & rRectPixel )

Crop the bitmap.

Parameters

rRectPixel A rectangle specifying the crop amounts on all four sides of the bitmap. If the upper left corner of the bitmap is assigned (0,0), then this method cuts out the given rectangle from the bitmap. Note that the rectangle is clipped to the bitmap's dimension, i.e. negative left,top rectangle coordinates or exceeding width or height is ignored.

Returns: true, if cropping was performed successfully. If nothing had to be cropped, because e.g. the crop rectangle included the bitmap, false is returned, too!

void BitmapEx::Replace	(	const Color &	rSearchColor,
		const Color &	rReplaceColor,
		sal_uInt8	nTolerance
	)

Replace all pixel having the search color with the specified color.

Parameters

rSearchColor	Color specifying which pixel should be replaced
rReplaceColor	Color to be placed in all changed pixel
nTolerance	Tolerance value. Specifies the maximal difference between rSearchColor and the individual pixel values, such that the corresponding pixel is still regarded a match.

void BitmapEx::Replace	(	const Color *	pSearchColors,
		const Color *	pReplaceColors,
		sal_uLong	nColorCount
	)

Replace all pixel having one the search colors with the corresponding replace color.

Parameters

pSearchColors	Array of colors specifying which pixel should be replaced
pReplaceColors	Array of colors to be placed in all changed pixel
nColorCount	Size of the aforementioned color arrays
pTols	Tolerance value. Specifies the maximal difference between pSearchColor colors and the individual pixel values, such that the corresponding pixel is still regarded a match.

void BitmapEx::Replace	(	const Color *	pSearchColors,
		const Color *	pReplaceColors,
		sal_uLong	nColorCount,
		sal_uInt8 const *	pTols
	)

Replace all pixel having one the search colors with the corresponding replace color.

Parameters

pSearchColors	Array of colors specifying which pixel should be replaced
rReplaceColors	Array of colors to be placed in all changed pixel
nColorCount	Size of the aforementioned color arrays
pTols	Tolerance value. Specifies the maximal difference between pSearchColor colors and the individual pixel values, such that the corresponding pixel is still regarded a match.

bool BitmapEx::Rotate	(	long	nAngle10,
		const Color &	rFillColor
	)

Rotate bitmap by the specified angle.

Parameters

nAngle10	The rotation angle in tenth of a degree. The bitmap is always rotated around its center.
rFillColor	The color to use for filling blank areas. During rotation, the bitmap is enlarged such that the whole rotation result fits in. The empty spaces around that rotated original bitmap are then filled with this color.

Returns: true, if the operation was completed successfully.
