	)

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.

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.

Convert()

Parameters

eConversion

CopyPixel()

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.

Crop()

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!

Parameters

rTransformation	The transformation from unit coordinates to the unit range
rVisibleRange	The relative visible range in unit coordinates, relative to (0,0,1,1) which defines the whole target area
