rBackgroundColor	Background color to use for every pixel during alpha blending

Returns: true, if blending was successful, false otherwise

bool Bitmap::CopyPixel	(	const tools::Rectangle &	rRectDst,
		const tools::Rectangle &	rRectSrc,
		const Bitmap *	pBmpSrc = `nullptr`
	)

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.
pBmpSrc	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.

Bitmap Bitmap::CreateMask	(	const Color &	rTransColor,

	)		const

Create on-off mask from bitmap.

This method creates a bitmask from the bitmap, where every pixel that equals rTransColor is set transparent, the rest opaque.

Parameters

rTransColor	Color value where the bitmask should be transparent
nTol	Tolerance value. Specifies the maximal difference between rTransColor and the individual pixel values, such that the corresponding pixel is still regarded as transparent.

Returns: the resulting bitmask.

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

bool Bitmap::Dither ( )

Apply a Floyd dither algorithm to the bitmap.

bool Bitmap::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.
