		const ::basegfx::B2DRange &	i_srcRect,
		const ::basegfx::B2DHomMatrix &	i_transformation
	)

Calc a transform that maps the upper, left corner of a rectangle to the origin.

The method is a specialized version of calcRectToRectTransform() (Removed now), mapping the input rectangle's the upper, left corner to the origin, and leaving the size untouched.

Parameters

o_transform	Output parameter, to receive the resulting transformation matrix.
i_srcRect	Input parameter, specifies the original source rectangle. The resulting transformation will exactly map the source rectangle's upper, left corner to the origin.
i_transformation	The original transformation matrix. This is changed with translations (if necessary), to exactly map the source rectangle to the origin.

Returns

a reference to the resulting transformation matrix

	)

Calc the bounding rectangle of a transformed rectangle.

The method applies the given transformation to the specified input rectangle, and returns the bounding box of the resulting output area.

Parameters

i_Rect	Input rectangle
i_Transformation	Transformation to apply to the input rectangle

Returns

a reference to the resulting rectangle

		::std::vector< ::basegfx::B2IRange > &	o_ClippedAreas,
		const ::basegfx::B2IRange &	rBounds
	)

Clip a scroll to the given bound rect.

Parameters

io_rSourceArea	Source area to scroll. The resulting clipped source area is returned therein.
io_rDestPoint	Destination point of the scroll (upper, left corner of rSourceArea after the scroll). The new, resulting destination point is returned therein.q
o_ClippedAreas	Vector of rectangles in the destination area coordinate system, which are clipped away from the source area, and thus need extra updates (i.e. they are not correctly copy from the scroll operation, since there was no information about them in the source).
rBounds	Bounds to clip against.

Returns

false, if the resulting scroll area is empty

Retrieve various internal properties of the actual canvas implementation.

This method retrieves a bunch of internal, implementation- and platform-dependent values from the canvas implementation. Among them are for example operating system window handles. The actual layout and content of the returned sequence is dependent on the component implementation, undocumented and subject to change.

Parameters

i_rxCanvas	Input parameter, the canvas representation for which the device information is to be retrieved
o_rxParams	Output parameter, the sequence of Anys that hold the device parameters. Layout is as described above

Returns

A reference to the resulting sequence of parameters

	)

Check whether a given rectangle is within another transformed rectangle.

This method checks for polygonal containedness, i.e. the transformed rectangle is not represented as an axis-aligned rectangle anymore (like calcTransformedRectBounds()), but polygonal. Thus, the insideness test is based on tight bounds.

Parameters

rContainedRect	This rectangle is checked, whether it is fully within the transformed rTransformRect.
rTransformRect	This rectangle is transformed, and then checked whether it fully contains rContainedRect.
rTransformation	This transformation is applied to rTransformRect

io_rDestPoint	Dest area of the blit. Returned therein is the computed clipped dest area.
rSourceBounds	Clip bounds of the source surface
rDestBounds	Clip bounds of the dest surface

Returns

false, if the resulting blit is empty, i.e. fully clipped away.

void canvas::tools::verifyInput	(	const T &	,
		const char *	,
		const css::uno::Reference< css::uno::XInterface > &	,

verifyRange() [1/2]

template<typename NumType >

void canvas::tools::verifyRange ( NumType  arg, NumType  bound, bool  bLowerBound = true  )

inline

Range checker, which throws css::lang::IllegalArgument exception, when range is violated.

The checked range is half open, i.e. only bound by the specified value.

Parameters

arg	Arg to check
bound	Bound to check against
bLowerBound	When true, given bound is the lower bound. When false, given bound is the upper bound.
