◆ calculateDiscreteVisibleRange()

void drawinglayer::processor2d::calculateDiscreteVisibleRange	(	basegfx::B2DRange &	rDiscreteVisibleRange,
		const basegfx::B2DRange &	rContentRange,
		const drawinglayer::geometry::ViewInformation2D &	rViewInformation2D
	)

helper to calculate a discrete visible range based on a given logic range and a current ViewInformation2D.

This is used for pixel renderers. It is handy to check for visibility of a primitive, but also to continue working with just the visible discrete part.

The result rDiscreteVisibleRange will be reset if rContentRange is empty. Else it will be calculated. If ViewInformation2D does have a valid Viewport (getDiscreteViewport is not empty), it will also be clipped against that to calculate the visible part.

@param rDiscreteVisibleRange
The logic range in view-coordinates (will be transformed by
getObjectToViewTransformation)

@param rContentRange
The logic input range in view-coordinates (will be transformed by
getObjectToViewTransformation)

@param rViewInformation2D
The ViewInformation to work with (from the processor)

create the best available pixel based BaseProcessor2D (which may be system-dependent)

Parameters

rTargetOutDev	The target OutputDevice
rViewInformation2D	The ViewInformation to use

Returns: the created BaseProcessor2D (ownership change)

		const drawinglayer::geometry::ViewInformation2D &	rViewInformation2D
	)

create a BaseProcessor2D dependent on some states of the given OutputDevice.

If metafile is recorded, the needed VclMetafileProcessor2D will be created. If a pixel renderer is requested, the best one is incarnated

Parameters

rTargetOutDev	The target OutputDevice
rViewInformation2D	The ViewInformation to use

Returns: the created BaseProcessor2D (ownership change)

		BitmapEx &	rTarget,
		basegfx::B2DRange &	rFillUnitRange,
		double	fBigDiscreteArea = `300.0 *300.0`
	)

helper to process FillGraphicPrimitive2D:

In places that want to implement direct rendering of this primitive
e.g. in SDPRs all impls would need to handle the FillGraphicAttribute
settings and the type of Graphic. Unify this by this helper in one place
since this may get complicated (many cases to cover).
It will create and return a BitmapEx when direct tiled rendering is
preferable and suggested.
Of course every impl may still do what it wants, this is just to make
implementations easier.

@param rFillGraphicPrimitive2D
The primitive to work on

@param rViewInformation2D
The ViewInformation to work with (from the processor)

@param rTarget
The prepared PixelData to use for tiled rendering. If this
is empty on return this means to evtl. use the decompose.
Please hand in an empty one to make this work.

@param rFillUnitRange
This is a modifiable copy of FillGraphicAttribute.getGraphicRange(). We
need a modifiable one since params since OffsetX/OffsetY in
FillGraphicAttribute may require to change/adapt this if used

@param fBigDiscreteArea
Defines starting with which number of square pixels a target is seen
to be painted 'big'

@return
false: rendering is not needed (invalid, outside, ...), done
true: rendering is needed
   -> if rTarget is filled, use for tiled rendering
   -> if not, use fallback (primitive decomposition)

For the various reasons/things that get checked/tested/done, please
see the implementation

		BitmapEx &	rTarget,
		basegfx::B2DRange &	rFillUnitRange
	)

helper to react/process if OffsetX/OffsetY of the FillGraphicAttribute is used.

This is old but hard to remove stuff that allows hor/ver offset when
tiled fill is used. To solve that, create pixel data that doubles
resp. in width/height and copies the off-setted version of the bitmap
information to the extra space, so rendering does not need to do that.

Since this doubles the geometry, an adaption of the used fill range
(here rFillUnitRange in unit coordinates) also needs to be adapted,
refer to usage.
