◆ getB2DRange()

B2DRange const & basegfx::B2DPolygon::getB2DRange ( ) const

Get the B2DRange (Rectangle dimensions) of this B2DPolygon.

A polygon may have up to three ranges:

(a) the range of the polygon points (b) the range of the polygon points and control points (c) the outer range of the subdivided bezier curve

Ranges (a) and (c) are produced by tools::getRange(); resp. this getB2DRange(). tools::getRangeWithControlPoints handles case (b).

To get range (c) a simple solution would be to subdivide the polygon and use getRange() on it. Since subdivision is expensive and decreases the polygon quality, i added this new method. It will use a methodology suggested by HDU. First, it gets the range (a). Then it iterates over the bezier segments and for each it first tests if the outer range of the bezier segment is already contained in the result range.

The subdivision itself uses getAllExtremumPositions() to only calculate extremum points and to expand the result accordingly. Thus it calculates maximal four extremum points on the bezier segment, no split is used at all.

Returns: The outer range of the bezier curve/polygon

◆ getBezierSegment()

void basegfx::B2DPolygon::getBezierSegment	(	sal_uInt32	nIndex,

bezier segment access

This method also works when it is no bezier segment at all and will fill the given B2DCubicBezier as needed. In any case, the given B2DCubicBezier will be filled, if necessary with the single start point (if no valid edge exists).

Parameters

nIndex	Index of the addressed edge's start point
rTarget	The B2DCubicBezier to be filled. It's data WILL be changed.

◆ getDefaultAdaptiveSubdivision()

B2DPolygon const & basegfx::B2DPolygon::getDefaultAdaptiveSubdivision ( ) const

Default adaptive subdivision access.

This method will return a default adaptive subdivision of the polygon. If the polygon does not contain any bezier curve segments, it will just return itself.

The subdivision is created on first request and buffered, so when using this subdivision You have the guarantee for fast accesses for multiple usages. It is intended for tooling usage for tasks which would be hard to accomplish on bezier segments (e.g. isInEpsilonRange).

The current default subdivision uses adaptiveSubdivideByCount with 9 subdivisions which gives 10 edges and 11 points per segment and is usually pretty usable for processing purposes. There is no parameter passing here ATM but it may be changed on demand. If needed, a TYPE and PARAMETER (both defaulted) may be added to allow for switching between the different kinds of subdivisioned and passing them one parameter.

The lifetime of the buffered subdivision is based on polygon changes. When changing the polygon, it will be flushed. It is buffered at the refcounted implementation class, so it will survive copy by value and combinations in PolyPolygons.

Returns: The default (and buffered) subdivision of this polygon. It may be this polygon itself when it has no bezier segments. It is guaranteed to have no more bezier segments
