Detailed Description

A point or control-point on contour of bezier curves. The bezier curves can be linear (a line), quadratic or cubic.

Member Function Documentation

normalizePoints()

static std::vector< BezierPoint > tt::BezierPoint::normalizePoints ( std::vector< BezierPoint >::const_iterator const begin, std::vector< BezierPoint >::const_iterator const end )

inlinestaticnoexcept

Normalize points in a list. The following normalizations are executed:

• Missing anchor points between two quadratic-control-points are added.
• Missing first-cubic-control-points are added by reflecting the previous second-control point around the previous anchor.
• The list of points will start with an anchor.
• The list will close with the first anchor.

Parameters

begin	iterator to the start of the bezier point list.
end	iterator beyond the end of the bezier point list.

Returns

a vector of bezier point that include all the anchor and control points.

operator*=()

template<typename M , std::enable_if_t< is_mat_v< M >, int > = 0>
