okay bestie, welcome to QwtClipper(3), straight outta the Qwt User's Guide 🌸. no cap, this one's a lil utility class that's just... here to clip things for you. no constructors, no drama, just vibes and math. ✨

🌈 NAME 🌈

QwtClipper — that's it, that's the name, she's mysterious like that 💅

✨ SYNOPSIS ✨

first things first, you gotta let the compiler know she exists:

#include <qwt_clipper.h>

🎀 Static Public Member Functions 🎀

these are the girlies. all static, all serving:

static QwtArray< QwtDoubleInterval > clipCircle(const QwtDoubleRect &, const QwtDoublePoint &, double radius)
static QwtPolygon clipPolygon(const QRect &, const QwtPolygon &)
static QwtPolygonF clipPolygonF(const QwtDoubleRect &, const QwtPolygonF &)

🦋 Detailed Description 🦋

literally just: Some clipping algos. 🫶 that's the whole description. she's concise. she knows what she is.

👑 Member Function Documentation 👑

💜 QwtArray< QwtDoubleInterval > QwtClipper::clipCircle(const QwtDoubleRect &clipRect, const QwtDoublePoint &center, doubleradius) [static]

circle clipping, bestie 🍓

so clipCircle() devides a circle into intervals of angles representing arcs of the circle. and listen — when the circle is completely inside the clip rectangle, you get an interval [0.0, 2 * M_PI] back. full circle, full slay, periodt. 💫

Parameters:

  • clipRect — Clip rectangle
  • center — Center of the circle
  • radius — Radius of the circle

Returns:

  • Arcs of the circle

🌸 QwtPolygon QwtClipper::clipPolygon(const QRect &clipRect, const QwtPolygon &polygon) [static]

Sutherland-Hodgman polygon clipping ✂️ iconic algorithm behavior, ngl.

Parameters:

  • clipRect — Clip rectangle
  • polygon — Polygon

Returns:

  • Clipped polygon

⭐ QwtPolygonF QwtClipper::clipPolygonF(const QwtDoubleRect &clipRect, const QwtPolygonF &polygon) [static]

Sutherland-Hodgman polygon clipping again but make it float 🌈 (that's the F, iykyk).

Parameters:

  • clipRect — Clip rectangle
  • polygon — Polygon

Returns:

  • Clipped polygon
