Rect

The Rect struct defines a rectangle with properties for the left, right, bottom, and top coordinates, and provides various methods to manipulate and query the rectangle.

#include <interface/TellusimTypes.h>

Constructors​

Rect()
explicit Rect(float32_t value)
Rect(float32_t horizontal, float32_t vertical)
Rect(float32_t left, float32_t right, float32_t bottom, float32_t top)

Methods​

Check rectangle.

bool isValid() const
operator bool() const

Expand by point.

Rect &expand(float32_t x, float32_t y)

Expand by rectangle.

Rect &expand(const Rect &rect)

Shrink by rectangle.

Rect &shrink(const Rect &rect)

Inside point.

bool inside(float32_t x, float32_t y) const
bool inside(const Vector2f &v) const
