## Detailed Description

The struct represents integer rectangle for Windows coordinates. Defined as equivalent of Windows RECT structure, with some convenient function members. This structure use Windows space where Y axis runs from top to bottom.

## Member Function Documentation

## ◆ constructor()

RectI.constructor | ( | left1 | ,
|  | top1 | ,
|  | right1 | ,
|  | bottom1 |
| ) |  |

Construct a rect with left-top and right bottom corners.

Parameters

  [in] | left1 | The left.
  [in] | top1 | The top.
  [in] | right1 | The right.
  [in] | bottom1 | The bottom.

## ◆ Contains() [1/2]

RectI.Contains | ( | other_rect |  | ) |

Check if current rectangle fully contains the other provided rectangle. That means to check if the other rectangle is fully inside current one.

Parameters

  [in] | other_rect | The other provided rect.

Returns
  true means current rect fully contains the other rectangle, while false means not.

## ◆ Contains() [2/2]

RectI.Contains | ( | x | ,
|  | y |
| ) |  |

Check if current rectangle contains the provided point. That means to check if the provided point is inside current one.

Parameters

  [in] | x | The x coordinate of the provided point.
  [in] | y | The y coordinate of the provided point.

Returns
  true means current rect contains the provided point, while false means not.

## ◆ Height()

RectI.Intersect | ( | left1 | ,
|  | top1 | ,
|  | right1 | ,
|  | bottom1 |
| ) |  |

Intersect with a rect.

Parameters

  [in] | left1 | The left of the rect to intersect with.
  [in] | top1 | The top of the rect to intersect with.
  [in] | right1 | The right of the rect to intersect with.
  [in] | bottom1 | The bottom of the rect to intersect with.

Returns
