TuiRect.Intersect

Returns the overlap of two rectangles, or an empty one if they do not touch.

Syntax

TuiRect.Intersect( byval o as TuiRect ) as TuiRect

Description

The overlap of two rects, or an empty rect when they do not touch. This is what clipping is built out of.

#import "std/tui"
using tui

dim as TuiRect a = TuiRectOf( 0, 0, 20, 10 )
dim as TuiRect b = TuiRectOf( 15, 5, 20, 10 )
dim as TuiRect hit = a.Intersect( b )
print hit.x, hit.y, hit.w, hit.h        '' 15 5 5 5

dim as TuiRect miss = a.Intersect( TuiRectOf( 50, 50, 4, 4 ) )
print miss.IsEmpty( )                   '' true -- ALWAYS check
