SDL_GetRectAndLineIntersectionFloat - Calculate the intersection of a rectangle and line segment with

Availability

       This function is available since SDL 3.2.0.

Simple Directmedia Layer                           SDL 3.2.10             SDL_GetRectAndLineIntersectionFloat(3)

Description

       This function is used to clip a line segment to a rectangle. A line segment contained entirely within the
       rectangle or that does not intersect will remain unchanged. A line segment that crosses the rectangle  at
       either  or both ends will be clipped to the boundary of the rectangle and the new coordinates saved in X1
       , Y1 , X2 , and/or Y2 as necessary.

Function Parameters

rect   an SDL_FRect
               structure representing the rectangle to intersect.

       X1     a pointer to the starting X-coordinate of the line.

       Y1     a pointer to the starting Y-coordinate of the line.

       X2     a pointer to the ending X-coordinate of the line.

       Y2     a pointer to the ending Y-coordinate of the line.

Header File

       Defined in SDL3/SDL_rect.h

Name
