CGContextClosePath
CGContextClosePath is a function in the Core Graphics framework of Apple's iOS and macOS development environments, used primarily for vector-based drawing operations. It is part of the Quartz 2D graphics system, which provides a powerful API for rendering graphics programmatically. The function is designed to close the current path by drawing a straight line from the current point back to the initial point of the path, effectively sealing it.
When a path is created using functions like CGContextMoveToPoint or CGContextAddLineToPoint, it remains open until explicitly
CGContextClosePath is particularly useful in conjunction with other path-related functions such as CGContextFillPath, CGContextStrokePath, or CGContextFillStrokePath.
This function is commonly used in custom drawing methods, such as drawRect in UIKit or draw in
