CGRect Methods

---

Overview

For manipulating CGRects.

These methods provide additional means of modifying the edges of CGRects beyond the basics included in CoreGraphics.

Functions
CGRect	NIRectContract (CGRect rect, CGFloat dx, CGFloat dy)
CGRect	NIRectShift (CGRect rect, CGFloat dx, CGFloat dy)

Function Documentation

CGRect NIRectContract	(	CGRect	rect,
		CGFloat	dx,
		CGFloat	dy
	)

Modifies only the right and bottom edges of a CGRect.

Returns:

a CGRect with dx and dy subtracted from the width and height.

Example result: CGRectMake(x, y, w - dx, h - dy)

CGRect NIRectShift	(	CGRect	rect,
		CGFloat	dx,
		CGFloat	dy
	)

Modifies only the top and left edges of a CGRect.

Returns:

a CGRect whose origin has been offset by dx, dy, and whose size has been contracted by dx, dy.

Example result: CGRectMake(x + dx, y + dy, w - dx, h - dy)
