lanephillips / CGRectAspectFit.m

Created October 7, 2013 21:05

Objective-C code to fit a CGRect inside or outside another CGRect while maintaining aspect ratio. The fitted rectangle is centered on the target rectangle.

	CGFloat ScaleToAspectFitRectInRect(CGRect rfit, CGRect rtarget)
	{
	// first try to match width
	CGFloat s = CGRectGetWidth(rtarget) / CGRectGetWidth(rfit);
	// if we scale the height to make the widths equal, does it still fit?
	if (CGRectGetHeight(rfit) * s <= CGRectGetHeight(rtarget)) {
	return s;
	}
	// no, match height instead
	return CGRectGetHeight(rtarget) / CGRectGetHeight(rfit);
