fengdragon / FastEditDistanceCandidates.cpp

Created April 25, 2016 07:11 — forked from markpapadakis/FastEditDistanceCandidates.cpp

From input string, identify all strings within a specific edit distance from it - based on deletions only.

	// Compile list of tokens based on deletions, and respecting max edit distance
	// Original implementation would concatenate left/right string segments using memcpy() etc, but that didn't seem right
	// The idea is, to instead partition S into 1+ segments and build hash from them, no need for memory copies etc.
	// This is almost x8 times faster compared to that - but it's still in the 10s of microseconds range.
	//
	// ( for a 31 characters long string, with max edit distance = 2, it takes 24 microseconds, including the cost for computing the FNV rolling hash )

Create an animated gif in swift

	func createGIF(with images: [UIImage], loopCount: Int = 0, frameDelay: Double, callback: (data: NSData?, error: NSError?) -> ()) {
	let fileProperties = [kCGImagePropertyGIFDictionary as String: [kCGImagePropertyGIFLoopCount as String: loopCount]]
	let frameProperties = [kCGImagePropertyGIFDictionary as String: [kCGImagePropertyGIFDelayTime as String: frameDelay]]

	let documentsDirectory = NSTemporaryDirectory()
	let url = NSURL(fileURLWithPath: documentsDirectory)?.URLByAppendingPathComponent("animated.gif")

	if let url = url {
	let destination = CGImageDestinationCreateWithURL(url, kUTTypeGIF, UInt(images.count), nil)
	CGImageDestinationSetProperties(destination, fileProperties)
