I'm trying to find the best approach to build a music visualizer to run in a browser over the web. Unity is an option, but I'll need to build a custom audio import/analysis plugin to get the end user's sound output. Quartz does what I need but only runs on Mac/Safari. WebGL seems not ready. Raphael is mainly 2D, and there's still the issue of getting the user's sound... any ideas? Has anyone done this before? Brian McKenna By WebGL being "not ready", I'm assuming that you're referring to the penetration (it's only supported in WebKit and Firefox at the moment). Other than that, equalisers are

I found this answer on how to draw rotated text with NSString drawInRect:, but I'm not sure how it works since it only sort of works for me: https://discussions.apple.com/thread/1779814?start=0&tstart=0 My code looks like: CGContextSaveGState(context); CGContextDrawLinearGradient(context, gradient, CGPointMake(0, centY - halfWidth), CGPointMake(0, centY + halfWidth), 0); // Add text CGContextSetFillColorWithColor(context, [UIColor whiteColor].CGColor); NSString *str = @"some test string"; CGAffineTransform transform1 = CGAffineTransformMakeRotation(M_PI/4); CGContextConcatCTM(context,

I would like to create a 1x1 UIImage dynamically based on a UIColor. I suspect this can quickly be done with Quartz2d, and I'm poring over the documentation trying to get a grasp of the fundamentals. However, it looks like there are a lot of potential pitfalls: not identifying the numbers of bits and bytes per things correctly, not specifying the right flags, not releasing unused data, etc. How can this be safely done with Quartz 2d (or another simpler way)? Matt Stevens You can use CGContextSetFillColorWithColor and CGContextFillRect for this: Swift extension UIImage { class func image(with
