I have a simple view for finger painting / drawing. I store the drawings as UIBezierPath s in a NSMutableArray . Now I want to transfer the drawings to a web-service for presenting them in a browser. Therefore I need to encode my UIBezierPath s in a SVG-file - because this the format of the web-service. What I found right now is the SVGKit , which only DECODES SVG. Do anybody know sample code, snippets or a framework for encoding SVG? Thank you. bitmapdata.com I tested yet. but using following steps: Would not it be possible? 1.UIBezierPath to CGPathRef. UIBezierPath to CGPathRef 2.Using a

I really dig the IFTTT bottom right corner button, as shown in the image (bottom right). I tried playing around with CGContext and UIBezierPath to match the effect, but i simply don't know enough to get this right. Does anyone have some thoughts/code on how to make this happen? Thanks! First use a CAShapeLayer to create a mask CAShapeLayer * shapeLayer = [CAShapeLayer layer]; //Use these to create path CGMutablePathRef path = CGPathCreateMutable(); // CGPathMoveToPoint // CGPathAddLines shapeLayer.path = path; Then set mask of your button yourbutton.layer.mask = shapeLayer yourbutton

I'm creating an application for iOS 5 and I'm drawing some gradients. The following gradient code I've always used before ARC, but now it does not work on my device anymore (however, it works on the simulator) when I use it several times (so I suppose it's a memory management issue). Anyways, here's the code: CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGFloat locations[] = { 0.0, 1.0 }; NSArray *colors = [NSArray arrayWithObjects:(__bridge id)startColor, (__bridge id)endColor, nil]; CGGradientRef gradient = CGGradientCreateWithColors(colorSpace, (__bridge CFArrayRef) colors,

I have a massive UIImage downloaded from a web resource (>300MBs) which when I attempt to render is causing an app crash due to memory. I am trying to resize the image using the following code: + (UIImage *)imageWithImage:(UIImage *)image scaled:(float) scale { //UIGraphicsBeginImageContext(newSize); CGSize size = (CGSize){scale * image.size.width, scale * image.size.height}; UIGraphicsBeginImageContextWithOptions(size, NO, 0.0); [image drawInRect:CGRectMake(0, 0, size.width, size.height)]; UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); return
