cashapelayer

I have a issue with masking images. I do game "puzzle" and have to make custom images. I found and tried 2 way of custom cropping: Using CALayer.mask property. Using UIImage.mask property. In first option i create my custom path, then assign it to CAShapeLayer.path property, then assign CAShapeLayer to CALayer.mask property. At the end i have custom cropped image. In second option i use firstly use CGImageMaskCreate() method (i use previously created black mask images of puzzle), then CGContextClipToMask() . In either options i have problem with performance (mostly when i crop image into 16

I am attempting to draw a stroked circle by using a CAShapeLayer and setting a circular path on it. However, this method is consistently less accurate when rendered to the screen than using borderRadius or drawing the path in a CGContextRef directly. Here are the results of all three methods: Notice that the third is poorly rendered, especially inside the stroke on the top and bottom. I have set the contentsScale property to [UIScreen mainScreen].scale . Here is my drawing code for these three circles. What’s missing to make the CAShapeLayer draw smoothly? @interface BCViewController () @end

I'm trying to animate a UIBezierPath and I've installed a CAShapeLayer to try to do it. Unfortunately the animation isn't working and I'm not sure any of the layers are having any affect (as the code is doing the same thing it was doing before I had the layers). Here is the actual code - would love any help. Draw2D is an implementation of UIView that is embedded in a UIViewController. All the drawing is happening inside the Draw2D class. The call to [_helper createDrawing... ] simply populates the _uipath variable with points. Draw2D.h defines the following properties: #define

I want to draw a circle with color gradient stroke like the following picture, on both iOS and macOS: Is it possible to implement with CAShapeLayer or NSBezierPath / CGPath ? Or any other ways? In macOS 10.14 and later (as well as in iOS 12 and later), you can create a CAGradientLayer with a type of .conic , and then mask it with a circular arc. For example, for macOS: class GradientArcView: NSView { var startColor: NSColor = .white { didSet { setNeedsDisplay(bounds) } } var endColor: NSColor = .blue { didSet { setNeedsDisplay(bounds) } } var lineWidth: CGFloat = 3 { didSet { setNeedsDisplay

I have designed this code to generate a Bezier Path that is used as a path for a CAShapeLayer to mask a UIView (the view's height and width are variable) This code generates a triangle with sharp edges, but I would like to make it round cornered! I have spent a good 2 hours trying to work with addArcWithCenter... , lineCapStyle and lineJoinStyle etc but nothing seems to work for me. UIBezierPath *bezierPath = [UIBezierPath bezierPath]; CGPoint center = CGPointMake(rect.size.width / 2, 0); CGPoint bottomLeft = CGPointMake(10, rect.size.height - 0); CGPoint bottomRight = CGPointMake(rect.size
