radial-gradients

I have a custom CALayer that draws radial gradients. It works great except during animation. It seems that each iteration of CABasicAnimation creates a new copy of the CALayer subclass with empty, default values for the properties: In the screenshot above, you see that CABasicAnimation has created a new copy of the layer and is updating gradientOrigin but none of the other properties have come along for the ride. This has the result of not rendering anything during the animation. Here's a GIF: Here's what is should look like: Here's the animation code: let animation = CABasicAnimation(keyPath:

I have a Rectangle with rounded corners (but not an ellipse), something like this: <Rectangle Stroke="Black" StrokeThickness="2" RadiusX="50" RadiusY="100"> <Rectangle.Fill> <RadialGradientBrush RadiusY="0.5"> <GradientStop Color="Black" Offset="1" /> <GradientStop Color="White" Offset="0.8" /> </RadialGradientBrush> </Rectangle.Fill> </Rectangle> I want to use a gradient fill from black to white. How can I specify this in order to make the fill keep the shape of the rounded rectangle, instead of being an ellipse? For a rounded rectangle you can do it all in XAML using radial gradients for the

I want animate a background with a radial-gradient radial-gradient(circle, rgba(255,255,255,0.8) 0, rgba(255,255,255,0) 100%) , to move it from left to right http://jsfiddle.net/odsb1fjh/2/ how can I do to animate this radial-gradient to move infinite on div from left to right? I have already try animation and keyframe background-position: left/right bottom; but don't works. "but we can see the border of "square" where is the light radial" - Why use radial background at all, simply use: div div { position: absolute; width: 250px; height: 250px; background-color: black; background-image: url

I'm playing around with createRadialGradient() on HTML5 canvas. It works like a charm, except when I'm trying to implement (semi-)transparency. I made this jsFiddle to make things hopefully clearer: http://jsfiddle.net/rfLf6/1/ . function circle(x, y, r, c) { ctx.beginPath(); var rad = ctx.createRadialGradient(x, y, 1, x, y, r); rad.addColorStop(0, c); rad.addColorStop(1, 'transparent'); ctx.fillStyle = rad; ctx.arc(x, y, r, 0, Math.PI*2, false); ctx.fill(); } ctx.fillRect(0, 0, 256, 256); circle(128, 128, 200, 'red'); circle(64, 64, 30, 'green'); What is happening is a circle (radial gradient

Is there any way to create circle with gradient like this ? As far as i get is this: <shape android:innerRadiusRatio="3" android:thicknessRatio="10" android:shape="ring"> <gradient android:endColor="@color/cyan_dark" android:startColor="@color/red" android:type="radial" android:gradientRadius="340" android:centerX="50%" android:centerY="0" /> </shape> XML <ProgressBar android:id="@+id/yourId" style="?android:attr/progressBarStyleHorizontal" android:layout_width="89dp" android:layout_height="89dp" android:layout_centerHorizontal="true" android:layout_centerVertical="true" android:max="100"
