gradient

I'm trying to build a background animation with jQuery which changes from one gradient to another. I know you can use the .animate() function to change solid background colors, but can this also be done for gradients? Here's a good example from some old Digg-style comments. I'm looking to do something like this animating from green to yellow UPDATE: These days, all major browsers support CSS animations, which are way more reliable than jQuery. For reference, see Rohit's answer. OLD ANSWER: Animating the backgrounds directly is nearly impossible with jQuery, at least I could think of no way.

I have a problem: I need to be able to take two colors and make a 'virtual gradient' out of them. I then need to be able to find the color at any point on this line. My current approach is this: if (fahrenheit < kBottomThreshold) { return [UIColor colorWithRed:kBottomR/255.0f green:kBottomG/255.0f blue:kBottomB/255.0f alpha:1]; } if (fahrenheit > kTopThreshold) { return [UIColor colorWithRed:kTopR/255.0f green:kTopG/255.0f blue:kTopB/255.0f alpha:1]; } double rDiff = kTopR - kBottomR; double gDiff = kTopG - kBottomG; double bDiff = kTopB - kBottomB; double tempDiff = kTopThreshold -

I'm using TensorFlow to build a deep learning model. And new to TensorFlow. Due to some reason, my model has limited batch size, then this limited batch-size will make the model has a high variance. So, I want to use some trick to make the batch size larger. My idea is to store the gradients of each mini-batch, for example 64 mini-batches, and then sum the gradients together, use the mean gradients of this 64 mini batches of training data to update the model's parameters. This means that for the first 63 mini-batches, do not update the parameters, and after the 64 mini batch, update the model

How to create multi-color linear gradient in WinForms? System.Drawing.Drawing2D.LinearGradientBrush allows only two colors. punker76 same answer as here: Multi-color diagonal gradient in winforms Multi-color diagonal gradient in winforms Here is a little example void MainFormPaint(object sender, PaintEventArgs e) { LinearGradientBrush br = new LinearGradientBrush(this.ClientRectangle, Color.Black, Color.Black, 0 , false); ColorBlend cb = new ColorBlend(); cb.Positions = new[] {0, 1/6f, 2/6f, 3/6f, 4/6f, 5/6f, 1}; cb.Colors = new[] {Color.Red, Color.Orange, Color.Yellow, Color.Green, Color.Blue

Dipping my feet into some more Core Graphics drawing, I'm attempting to recreate a wicked looking metallic knob, and I've landed on what is probably a show-stopping issue. There doesn't seem to be any way to draw angle gradients in Core Graphics. I see there's CGContextDrawRadialGradient() and CGContextDrawLinearGradient() , but there's nothing that I see that would allow me to draw an angle gradient. Does anyone know of a workaround, or a bit of framework hidden away somewhere to accomplish this without pre-rendering the knob into an image file? AngleGradientKnob http://dl.dropbox.com/u

How can I design programmatically UIButton like this gradient border color? ] Thanks for help let gradient = CAGradientLayer() gradient.frame = CGRect(origin: CGPointZero, size: self.myButton.frame.size) gradient.colors = [UIColor.blueColor().CGColor, UIColor.greenColor().CGColor] let shape = CAShapeLayer() shape.lineWidth = 2 shape.path = UIBezierPath(rect: self.myButton.bounds).CGPath shape.strokeColor = UIColor.blackColor().CGColor shape.fillColor = UIColor.clearColor().CGColor gradient.mask = shape self.myButton.layer.addSublayer(gradient) Swift 3 version: let gradient = CAGradientLayer()

i want to create a rainbow circle like the picture below: but how can i draw the curved and multiple color stop gradient? here's my current code: <svg width="500" height="500" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink"> <defs> <linearGradient id="test"> <stop offset="0%" stop-color="#f00"/> <stop offset="100%" stop-color="#0ff"/> </linearGradient> </defs> <circle cx="50" cy="50" r="40" fill="none" stroke="url(#test)" stroke-width="6"/> </svg> This approach won't work. SVG doesn't have conical gradients. To simulate the effect, you would have to fake it with a

The code for drawing an arrow with Style: Fill is given below: paint.setColor(Color.parseColor("#bdc0dc")); paint.setStyle(Style.FILL); canvas.drawPath(arrowPath, paint); paint.setColor(Color.BLACK); paint.setStyle(Style.STROKE); paint.setStrokeWidth(2); canvas.drawPath(arrowPath, paint); And the output I obtain is this : Now what I want do is set style to Gradient(Style.gradient not present in android...) to obtain the arrow similar to the image given below : How do i do it ? I tried adding style in style.xml but was unable to add gradient there as it accepts item as parameter.. use the code
