gradient

How to create gradient colour look like following image programatically. When you say "apply it over the image as a gradient", do you mean as a mask (revealing the image at the top, having it fade the image to transparent at the bottom)? If that's the case, you can apply that gradient as a mask, using CAGradientLayer : CAGradientLayer *gradientMask = [CAGradientLayer layer]; gradientMask.frame = self.imageView.bounds; gradientMask.colors = @[(id)[UIColor whiteColor].CGColor, (id)[UIColor clearColor].CGColor]; self.imageView.layer.mask = gradientMask; The above does a simple vertical gradient

Here is jsfiddle of a Sankey diagram : I am trying to modify colors of the links so that the color of each link is actually gradient from its source node color to its target node color. (it is assumed that opacity will remain 0.2 or 0.5 depending whether a mouse hovers or not over the link; so links will remain a little "paler" than nodes) I took a look at this nice and instructive example , which draws this gradient filled loop: However, I simply couldn't integrate that solution to mine, it looks too complex for the given task. Also, note that links in original Sankey diagram move while node

I'm using the internet explorer gradient filter in my CSS. It was all going well until I noticed that images that are supposed to extend beyond their containers overflow:visible; are getting clipped as though the container was set to overflow:hidden; I have no idea why this would happen, or how to fix it. Can anyone help? I'm looking at it in IE8 and IE7 This is the css causing the issue, when I comment it out, no more bug: .box{ filter: progid:DXImageTransform.Microsoft.gradient(GradientType=0,startColorstr='#b4cfe9', endColorstr='#e4eefc'); /* IE6 & IE7 */ -ms-filter: "progid

Today I was designing a transparent PNG background that would only sit in the top left of a div, and the rest of the div would maintain a gradient background for all transparent areas of the PNG, and the rest of the div itself. It might be better to explain through the code I thought might work: #mydiv .isawesome { /* Basic color for old browsers, and a small image that sits in the top left corner of the div */ background: #B1B8BD url('../images/sidebar_angle.png') 0 0 no-repeat; /* The gradient I would like to have applied to the whole div, behind the PNG mentioned above */ background: -moz

So this is essentially the method I would like to write (in Objective-C/Cocoa, using UIColors , but I'm really just interested in the underlying math): + (UIColor *)colorBetweenColor:(UIColor *)startColor andColor:(UIColor *)endColor atLocation:(CGFloat)location; So as an example, say I have two colors, pure red and pure blue. Given a linear gradient between the two, I want to calculate the color that's at, say, the 33% mark on that gradient: So if I were to call my method like so: UIColor *resultingColor = [UIColor colorBetweenColor:[UIColor redColor] andColor:[UIColor blueColor] atLocation:0

I'm trying to get a gradient applied to an SVG rect element. Currently, I'm using the fill attribute. In my CSS file: rect { cursor: pointer; shape-rendering: crispEdges; fill: #a71a2e; } And the rect element has the correct fill color when viewed in the browser. However, I'd like to know if I can apply a linear gradient to this element? Thomas W Just use in the CSS whatever you would use in a fill attribute. Of course, this requires that you have defined the linear gradient somewhere in your SVG. Here is a complete example: rect { cursor: pointer; shape-rendering: crispEdges; fill: url(

Several answers mention to use GradientDrawable.setDither(true) to draw smooth gradients in Android. That has no effect in my code. Any idea what I have to change to get a well looking gradient in my live wallpaper? GradientDrawable gradient = new GradientDrawable(Orientation.TL_BR, colors); gradient.setGradientType(GradientDrawable.RADIAL_GRADIENT); gradient.setGradientRadius(canvas.getWidth() * 2); gradient.setDither(true); gradient.setGradientCenter(-0.1f, -0.1f); gradient.setBounds(cb); gradient.draw(canvas); Eric Schlenz Seeing as you have a Canvas to work with. Here is one option.

I am going through test example. Where for some Image background they are using gradient, the code goes like this <?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android"> <gradient android:startColor="#ff0000" android:centerColor="#00ff00" android:endColor="#0000ff" android:angle="180"/> <corners android:radius="5dp" /> </shape> In the above xml I didn't get angle attribute. but when I change the value of angle slightly the pattern slants. Can anyone explain me how exactly it works? karn Gradient basically represents the variation in space(in a
