gradient

问题 Is it possible to add gradient color to 2-D line in Matlab, especially when you have small number of data points (less than 10?), so the result would be similar to one in image below? 回答1: This is not difficult if you have MATLAB R2014b or newer. n = 100; x = linspace(-10,10,n); y = x.^2; p = plot(x,y,'r', 'LineWidth',5); % modified jet-colormap cd = [uint8(jet(n)*255) uint8(ones(n,1))].'; drawnow set(p.Edge, 'ColorBinding','interpolated', 'ColorData',cd) Which results in: Excerpted from

问题 I'm a beginner at SVG, but I'd like to learn some techniques. To be short, is there a simple way to create something like this? I was thinking about creating a polar gradient and then clipping it: But how do I generate a polar gradient? Even if there's no native method, maybe it could be made with a simple linear gradient and then using some rectangular-polar coordinate transformation. Is there a way to do so? 回答1: So this is the solution I developed: <?xml version="1.0" standalone="no"?> <

问题 I’m making a set of buttons which use dynamic gradients. I’ve taken care of Firefox 3.6+ and WebKit by using their proprietary CSS extensions and all I need to do is support Opera, iOS and IE9 by using background-image: url("gradient.svg"). This is relatively easy, I made an SVG file, linked it and got it working. However, I’m making a set so I need at least 6 gradients. When I normally do it in images, I create a sprite for fast HTTP access. I’m not sure how to achieve this in SVG – can I

问题 On emulators running Android 4.0 or 4.0.3, I am seeing horrible colour banding which I can't seem to get rid of. On every other Android version I have tested, gradients look smooth. I have a SurfaceView which is configured as RGBX_8888, and the banding is not present in the rendered canvas. If I manually dither the image by overlaying a noise pattern at the end of rendering I can make the gradients smooth again, though obviously at a cost to performance which I'd rather avoid. So the banding

问题 I know there is -webkit-gradient and -moz-linear-gradient . But what is the standard way of defining a gradient? Like there is: -webkit-border-radius and -moz-border-radius and the standard is meant to be border-radius . 回答1: An update for 2011, the Mozilla syntax is now the 'official' one, adopted by the CSS3 Image Values and Replaced Content Working Draft. Webkit has been updated to use this syntax too, and this has now been incorporated into the latest versions of Chrome and Safari. 回答2:

问题 I would like to draw a circular gradient like in the example picture below. I can manage a radial gradient easily but I am not sure how to do a circular one. I was thinking of drawing a gradient on a line and then transforming it to a circle. Would that be possible? This is how I draw the radial gradient: CGFloat a = MIN(self.frame.size.width, self.frame.size.height) - _lineWidth; //Get current context CGContextRef mainContext = UIGraphicsGetCurrentContext(); CGRect newRect = rect; newRect

问题 I would like to create effect like on this image - gradient opacity on the bottom of content: How can i do it? 回答1: You can use this HTML <div class="content"> Loriem ispsum is simply dummy text<br> Loriem ispsum is simply dummy text<br> Loriem ispsum is simply dummy text<br> Loriem ispsum is simply dummy text<br> Loriem ispsum is simply dummy text<br> Loriem ispsum is simply dummy text<br> Loriem ispsum is simply dummy text<br> Loriem ispsum is simply dummy text<br> Loriem ispsum is simply

问题 Need to add gradient effect for borders. borders are triangle shaped here is the jsfiddle code .progress-indicator-wrapper { margin: 0 10px; font-size: 16px; color: #2f2f2f; background-image: linear-gradient(to bottom, #e7e7e7, #d8d8d8); } .progress-indicator { display: table; width: 100%; text-align: center; line-height: 20px; } .progress-indicator > div { display: table-cell; margin-top: 0; padding: 20px; position: relative; } .progress-indicator > div.progress-active::before { content: " "

问题 I'm attempting to use a CSS gradient in a div containing some text. With Gecko and Webkit, the text displays fine. In IE7 & IE8 the text appears aliased (jaggy). I came across this blog stating: "we decided to disable ClearType on elements that use any DXTransform". IE Blog: http://blogs.msdn.com/ie/archive/2006/08/31/730887.aspx That was back in 2006; 3.5 years later, I assume this bug would be fixed, but it's not. Is there a way to do this in IE8 without resorting to stuffing a repeating
