Blocky gradient effect in CSS3

由 邮差的信 提交于 2019-11-26 12:32:32
问题 Is it possible to make the below gradient look more \"blocky\", so that instead of switching from green to red gradually, it\'s done in steps like the below picture? Desired effect: Currently: #gradients { background-image: -webkit-gradient(linear, left bottom, right bottom, color-stop(0, #00FF00), color-stop(0.5, #FFFF00), color-stop(1, #FF0000)); background-image: -o-linear-gradient(right, #00FF00 0%, #FFFF00 50%, #FF0000 100%); background-image: -moz-linear-gradient(right, #00FF00 0%,

问题 I\'m experimenting with Drawable backgrounds and have had no problems so far. I\'m now trying to change the gradient background color at runtime. Unfortunately, there\'s no API to change it at runtime, it seems. Not even by trying to mutate() the drawable, as explained here: Drawable mutations The sample XML looks like this. It works, as expected. <shape xmlns:android=\"http://schemas.android.com/apk/res/android\" android:shape=\"rectangle\"> <gradient android:startColor=\"#330000FF\" android

Here\'s a screenshot of what I want: So every 20 meters, I adding an overlay from the old to the new coordinates using: // Create a c array of points. MKMapPoint *pointsArray = malloc(sizeof

Colour points in a plot differently depending on a vector of values

由 我的梦境 提交于 2019-11-26 09:16:19
问题 I\'m plotting the plot below using R\'s plot function. It is a plot of a vector \'shiftTime\' of shift in time. I have another vector \'intensity\' of the intensity values ranging from ~3 to ~9. I want to color my points in the plot based on those values with a color gradient. The examples I can find color on the value of the actual plotted points, so in this case the values of the vector \'shiftTime\'. Is it also possible to use a different vector, as long as the corresponding values are on

Multi-gradient shapes

由 拥有回忆 提交于 2019-11-26 09:15:32
I'd like to create a shape that's like the following image: Notice the top half gradients from color 1 to color 2, but theres a bottom half that gradients from color 3 to color 4. I know how to make a shape with a single gradient, but I'm not sure how to split a shape into two halves and make 1 shape with 2 different gradients. Any ideas? kcoppock I don't think you can do this in XML (at least not in Android), but I've found a good solution posted here that looks like it'd be a great help!
