gradient

问题 I have 2 line plots on the same figure, plotted from pandas dataframes. I want to fill between them with a gradient/colour map of sorts. I understand I can do this with a cmap, only it will not work for me (see code below). General example I found are filling between x axis and line, i do not want that and also i am interested in simplest solution possible for this as i am a begginer at this and complicated, though maybe better code will just make it more confusing honestly. Code for which

问题 I am learning WebGL and I've drawn a full screen quad with colors for each vertex. No lighting or normals or perspective matrix or depth buffer; I'm just drawing a gradient background. This is what I get: It looks good but I cannot help noticing the diagonal smear from the bottom right to the top left. I feel this is an artifact of linear interpolating the far opposite vertices. I'm drawing two triangles: the bottom left, and the top right. I think I would get similar results using OpenGL

问题 I was wondering if it is possible to create a gradient over text Flutter. There is a gist of text gradient using Dart's ui, but it is kinda long and I was hoping to be simpler. 回答1: Taken from here, you can use Text's style painter. Create the shader, final Shader linearGradient = LinearGradient( colors: <Color>[Color(0xffDA44bb), Color(0xff8921aa)], ).createShader(Rect.fromLTWH(0.0, 0.0, 200.0, 70.0)); then use it in the TextStyle's foreground Text( 'Hello Gradients!', style: new TextStyle(

问题 I am trying to recreate a button like this in Swift: I have been able to create the gradient inside of the button accurately from Sketch using the help from here: Answered Question Now I am trying to recreate the glow effect behind the button. I was thinking creating a subview behind it and using a gaussian blur filter to draw it. Now I am stuck in how to implement this, and haven't found a good solution. The normal CALayer shadow doesn't work with gradients, and I am lost. Any help is

问题 I came across Sweep Gradient on Android and was intrigued if it could give me a better control over the Color spacing and transitions. Did a quick search and found almost nothing about it!! The only few references I found (and they do not meet the criteria of coming even close to explaining it properly or comprehensively) are listed below : Sweep Gradient on Android (which only mentions commands to use - which is of almost no worth since right now I have no clue what Sweep Gradient is!)

问题 I have a text and I want to set a gradient color as its foreground. May I do it in xml? Or should I do it in activity? I am programming with Kotlin in Android Studio. activity_main.xml <androidx.constraintlayout.widget.ConstraintLayout xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:android="http://schemas.android.com/apk/res/android"> <TextView android:layout

问题 I am working with complex-valued neural networks. For Complex-valued neural networks Wirtinger calculus is normally used. The definition of the derivate is then (take into acount that functions are non-Holomorphic because of Liouville's theorem): If you take Akira Hirose book "Complex-Valued Neural Networks: Advances and Applications", Chapter 4 equation 4.9 defines: Where the partial derivative is also calculated using Wirtinger calculus of course. Is this the case for tensorflow? or is it

问题 I want to create a checkerboard pattern using gradients. I've found an example and modified it to my needs, however it only works with -moz prefix. When I remove the -moz prefix, the pattern is completely different. How can I make this -moz checkerboard pattern work with unprefixed linear-gradient ? body { background-image: linear-gradient(45deg, #808080 25%, transparent 25%), linear-gradient(-45deg, #808080 25%, transparent 25%), linear-gradient(45deg, transparent 75%, #808080 75%), linear
