gradient

问题 I need to make the titles in BottomNavigationView in android be of a gradient color. <?xml version="1.0" encoding="utf-8"?> <gradient xmlns:android="http://schemas.android.com/apk/res/android" android:startColor="@color/gradientLeft" android:endColor="@color/gradientRight" android:angle="0"/> I have the colors set up and it works with e.g. icons on BtmNavView, but I can't get the titles to change their color to a gradient. <com.google.android.material.bottomnavigation.BottomNavigationView

问题 I tried to add a (radial) gradient as background (in Android 4.0), either as background image or programmatically but none of them never works. I can only test it in emulator, but I guess it's the same on a 4.0 device. These solutions don't work: Placing in raw folder. (Disable Android resource / image / png optimization) Making a proxy xml with dithering and anti aliasing true, as well as saving opacy of png to 99%. (android:dither="true" does not dither, what's wrong?) Overriding

问题 I have a page with multiple backgrounds: one with gradient and one with texture pattern. But background-blend-mode doesn't work. Chrome appears to show only gradient layer. When I try to blend two background-images or background-image with solid background-color it works well. But not with gradient. Is something wrong? body { width: 100%; height: 100%; background: url('../images/noisy.png'); background-color: rgba(29, 84, 140, 1); background: -webkit-radial-gradient(center, ellipse cover,

问题 I was trying to use tfrecords to train the PNet of MTCNN. At first the loss was decreasing smoothly for the first few epochs and then it became 'nan' and so did the model weights. Below are my model structure and training results: def pnet_train1(train_with_landmark = False): X = Input(shape = (12, 12, 3), name = 'Pnet_input') M = Conv2D(10, 3, strides = 1, padding = 'valid', kernel_initializer = glorot_normal, kernel_regularizer = l2(0.00001), name = 'Pnet_conv1')(X) M = PReLU(shared_axes =

问题 I am currently, learning the working of Seam Carving aka Content Aware Resizing . Seam Carving involves calculation of Energy of Each individual pixel in an image. Where the Energy could be calculated using several methods, one of which being Gradient Magnitude (Image Gradient). I have previously used Sobel Filter/Operator , which involves calculation of gradients in X and Y direction, where the output of the two is used for finding edges. But, I am not quite sure what a Gradient is by

问题 My question is how to fix rendering issues in Safari 14 related to a combination of multiple background gradients ( linear and radial ), background-attachment ( local and scroll ) and ``mix-blend-mode`. Please see example: https://codepen.io/astro87/pen/LYRQNbd?editors=1100 Correct rendering in Google Chrome Background gradient visible on the right edge: Scroll a bit to the right and see background gradient is visible on the left and right edge: Scroll completely to the right edge and see

问题 How do I develop a gradient in JavaFX that looks like the one below? 回答1: Use linear-gradient in CSS : linear-gradient(to (top, right, bottom, left) , (color begin) , (color finish) ); -fx-background-color: linear-gradient(to top,-color-amber, transparent); 来源： https://stackoverflow.com/questions/40532924/gradient-in-javafx

问题 Have been trying to build a pie/donut chart with smooth gradient on it but figured out that it's quite difficult to make. Already spent a lot of time and still haven't any luck how to resolve that problem. I'm using d3js library I have something similar to this And want to fill it with gradient, exactly like this Any advice how to make it more close to it. Maybe someone of you have already faced with that issue and have some knowledge about it. Will be appreciate for any answers and advices.
