由 懵懂的女人 提交于 2021-01-29 10:37:56
问题 I was recently playing with some Javascript - and I was trying a create a small slideshow using only Vanilla Javascript with no libraries such as jQuery - in fact in this small project I want to learn how to use and implement it in real website. Here is my HTML markup: <body onload="changeImage()"> <div class="logo"> <img src="logo.png" class="logo_image" id="imageholder"/> </div> My idea was to use a HTML div container with img tag in it - in each iteration in Javascript program the image

问题 According to my logic, on tap gesture to the image it should be changed with fade animation, but actual result is that image changes without animation. Tested with Xcode 11.3.1, Simulator 13.2.2/13.3 if it is important. P.S. Images are named as "img1", "img2", "img3", etc. enum ImageEnum: String { case img1 case img2 case img3 func next() -> ImageEnum { switch self { case .img1: return .img2 case .img2: return .img3 case .img3: return .img1 } } } struct ContentView: View { @State private var

问题 I want to make a slideshow where the pictures transition through fade in fade out opacity. it just glooms on the screen and switches to the next picture. I got it to work but added the other brower webkits and it stopped working. Can't seem to find my mistake.. The slideshow still works. This is the code: /* Fading animation in css */ .fade { -webkit-animation-name: fade 5s; animation-name: fade 5s; -moz-animation: fade 5s; -o-animation: fade 5s; } @-webkit-keyframes fade { 0% {opacity: 0.2}

Blending images in java

问题 Well I've got my game engine running smoothly, and perfectly on all machines! Before I continue adding functionality to the engine, I want to enhance the engine's graphical capabilities. The one I'm focused on is fading and blending images. I'm going to need some smooth transitions, so without using any 3rd party libraries like OpenGL, how does one apply opacity to images when drawing to a graphics object? thanks for any replies :D 回答1: Perhaps using an AlphaComposite could be what you're

How to make a label fade in or out in swift

由 僤鯓⒐⒋嵵緔 提交于 2019-12-18 11:54:02
问题 I am looking to make a label fade in, in viewDidLoad() , and then after a timer is at 3 fade out. I am not familiar with the fadein or fadeout functions. How would I go about doing this? 回答1: Even though the view has loaded, it may not be visible to the user when viewDidLoad is called. This means you might find your animations appears to have already started when you witness it. To overcome this issue, you'll want to start your animation in viewDidAppear instead. As for the fadeIn and fadeOut

fading edges working only on top and left

由 倖福魔咒の 提交于 2019-12-10 18:48:08
问题 I made a custom ImageView that supports basic scrolling through calls to View.scrollBy() in a GestureDetector . I wanted to add some feedback on the reaching of scrolling bounds so I enabled fading with: setVerticalFadingEdgeEnabled(true); setHorizontalFadingEdgeEnabled(true); but the fading works as I expected only on top and left edges, while bottom and right ones don't fade. I'm sure those edges aren't off screen because the view is set to fill_parent in height and width. So what's wrong?

Clean way to implement gradual fading of brightness in Android?

问题 At the moment I have code to fade brightness adjustments which looks something like this: new Thread() { public void run() { for (int i = initial; i < target; i++) { final int bright = i; handle.post(new Runnable() { public void run() { float currentBright = bright / 100f; window.getAttributes().screenBrightness = currentBright; window.setAttributes(window.getAttributes()); }); } try { sleep(step); } catch (InterruptedException e) { e.printStackTrace(); } } } }.start(); I'm not sure if that's

Java Fade In and Out two JPanels at the same time

由 徘徊边缘 提交于 2019-12-04 05:17:27
问题 I have a list of JPanels that I want to display as a "slideshow" where one JPanel fades out and the next JPanel in the list fades in. This is the code I am fiddling with: public float opacity = 0f; private Timer fadeTimer; private boolean out; public void fadeIn() { out = false; beginFade(); } public void fadeOut () { out = true; beginFade(); } private void beginFade() { fadeTimer = new javax.swing.Timer(75,this); fadeTimer.setInitialDelay(0); fadeTimer.start(); } public void actionPerformed
