animated-gif

问题 I'm quite sure this is an old problem. This is how i render my animated gif: <img id='loading' alt='loading' style="display: none; position: relative; left:10px; top:2px;" src="<%= Url.Image("loading.gif") %>" /> This is how I'm desperately trying to show it at the moment: showLoading: function(gifId, butId) { var n = gifId != undefined ? gifId : 'loading'; var l = $('#' + n); //if browser is stupid if ('v' == '\v') { var s = l.attr('src'); var x = document.getElementById(n); x.style

问题 I have a program that loads a spritesheet, creates BufferedImages of each frame on the sheet, and writes it to an animated gif. Using the class provided by Elliot Kroo on Creating animated GIF with ImageIO?, I was able to successfully output a file. However, the gif doesn't animate quite right. The sheet I provided was a .png with a transparent background, so every subsequent frame is just put on top of the last frames, with differences showing through the transparent background (Example).

问题 I'm trying to make a program to display an animated GIF using Tkinter. Here is the code that I originally used: from __future__ import division # Just because division doesn't work right in 2.7.4 from Tkinter import * from PIL import Image,ImageTk import threading from time import sleep def anim_gif(name): ## Returns { 'frames', 'delay', 'loc', 'len' } im = Image.open(name) gif = { 'frames': [], 'delay': 100, 'loc' : 0, 'len' : 0 } pics = [] try: while True: pics.append(im.copy()) im.seek(len

问题 Icon icon = new ImageIcon(getClass().getResource( "/img/icon.gif" ) ); aButton = new JButton("Its a button", icon); Is there some kind of method that can stop an animated from playing? I was thinking of assigning a static jpg of the gif, then when I hover, assign the animated gif, but I don't think there is an event for taking off mouse in MouseMotionListener so I can load back the static jpg. The gif loops in the button, however, if I hover over it, it disappears. How can I make the gif

问题 I have an animated gif banner on my website that is around 2MB. For people with slow connections, I want to include some Javascript that will only display (and start playing) this gif when it is fully loaded, so that the rest of the website will already display whilst the gif is still loading. Ideally, I would have one image (loading.gif) be displayed first, and then switched to the banner (banner.gif) with javascript when banner.gif is loaded. How do I do this? (I'm new to Javascript) Thanks

问题 Is it possible to restart a gif animation without downloading the file every time? My current code looks like this: var img = new Image(); img.src = 'imgages/src/myImage.gif'; $('#id').css('background-image', 'url("' + img.src + '?x=' + Date.now() + '")' ); Edit When I insert the gif into the dom it didn't restart the gif animation. I can only achieve this by appending a random string to the image src but this will download the image again. I want to know if it is possible to restart the gif

问题 I have an event that gets called when my app uses the internet. The event changes an animated gif composed of 7 frames. How do I make it only loop through the frames only once? private void trafficSendingActive(object sender, trafficEventArgs e) { txImage.Image = Properties.Resources.blip; } 回答1: You could use the System.Drawing.ImageAnimator to start/stop the gif animation // start System.Drawing.ImageAnimator.Animate(txImage.Image, OnFrameChanged); // stop System.Drawing.ImageAnimator

问题 I need a function that adds a watermark to an animated gif. How I can do that with PHP and ImageMagick? This is my code, but it doesn't work. function IMagickWatermark($sf, $sfDest, $sfLogo, $sGravity='southeast'){ //$sCmd = "composite -compose bumpmap -gravity $sGravity $sfLogo \"$sf\" $sfDest"; $sCmd = "convert \"$sf\" -coalesce -gravity south -draw 'image over 0,0 0,0 \"$sfLogo\"' \"$sfDest\""; exec($sCmd); return 1; } $sf = $_SERVER['DOCUMENT_ROOT']."/test/source.gif"; $sfDest = $_SERVER[
