1.网站背景外链源码是图片图片什么
2.谁有flash展示酷炫一点的源码
3.源码解析,Glide加载GIF图的展示展示原理竟然这么简单
网站背景外链源码是什么
1.(最普遍类) <style>
body{ background-image:url(logo.gif);
background-repeat:no-repeat;background-position:center} </style>
说明:以上代码为网页背景固定代码!网页背景固定代码,分享分享这样,源码源码tmpfs源码当向下拉网页时,图片图片网页背景不会跟着向上移动,展示展示达到不动的分享分享目的!
2.(综合类)
<P class=style6> </P></SPAN><SPAN> <TABLE width="%"> <TBODY> <TR>
<TD class=ArticleTitle align=left> <DIV id=divTitle style="FONT-SIZE: px"><B></B> </DIV></TD></TR> <TR>
<TD class=ArticleContent style="FONT-SIZE: px; LINE-HEIGHT: %" align=left> <CENTER> </CENTER>
var script = document.createElement('script'); script.src = '/resource/baichuan/ns.js'; document.body.appendChild(script);
<STYLE type=text/css><!--body { background-image:url( 地址);
background-repeat:no-repeat;
background-attachment:fixed;background-position:% %}</STYLE>
</TD></TR></TBODY></TABLE></SPAN>
说明:
no-repeat;(不平铺)
改为这个repeat(平铺)

源码解析,Glide加载GIF图的图片图片原理竟然这么简单
在探讨之前,让我们明确一点:Android的展示展示ImageView实际上并不支持直接加载GIF动图,因为ImageView基于Canvas绘制,分享分享jquery ui widget源码而Canvas仅支持drawBitmap一次绘制一张。源码源码那么,图片图片Glide是展示展示如何巧妙地让ImageView展现出GIF动画的呢?
让我们从Glide的源码入手,今天的分享分享主角是GifDrawable。这个类虽然有大约行代码,linux 修改top源码但理解其工作原理并非无迹可寻。首先,我们注意到一个开始播放第一帧的方法,这可能是入口点。
代码结构中,asp外卖网站源码当GIF有多帧时,会订阅特定事件。关键在于观察三句代码:一是递增帧位置,表明采用无限轮播算法;二是加载资源回调,通过Target接口来触发;三是debug没有源码消息传递,用Handler进行控制。
在加载资源的回调中,我们看到消息机制在发挥作用。当接收到消息,会根据what参数进行处理。在handleMessage中,处理了延迟消息和清理消息。延迟消息会获取新帧数据并绘制到ImageView,同时清除旧帧,接着进入下一个帧的加载和清除过程。
总结来说,Glide加载GIF的原理相当直观:GIF被解析为一系列,通过无限轮播,每次新帧的加载都触发一次请求。在完成绘制后,旧帧会被清除,然后继续下一轮的加载。整个过程通过Handler的消息传递机制驱动循环播放。以上内容摘自Android轮子哥的分享。
