新浪科技讯 北京时间2月1日下午消息,国外科技网站W3Techs的最新调查显示,PNG现已超越GIF,成为最受欢迎的互联网图像文件格式。
数据显示,目前多达62.4%的网站都采用PNG格式,令其以微小优势领先于GIF格式(份额为62.3%)。而就在一年前,GIF的份额还比PNG多出15%。
虽然我们以前提到的GIF专利问题早已得到解决,但由于PNG在技术上更胜一筹,所以相比于GIF格式,它现在更受网络管理员们的欢迎。通常情况下,用PNG格式制作的图像文件更小,同时还支持更为广泛的颜色深度及透明度选项。
GIF唯一占优的功能是,它支持动画。但大多数人发现,网站上的GIF图标看上去好像15年来从未更新过。现如今,动画主要用于广告。
令人感兴趣的是,在1000家流量最大的网站上,GIF仍然比PNG更受欢迎,份额之比为67.9%和66.3%,但这种情况可能会在未来几个月发生改变,因为目前的趋势很明显:从GIF 向PNG转换的网站数量,是从PNG向GIF的网站数量的三倍。
另外,在不同的地区,网站采用PNG格式的比率也大相径庭。在法国、意大利、西班牙和荷兰等欧洲国家,PNG的使用率超过了70%,但在亚洲却少得多,日本为41%,韩国为34.6%,中国为30.6%。
同时,使用Unix类开源系统的用户要比Windows用户更推崇PNG格式,而谷歌更是这种图像文件格式的忠实拥趸,在谷歌旗下各类服务器中,PNG的使用率竟然高达95.6%。
GIF图像格式由CompuServe在25年前开发,是互联网发展早期一项非常重要的标准。GIF可能还会存在25年,但遗憾的是,它现在已失去了最流行图像文件格式的桂冠。(扬帆)
