Why is this, and can it be fixed?P.S. Opera 11.10 on Ubuntu 10.10
推荐答案
要找出为什么你的图片有时候看起来像在Opera的Turbo一团糟,你应该学习歌剧涡轮增压的工作原理(其实,什么是Turbo模式)。
To find why your images sometimes look like a mess in Opera Turbo, you should learn how Opera Turbo works (actually, what is Turbo mode).
如你所知,歌剧涡轮来为慢速连接非常方便。为了提高网页歌剧涡轮COM presses的加载速度它的内容。更小的数据量意味着更快的加载。
As you know, Opera Turbo comes very handy for slow connections. To increase loading speed of web pages Opera Turbo compresses it's content. Smaller amount of data means quicker load.
有对这个问题的根源与您的图像。
There's root of this issue with your images.
据文件
当启用歌剧涡轮,网页
是的 COM pressed通过Opera的服务器等等
它们使用比少得多的数据
原稿。这意味着有
少下载,所以你可以看到你的
网页更快速。
因此,当您尝试使用Turbo模式访问某些网页,歌剧院服务器从原来的位置需要的数据(下载完整的网页),玉米presses它在服务器端和发送融为一体pressed给您(或任何其他涡轮增压的客户)。
So when you try to access some page using Turbo mode, Opera server takes data from original location (downloads complete webpage), compresses it on server side and send it compressed to you (or to any other Turbo's client).
是啊,在Turbo模式下的图像可以看到是不是原来的图片,这只是COM pressed距离Opera服务器映像。
Yeah, in Turbo mode image you can see is not original image, that's just compressed image from Opera server.
如果要模拟这个问题,尝试用Photoshop的PNG图像(或任何其他照片编辑器)转换成COM pressed JPEG格式,你会得到类似于从歌剧涡轮你的榜样东西。
If you want to simulate this issue, try to convert that PNG image with Photoshop (or any other photo editor) into compressed JPEG format and you'll get something similar to your example from Opera Turbo.
带宽优化
歌剧涡轮COM presses Web流量通过
80%发挥的淋漓尽致网
资源和提供更好的
浏览体验。
在Turbo模式您的图片COM pressed低画质设置(我猜1-5)。这使得他们更小的尺寸(有显著的图像质量损失)和提高加载速度即可。
In Turbo mode your images are compressed with low image quality setting (I guess 1-5). That makes them smaller size (with significant image quality loss) and that increases loading speed.
这是Opera Turbo,更主要的目的!
这是回答你的问题:为什么是这样的第一部分。在能不能固定的部分答案是否,它不能被固定即可。为什么?由于歌剧院Turbo模式并不像其他正常的浏览器。
另一个报价:
That was answer to first part of your question "Why is this". Answer on "can it be fixed" part is No, it can't be fixed. Why? Because Opera in Turbo mode doesn't work like any other normal browser.
Another quote:
当打开时,歌剧涡轮
玉米presses图像和使
加载速度非常快。我有一点点想法
这是如何工作的,并期待
在收到消息灵通的意见
如何化模式。
通常,当您访问任何页面,
浏览器将开始获取图像
从该服务器。与Opera Turbo上,
图像将首先被下载到
Opera的服务器,然后COM pressed。
然后,图像将被投放到
浏览器。
Typically, when you access any page, the browser will start fetching images from the server. With the Opera Turbo, the images will first be downloaded to Opera's servers and then compressed. The images will then be served to the browser.
在CrazyEngineers论坛上,我也发现了这个...
On CrazyEngineers forum I also found this...
我试过涡轮模式
CrazyEngineers和图形(PNG
文件)看起来有些变形了。
这就是像这样的你有相同的问题。
