- 动态调整大小/裁剪图片 [英] - Dynamically Resizing/Cropping Pictures
问题描述
我需要在一个固定的维度空间中显示一堆各种尺寸的图片
，就像MSN Messenger在其聊天时用其用户照片
窗户。
强制图像尺寸会扭曲比例，所以'没有用。
强制一个坐标，而另一个坐标保持灵活将保持
比例，但x，y值不会在图片之间保持一致。
我认为MSN Messenger方法带来一个坐标为
100像素，然后只显示其他
坐标的PART信息。我不确定你们是否知道我在说什么，但
Messenger会缩小（例如）宽度为100像素，保持高度
比例，但只显示高度的中间100个像素（或者是相反的另一种方式是
）。
我该怎么办？相似的东西？也许涉及将图像放置为
背景而不是前景元素？
如何重新创建用于显示图像的MSN Messenger公式
恒定尺寸而不会丢失比例（但丢失不必要的
图像部分）？
谢谢。

对不起，不是一个选项。
如果有人有任何优惠，仍在寻找以下问题的帮助！

为什么不呢？

对不起，不可能。您可以通过将
图像编码为居中的背景图像到固定宽度的块级
元素来实现统一尺寸，但是没有办法调用浏览器调整大小机制
用于背景图片。

I need to display a bunch of pictures that are all of various dimensions
into a fixed dimension space, like MSN Messenger does with its user photos
in the chat windows.
Forcing image dimensions will warp the proportions, so that''s no good.
Forcing one coordinate while leaving the other flexible will maintain
proportions, but the x,y values won''t be consistant from picture to picture.
I considered the MSN Messenger method of bringing one of the coordinates to
100 pixels, and then showing only PART of the information of the other
coordinate. I''m not sure if you guys know what I''m talking about, but
Messenger will shrink (for example) the width to 100 pixels, keep the height
proportionate, but only show the middle 100 pixels of the height (or is it
the other way around? no matter).
How can I do something similar? Perhaps involving placing an image as a
background instead of a foreground element?
How can I recreate the MSN Messenger formula for displaying images in
constant dimensions without losing the proportions (but losing unnecessary
sections of the image)?
Thanks.

Browsers do a poor job when resizing images, better change the actual
images.

Sorry, not an option.
Still looking for help on the below problem, if anyone has any to offer!

Why not?

Sorry not possible. You can achieve the uniform dimensions by coding the
image as a centered background image to a fixed width block level
element, but there is no way to invoke the browsers resizing mechanism
for background images.
