问题描述

我有一个图像视图，在获取图像并设置图像视图后，我遇到了一个简单的问题。

I have an image view, and after getting the image and setting the image view I am having a simple problem.

取决于它是横向还是纵向，如果图像视图是方形，则不会填充图像视图。我使用风景照片实现这一目标的唯一方法是基本上裁剪它，否则它会被拉伸。

Depending on if it is landscape or portrait, and if the image view is a square, the image view will not be filled. The only way I can achieve this using a landscape photo is to essentially crop it, otherwise it is stretched.

麻烦的是 - 通过将照片裁剪成一个方形我然后可以调整大小 - 我最终失去了我裁剪的区域，为不完整的照片腾出空间。

The trouble is - by cropping the photo into a square that I can then resize - I end up losing the areas that I have cropped, making way for an incomplete photo.

或者，我可以强制图像填充视图，但是它最终会在这个过程中被拉长。

Alternatively, I could force the image to fill the view, but it will end up being stretched in the process.

无论如何要实现这个目标吗？我已经查看了imagefactory，但运气不好。

Is there anyway to achieve this? I have already looked at imagefactory, but haven't had much luck.

谢谢

推荐答案

这里有一种方法可以使imageView与图像完全一致，因此不会出现裁剪或模糊。为此需要使用临时图像

Here goes a method for making an imageView exactly of image so it does not get crop or blur.You have to use a temporary image for this purpose

var imageTemp = Ti.UI.createImageView({
  image : someFile.read(),
  height:'auto',
  width:'auto'
});
Ti.API.info( "height=" + imageTemp.size.height);
Ti.API.info( "width=" + imageTemp.size.width);
imageTemp = null;

谢谢
