在C＃中使用缩放和裁剪来调整图像大小

[英]Resize image with scale and crop in C#

原文 2014-03-29 08:44:40 2 2 c#/ .net/ image/ image-processing

When I upload an image, it is quite big some times, I have to create its thumbnail in a specific way. 上传图像时，有时它会很大，因此必须以特定方式创建其缩略图。

What I want is if I declare the size of 96x69 for the thumbnail, those uploaded images which are scalable to this resolution should be scaled, and those uploaded images which are quite different in wxh , example 1000x1000 , they should be cropped to maximum better scalability. 我想要的是，如果我声明缩略图的大小为96x69 ，则应缩放可缩放到此分辨率的那些已上传图像，并且那些在wxh中完全不同的上传图像（例如1000x1000 ）应裁剪为最大的更好可缩放性。 Is there any fast library or built in code as I have tried to do in my own way but it is not that perfect? 是否有快速的库或内置的代码，以我自己的方式尝试完成，但不是那么完美？

I strongly recommend ImageResizer which can be found freely on the Nuget . 我强烈建议您在Nuget上免费找到ImageResizer 。 Basically, resizing images is a sophisticated procedure that may be included variety techniques such as cropping, scaling, resizing, moving, trimming, etc. that implementing each of these methods is not an easy job. 基本上，调整图像大小是一个复杂的过程，可能包含多种技术，例如裁切，缩放，调整大小，移动，修剪等，实现这些方法中的每一个都不容易。 Hence, it's better to use image-resizer. 因此，最好使用图像缩放器。
