获取图像的特定部分（图） [英] Getting a particular Portion of Image (Picture)

问题描述

我要剪切的图像的特定部分，并用它来裁剪后的图像与另一存储在HDD比较。问题是，我不知道如何让源图像的特定部分。我知道位置（X，Y）的图像进行裁剪。

I want to cut the the specific portion of the the picture and use it to compare the cropped image with another stored in the HDD. The problem is that I don't know how to get a specific section of the source image. I know the location (X,Y) of the image to be cropped.

推荐答案

这将加载原始，并创建一个播种的版本开始在（0,0）和64×64的尺寸。

This will load the original and create a cropped version starting at (0,0) and with dimensions of 64x64.

Bitmap original = new Bitmap( @"C:\SomePath" );
Rectangle srcRect = new Rectangle( 0, 0, 64, 64 );
Bitmap cropped = (Bitmap)original.Clone( srcRect, original.PixelFormat );

顺便说一句，你不指定，如果这是的WinForms或WPF，与WinForms的那么回事，因为我真的不知道WPF图像处理功能。

BTW, you don't specify if this is WinForms or WPF, so going with WinForms as I don't really know WPF image manipulation functions.
