推荐答案

根据您的问题，看起来像您想要的在较大的图片中查找较小的图片，然后将图像裁剪为内部的较小图片.

首先，这是一篇很棒的CP文章，介绍如何使用图像(包括裁剪):
使用C#进行图像处理 [ http://www.dreamincode.net/forums/topic/201783-c%23-trying-to-find-a-smaller-image-inside-a-larger-image-need-help/ [ ^ ]

Based on your question, it looks like you want to find a smaller picture inside a larger picture and then you want to crop the image to be just the smaller image inside.

To start with, here is a great CP article on how to work with images (including cropping):
Image Processing using C#[^]

To find that smaller image, if you don''t know the coordinates and you don''t want the user to draw a box on the screen to indicate the coordinates (which would be best, by the way), you could try to find the right place by looking for a particular pattern of pixels (say a box around the picture). Here is a post that might have some useful code that you could start from:
