Java在屏幕上找到图像

问题描述

你们可以给我一些关于如何在屏幕上找到图像的提示。我的意思是，一个简单的像素组合。例如，它找到30x30像素白色方块的坐标。

Can you guys give me hints on how to find a image on screen. I mean, a simple pixel combination. For exmaple, it finds coordinates of 30x30 pixel white square.

Java机器人类允许我找到某些像素的颜色。但我需要反对，我希望我的程序扫描我的屏幕，然后告诉我这个小图像的坐标。好吧，我可以通过机器人检查所有像素，但它应该比这更快。更快。

Java robot class allows me to find color of certain pixel. But i need to opposite, I want my program to scan my screen and then tell me the coords of this little image. Well I could go through all pixels with Robot, but it should be faster than that. Much faster.

有任何建议吗？

推荐答案

我担心这正是你必须要做的。

I'm afraid that that's precisely what you'll have to do.

如果所有像素都应为白色，则可以先取30个像素宽的步长，如果找到白色像素，则说5个像素步长，然后如果这些像素也是白色，请检查剩余像素广场。

If all pixels should be white, you could first take 30 pixel wide steps and if you find a white pixel, take say, 5 pixel steps, and then if these pixels are white too, examine the remaining pixels in the square.

这样的事情：

         ...... 
         .  .  .  .
