在Java中逐像素访问图像(Accessing Image pixel by pixel in Java)

在Java中逐像素访问图像(Accessing Image pixel by pixel in Java)

是否有任何内置的Java API或类库来访问给定图像中的像素？ 我打算做的是在另一张图片中搜索一张图片。 例如：img1是24x24px，img2是1024x768px假设img2中可能存在类似于img1的符号。 现在我想获得与img1类似的符号的X和Y坐标。

Is there any inbuilt java API or class library for accessing pixels in a given image? What I am planning to do is search one image inside another image. For example : img1 is 24x24px , img2 is 1024x768px assume that a symbol, similar to img1 may exists in img2 . Now I want to get X and Y coordinates of the symbol which is similar to the img1.

是的，如果将图像作为BufferedImage则使用getRGB(int x, int y)方法获取位置（x，y）上像素的值。

请参阅java.awt.image.BufferedImage的API文档。

Yes, there is, if you have your image as a BufferedImage then use the getRGB(int x, int y) method to get the value of the pixel at the position (x, y).

See the API documentation of java.awt.image.BufferedImage.
