Java 将彩色png布局图像中的图案读取到数组中？,java,arrays,bitmap,Java,Arrays,Bitmap,因此，我想读取图像，并用0-6自动填充我的int[]layout数组。整个图像为896（宽）x 992（高），每个磁贴为32x32像素大 每个磁贴上都有1px的边框，因此颜色为30x30像素大。 这是我到目前为止的java代码（只有Grid.class）： }以下是一步一步的解决方案： 研究以下内容： javax.imageio.imageio.read（新文件（“filename.png”） java.awt.image.BufferedImage.getRGB（intx，inty） 加载并读

因此，我想读取图像，并用
0-6
自动填充我的
int[]layout
数组。整个图像为
896（宽）x 992（高）
，每个磁贴为
32x32像素
大

每个磁贴上都有1px的边框，因此颜色为
30x30像素
大。

这是我到目前为止的java代码（只有
Grid.class
）：

}以下是一步一步的解决方案：

  • 研究以下内容：

    javax.imageio.imageio.read（新文件（“filename.png”）

    java.awt.image.BufferedImage.getRGB（intx，inty）
  • 加载并读取该图片。最好是从每16个像素获得一种颜色（具有32x32个平铺-因此从平铺中间读取是安全的）

  • 比较颜色是否与图案中的颜色匹配
  • 如果匹配，则写入您的
    布局[i][j]
    数组
  • 重复这个循环，直到你到达一张照片的末尾。（不要忘记在一个周期结束时
    i++；
    和
    j++；
    ）
  • 你有一个结果。只要在28x31阵列中循环，就有868个操作，所以不要担心速度
    • 您还可以将数组初始化为
    layout=new int[28][31]；
    而不需要大量的0。确切的问题是什么？太好了！我搜索了这个
    getRGB（int x，int y）
    ！！谢谢：）
