如何使用java找出图像中心及其x，y坐标？
问题描述：
我正在尝试使用java语言旋转图像矩阵45,90,180,270和360
所以我将在下一个链接应用方程式来旋转矩阵
http：//主页。 inf.ed.ac.uk/rbf/HIPR2/rotate.htm [ ^ ]
但我认为（x0，y0）是图像中心的坐标
i需要计算这个中心
如果有人能帮忙那就太棒了！
问候！
I'm trying to rotate image matrix 45,90,180,270 and 360 using java language
so i will apply the equations in next link to rotate matrix
http://homepages.inf.ed.ac.uk/rbf/HIPR2/rotate.htm[^]
but i think (x0,y0)are the co-ordinate of the center of image
i need to calculate this center
If anyone could help that would be great!
Regards!
答
中心很简单：
Center is easy:
X Center: X(Top Left) + (Width / 2)
Y Center: Y(Top Left) + (Height / 2)
