问题描述

我正在尝试在图像上应用USM锐化滤镜。我正在使用C＃.Net（FrameWork 4.0）和VS 2012.我尝试了这段代码，我也得到了输出图像，但只有1-2秒，之后就出现了这个错误。我测试了一切，但未能解决。任何人都帮助我离开这里。

提前谢谢。



我是什么尝试过：

I am trying to apply "Unsharp Mask" filter on an image. I am using C#.Net(FrameWork 4.0) and VS 2012. I tried this code, I am also getting the output image but only for 1-2 seconds, after that this error is coming. I tested everything but failed to solve.can anyone help me out of here.
Thank you in advance.

What I have tried:

public void unsharp()
{
Oimg = (Bitmap)file.Clone();//input image
for (int x = 0; x < Oimg.Width; x++)
{
for (int y = 0; y < Oimg.Height; y++)
{
Color pixel = Oimg.GetPixel(x, y);

int r = pixel.R;
int g = pixel.G;
int b = pixel.B;

int[] Oarray = new int[] { r, g, b };//input image array

int[] Rarray = new int[Oarray.Length];//resultant image array

newBitmap = (Bitmap)pictureBox1.Image;//filter applied image
for (int m = 0; m < newBitmap.Width; m++)
{
for (int n = 0; n < newBitmap.Height; n++)
{
Color p = newBitmap.GetPixel(m, n);//Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
int r1 = p.R;
int g1 = p.G;
int b1 = p.B;

int[] newarray = new int[] { r1, g1, b1 };//filter applied image array

for (int e = 0; e <= Oarray.Length - 1; e++)
Rarray[e] = Oarray[e] - newarray[e];

//convert array to bitmap
Bitmap Rbmp = new Bitmap(pictureBox1.Width, pictureBox1.Height);
int stride = pictureBox1.Width * 4;
unsafe
{
fixed (int* intPtr = &Rarray[Oarray.Length-1])
{
Rbmp = new Bitmap(pictureBox1.Width, pictureBox1.Height, stride, PixelFormat.Format32bppRgb, new IntPtr(intPtr));
}
}
newBitmap = (Bitmap)Rbmp.Clone();
pictureBox1.Image = newBitmap;
}
}
}
}
}

推荐答案

你问了一个相关的问题：如何解决这个问题 指数数组的边界之外。错误？ [ ^ ]今天早上，我告诉你要使用调试器。

这是唯一可以告诉你错误的工具：这取决于图片中的数据而我们无法访问它。



所以在该方法的第一行放置一个断点，然后开始研究它，看看发生了什么 - 这是你要解决这个问题的唯一方法！

When you asked a related question: How to solve this " index was outside the bounds of the array." error ?[^] this morning, I told you to use the debugger.
It's the only tool that can tell you what is wrong: this depends on the data in your image and we do not have access to it.

So put a breakpoint on the first line of that method, and start working your way through it, looking at what is going on - it's the only way you are going to solve this!
