帮助减去两个图像 [英] Help in subtraction of two images

问题描述

帮助！
将两个图像按像素相减会给我一个错误:

Help!
The subtraction of two images by pixel gives me an error:

int h, w;
h = pictureEdit1.Image.Height;
w = pictureEdit1.Image.Width;
Bitmap b = new Bitmap(h,w );


Bitmap p1 = (Bitmap )pictureEdit1.Image;
Bitmap p2 = (Bitmap)pictureEdit2.Image;
try
{
    for (int x = 0; x <= pictureEdit1.Image.Height; x++)
    {
        for (int i = 0; i <= pictureEdit1.Image.Width; i++)
        {

            if (p1.GetPixel(i, x) != p2.GetPixel(i,x))
            {
                 pictureEdit1.Image.Height.ToString());
                b.SetPixel(x, i, p2.GetPixel(x, i));

            }
            //else
            //{
            //    b.SetPixel(x, i, Color.Red);
            //}


        }
    }

}
catch (Exception ex)
{
    MessageBox.Show(ex.Message);
}
pictureEdit3.Image = b;

推荐答案

似乎您在那儿交换了宽度和高度.您以x轴为picture1的高度，以y轴为picture1的宽度.应该是另一种方式.那是那里最明显的事情.您的代码中可能存在或没有其他问题-很难说.


~~~~~~~~

好的，即使在最上面，您也正在创建一个新的位图，将其宽度-高度互换，所以也许您打算那样做?代码相当混乱.

It seems you swapped up width and height there. You take picture1''s height for the x axis and picture1''s width for the y axis. It should be the other way. That was the most obvious thing there. There may or may not be other issues in your code - hard to say.


~~~~~~~~

Okay, even on top, you are creating a new Bitmap with the width-height swapped, so perhaps you intended it that way? The code is rather confusing.

我认为是您的循环使您绊倒.

看一下外部循环，您已经使用过 <= 和 .Height +1

看一下内部循环，您已经使用过 <= 和 .Width

它们应该被同等对待.

我想您会在两个循环中都使用 < 和 .Height 或 .Width .

I think it is your loops that are tripping you up.

Look at the outer loop, you have used <= and .Height +1

Look at the inner loop, you have used <= and .Width

They should both be treated the same.

I would think you would want to use < and .Height or .Width for both the loops.

伙计，您那里有些奇怪的事情.

首先，按照惯例，使用变量"x"进行遍历，使用"y"进行遍历.不是"i".

出现此错误似乎是因为您超出了高度范围，在这里循环:

Man, you''ve got some strange stuff going on there.

Firstly, by convention use a variable ''x'' to go across and ''y'' to go up. Not ''i''.

The error looks like it comes about because you''re going out of range on the height, looping here:

for (int x = 0; x <= pictureEdit1.Image.Height+1; x++)

当然应该是:

surely should be:

for (int y = 0; y < pictureEdit1.Image.Height; y++)

仍然不确定要做什么.

另外，位图"b"-宽度总是在高度之前-您是在侧面对其进行构造...

Still not sure what you want to do mind.

Also, the bitmap ''b'' - width always comes before height - you''re constucting it on its side...
