有没有办法调试使用图片？ [英] Is there a way to debug using pictures?

问题描述

我正在编写一个使用图片的程序。我处理一个图像（用函数说"function1（）"，在这个处理结束时我展示它

I am writing a program that uses pictures. I process an image (with a function say "function1()" and at the end of this processing I show it

picImage.Image = bmp;

一切进展顺利。但我现在想调试这个function1进程。这个过程涉及迭代，显示的图像是n次迭代后的结果。

Everything is going well. However I now want to debug this function1 process. This process involves a iteration, and the image that was shown is the result after n iterations.

我想通过显示图像每次迭代的变化来调试这个过程。 

I would like to debug this process by showing how the image changes for every iteration. 

然而在visual studio中我注意到在调试时，图像在操作结束并且GUI线程再次负责之前不会更新。例如，如果我在function1中以某种方式放置断点，并在bmp
上画一个十字，然后前进到picImage行上面，我执行它，图像仍然没有显示。我必须继续前进，直到GUI负责终于看到更新的图像 

However in visual studio I have noticed that while debugging, the image does not get updated until the operation is concluded and the GUI thread is in charge again. So for example if I put a breakpoint somehow in function1, and I draw a cross on the bmp and then advance to the line with picImage above, and I execute it, the image still don't show. I have to keep advancing until the GUI is in charge to finally see the updated image 

有没有办法，我可以看到更新的图像。换句话说，我可以调试图像（图片）吗？

Is there a way that I can see the updated image. In other words, can i debug with images (pictures)?

在这种情况下 - 例如，如果我需要检查，我的算法是否以正确的方式工作 -  我只是放了几行代码来输出一个或多个表格中的图片，如：

in such cases - eg, if I need to check, if my algorithm works the right way -  I just put some lines of code to output the picture in a form or so, like:

if(y % 100 == 0) //if inside a loop
{
    Form fff = new Form();
    fff.BackgroundImage = myBmpWork; //the bmp I work on
    fff.ShowDialog();
}
