First of all, forget PictureBox, if you want to manipulate the image in this or another way. It's possible, but not helpful. Use Image, not PictureBox.
Now, doing what you need is just some work to be done, it does not require some expert advice.
If you show what have you tried so far, explain the particular problem you are facing, we will gladly help you.

It looks like your questions are circulating about finding some existing code and using it. I don't see where you are trying to write anything. This would be off-topic for this forum unless you do.

He might not know how to go further with his project because he does not have the required knowledge...

Anyway he hasn't said which technology he's using... If he's using Windows Forms, I think PictureBox is the only way to display the image. If he's using WPF then Image is the control to be chosen.

Your statement about PictureBox is totally wrong. "Only way"? Rather, it is not a reasonable way at all, considering the fact the graphics should be modified (by showing those cropping lines OP really needs). PictureBox absolutely redundant and can only complicate things. Apparently, you have no clue how to reasonably render graphics in Forms, which would be fine. You can ask your questions, do your study, and so on. But it's really bad to try to confuse the beginners. They are already well confused by the fact this control is just there, so many beginners try to misuse it.

I looked at one of my old projects and... it seems you're right: I've used a Panel to display the image.

I'm sorry for my mistake, anyway, my aim was not to confuse the beginners.

Great. Panel could do, or many other things, basically, it could be any control derived from System.Windows.Forms.Control, a custom control.
No problem; I really appreciate your note.

Hi,

If you are working with Windows Forms, you can use GDI+ to crop images.
http://msdn.microsoft.com/en-us/library/e06tc8a5%28v=vs.110%29.aspx[^]

This is the search page of codeproject for query GDI+ with tags C# and beginner...

http://www.codeproject.com/search.aspx?q=gdi%2b+tag%3a%28c%23+and+Beginner%29&doctypeid=1%3b2%3b3%3b13%3b14[^]

and an article to start (Unfortunately, this is in C++)
Starting with GDI+[^]

Hope this helps...

Please see my comments to the question, on PictureBox. Even your own links clearly show that it should not be used. Should I understand it the way you don't understand what you reference by yourself? Please understand, I'm not trying to bug you with that. After all, it would be fine, you can give an advice without full understanding, you can always get to it later. I just want to advise: if you get into some arguments, learn the topic better.
