Sorry because I couldn`t replay faster... I really apreciate your help . That link was helpfull but I have decided to copy one element at a time using a for loop.

Thhank you for your help

My goal is to make my own jpeg coder(a simple version of it). I`ve done all my codeing for the jpeg and now I want to make a function witch when I click in a specifict point of my image to take a block of 8 by 8 pixels and display it in another picture box but zoomed 10 times.

Sorry because I couldn`t replay faster but I had some problems and I didn`t had the chance to open my pc and go online.

Thank you for your replay.

Thank you

Thank you very much for your replay

Yes You are right . Probabliy because my english is not that good , or because I don`t have experience in this area I am contradicting myself.

I want to start with motion detection in a live stream and you were saying that is not that hard. Please can you give me some directions .

Thank you for your replay. I know that is not easy to do this , but I`ve already implemented the idea with hashtables and is working (I mean I can give a set of instruction and convert it in machine language only if the code is corect).

You`re ideea "I would start this from the other end" is interesting And I will try it .

I don`t know if i can attach an image , but if I can I will attach one with my arhitecture just to make an ideea.

Thank you for your replay . I`ve managed to solve my problem with Mark Nischalkes solution . Your links were very helpfull and I will use that information for the following steps of my project.
Next I want to zoom the selected square 10 times and store it in another pictureBox.

One more time Thank You

I am so stupid . Thank you very much for your replay . The exception was odd this is why I was confused .
One more time Thank you very much.

This solution works for me . it is grate , but i still have a problem.

<pre lang="c#">
try
{
Bitmap img = new Bitmap(imgIncarcata.Image);

Bitmap cropped = img.Clone(new Rectangle(coorX, coorY, 80, 80), imgIncarcata.Image.PixelFormat);

pbBlocOrig.Image = cropped;
}
catch (OutOfMemoryException oome)
{
MessageBox.Show(oome.ToString());
}
</pre>
Ok. Now when I click in some areas of the picture it works perfectly(top left corner) , but when I try to click on the right down corner it throws an exception :
System.OutOfMemoryException: Out of memory.
at System.Drawing.Bitmap.Clone(Rectangle rect, PixelFormat format)
at JpgProject.lblE.imgIncarcata_MouseClick(Object sender, MouseEventArgs e)

Thank you for your replay .
My goal is to edit the onClick event . My source img is a 256/256 bmp and what I want to do is : when I click with the mouse on a random point: for exp x=30, y=67 I want to be able to take all that 8 by 8 square of pixels where this point is placed.

Thank you very much for your quick answer . This was very helpful for me .
I really apreciate it
