Copy some piece of bit map on another bit map

[SarahBenjamin]

How can I copy some part of bitmap1 to bitmap 2.

 

In other words either copy or cut it from one graph to another.

Thanks

Try using the DrawImageUnscaledAndClipped() method of the Graphics object. You will have to create a bitmap where the clipped region will be drawn to, and a rectangle that defines which region to clip. The sample code below can give you an idea of what you need to do:

Image img = Image.FromFile("D:\\Beach.jpg");

Bitmap bmp = new Bitmap(img.Width, img.Height);Rectangle clipRect = new Rectangle(45, 175, 300, 150);

Graphics g1 = Graphics.FromImage((Image)bmp);

g1.DrawImageUnscaledAndClipped(img, clipRect);

Thanks for the reply, but I want to get a small piece of a 1500 px bitmap and then paste that on another bitmap.

This statment will give me the whole bitmap

Bitmap bmp = new Bitmap(img.Width, img.Height);

How can I get a small portion of bit map.

 

Thanks

Since this question is not related to Chart FX but is a general GDI+ question, you may have better luck at one of the Microsoft or general .NET forums.

Sure, thanks Frank... I figured it out..
