Crop Image in C#

Nihal Ahmed

Hi,

I am working on image processing. I want to crop the image. I have written code like/*********

Bitmap bmp = image as Bitmap;

// Check if it is a bitmap:

if (bmp == null)

throw new ArgumentException(" image in null");

// Crop the image:

Bitmap cropBmp = bmp.Clone(selection, bmp.PixelFormat);

// Release the resources:

image.Dispose();

bmp.Dispose();

return cropBmp;

***********/

when i am run cropping, Its give the error : Out of Memory..Please help me.

Out of memory in C# imaging, is usually sign of wrong rect or point - a bit of red herring. I bet start has negative X or Y when error happens or the Size.Hight + Y or Size.Width + X is bigger than Hight or width of the image.

Copied directly from other posts, hope it can help you solve your image crop issue.

Bitmap cropping sometimes uses a lot of free memory because it needs the pixel data to be allocated for the original bitmap and an additional copy that gets the new image after cropping.
If your application handles huge images, consider using a 64-bit computer with lots of free RAM, and explicitly build your application as 64-bit (not x86). This allows it to handle much more memory than the limit for 32-bit processes (about 2 to 4 GB memory).
If your imaging needs go beyond simple cropping and you need more advanced features, you could consider using a professional imaging toolkit such as Leadtools.

You'll get an 'out of memory' exception if the 'selection' Rectangle is outside the bounds of the Bitmap.

So could that be the case here?
