This is not working properly.
is there any another code for cropping.

Jesus, check out fjcore (http://code.google.com/p/fjcore/). It’s an open source library that I’ve used before to encode a writeablebitmap to a jpg or png. You could then send those resulting bytes to your server.

Great code!

How could I save this writtable bitmap to a physical file in the server?

Thanks!

I’ve used the crop function code and its works perfectly fine.

Now, I would like to have a cut function which is similar to the select and cut function we have in mspaint.

i.e. when I crop any section from an image, that cropped section should be removed from the source image.

Just another comment:
This doesn’t work if the domain you are getting it from doesn’t allow it. It will only work on images from your own domain, or domains that are configured to allow this.
The version John gave the link to will work on every image.
Surprisingly there aren’t many info on this on the web.

John, thanks for the link! Interesting approach using the clip property and forcing that result to a writable bitmap. I wonder how the two options compare performance wise.

Just a general note to other readers about the clip property:
Cropping an image via the clip property does have the same visual effect but there is one key difference, the entire image is still loaded in memory. This can help performance if you need to change your clipping region at runtime but it can hurt performance if you need to break a single image up into many smaller images.
