Image acquisition needs to call the camera on the line to take photos, online check the data, you need to refer to the following 3 DLLs.

Look at the running interface.

The interface is relatively low, mainly functional implementation.

private void Camera_load (object sender, EventArgs e) {this.btnSave.Enabled = false; try {bordersize = getbordersize (thi
s);

Save a photo to automatically overwrite the same name or add a watermark effect to the photo.

You can drag a rectangular box to choose a picture when you operate

The above is a small set of C # to introduce the implementation of mobile phone photos and save watermark Photos, I hope to help everyone, if you have any questions please give me a message, small series will promptly reply to everyone.
