When you access/edit the following types of images we will get the error "a graphics object cannot be created from an image that has an indexed pixel format"
Solution for this problem:
The following code will fix the error.
// create Image Object using rear image byte
Image imag = Image.FromStream(new MemoryStream(imageR));
// Derive BitMap object using Image instance, so that you can avoid the issue
//"a graphics object cannot be created from an image that has an indexed pixel format"
Bitmap img = new Bitmap(new Bitmap( imag ));
