You can use Bitmap.Save method. Something like this. curBitmap .Save("c:\\myfile.gif", System.Drawing.Imaging.ImageFormat.Gif);

this is great!:) but could i ask a question: please how do you save the output image to your local disk? i will greatly appreciate the help. thanks:)

Yes it is possible. Since you already have a Graphics object, every thing is being drawn on this Graphics and Bitmap object was created later. You can use Graphics and Bitmap and use Bitmap to save a file.

Look at Bitmap.Save method. Search this site or Google or MSDN.

Thanks for that dude.. great job
Question : Is it possible to combine various transformations by multiplying their corresponding matrices, and apply 
the resulting matrix to the image ?
