Load Bitmap obj from System.Drawing.Image

Question

User1119954915 posted

Hi... I am trying to pass into a function a System.Drawing.Image object, and in that function, create a new Bitmap object to maipulate with text and watermarking

Problem is I cannot figure out how to go from Drawing.Image to a Stream.....  the image is not saved to the file system yet, so i cannot say:

bmp.FromFile

i have a feeling the ".FromStream" method is what i am after since the Image being passed in is from memory, but i cannot get the conversion right....

System.Drawing.Image is an abstract base class that provides functionality for the System.Drawing.Bitmap,  Most of the properties and method of Bitmap object are inherited from Image you might be able to perform same things to Image.

for example for Drawing text on Image

Graphics g = Graphics.FromImage(yourImageObj);

g.DrawString("test", new Font("Verdana", 2.00), Brushes.Black, new Point(10, 10)) ;

Or If you need your own copy of image out of original then.

Bitmap myCopyofImage = new Bitmap(yourImageObj);
