I just made a full night of watermark for an image.

Winform does not touch it for a long time. It feels unfamiliar. It took so long to get this little thing from last night till now. I still don't know much about GDI + in. net. The synthesis of a transparent image really gave me a headache.

Put a demo first. I hope someone can take a look and give some comments. I am very interested in improving this thing.
