Watermarking of Images

[Preetha]

Hi, Im a C# beginner... Ive been trying to develop a program in C# for the watermarking of Images... is there someone whos already developed this code, or something similar? Do reply if you have pl... thnx.

Can you clarify which type of watermarking you mean?

I know of a method of inserting data in to an image file which isnt displayed, which is referred to as watermarking, and I know of the technique of showing a semi-transparent image in a corner of an image, also known as watermarking.

The watermarking i need to implement involves inserting data into an image file which isnt displayed. Its essentially to create a digital rights management system for Images.
Any code/advice you can offer will be helpful. Thanks.

Sorry, I dont know anything about doing that. Someone else here might though.

I didnt even know you could embed information like that into images - only other media types (sounds, video, etc.). But a quick search turned up this link.

Its more of a spec than a how-to-do-it-in-.NET. But it may provide some help to get started.

Do a websearch for Stego written by Cypherella. Its designed as an encryption vehicle, but does basically what you want.

I have made a watermarking program in VB.net. Useing gdi.

Look in the downloads.

If you would like help I know a bit about the gdi+ which is the easyest way to put the watermarks on... I cant help with the actual code as I do vb and not c# but they are simaler enough so that we should be able to sort it out.
