Decoding base64 to generate png image

[Rajiya]

Hi, I am getting base64 text and i want to generate a png image from it. Can anyone please suggest me a good encoder or decode for the same. If anyone knows how to go about with yhis then plz help. The coding for the application is done using VB(using COM) and ASP. So any encoder or decoder making use of VB will be more useful. Plz provide me the details of the links if any. Regards, Shiney Shney

Hi, does the base64-text contains the bytes of a png? If yes, then just convert the string with the Convert.FromBase64String into a byte-array, put these into a memorystream and load the image using the Image.FromStream() where you pass the memorystream. Does this help you? Regards Sebastian

It's not a bug, it's a feature! Check out my CodeProject article Permission-by-aspect. Me in Softwareland.

Could you be so kind to describe exactly what you want to do? As I see it, the posted answers should enable you to write your own tool (not more than 10 loc).

I don't know any. But you can create it in some hours for yourself.
