Converting a byte array to PNG/JPG [closed]

Question

I am currently working on an application that requires high-performance conversion of an unpadded byte array to either a PNG or JPEG. The image format doesn't matter, just as long as it's fast.

I have tried the .NET libraries and the performance is very bad. Can anyone recommend a good freeware library for this?

EDIT: the byte[] is an 8bit grayscale bitmap

You should be able to do something like this:

using System.Drawing.Imaging; using System.Drawing; using System.IO;  byte[] bitmap = GetYourImage();  using(Image image = Image.FromStream(new MemoryStream(bitmap))) {     image.Save("output.jpg", ImageFormat.Jpeg);  // Or Png } 

Look here for more info.

Hopefully this helps.
