转换一个字节数组PNG / JPG [英] Converting a byte array to PNG/JPG

问题描述

我目前工作的，需要一个护垫字节数组的高性能转换到一个PNG或JPEG的应用程序。图像格式并不重要，只要你将它的快。

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.

我已经试过了.NET库和性能是非常糟糕的。任何人都可以推荐一个好免费软件库呢？

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

编辑：字节[]是一个8位灰度位图

the byte[] is an 8bit grayscale bitmap

推荐答案

您应该能够做这样的事：

You should be able to do something like this:

byte[] bitmap = GetYourImage();

using(Image image = Image.FromStream(new MemoryStream(bitmap)))
{
    image.Save("output.jpg", ImageFormat.Jpeg);  // Or Png
}

希望这有助于。
