将字节数组转换为图像/参数在c#中无效错误

Question

我想将字节数组更改为图像文件。 但我收到错误

参数无效。

输入数据

type : byte[]
byte array length : 996
byte order : little endian

假设输入数据没有错误。

我尝试过的：

图像转换器、内存流

 MemoryStream ms = new MemoryStream(bytes);
 System.Drawing.Image returnImage = System.Drawing.Image.FromStream(ms,false,false);

我需要帮助......

Convert.ToBase64String(bytes) 的结果；

Answer 1

将图像表示为字节数组有两种基本方法：

图像文件

这包含以某种方式编码的数据。文件通常以“文件签名”为前缀。例如，Jpeg 应以 FF D8 FF 开头。

原始数据

这意味着图像包含原始像素值。不幸的是，这还不够。您还至少需要知道：

图像宽度（一行像素数）

1. 像素格式
2. 图像步长（一行的字节数）
您可能能够猜测其中一些参数，例如步幅和宽度通常是相关的。

根据您的数据，我的猜测是它是原始像素值。您可以

猜测

该图像是方形 RGB 图像，创建一个位图并使用 LockBits 来访问像素缓冲区、复制数据并查看其外观。但您很可能需要花一些时间调整宽度/高度才能使其看起来正确。
