Error" Parameter is not valid " while converting Bytes into Image

Question

I am converting bytes into an image but I get an error

Parameter is not valid

I am pasting my code. Kindly check the code and suggested that was I am doing right or wrong.

Image arr1 = byteArrayToImage(Bytess);

This is the function.

public static Image byteArrayToImage(byte[] byteArrayIn)
{
        if (null == byteArrayIn || byteArrayIn.Length == 0)
            return null;

        MemoryStream ms = new MemoryStream(byteArrayIn);
        try
          {
            Process currentProcess1 = Process.GetCurrentProcess();
            Image returnImage = Image.FromStream(ms);
            return returnImage;
          }
        catch (Exception ex)
          {
            MessageBox.Show(ex.Message);
          }
    }

I applied many techniques and solutions but it did not work for me

Your answer would be appreciated.

Thanks

Solution 1

try this

public Image byteArrayToImage(byte[] byteArrayIn)
{
    System.Drawing.ImageConverter converter = new System.Drawing.ImageConverter();
    Image img = (Image)converter.ConvertFrom(byteArrayIn);

    return img;
}

Solution 2

After trying many things I found a way which has a little bit more control. In this example you can specify the pixel format and copy the bytes to a Bitmap.

byte[] buffer = GetImageBytes();
var bitmap = new Bitmap(width, height, PixelFormat.Format32bppArgb);
var bitmap_data = bitmap.LockBits(new Rectangle(0, 0, bitmap.Width, bitmap.Height), ImageLockMode.WriteOnly, PixelFormat.Format32bppArgb);
Marshal.Copy(buffer, 0, bitmap_data.Scan0, buffer.Length);
bitmap.UnlockBits(bitmap_data);
var result = bitmap as Image;

No , It doesn`t Work . my bytes are 1120135

[sangram parmar]

like this byte[] array = { 68, 111, 116, 32, 78, 101, 116, 32, 80, 101, 114, 108, 115 };

Actually my byte are generated from dialog Box , so how can i write here , first i select image from dialog box and than pass that image bytes into this method

Hi Umair, I think your byte[] value is not in correct format. do one think, for checking take one image convert to byte[] after that pass this byte value to above coding. If it's converting correct image mean's the problem in your byte value. Let's know..

having the same issue when downloading an image from S3. However, when using the file before uploading (after submited using a form) it works without an issue. Still can't figure this out

Omg. This saved me. I had already spent a couple hours with the old parameter is not valid exception. I was using the Image.FromStream method: stackoverflow.com/questions/457370/…
