Blob byte array in XML to Image
- by Rayvr
Hi,
I am getting a XML File to generate a preview, in a format like this:
<PARAM>
<LABEL>Preview 16x16</LABEL>
<ID>{03F5C6D3-ABCD-4889-B3AA-C3524C62FA1C}</ID>
<LAYER>-1</LAYER>
<VALUE>
<BLOB>

</BLOB>
</VALUE>
</PARAM>
I need to convert the <BLOB> section into an Image. I access the Element Value like this:
string clean = valueC.ElementAt(0).Value.Replace("\t", string.Empty).Replace("\n", string.Empty);
I've tried to read it into a MemoryStream and convert to Image:
MemoryStream ms = new MemoryStream(blob, 0, blob.Length);
ms.Write(blob, 0, blob.Length);
Image i = Image.FromStream(ms);
In this way I get "Parameter not valid exception" at getting the Image.
I've also tried to save it directly into a File:
using (FileStream fs = new FileStream(label + ".jpg", FileMode.Create))
{
fs.Write(blob, 0, blob.Length);
}
But when I try to open the generated file, displays a message about damage in it.
I know that encoding is important, I've already tried ASCII, UTF-8, UTF-7 and this:
BinaryFormatter bf = new BinaryFormatter();
MemoryStream ms = new MemoryStream();
bf.Serialize(ms, clean);
ms.Seek(0, 0);
byte[] blob = ms.ToArray();
I dont know what else to do. I'll appreciate if somebody can help me.
Thanks
