Convert text file to image

Hi Rakrus,

I tried the same but i could'nt pass the stream value into Bitmap.. I got an error like "Parameter is not valid"

Error line:

BitMap image = new BitMap(stream); // Error: Parameter is not valid

Is there any other way.. If it's let me Know..

Hi ,

Can you try this

If suppose the text file is selectd by using input file control

   int len = Upload.PostedFile.ContentLength;
    byte[] pic = new byte[len];
    Upload.PostedFile.InputStream.Read (pic, 0, len);

    MemoryStream stream = new MemoryStream ();

   stream.Write (pic, 0, pic.Length);

        Bitmap bitmap = new Bitmap (stream);
        Response.ContentType = "image/gif";
        bitmap.Save (Response.OutputStream, ImageFormat.Gif);

 

Thanks

copy the content of text file and then pact it into a paint editor(ex. MSpaint)

and save as .bmp / .jpeg etc.
