I have Two application one is desktop and other one is web application.
we are storing image in db using desktop application with c#.net/mysql (blob data type in mysql) as images is capture by signature device.
i want to show that image in web application but its not working. i am using
$im = imagecreatefromstring($data);
if ($im !== false) {
header('Content-Type: image/png');
imagepng($im);
imagedestroy($im);
}
else {
echo 'An error occurred.';
}
Warning: imagecreatefromstring(): Data is not in a recognized format in
This is how i am saving in DB @
Dim myimage As Image
Dim fileName As String = "c:\img.jpg"
myimage.Save(fileName, System.Drawing.Imaging.ImageFormat.Jpeg)
Dim imgBytes() As Byte = Nothing
Dim uFileInfo As New IO.FileInfo(fileName)
Dim uFileLength As Long = uFileInfo.Length
Dim uFstream As New FileStream(fileName, FileMode.Open, FileAccess.Read)
Dim uBinaryReader As New BinaryReader(uFstream)
imgBytes = uBinaryReader.ReadBytes(Convert.ToInt32(uFileLength))
Dim Cmd As New System.Data.Odbc.OdbcCommand("update tbl set Sign=? where ID='1', ConnectionString)
Dim param1 As System.Data.Odbc.OdbcParameter
param1 = New OdbcParameter("?", OdbcType.Binary)
param1.DbType = DbType.Binary
param1.Value = imgBytes
param1.Size = imgBytes.Length
Cmd.Parameters.Add(param1)
