The only thing left to do now is drag a new button on the windows form and call it 'Meta Data' double click it to create 'MetaData_Click' in form1.cs and add call the meta method meta() This would give us the model of the camera and the date and time that the picture was taken. String DT = encodings.GetString(propItems.Value) String model = encodings.GetString(propItems.Value) which will be '0x010F' this is the manufacturer name. PropItems.Value - this gives us the Value of second item in the propItems array. this will give us, in plain English, the data we need. Here we are using the ASCIIEncoding object to translate the array of Values mentioned earlier in the tutorial. String make = encodings.GetString(propItems.Value)

Next we need to add the following code outside the foreach loop:ĪSCIIEncoding encodings = new ASCIIEncoding() 0x9003 - this will give us the data and time the picture was taken.0x0110 - and this will give us the model of the camera.0x010F - this hex ID will give us the camera manufacturer.In this tutorial we are only interested in the following three: The item.Id property should return a whole list of hex numbers. The int count will +1 every time is goes through the foreach loop giving us the number of attributes in the metadata. The listbox will be populated with the metadata. Next we need to drag a listbox onto our windows form and in form1.cs add in a counter and aįoreach loop to retrieve all information. We use the PropertItem array to store all property items from the image as mentioned in the intro to this tutorial. PropertyItem propItems = image.PropertyItems Īs you can see the Bitmap object encapsulates the image which was loaded up in step one. In this method we need to add the following objects:īitmap image = new Bitmap(data.FileName) In this step we are going to create a new method called public void meta() This always restores the directory to my pictures This will give only one option when choosing file types Sets the default start point when looking for an image file. Is the title that appears on top of the file dialog window. These properties are all very straight forward but ill explain them just in case. Private void Load_Click(object sender, EventArgs e)ĭata.InitialDirectory = 'JPG files (*.jpg*)|*.jpg' OpenFileDialog data = new OpenFileDialog() Obejct with the following properties as shown below: Then we drag a PictureBox onto the form.ĭouble click the button to create the 'Load_Click' in form1.cs. The first thing we need to do is load up visual studio, drag a button onto a windows form and call it 'Load'. The only properties we will be taking notice of is ID and Value properties. Type - this gives us the datatype of the values in the array.Len - this tells us the length (in bytes) of the value property.Value - this is an array of values, the format is decided by the type property.ID - the ID property can contain information about the camera used to take the photo.It does this using the following four properties: Namespace for this tutorial, the reason for this is because it contains the ' PropertyItem' object which enables us to read the metadata from an image file. features like the model of a camera and the date and time the photo was taken. Ok so what is metadata?, if you already know you can skip this paragraph, if not, metadata is hidden data which can be read to determine certain features of the image. Ok so lets get started, in this tutorial I will be showing you how you can extract metadata from an image file.
