Image.SetPropertyItem(PropertyItem) Method

Definition

Namespace:

System.Drawing

Assembly:

System.Drawing.Common.dll

Source:

Image.cs

Stores a property item (piece of metadata) in this Image.

C#

public void SetPropertyItem(System.Drawing.Imaging.PropertyItem propitem);

Parameters

propitem

PropertyItem

The PropertyItem to be stored.

Exceptions

ArgumentException

The image format of this image does not support property items.

Examples

The following code example demonstrates how to use the GetPropertyItem and SetPropertyItem methods. This example is designed to be used with Windows Forms. To run this example, paste it into a form, and handle the form's Paint event by calling the DemonstratePropertyItem method, passing e as PaintEventArgs.

C#

private void DemonstratePropertyItem(PaintEventArgs e)
{

    // Create two images.
    Image image1 = Image.FromFile("c:\\FakePhoto1.jpg");
    Image image2 = Image.FromFile("c:\\FakePhoto2.jpg");

    // Get a PropertyItem from image1.
    PropertyItem propItem = image1.GetPropertyItem(20624);

    // Change the ID of the PropertyItem.
    propItem.Id = 20625;

    // Set the PropertyItem for image2.
    image2.SetPropertyItem(propItem);

    // Draw the image.
    e.Graphics.DrawImage(image2, 20.0F, 20.0F);
}

Remarks

If the image format does not support property items, this method throws ArgumentException with the message "Property not supported." If the image format supports property items but does not support the particular property you are attempting to set, this method ignores the attempt but does not throw an exception.

It is difficult to set property items, because the PropertyItem class has no public constructors. One way to work around this restriction is to obtain a PropertyItem by retrieving the PropertyItems property value or calling the GetPropertyItem method of an Image that already has property items. Then you can set the fields of the PropertyItem and pass it to SetPropertyItem.
