| Exception | Condition |
|---|---|
| ArgumentException | The image format of this image does not support property items. |
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.
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.
Private Sub DemonstratePropertyItem(ByVal e As PaintEventArgs)
' Create two images.
Dim image1 As Image = Image.FromFile("c:\FakePhoto1.jpg")
Dim image2 As Image = Image.FromFile("c:\FakePhoto2.jpg")
' Get a PropertyItem from image1.
Dim propItem As PropertyItem = 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)
End Sub
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);
}
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 );
