Příklady

Následující příklad kódu ukazuje, jak zapisovat metadata na rastrový obrázek pomocí popisných vlastností BitmapMetadata třídy.

FileStream stream3 = new FileStream( "image2.tif", FileMode.Create );
BitmapMetadata myBitmapMetadata = new BitmapMetadata( "tiff" );
TiffBitmapEncoder encoder3 = new TiffBitmapEncoder();
myBitmapMetadata.ApplicationName = "Microsoft Digital Image Suite 10";
myBitmapMetadata.Author = new ReadOnlyCollection<string>( 
    new List<string>() { "Lori Kane" } );
myBitmapMetadata.CameraManufacturer = "Tailspin Toys";
myBitmapMetadata.CameraModel = "TT23";
myBitmapMetadata.Comment = "Nice Picture";

myBitmapMetadata.DateTaken = "5/23/2010";
myBitmapMetadata.Keywords = new ReadOnlyCollection<string>( 
    new List<string>() { "Lori", "Kane" } );
myBitmapMetadata.Rating = 5;
myBitmapMetadata.Subject = "Lori";
myBitmapMetadata.Title = "Lori's photo";

// Create a new frame that is identical to the one 
// from the original image, except for the new metadata.
