Constructors
MetaImage()
Initialisiert eine neue Instanz des Aspose.Imaging.FileFormats.Emf.MetaImage.
public MetaImage()
Properties
Records
Sie erhalten oder setzen die Aufzeichnungen.
public virtual MetaObjectList Records { get; set; }
Eigentumswert
Examples
Dieses Beispiel zeigt, wie man ein WMF-Bild aus einem Datei laden und alle seine Aufzeichnungen auflistet.
string dir = "c:\\temp\\";
// Using Aspose.Imaging.Image.Load is a unified way to load all types of images including WMF.
using (Aspose.Imaging.FileFormats.Wmf.WmfImage wmfImage = (Aspose.Imaging.FileFormats.Wmf.WmfImage)Aspose.Imaging.Image.Load(dir + "test.wmf"))
{
// Cache data to load all records.
wmfImage.CacheData();
System.Console.WriteLine("The total number of records: {0}", wmfImage.Records.Count);
// The key is a record type, the value is number of records of that type in the WMF image.
System.Collections.Generic.Dictionary<system.type, int=""> types =

// Gather statistics
foreach (Aspose.Imaging.FileFormats.Wmf.Objects.WmfObject obj in wmfImage.Records)
{
