MetaImage()
Bắt đầu một ví dụ mới của Aspose.Imaging.FileFormats.Emf.MetaImage.
public MetaImage()Properties
Records
Nhận hoặc đặt các hồ sơ.
public virtual MetaObjectList Records { get; set; }Giá trị bất động sản
Examples
Ví dụ này cho thấy cách tải một hình ảnh WMF từ một tệp và liệt kê tất cả các bản ghi của nó.
string dir = "c:\\temp\\";
// Using Aspose.Imaging.Image.Load is a unified way to load all types of images including 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.Console.WriteLine("{0}:{1}{2}", entry.Key.Name, alignmentGap, entry.Value);
