Graphics.EnumerateMetafile Method (Metafile, Point[], Graphics.EnumerateMetafileProc, IntPtr)
Sends the records in the specified Metafile, one at a time, to a callback method for display in a specified parallelogram.
Assembly: System.Drawing (in System.Drawing.dll)
public void EnumerateMetafile( Metafile metafile, Point[] destPoints, Graphics.EnumerateMetafileProc callback, IntPtr callbackData )
Parameters
- metafile
-
Type:
System.Drawing.Imaging.Metafile
Metafile to enumerate.
- destPoints
-
Type:
System.Drawing.Point[]
Array of three Point structures that define a parallelogram that determines the size and location of the drawn metafile.
- callback
-
Type:
System.Drawing.Graphics.EnumerateMetafileProc
Graphics.EnumerateMetafileProc delegate that specifies the method to which the metafile records are sent.
- callbackData
-
Type:
System.IntPtr
Internal pointer that is required, but ignored. You can pass Zero for this parameter.
This method enumerates the records contained in the specified metafile. Each record is individually sent to a callback method specified by the callback parameter. Typically, the callback method calls the PlayRecord method to "play back", or draw, the record.
If the callback method calls PlayRecord, it must do so by calling the PlayRecord method of the specific Metafile that is being enumerated.
For a code example, see EnumerateMetafile(Metafile, Point, Graphics.EnumerateMetafileProc).
