Sends the records of the specified Metafile, one at a time, to a callback method for display in a specified rectangle.
Assembly: System.Drawing (in System.Drawing.dll)
Public Sub EnumerateMetafile ( metafile As Metafile, destRect As RectangleF, callback As Graphics.EnumerateMetafileProc, callbackData As IntPtr )
Parameters
- metafile
-
Type:
System.Drawing.Imaging.Metafile
Metafile to enumerate.
- destRect
-
Type:
System.Drawing.RectangleF
RectangleF structure that specifies the location and size 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).
