Graphics::EnumerateMetafile Method (Metafile^, Point, Rectangle, GraphicsUnit, Graphics::EnumerateMetafileProc^, IntPtr)
Sends the records in a selected rectangle from a Metafile, one at a time, to a callback method for display at a specified point.
Assembly: System.Drawing (in System.Drawing.dll)
public: void EnumerateMetafile( Metafile^ metafile, Point destPoint, Rectangle srcRect, GraphicsUnit srcUnit, Graphics::EnumerateMetafileProc^ callback, IntPtr callbackData )
Parameters
- metafile
-
Type:
System.Drawing.Imaging::Metafile^
Metafile to enumerate.
- destPoint
-
Type:
System.Drawing::Point
Point structure that specifies the location of the upper-left corner of the drawn metafile.
- srcRect
-
Type:
System.Drawing::Rectangle
Rectangle structure that specifies the portion of the metafile, relative to its upper-left corner, to draw.
- srcUnit
-
Type:
System.Drawing::GraphicsUnit
Member of the GraphicsUnit enumeration that specifies the unit of measure used to determine the portion of the metafile that the rectangle specified by the srcRect parameter contains.
- 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 callsPlayRecord, 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^).
