Graphics::EnumerateMetafile Method (Metafile^, RectangleF, RectangleF, GraphicsUnit, Graphics::EnumerateMetafileProc^)
Sends the records of a selected rectangle from a Metafile, one at a time, to a callback method for display in a specified rectangle.
Assembly: System.Drawing (in System.Drawing.dll)
public: void EnumerateMetafile( Metafile^ metafile, RectangleF destRect, RectangleF srcRect, GraphicsUnit srcUnit, Graphics::EnumerateMetafileProc^ callback )
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.
- srcRect
-
Type:
System.Drawing::RectangleF
RectangleF 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.
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.
Any drawing that takes place outside of the rectangle specified by the srcRect parameter is ignored.
For a code example, see EnumerateMetafile(Metafile^, Point, Graphics::EnumerateMetafileProc^).
