Graphics.EnumerateMetafile Method (Metafile, PointF, RectangleF, GraphicsUnit, Graphics.EnumerateMetafileProc, IntPtr, ImageAttributes)
Assembly: System.Drawing (in system.drawing.dll)
public: void EnumerateMetafile ( Metafile^ metafile, PointF destPoint, RectangleF srcRect, GraphicsUnit unit, EnumerateMetafileProc^ callback, IntPtr callbackData, ImageAttributes^ imageAttr )
public void EnumerateMetafile ( Metafile metafile, PointF destPoint, RectangleF srcRect, GraphicsUnit unit, EnumerateMetafileProc callback, IntPtr callbackData, ImageAttributes imageAttr )
public function EnumerateMetafile ( metafile : Metafile, destPoint : PointF, srcRect : RectangleF, unit : GraphicsUnit, callback : EnumerateMetafileProc, callbackData : IntPtr, imageAttr : ImageAttributes )
Not applicable.
Parameters
- metafile
Metafile to enumerate.
- destPoint
PointF structure that specifies the location of the upper-left corner of the drawn metafile.
- srcRect
RectangleF structure that specifies the portion of the metafile, relative to its upper-left corner, to draw.
- unit
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
Graphics.EnumerateMetafileProc delegate that specifies the method to which the metafile records are sent.
- callbackData
Internal pointer that is required, but ignored. You can pass Zero for this parameter.
- imageAttr
ImageAttributes that specifies image attribute information for the drawn image.
Return Value
This method does not return a value.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.
Any drawing that takes place outside of the rectangle specified by the srcRect parameter is ignored.
The image attributes specified by the imageAttr parameter replace those specified when the metafile was written.
