Sends the records in a selected rectangle from a Metafile, one at a time, to a callback method for display at a specified point using specified image attributes.

Namespace:   System.Drawing
Assembly:  System.Drawing (in System.Drawing.dll)

Public Sub EnumerateMetafile (
	metafile As Metafile,
	destPoint As Point,
	srcRect As Rectangle,
	unit As GraphicsUnit,
	callback As Graphics.EnumerateMetafileProc,
	callbackData As IntPtr,
	imageAttr As ImageAttributes
)

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.

unit
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.

imageAttr
Type: System.Drawing.Imaging.ImageAttributes

ImageAttributes that specifies image attribute information for the drawn image.

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.
