Graphics.EnumerateMetafile Method (Metafile, RectangleF, RectangleF, GraphicsUnit, Graphics.EnumerateMetafileProc, IntPtr, ImageAttributes)

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

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

public void EnumerateMetafile(
	Metafile metafile,
	RectangleF destRect,
	RectangleF srcRect,
	GraphicsUnit unit,
	Graphics..::..EnumerateMetafileProc callback,
	IntPtr callbackData,
	ImageAttributes imageAttr
)

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.
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 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.

The image attributes specified by the imageAttr parameter replace those specified when the metafile was written.
