Graphics.EnumerateMetafile Method (Metafile, Rectangle, Graphics.EnumerateMetafileProc, IntPtr, ImageAttributes)

 

Sends the records of the specified 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,
	Rectangle destRect,
	Graphics.EnumerateMetafileProc callback,
	IntPtr callbackData,
	ImageAttributes imageAttr
)

Parameters

metafile
Type: System.Drawing.Imaging.Metafile

Metafile to enumerate.

destRect
Type: System.Drawing.Rectangle

Rectangle structure that specifies the location and size of the drawn metafile.

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.

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