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

 

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

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

Public Sub EnumerateMetafile (
	metafile As Metafile,
	destRect As RectangleF,
	srcRect As RectangleF,
	srcUnit As GraphicsUnit,
	callback As Graphics.EnumerateMetafileProc,
	callbackData As IntPtr
)

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.

callbackData
Type: System.IntPtr

Internal pointer that is required, but ignored. You can pass Zero for this parameter.

This method enumerates the records contained in the specified metafile. Each record is individually sent to a callback method specified by thecallback 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.
