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

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

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

public void EnumerateMetafile (
	Metafile metafile,
	PointF[] destPoints,
	RectangleF srcRect,
	GraphicsUnit unit,
	EnumerateMetafileProc callback,
	IntPtr callbackData,
	ImageAttributes imageAttr
)
public void EnumerateMetafile (
	Metafile metafile, 
	PointF[] destPoints, 
	RectangleF srcRect, 
	GraphicsUnit unit, 
	EnumerateMetafileProc callback, 
	IntPtr callbackData, 
	ImageAttributes imageAttr
)
public function EnumerateMetafile (
	metafile : Metafile, 
	destPoints : PointF[], 
	srcRect : RectangleF, 
	unit : GraphicsUnit,

Not applicable.

Parameters

metafile

Metafile to enumerate.

destPoints

Array of three PointF structures that define a parallelogram that determines the size and location 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.

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.

The destPoints parameter specifies three points of a parallelogram. The three PointF structures represent the upper-left, upper-right, and lower-left corners of the parallelogram. The fourth point is extrapolated from the first three to form a parallelogram. The drawn metafile is scaled and sheared to fit the parallelogram.

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.
