Graphics::EnumerateMetafile Method (Metafile, array<PointF>, RectangleF, GraphicsUnit, Graphics::EnumerateMetafileProc)

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

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

public:
void EnumerateMetafile(
	Metafile^ metafile, 
	array<PointF>^ destPoints, 
	RectangleF srcRect, 
	GraphicsUnit srcUnit, 
	Graphics::EnumerateMetafileProc^ callback
)

Parameters

metafile
Type: System.Drawing.Imaging::Metafile

Metafile to enumerate.

destPoints
Type: array<System.Drawing::PointF>

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

srcRect
Type: System.Drawing::RectangleF

RectangleF structures 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.

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 destPoints parameter specifies three points of a parallelogram. The three Point 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.
