ReaderWmfReadGeometry Method (Stream, GeometrySettings)
Reads metafile (emf or wmf) from fileName and returns System.Windows.Controls.Image with elements as Drawings (DrawingGeometry, EllipseGeometry, GlyphRunDrawing etc.).

Namespace: Ab2d
Assembly: Ab2d.ReaderWmf (in Ab2d.ReaderWmf.dll) Version: 7.1.5512.1040
Syntax
C#
Copy
public Image ReadGeometry(
	Stream stream,
	GeometrySettings settings
)

Parameters

stream
Type: System.IOStream
stream
settings
Type: Ab2d.Common.ReaderWmfGeometrySettings
GeometrySettings that defines how the geometry will be created

Return Value

Type: Image
Image
Remarks

Drawing objects do not derive from the FrameworkElement class and provide a lighter-weight implementation for rendering shapes, images, and text. Because of this Drawing objects on one side lack support for Layout System, input, and focus, but on the other side have much better performance and lower memory consumption.

Returned Drawing has much better performance as Shapes that are returned with Read method.

If better layout support, input, focus and other functionality is needed use Read method instead that returns elements as Shapes.

It is also possible to optimize the read Drawing objects with the GeometrySettings objects that is passed to the ReadGeometry method.

Examples
The following sample reads the mySample.wmf file into sampleImage:
Copy
Image sampleImage = myReader.ReadGeometry(@"c:\mySample.wmf");
The following sample shows how to read metafile from Application's Resource (mySample.emf file is included into the project under cliparts folder and its build action is set to Resource). The metafile is read into Drawing objects with full geometry optimization.
Copy
Image clipartFromResource;
Ab2d.Common.ReaderWmf.GeometrySettings settings;

// gets Drawing objects optimized for best performance
// NOTE: Because of heavy optimization it is possible that some anomalies appear on the image
settings = Ab2d.Common.ReaderWmf.GeometrySettings.FullOptimization;

Uri uri = new Uri("/cliparts/mySample.emf", UriKind.Relative);
using (Stream metafileStream = Application.GetResourceStream(uri).Stream)
{
    clipartFromResource = Ab2d.ReaderWmf.Instance.ReadGeometry(metafileStream, settings);
}
