Class EmfSelectObject
Namespace: Aspose.Imaging.FileFormats.Emf.Emf.Records
Assembly: Aspose.Imaging.dll (25.4.0)
The EMR_SELECTOBJECT record adds a graphics object to the current metafile playback device context. The object is specified either by its index in the EMF Object Table(section 3.1.1.1) or by its value from the StockObject enumeration(section 2.1.31).

public EmfSelectObject()Examples
The following example shows how set the background color for EMF. It actually puts a rectangle of the background color before drawing all other objects.
string dir = "c:\\aspose.imaging\\issues\\net\\3280\\";
string inputFilePath = dir + "image1.emf";
string outputFilePath = dir + "ChangeBackground_" + "image1.emf";
using (Aspose.Imaging.FileFormats.Emf.MetaImage image = (Aspose.Imaging.FileFormats.Emf.MetaImage)Aspose.Imaging.Image.Load(inputFilePath))
{
AddBackgroundRectangleEmf((Aspose.Imaging.FileFormats.Emf.EmfImage)image, Aspose.Imaging.Color.Blue);
image.Save(outputFilePath);
}
/// <summary>
/// Helper method to change EMF background.

public static void AddBackgroundRectangleEmf(Aspose.Imaging.FileFormats.Emf.EmfImage image, Aspose.Imaging.Color color)
{
image.CacheData();
if (image.Records.Count < 1)
{
return;
}
//Set Rectangle
Aspose.Imaging.FileFormats.Emf.Emf.Records.EmfRectangle rectangle = new Aspose.Imaging.FileFormats.Emf.Emf.Records.EmfRectangle();
rectangle.Box = image.Header.EmfHeader.Bounds;
//Set Brush
Aspose.Imaging.FileFormats.Emf.Emf.Records.EmfCreateBrushIndirect brush = new Aspose.Imaging.FileFormats.Emf.Emf.Records.EmfCreateBrushIndirect();
brush.LogBrush = new Aspose.Imaging.FileFormats.Emf.Emf.Objects.EmfLogBrushEx();
brush.LogBrush.Argb32ColorRef = color.ToArgb();

brush.IhBrush = 1;
//Select brush
Aspose.Imaging.FileFormats.Emf.Emf.Records.EmfSelectObject selectObject = new Aspose.Imaging.FileFormats.Emf.Emf.Records.EmfSelectObject();
selectObject.ObjectHandle = 1;
//Remove brush
Aspose.Imaging.FileFormats.Emf.Emf.Records.EmfDeleteObject deleteObject = new Aspose.Imaging.FileFormats.Emf.Emf.Records.EmfDeleteObject();

//Add records
image.Records.Insert(1, brush);
image.Records.Insert(2, selectObject);

}Properties
ObjectHandle
Gets or sets 32-bit unsigned integer that specifies either the index of a graphics object in the EMF Object Table or the index of a stock object from the Aspose.Imaging.FileFormats.Emf.Emf.Consts.EmfStockObject enumeration.
public int ObjectHandle { get; set; }
