public EmfCreateBrushIndirect()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);
}

}
//Set Rectangle
Aspose.Imaging.FileFormats.Emf.Emf.Records.EmfRectangle rectangle = new Aspose.Imaging.FileFormats.Emf.Emf.Records.EmfRectangle();

}Properties
IhBrush
Gets or sets A 32-bit unsigned integer that specifies the index of the logical brush object in the EMF Object Table (section 3.1.1.1). This index MUST be saved so that this object can be reused or modified.
public int IhBrush { get; set; }Property Value
LogBrush
Gets or sets A LogBrushEx object (section 2.2.12) that specifies the style, color, and pattern of the logical brush. The BrushStyle field in this object MUST be BS_SOLID, BS_HATCHED, or BS_NULL.
public EmfLogBrushEx LogBrush { get; set; }
