public EmfCreateBrushIndirect()Examples
El siguiente ejemplo muestra cómo configurar el color de fondo para EMF. De hecho, pone un rectángulo del color de fondo antes de dibujar todos los demás objetos.
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.
/// </summary>
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();

//Add records
