Esempi

L’esempio seguente mostra come impostare il colore di sfondo per WMF. In realtà disegna un rettangolo del colore di sfondo prima di disegnare tutti gli altri oggetti.

[C#]

string dir = "c:\\aspose.imaging\\issues\\net\\3280\\";
string inputFilePath = dir + "image2.wmf";
string outputFilePath = dir + "ChangeBackground_" + "image2.wmf";

using (Aspose.Imaging.FileFormats.Emf.MetaImage image = (Aspose.Imaging.FileFormats.Emf.MetaImage)Aspose.Imaging.Image.Load(inputFilePath))
{
    AddBackgroundRectangleWmf((Aspose.Imaging.FileFormats.Wmf.WmfImage)image, Aspose.Imaging.Color.Blue);
    image.Save(outputFilePath);
}

/// <summary>
/// Metodo di supporto per cambiare lo sfondo WMF. 
/// </summary>
public static void AddBackgroundRectangleWmf(Aspose.Imaging.FileFormats.Wmf.WmfImage image, Aspose.Imaging.Color color)
{
    image.CacheData();
    if (image.Records.Count < 1)
    {
        return;
    }

    //Imposta rettangolo
    Aspose.Imaging.FileFormats.Wmf.Objects.WmfRectangle rectangle = new Aspose.Imaging.FileFormats.Wmf.Objects.WmfRectangle();
    rectangle.Rectangle = image.FrameBounds;

    //Imposta pennello
    Aspose.Imaging.FileFormats.Wmf.Objects.WmfCreateBrushInDirect brush = new Aspose.Imaging.FileFormats.Wmf.Objects.WmfCreateBrushInDirect();
    brush.LogBrush = new Aspose.Imaging.FileFormats.Emf.Emf.Objects.EmfLogBrushEx();
    brush.LogBrush.Argb32ColorRef = color.ToArgb();

    //Seleziona pennello
    Aspose.Imaging.FileFormats.Wmf.Objects.WmfSelectObject selectObject = new Aspose.Imaging.FileFormats.Wmf.Objects.WmfSelectObject(brush);

    //Rimuovi il pennello
    Aspose.Imaging.FileFormats.Wmf.Objects.WmfDeleteObject deleteObject = new Aspose.Imaging.FileFormats.Wmf.Objects.WmfDeleteObject(brush);

    //Aggiungi record
    image.Records.Insert(0, brush);
    image.Records.Insert(1, selectObject);
    image.Records.Insert(2, rectangle);
    image.Records.Insert(3, deleteObject);
}
