Hi,

I am creating xps report dynamically using wpf. My approach was to use the

method provided by drawing context class to draw text, rectangle, line and etc,

but the "alignment" is not so correct. All my "alignment" is done using some complex

calculation. I Know that WPF is freeflowing can any one suggest the better approach,

so that I can use WPF full functionality and I can aviod the calculation.

I will send the some sample code:

C#

visual = new DrawingVisual();
drawingContext = visual.RenderOpen();

private void PrintHeader() {

      x = Sizes.Gutter;
      y = Sizes.Margin;
      Rect rect = new Rect(Sizes.Gutter,Sizes.Margin,Sizes.Width,Sizes.Header);
      drawingContext.DrawRectangle(color,Pens.Blueline,rect);
      Bitmap bitmap = Resources.Logo;
      BitmapSource imgSource = ConvertToBitmapSource(bitmap);
     drawingContext.DrawImage(imgSource, new Rect(Sizes.Gutter + 10, Sizes.Margin + 10, 150, 50));   

 DrawCentered(GetMetaText("Title").ToUpper(), Font.Header, Brushes.White, rect, FontSizes.Header);
      rect.Offset(0,20);
      DrawCentered(GetMetaText("Department"), Font.Body, Brushes.White, rect, FontSizes.Body);
      rect.Offset(0,10);
      DrawCentered(GetMetaText("Phone"), Font.Body, Brushes.White, rect, FontSizes.Body);

 Rect lineRect = new Rect(rect.Left,0,rect.Width,Sizes.Leading);
        lineRect.Y = rect.Bottom - (((float)value - bounds.MinY) * rect.Height / (bounds.Height));

}

  internal void DrawLeft(string text,Typeface font,Brush brush,Rect rect,int size) {
      rect.Inflate(-Sizes.Padding,-Sizes.Padding);
      drawingContext.DrawText(new FormattedText(text,CultureInfo.GetCultureInfo("en-us"),
                                                FlowDirection.LeftToRight,font,
                                                12,brush),new Point(rect.X,rect.Y));

    }

    internal void DrawCentered(string text,Typeface font,Brush brush,Rect rect,float size) {
      drawingContext.DrawText(new FormattedText(text,CultureInfo.GetCultureInfo("en-us"),
                                  FlowDirection.LeftToRight,font,
                                  size,brush),new Point(rect.X,rect.Y));

    }

    internal void DrawRight(string text,Typeface font,Brush brush,Rect rect,float size) {
      rect.Inflate(-Sizes.Padding,-Sizes.Padding);
      drawingContext.DrawText(new FormattedText(text,CultureInfo.GetCultureInfo("en-us"),
                                                FlowDirection.LeftToRight,font,
                                                size,brush),new Point(rect.Y - 20,rect.Y));
    }

I would use the FlowDocument. That way, you can produce your report in XAML.

<FlowDocumentReader>
    <FlowDocument
        Name="flowDocument"
        ColumnWidth="400" FontSize="14" FontFamily="Georgia">
        <Paragraph>
            <Grid>
                <Rectangle Fill="Red" Width="200" Height="100"/>
                <TextBlock Text="Hello World!" HorizontalAlignment="Center" VerticalAlignment="Center"/>
            </Grid>
        </Paragraph>
    </FlowDocument>
</FlowDocumentReader>

With some C# code to save it as XPS:

C#

public static void SaveAsXps(string path, FlowDocument document)
{
    using (var package = Package.Open(path, FileMode.Create))
    {
        using (var xpsDocument = new XpsDocument(package, System.IO.Packaging.CompressionOption.Maximum))
        {
            var xpsSerializationManager = new XpsSerializationManager(new XpsPackagingPolicy(xpsDocument), false);
            var documentPaginator = ((IDocumentPaginatorSource)document).DocumentPaginator;
            xpsSerializationManager.SaveAsXaml(documentPaginator);
        }
    }
}

And finally the call to this function:

C#

SaveAsXps("temp.xps", flowDocument);
