FloatingBlockVerticalPosition.RelativeFrom Problem when exporting to PDF and set to VerticalRelativeFrom.Page

[Mi]

Hi!

I'm not sure if it is bug, or I'm doing something wrong.

I have a RadDocument-object. When I try to add a picture in the back und export it to a PDF the property RelativeFrom of VerticalPosition doesn't work as expected when it is set to VerticalRelativeFrom.Page. 

private void Pic2PDF()
{
    var doc = new Telerik.Windows.Documents.Model.RadDocument();
    var stream = new FileStream("C:\\temp\\test.pdf", FileMode.Create);
    var pdfExp = new Telerik.Windows.Documents.FormatProviders.Pdf.PdfFormatProvider();
    var pic = new FileStream("C:\\temp\\picture.jpg", FileMode.Open);

    var image = new Telerik.Windows.Documents.Model.FloatingImageBlock(pic, new Size(150, 150), "jpg");
    image.AllowOverlap = true;
    image.WrappingStyle = Telerik.Windows.Documents.Model.WrappingStyle.BehindText;
    image.HorizontalPosition = new Telerik.Windows.Documents.Model.FloatingBlockHorizontalPosition(Telerik.Windows.Documents.Model.FloatingBlocks.HorizontalRelativeFrom.Page, 250);
    image.VerticalPosition = new Telerik.Windows.Documents.Model.FloatingBlockVerticalPosition(Telerik.Windows.Documents.Model.FloatingBlocks.VerticalRelativeFrom.Page, 250);
    // if I uncomment the next line it works
    //image.VerticalPosition.RelativeFrom = Telerik.Windows.Documents.Model.FloatingBlocks.VerticalRelativeFrom.Paragraph;

    doc.InsertInline(image);

    pdfExp.Export(doc, stream);

}

Hi Mike,

The problem is that the default layout mode of RadDocument is Flow. In flow layout mode, there are no pages, that is why this option does not work.

What you can do in order to make it work is to set the layout mode of the document to Paged before the export:

var doc = new Telerik.Windows.Documents.Model.RadDocument();



doc.LayoutMode = DocumentLayoutMode.Paged;



var stream = new FileStream("C:\\temp\\test.pdf", FileMode.Create);

var pdfExp = new Telerik.Windows.Documents.FormatProviders.Pdf.PdfFormatProvider();

var pic = new FileStream("C:\\temp\\picture.jpg", FileMode.Open);

 

var image = new Telerik.Windows.Documents.Model.FloatingImageBlock(pic, new Size(150, 150), "jpg");

image.AllowOverlap = true;

image.WrappingStyle = Telerik.Windows.Documents.Model.WrappingStyle.BehindText;

image.HorizontalPosition = new Telerik.Windows.Documents.Model.FloatingBlockHorizontalPosition(Telerik.Windows.Documents.Model.FloatingBlocks.HorizontalRelativeFrom.Page, 250);

image.VerticalPosition = new Telerik.Windows.Documents.Model.FloatingBlockVerticalPosition(Telerik.Windows.Documents.Model.FloatingBlocks.VerticalRelativeFrom.Page, 250);

 

doc.EnsureDocumentMeasuredAndArranged();

doc.InsertInline(image);

 

pdfExp.Export(doc, stream);

I hope this helps.
