                        stream.Position = 0;
                        byte[] buffer = new byte[(int)stream.Length];
                        stream.Read(buffer, 0, (int)stream.Length);

Hi Sarvesh,

You cannot convert image stream into PDF document directly. Instead you need to create a new Siberix.Report.Report element add a Section and your image inside that section. Please take a look at the Elements example (available for download with the evaluation package for the Report Writer for WinStore) that shows how to proper use image and other resources while generating PDF reports. In short, it should look something like this:

private async Task GeneratePDFAsync(string fileName)

{

StorageFile file = await KnownFolders.DocumentsLibrary.CreateFileAsync(fileName, CreationCollisionOption.ReplaceExisting);

using (Stream stream = await file.OpenStreamForWriteAsync())

{

await Task.Run(async delegate() // Always run resource loading and report generation in a separate task

{

// Report

Siberix.Report.Report report = new Siberix.Report.Report();

// Section

Siberix.Report.Section.ISection section = report.AddSection();

section.Size = Siberix.Report.PageSize.Letter;

section.Spacings.All = 35;

string localFile = @"Assets\Logo.png";

StorageFolder InstallationFolder = Windows.ApplicationModel.Package.Current.InstalledLocation;

StorageFile file1 = await InstallationFolder.GetFileAsync(localFile);

using (Stream stream = await file1.OpenStreamForReadAsync())

{

stream.Position = 0;

byte[] buffer = new byte[(int)stream.Length];

stream.Read(buffer, 0, (int)stream.Length);

Siberix.Graphics.Image img1 = new Siberix.Graphics.Image(new MemoryStream(buffer)); // This is an image resource that could be used multiple times in your report.

Siberix.Report.IImage image = section.AddImage(img1); // This is an image element that uses the resource for display at particular place in the report

image.Width = new Siberix.Report.DirectWidth(500);

}

report.Publish(stream, Siberix.Report.FileFormat.PDF);

});

await stream.FlushAsync();

}

await Windows.System.Launcher.LaunchFileAsync(file);

}

Please let me know if you were able to resolve the issue.

Thank You,

Hi Sarvesh,

Siberix Report Writer doesn't provide any methods to directly convert XAML pages into PDF documents. However, you may use Report Writer's API or internal XML format (that is similar to XAML) to recreate the appearance of your XAML pages with the appropriate Report Writer elements.

Thank You,

Victor

Hi Sarvesh,

The easiest way to accomplish your task is to use the Grid element from the Report Writer's API. As you get a bit more "fluent" with the structure of the API you may move to XML definitions and Data Bindings.

Siberix.Report.Report report = new Siberix.Report.Report();

Siberix.Report.Text.Style style1 = new Siberix.Report.Text.Style(fnt1, Siberix.Graphics.Brushes.Black);

// Grid

Siberix.Report.Grid.IGrid grid = section.AddGrid();

grid.Borders = new Siberix.Report.Borders(Siberix.Graphics.Pens.Black);

Siberix.Report.Grid.IColumn column = grid.AddColumn();

column.Width = new Siberix.Report.RelativeWidth(40);

column = grid.AddColumn();

column.Width = new Siberix.Report.RelativeWidth(60);

// First Row

Siberix.Report.Grid.IRow row = grid.AddRow();

Siberix.Report.Grid.ICell cell = row.AddCell();

cell.Borders = new Siberix.Report.Borders(Siberix.Graphics.Pens.Black);

Siberix.Report.Text.IText text = cell.AddText();

text.Style = style1;

text.AddContent("Name :");

cell = row.AddCell();

cell.Borders = new Siberix.Report.Borders(Siberix.Graphics.Pens.Black);

text = cell.AddText();

text.Style = style1;

text.AddContent(someObject.XXXX); // XXXX should be a string property of someObject

// Second row

row = grid.AddRow();

cell = row.AddCell();

cell.Borders = new Siberix.Report.Borders(Siberix.Graphics.Pens.Black);

Siberix.Report.Text.IText text = cell.AddText();

text.Style = style1;

text.AddContent("Fathers Name :");

cell = row.AddCell();

cell.Borders = new Siberix.Report.Borders(Siberix.Graphics.Pens.Black);

text = cell.AddText();

text.Style = style1;

text.AddContent(someObject.rrrrrrr); // rrrrrrr should be a string property of someObject

...

report.Publish(...);

Thank You,

Victor

Hi Sarvesh,

It is hard to say what's the issue based only on the description of the problem. Could you please send your report generation (Grid creation) code to in...@siberix.com. I'll take a look at your code and let you know how to resolve the problem.

Thank You,

Victor
