Description

This article shows a sample approach of generating a PDF expense report. The report is purposed to contain receipt images (e.g. gas, toll, meal) or PDF attachments of receipts.

Solution

To achieve this, use RadPdfProcessing from the Telerik Document Processing libraries. The library provides functionality for creating PDF documents, inserting images, embedding files, and merging multiple PDF documents.

Steps to generate the PDF report

1. Create a new instance of RadFixedDocument.
2. Add a new page to the document.
3. Use FixedContentEditor to draw text, images, and other content onto the page.
4. Embed images and PDF files as attachments using EmbeddedFiles.Add().
5. Export the constructed document to a PDF file using PdfFormatProvider.

Code Example

The following code demonstrates creating a PDF report containing embedded images and PDF files:

csharp

internal class Program
{
    static void Main(string[] args)
    {
        string outputFilePath = "ExpenseReport.pdf";
        File.Delete(outputFilePath);
        string receiptImagePath = "receipt.png"; // Replace with your image path
        string receiptPdfPath = "sample_receipt.pdf"; // Replace with your PDF path
        Build("John Smith", "January 2026", receiptImagePath, receiptPdfPath, outputFilePath);

        Process.Start(new ProcessStartInfo() { FileName = outputFilePath, UseShellExecute = true });
    }

    public static void Build(string employeeName,
                             string periodLabel,
                             string receiptImagePath,
                             string receiptPdfPath,
                             string outputPdfPath)
    {
        var document = new RadFixedDocument();
        var page = document.Pages.AddPage();
        var editor = new FixedContentEditor(page);
        const double left = 50, top = 50;
        editor.Position.Translate(left, top);

        var h1 = new Block();
        h1.TextProperties.FontSize = 20;
        h1.TextProperties.Font = FontsRepository.TimesBold;
        h1.InsertText("Expense Report");
        editor.DrawBlock(h1);
        editor.Position.Translate(editor.Position.Matrix.OffsetX + 50, editor.Position.Matrix.OffsetY + 50);

        var info = new Block();
        info.SpacingBefore = 6;
        info.TextProperties.FontSize = 12;
        info.InsertText($"Employee: {employeeName}\n");
        info.InsertText($"Period:   {periodLabel}\n");
        editor.DrawBlock(info);
        editor.Position.Translate(editor.Position.Matrix.OffsetX, editor.Position.Matrix.OffsetY + 50);

        var note = new Block();
        note.SpacingBefore = 8;
        note.TextProperties.FontSize = 10;
        note.InsertText("Note: This PDF contains embedded attachments (see the Attachments panel in your PDF viewer).");
        editor.DrawBlock(note);
        editor.Position.Translate(editor.Position.Matrix.OffsetX, editor.Position.Matrix.OffsetY + 50);

        if (File.Exists(receiptImagePath))
        {
            Telerik.Windows.Documents.Fixed.Model.Objects.Image img = new Telerik.Windows.Documents.Fixed.Model.Objects.Image();
            using (FileStream fileStream = new FileStream(receiptImagePath, FileMode.Open))
            {
                ImageSource imageSrc = new ImageSource(fileStream);
                img.ImageSource = imageSrc;
                img.Width = 500;
                img.Height = 740;
                SimplePosition simplePosition = new SimplePosition();
                simplePosition.Translate(200, 300);
                img.Position = simplePosition;
                page.Content.Add(img);
            }

            byte[] pdfBytes = File.ReadAllBytes(receiptImagePath);
            var embedded = document.EmbeddedFiles.Add(Path.GetFileName(receiptImagePath), pdfBytes);
            embedded.MimeType = "image/png";
        }

        if (File.Exists(receiptPdfPath))
        {
            byte[] pdfBytes = File.ReadAllBytes(receiptPdfPath);
            var embedded = document.EmbeddedFiles.Add(Path.GetFileName(receiptPdfPath), pdfBytes);
            embedded.MimeType = "application/pdf";
        }

        var provider = new PdfFormatProvider();
        Directory.CreateDirectory(Path.GetDirectoryName(Path.GetFullPath(outputPdfPath)) ?? ".");
        using var outStream = File.Create(outputPdfPath);
        provider.Export(document, outStream, TimeSpan.FromSeconds(10));
    }
}
