How to place images dynamically using Aspose.PDF in C#?

I have a C# script where I am using the Aspose.PDF library. I am trying to place multiple images with a bit of a spacing vertically.

Here is what I am doing. 

  // Create pdf document
        Aspose.Pdf.Document document = new Aspose.Pdf.Document();
        Aspose.Pdf.Page page = document.Pages.Add();


        Aspose.Pdf.Text.TextFragment text = new Aspose.Pdf.Text.TextFragment("Einstein Picture");
        page.Paragraphs.Add(text);

        Aspose.Pdf.Rectangle rectangle = new Aspose.Pdf.Rectangle(100, 600, 300, 800);
        Aspose.Pdf.Rectangle rectangle1 = new Aspose.Pdf.Rectangle(100, 400, 300, 800);

        page.AddImage("C:/Users/Alan/Desktop/image.gif", rectangle);
        page.AddImage("C:/Users/Alan/Desktop/s.jpeg", rectangle1);


        document.Save("C:/Users/Alan/Desktop/Testpdf.pdf", Aspose.Pdf.SaveFormat.Pdf);

How can I perfectly align pictures vertically with a bit of gap no matter how many pictures there are?

Currently the picture looks like this. PDF image

Solution

  • I request you to use below code snippet on your end and then share your kind feedback with us. This will enable you to place multiple images with a bit vertical spacing.

            // Instantiate Document object
        var pdf = new Aspose.Pdf.Document();
        //Add a page to the document
        var pdfImageSection = pdf.Pages.Add();
        DirectoryInfo dir = new DirectoryInfo(@"D:\Aspose Files\images\");
        FileInfo[] files = dir.GetFiles("*.jpg");
        //Iterate through multiple images
        foreach (var file in files)
        {
            FileStream stream = new FileStream(file.FullName, FileMode.Open);
            System.Drawing.Image img = new System.Drawing.Bitmap(stream);
            var image = new Aspose.Pdf.Image { ImageStream = stream };
            //Set appearance properties
            image.FixHeight = 300;
            image.FixWidth = 300;
            //Set margins for proper spacing and alignment
            image.Margin = new MarginInfo(5, 5, 5, 5);
            //Add the image to paragraphs of the document
            pdfImageSection.Paragraphs.Add(image);
        }
        //Save resultant document
        pdf.Save(@"D:\Aspose Files\Image2Pdf_out.pdf");

    You were simply adding an image on a PDF page whereas this code snippet adds an image to Paragraphs collection and setting the margin property of image object fixes the alignment and spacing of the images.
