Aspose.pdf for .net image insertion going over text

I'm using aspose.pdf for .net and when i dynamically insert an image, the adjacent text on the pdf runs underneath the image.

I am replacing a placeholder (eg %checkboxImage%) with an actual image

enter image description here

I'm just using the code from their docs as per below

        private void AddImage(TextFragment textFragment, int imageWidth, int imageHeight, Stream stream)
        {
            var currentPage = textFragment.Page;

            var position = new Position(0, 0);
            position = textFragment.Position;
            position.YIndent = textFragment.Position.YIndent;
            textFragment.Text = "";
            if (position.XIndent != 0 && position.YIndent != 0)
            {
                // Set coordinates
                double lowerLeftX = position.XIndent;
                double lowerLeftY = position.YIndent;
                double upperRightX = position.XIndent + imageWidth;
                double upperRightY = position.YIndent + imageHeight;

                currentPage.Resources.Images.Add(stream);
                currentPage.Contents.Add(new GSave());
                var rectangle = new Rectangle(lowerLeftX, lowerLeftY, upperRightX, upperRightY);
                var matrix = new Matrix(new double[] { rectangle.URX - rectangle.LLX, 0, 0, rectangle.URY - rectangle.LLY, rectangle.LLX, rectangle.LLY - 10 });
                currentPage.Contents.Add(new ConcatenateMatrix(matrix));
                XImage ximage = currentPage.Resources.Images[currentPage.Resources.Images.Count];
                currentPage.Contents.Add(new Do(ximage.Name));
                currentPage.Contents.Add(new GRestore());
            }
        }

I've tried things like setting a margin for the image, also tried having the placeholder and the adjacent text in a separate cells of a table.

The z-index of the image is 0 perhaps it should be something else? But what?

Thanks for any ideas

You may simply add the image using ImageStamp class where you can control its position with XIndent and YIndent properties as per your requirements. Below is a sample code snippet for your kind reference, which may be modified or enhanced further.

// Open document
Document pdfDocument = new Document(dataDir+ "AddImageStamp.pdf");

// Create image stamp
ImageStamp imageStamp = new ImageStamp(dataDir + "aspose-logo.jpg");
imageStamp.Background = true;
imageStamp.XIndent = 100;
imageStamp.YIndent = 100;
imageStamp.Height = 300;
imageStamp.Width = 300;
imageStamp.Rotate = Rotation.on270;
imageStamp.Opacity = 0.5;
// Add stamp to particular page
pdfDocument.Pages[1].AddStamp(imageStamp);

dataDir = dataDir + "AddImageStamp_out.pdf";
// Save output document
pdfDocument.Save(dataDir);

If you still need any assistance then please share your source document and image file along with SSCCE code so that I may investigate and assist you accordingly.
