Placing Image in PDF

it-yeq · July 31, 2021, 11:00pm

Hi,

I have used different methods to place an image on a PDF page (for example Add Image to PDF using C#|Aspose.PDF for .NET and Set Image Size|Aspose.PDF for .NET and also with the AddImage method of the page).
All work BUT the image is always placed “behind” other elements on the page (for example a rectangle…).

How can I define z-order of image?

Best Regards

One example source code (with AddImage):

        using (System.IO.MemoryStream vMStream = new System.IO.MemoryStream(Properties.Resources.NotoSans_Bold))
        {
            Font = Aspose.Pdf.Text.FontRepository.OpenFont(vMStream, Aspose.Pdf.Text.FontTypes.OTF);
        };

        using (var vPDFDoc = new Aspose.Pdf.Document())
        {

            vPDFDoc.DisableFontLicenseVerifications = true;

            vPDFDoc.PageLayout = Aspose.Pdf.PageLayout.SinglePage;

            var vPDFPage = vPDFDoc.Pages.Add();
            var vPageSize = new Aspose.Pdf.PageSize(Aspose.Pdf.PageSize.A3.Width, Aspose.Pdf.PageSize.A3.Height) { IsLandscape = true };
            vPDFPage.SetPageSize(vPageSize.Width, vPageSize.Height);

            vPDFPage.PageInfo.Margin = new Aspose.Pdf.MarginInfo(0, 0, 0, 0);

            var vPageFullRECT = vPDFPage.GetPageRect(true);
            var vPageGrossRECT = new Aspose.Pdf.Rectangle((vPageFullRECT.Width * 15) / 1000, (vPageFullRECT.Height * 15) / 1000, (vPageFullRECT.Width * 985) / 1000, (vPageFullRECT.Height * 985) / 1000);

            var vCurrY = vPageGrossRECT.URY;

            var vX = 0.0;

            var vW = vPDFPage.Rect.Width;
            var vH = (40.0 / 297.0) * vPDFPage.Rect.Height;
            var vY = vCurrY - vH;


            Aspose.Pdf.Drawing.Graph vG = new Aspose.Pdf.Drawing.Graph((float)vPageFullRECT.Width, (float)vPageFullRECT.Height) { IsInLineParagraph = true, IsChangePosition = false };

            var vRect2Draw = new Aspose.Pdf.Drawing.Rectangle((float)vX, (float)vY, (float)vW, (float)vH);
            vRect2Draw.GraphInfo.Color = Aspose.Pdf.Color.Black;
            vRect2Draw.GraphInfo.FillColor = Aspose.Pdf.Color.FromRgb(208.0 / 255.0, 2.0 / 255.0, 27.0 / 255.0);
            vRect2Draw.GraphInfo.LineWidth = 1;

            string vText = "TOP-HIT";

            var vCurrX = vX;
            var vFontSize = 100;

            var vTextFontSize = 100;
            vCurrY = vY + 130;

            vX = vX + 1.5;
            vY = vY + 1.5;
            vW = vW - 3;
            vH = vH - 3;

            Aspose.Pdf.Text.TextFragment textFragment = new Aspose.Pdf.Text.TextFragment(vText);
            textFragment.IsInLineParagraph = true;

            textFragment.Position.XIndent = 0;
            textFragment.Position.YIndent = vY / 2;
            textFragment.HorizontalAlignment = Aspose.Pdf.HorizontalAlignment.Center;
            textFragment.VerticalAlignment = Aspose.Pdf.VerticalAlignment.Center;
            textFragment.TextState.Font = Font;
            textFragment.TextState.FontSize = (float)vTextFontSize;
            textFragment.TextState.ForegroundColor = Aspose.Pdf.Color.FromRgb(248.0 / 255.0, 231.0 / 255.0, 28.0 / 255.0);
            textFragment.TextState.DrawTextRectangleBorder = true;

            textFragment.TextState.FormattingOptions = new Aspose.Pdf.Text.TextFormattingOptions();
            textFragment.TextState.FormattingOptions.WrapMode = Aspose.Pdf.Text.TextFormattingOptions.WordWrapMode.ByWords;
            textFragment.TextState.FormattingOptions.LineSpacing = Aspose.Pdf.Text.TextFormattingOptions.LineSpacingMode.FullSize;
            textFragment.ZIndex = 100;

            vG.Shapes.Add(vRect2Draw);
            vG.Shapes[0].Text = textFragment;
            vPDFPage.Paragraphs.Add(vG);

            vPDFPage.Paragraphs.Add(textFragment);

            using (var vImageStream = new System.IO.MemoryStream(System.IO.File.ReadAllBytes(vF)))
            {
                vPDFPage.AddImage(vImageStream, new Aspose.Pdf.Rectangle(0, vPageFullRECT.Height - 200, 200, vPageFullRECT.Height));

                vPDFDoc.Save("test.pdf");
            };
        };

@it-yeq

We tried using image stamp and have set the z-index of Graph to -1 to render the image above it but we were not able to achieve the expected results. Therefore, an investigation ticket as PDFNET-50299 has been logged in our issue management system. We will further look into its details and keep you posted with the status of its resolution. Please be patient and spare us some time.

Hi,

Is it possible to get this somehow fixed within the next 4 weeks? Is there something like a paid fix?

Thanks in advance.

Best Regards

@it-yeq

We are investigating the earlier logged ticket. We would like to get more information for analysis.
In your example, there are two identical inscriptions and it is unclear which one was earlier and which one was added. It is better to use different labels. Can you please share output files generated at your end for each of the methods used?

it-yeq · November 15, 2022, 8:41pm

@asad.ali
I am not sure what you mean by “identical inscriptions”?

asad.ali · November 15, 2022, 9:52pm

@it-yeq

If you check the output generated by using complete example of yours, you can see that there are two images inside it. One is added by using ImageStamp and other is drawn using Graph functionality: image.png (4.8 KB)

We request can you please share two output files i.e. one generated using Graph only in your environment and other using Image Stamp?

Before adding an image, you need to invoke pdfDocument.ProcessParagraphs() method to apply changes:

using (var vPDFDoc = new Aspose.Pdf.Document())
{
    vPDFDoc.DisableFontLicenseVerifications = true;
    vPDFDoc.PageLayout = Aspose.Pdf.PageLayout.SinglePage;

    var vPDFPage = vPDFDoc.Pages.Add();
    var vPageSize = new Aspose.Pdf.PageSize(Aspose.Pdf.PageSize.A3.Width, Aspose.Pdf.PageSize.A3.Height) { IsLandscape = true };
    vPDFPage.SetPageSize(vPageSize.Width, vPageSize.Height);
    vPDFPage.PageInfo.Margin = new Aspose.Pdf.MarginInfo(0, 0, 0, 0);

    var vPageFullRECT = vPDFPage.GetPageRect(true);
    var vPageGrossRECT = new Aspose.Pdf.Rectangle((vPageFullRECT.Width * 15) / 1000, (vPageFullRECT.Height * 15) / 1000, (vPageFullRECT.Width * 985) / 1000, (vPageFullRECT.Height * 985) / 1000);
    var vCurrY = vPageGrossRECT.URY;

    var vX = 0.0;
    var vW = vPDFPage.Rect.Width;
    var vH = (40.0 / 297.0) * vPDFPage.Rect.Height;
    var vY = vCurrY - vH;

    Aspose.Pdf.Drawing.Graph vG = new Aspose.Pdf.Drawing.Graph((float)vPageFullRECT.Width, (float)vPageFullRECT.Height) { IsInLineParagraph = true, IsChangePosition = false };
    vG.ZIndex = -1;

    var vRect2Draw = new Aspose.Pdf.Drawing.Rectangle((float)vX, (float)vY, (float)vW, (float)vH);
    vRect2Draw.GraphInfo.Color = Aspose.Pdf.Color.Black;
    vRect2Draw.GraphInfo.FillColor = Aspose.Pdf.Color.FromRgb(208.0 / 255.0, 2.0 / 255.0, 27.0 / 255.0);
    vRect2Draw.GraphInfo.LineWidth = 1;

    string vText = "TOP-HIT";

    var vCurrX = vX;
    var vFontSize = 100;
    var vTextFontSize = 100;
    vCurrY = vY + 130;
    vX = vX + 1.5;
    vY = vY + 1.5;
    vW = vW - 3;
    vH = vH - 3;

    Aspose.Pdf.Text.TextFragment textFragment = new Aspose.Pdf.Text.TextFragment(vText);
    textFragment.IsInLineParagraph = true;
    textFragment.Position.XIndent = 0;
    textFragment.Position.YIndent = vY / 2;
    textFragment.HorizontalAlignment = Aspose.Pdf.HorizontalAlignment.Center;
    textFragment.VerticalAlignment = Aspose.Pdf.VerticalAlignment.Center;
    textFragment.TextState.Font = FontRepository.FindFont("Arial");
    textFragment.TextState.FontSize = (float)vTextFontSize;
    textFragment.TextState.ForegroundColor = Aspose.Pdf.Color.FromRgb(248.0 / 255.0, 231.0 / 255.0, 28.0 / 255.0);
    textFragment.TextState.DrawTextRectangleBorder = true;
    textFragment.TextState.FormattingOptions = new Aspose.Pdf.Text.TextFormattingOptions();
    textFragment.TextState.FormattingOptions.WrapMode = Aspose.Pdf.Text.TextFormattingOptions.WordWrapMode.ByWords;
    textFragment.TextState.FormattingOptions.LineSpacing = Aspose.Pdf.Text.TextFormattingOptions.LineSpacingMode.FullSize;
    textFragment.ZIndex = 100;

    vG.Shapes.Add(vRect2Draw);
    vG.Shapes[0].Text = textFragment;
    vPDFPage.Paragraphs.Add(vG);
    vPDFPage.Paragraphs.Add(textFragment);

    using (var vImageStream = new System.IO.MemoryStream(System.IO.File.ReadAllBytes(dataDir + "aspose.png")))
    {
        ImageStamp stamp = new ImageStamp(vImageStream);
        stamp.Background = false;
        stamp.XIndent = 200;
        stamp.YIndent = vPageFullRECT.Height - 100;
        stamp.Height = 100;
        stamp.Width = 200;

        vPDFPage.AddStamp(stamp);
        vPDFDoc.Save(dataDir + "test.pdf");
    }
}
