Long content is not splitting into multi pages

[jaddeveloper]

Hi,
I have a huge text content which will fit usually in more than one page but when i use the below code, the text ends by the end of the first page and it doesn't create a second page. Is there a feature to do this automatically or this need to be handled grammatically and what is the best approach (depending on text length or !! )

Code: Select all

//Document is just internal class for my data
  private void AddContent(PdfPageBase page, Document document)
        {

            PdfBrush solidBrush = new PdfSolidBrush(Color.Black);
         
            System.Drawing.Font contentFont = new System.Drawing.Font("Arial", 12f, FontStyle.Regular);
            PdfTrueTypeFont contentTrueTypeFont = new PdfTrueTypeFont(contentFont);
            contentTrueTypeFont = new PdfTrueTypeFont(contentFont, true);

            RectangleF rctgContent = new RectangleF(page.Canvas.ClientSize.Width * 0.25f, 70, page.Canvas.ClientSize.Width *     0.75f, page.Canvas.ClientSize.Height);
            PdfStringFormat rightFormat = new PdfStringFormat(PdfTextAlignment.Right);

            rightFormat.RightToLeft = true;

            page.Canvas.DrawString(document.Content + document.Content, contentTrueTypeFont, solidBrush, rctgContent, rightFormat);

            RectangleF rctgImage = new RectangleF(0, 70, page.Canvas.ClientSize.Width * 0.25f, page.Canvas.ClientSize.Width * 0.25f);
            Image img = GetImage(document.PhotosUrls[0]);
            PdfImage image = PdfImage.FromImage(img);
            page.Canvas.DrawImage(image, rctgImage);
            page.Canvas.SetTransparency(1);

        }

Hi,

Thanks for your posting and using our Spire.PDF component.
Please refer to the following solution to draw content into multi pages.

Code: Select all

PdfDocument doc = new PdfDocument();
            PdfSection section = doc.Sections.Add();
            PdfPageBase page = section.Pages.Add();
            PdfFont font = new PdfFont(PdfFontFamily.Helvetica, 11);

            PdfStringFormat format = new PdfStringFormat(PdfTextAlignment.Right);
            format.LineSpacing = 20f;
            format.RightToLeft = true;
            PdfBrush brush = PdfBrushes.Black;

            PdfTextWidget textWidget = new PdfTextWidget(text, font, brush);

            float y = 0;

            PdfTextLayout textLayout = new PdfTextLayout();

            textLayout.Break = PdfLayoutBreakType.FitPage;

            textLayout.Layout = PdfLayoutType.Paginate;

            RectangleF bounds = new RectangleF(new PointF(0, y), page.Canvas.ClientSize);

            textWidget.StringFormat = format;

            textWidget.Draw(page, bounds, textLayout);

            doc.SaveToFile("result.pdf", FileFormat.PDF);

Thanks for your fast reply, I got the following error

An error exist on this page. Acrobat may not display the page correctly. Please contact the person who created the PDF document.

Also the header disappear from the second page and footer got misaligned. Below how i create the header

Code: Select all

  private void AddHeader(PdfDocument doc, SizeF pageSize, PdfMargins margin, string documentTitle)
        {
            //set top page template
            PdfPageTemplateElement topSpace = new PdfPageTemplateElement(pageSize.Width, margin.Top);
            topSpace.Foreground = true;
            doc.Template.Top = topSpace;

            //drew an image in header with custom size
            PdfImage headerImage = PdfImage.FromFile("...");
            float width = 150;
            float height = 100;
            PointF pageLeftTop = new PointF(0, 0);
            topSpace.Graphics.DrawImage(headerImage, 0, 0, width / 2, height / 2);

            //drew an image in header with custom size
            PdfImage headerImage2 = PdfImage.FromFile("...");
            float width2 = 150;
            float height2 = 100;
            PointF pageRightTop = new PointF(PdfPageSize.A4.Width - width, 0);
            topSpace.Graphics.DrawImage(headerImage2, PdfPageSize.A4.Width - width2 / 2, 0, width2 / 2, height2 / 2);

            //draw text in header
            PdfTrueTypeFont font1 = new PdfTrueTypeFont(new Font("Arial", 14f, FontStyle.Bold), true);
            PdfStringFormat format = new PdfStringFormat(PdfTextAlignment.Center);
            format.RightToLeft = true;
            String label = documentTitle;
            //SizeF size = font1.MeasureString(label, format);
            float y = 15f;
            float x = (PdfPageSize.A4.Width / 2);
            topSpace.Graphics.DrawString(label, font1, PdfBrushes.Black, x, y, format);
        }

I have included the pdf result in the attachment.

Is there any email i can send the code to as i dont want to place it in public. Plus i cant send the whole text and images as most of the data are coming from web API so its not actually files

Hi,

I have some sample code about drawing header in all pages, please refer to the following code.

Code: Select all

  PdfDocument doc = new PdfDocument();
            PdfUnitConvertor unitCvtr = new PdfUnitConvertor();
            PdfMargins margin = new PdfMargins();
            margin.Top = unitCvtr.ConvertUnits(2.54f, PdfGraphicsUnit.Centimeter, PdfGraphicsUnit.Point);
            margin.Bottom = margin.Top;
            margin.Left = unitCvtr.ConvertUnits(3.17f, PdfGraphicsUnit.Centimeter, PdfGraphicsUnit.Point);
            margin.Right = margin.Left;

            AddHeader(doc, PdfPageSize.A4, margin, documentTitle);

            PdfSection section = doc.Sections.Add();
            section.PageSettings.Size = PdfPageSize.A4;
            section.PageSettings.Margins = new PdfMargins(0);
            PdfPageBase page = section.Pages.Add();

            PdfFont font = new PdfFont(PdfFontFamily.Helvetica, 11);

            PdfStringFormat format = new PdfStringFormat(PdfTextAlignment.Right);

            format.LineSpacing = 20f;
            format.RightToLeft = true;
            PdfBrush brush = PdfBrushes.Black;

            PdfTextWidget textWidget = new PdfTextWidget(text, font, brush);

            float y = 0;

            PdfTextLayout textLayout = new PdfTextLayout();

            textLayout.Break = PdfLayoutBreakType.FitPage;

            textLayout.Layout = PdfLayoutType.Paginate;

            RectangleF bounds = new RectangleF(new PointF(0, y), page.Canvas.ClientSize);

            textWidget.StringFormat = format;

            textWidget.Draw(page, bounds, textLayout); 
 doc.SaveToFile("TxtToPDf.pdf", Spire.Pdf.FileFormat.PDF);


If the above code doesn't help, please send all your code to [email protected].
Thank you.

Hi,

Thanks for your response.
Please refer to the following solution to add header and footer.

Code: Select all

 
            PdfSection section = doc.Sections.Add();
            PdfPageBase page = section.Pages.Add();

            //set margin   
            PdfUnitConvertor unitCvtr = new PdfUnitConvertor();
            PdfMargins margin = new PdfMargins();
            margin.Top = unitCvtr.ConvertUnits(2.54f, PdfGraphicsUnit.Centimeter, PdfGraphicsUnit.Point);
            margin.Bottom = margin.Top;
            margin.Left = unitCvtr.ConvertUnits(4.50f, PdfGraphicsUnit.Centimeter, PdfGraphicsUnit.Point);
            margin.Right = margin.Left;
            SetDocumentTemplate(doc, PdfPageSize.A4, margin);
static void SetDocumentTemplate(PdfDocument doc, SizeF pageSize, PdfMargins margin,string label)
        {
            PdfPageTemplateElement leftSpace
                = new PdfPageTemplateElement(margin.Left, pageSize.Height);
            doc.Template.Left = leftSpace;

            PdfPageTemplateElement topSpace
                = new PdfPageTemplateElement(pageSize.Width, margin.Top);
            topSpace.Foreground = true;
            doc.Template.Top = topSpace;
            PdfImage headerImage = PdfImage.FromFile(@"..\\..\\logo1.png");
            float width = 150;
            float height = 100;
            PointF pageLeftTop = new PointF(0, 0);
            topSpace.Graphics.DrawImage(headerImage, 0, 0, width / 2, height / 2);

            //drew an image in header with custom size
            PdfImage headerImage2 = PdfImage.FromFile(@"..\\..\\logo2.png");
            float width2 = 150;
            float height2 = 100;
            PointF pageRightTop = new PointF(PdfPageSize.A4.Width - width, 0);
            topSpace.Graphics.DrawImage(headerImage2, PdfPageSize.A4.Width - width2 / 2, 0, width2 / 2, height2 / 2);
            //draw header label
            PdfTrueTypeFont font = new PdfTrueTypeFont(new Font("Arial", 9f, FontStyle.Italic));
            PdfStringFormat format = new PdfStringFormat(PdfTextAlignment.Right);
            format.RightToLeft = true;
            SizeF size = font.MeasureString(label, format);
            float y = topSpace.Height - font.Height - 1;
            PdfPen pen = new PdfPen(Color.Black, 0.75f);
            topSpace.Graphics.SetTransparency(0.5f);
            topSpace.Graphics.DrawLine(pen, 0, y, pageSize.Width, y);
            y = y - 1 - size.Height;
            topSpace.Graphics.DrawString(label, font, PdfBrushes.Black, pageSize.Width / 2 - size.Width / 2 + topSpace.Width,y, format);

            PdfPageTemplateElement rightSpace
                = new PdfPageTemplateElement(margin.Right, pageSize.Height);
            doc.Template.Right = rightSpace;

            PdfPageTemplateElement bottomSpace
                = new PdfPageTemplateElement(pageSize.Width, margin.Bottom);
            bottomSpace.Foreground = true;
            doc.Template.Bottom = bottomSpace;

            //draw footer label
            y = font.Height + 1;
            bottomSpace.Graphics.SetTransparency(0.5f);
            bottomSpace.Graphics.DrawLine(pen, 0, y, pageSize.Width, y);
            y = y + 1;
            bottomSpace.Graphics.DrawString("Confidential", font, PdfBrushes.Black,0,y, new PdfStringFormat(PdfTextAlignment.Left));
         
            PdfPageNumberField pageNumber = new PdfPageNumberField();
            PdfPageCountField pageCount = new PdfPageCountField();
            PdfCompositeField pageNumberLabel = new PdfCompositeField();
            pageNumberLabel.AutomaticFields
                = new PdfAutomaticField[] { pageNumber, pageCount };
            pageNumberLabel.Brush = PdfBrushes.Gray;
            pageNumberLabel.Font = font;
            pageNumberLabel.StringFormat = format;
            pageNumberLabel.Text = "page {0} of {1}";
         
            pageNumberLabel.Draw(bottomSpace.Graphics, pageSize.Width - margin.Right, y);
            bottomSpace.Graphics.SetTransparency(1f);
        }
