How to Create PDF Template Document with C#
Template is offered to people who don’t know how to set format for one document or table. Users can fill with contents according to the template or modify it to get better format.
Generally speaking, one template document may include font style and color, spacing and alignment. If the document has several pages, the template may include page number, header and footer of each page.
PDF is one of the most frequently used formats. Therefore, I want to talk something about PDF template, including text and paragraph settings, header and footer, page number.
Actually, we can use Adobe Acrobat to meet our requirements. Some users have concluded instruction about how to use Adobe Acrobat to operate PDF. We just search for these guides and then create a PDF template file.
But the method I will introduce is to use C# to create PDF template. This method is based on a component, Spire.Doc. If you want to use the following code, please download and install this component firstly.
Code:
using System;
using System.Drawing;
using Spire.Pdf;
using Spire.Pdf.AutomaticFields;
using Spire.Pdf.Graphics;
namespace Template
{
class Program
{
static void Main(string[] args)
{
//Create a pdf document.
PdfDocument doc = new PdfDocument();
doc.ViewerPreferences.PageLayout = PdfPageLayout.TwoColumnLeft;
//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(3.17f, PdfGraphicsUnit.Centimeter, PdfGraphicsUnit.Point);
margin.Right = margin.Left;
SetDocumentTemplate(doc, PdfPageSize.A4, margin);
//create section
PdfSection section = doc.Sections.Add();
section.PageSettings.Size = PdfPageSize.A4;
section.PageSettings.Margins = new PdfMargins(0);
SetSectionTemplate(section, PdfPageSize.A4, margin, "Section 1");
// Create one page
PdfNewPage page = section.Pages.Add();
//Draw page
DrawPage(page);
page = section.Pages.Add();
DrawPage(page);
page = section.Pages.Add();
DrawPage(page);
page = section.Pages.Add();
DrawPage(page);
page = section.Pages.Add();
DrawPage(page);
//Save pdf file.
doc.SaveToFile("Template.pdf");
doc.Close();
//Launching the Pdf file.
System.Diagnostics.Process.Start("Template.pdf");
}

How to Set PDF Font Using C#
In order to have a wonderful layout, people set formatting when they post articles to their blogs or submit their electronic document to article websites.
Font is one part of format settings, including font style and color. Generally speaking, the most frequently used font styles are Times New Roman and Arial. Also, there are many other font styles, including some special font, for example, Chinese font, Japanese font and so on.
How should we do to set font in PDF? Actually, people can set formatting well in Word and then convert it to PDF. However, it is possible that the format will lost during conversion. Therefore, some professional editors are developed for editing PDF documents. Of course, the most famous is Adobe Acrobat, which specializes in operating PDF documents.
In this post, I want to introduce one method to set PDF font by using C#. The following code can show you how to set various font styles, including special styles. And I hope that this method can be helpful for programmers who want to edit PDF font programmatically.
Before using the code, you need to install one component: Spire.PDF firstly. And add the DLL file as reference to your project.
Using the Code:
using System;
using System.Drawing;
using Spire.Pdf;
using Spire.Pdf.Graphics;
namespace Font
{
class Program
{
static void Main(string[] args)
{
//Create a pdf document.
PdfDocument doc = new PdfDocument();
// Create one page
PdfPageBase page = doc.Pages.Add();
//Draw the text
float l = page.Canvas.ClientSize.Width / 2;
PointF center = new PointF(l, l);
float r = (float)Math.Sqrt(2 * l * l);
PdfRadialGradientBrush brush
= new PdfRadialGradientBrush(center, 0f, center, r, Color.Blue, Color.Red);
PdfFontFamily[] fontFamilies
= (PdfFontFamily[])Enum.GetValues(typeof(PdfFontFamily));
float y = 10;
for (int i = 0; i < fontFamilies.Length; i++)
{
String text = String.Format("Font Family: {0}", fontFamilies[i]);
float x1 = 0;
y = 10 + i * 16;
PdfFont font1 = new PdfFont(PdfFontFamily.Courier, 14f);
PdfFont font2 = new PdfFont(fontFamilies[i], 14f);
float x2 = x1 + 10 + font1.MeasureString(text).Width;
page.Canvas.DrawString(text, font1, brush, x1, y);
page.Canvas.DrawString(text, font2, brush, x2, y);
}
//true type font - embedded.
System.Drawing.Font font = new System.Drawing.Font("Arial", 14f, FontStyle.Bold);
PdfTrueTypeFont trueTypeFont = new PdfTrueTypeFont(font);
page.Canvas.DrawString("Font Family: Arial - Embedded", trueTypeFont, brush, 0, (y = y + 16f));
//right to left
String arabicText
= "u0627u0644u0630u0647u0627u0628u0021u0020"
+ "u0628u062Fu0648u0631u0647u0020u062Du0648u0644u0647u0627u0021u0020"

trueTypeFont = new PdfTrueTypeFont(font, true);
RectangleF rctg = new RectangleF(new PointF(0, (y = y + 16f)), page.Canvas.ClientSize);
PdfStringFormat format = new PdfStringFormat(PdfTextAlignment.Right);
format.RightToLeft = true;
page.Canvas.DrawString(arabicText, trueTypeFont, brush, rctg, format);
//true type font - not embedded
font = new System.Drawing.Font("Batang", 14f, FontStyle.Italic);
trueTypeFont = new PdfTrueTypeFont(font);
page.Canvas.DrawString("Font Family: Batang - Not Embedded", trueTypeFont, brush, 0, (y = y + 16f));
//font file
String fontFileName = "Hawaii_Killer.ttf";
trueTypeFont = new PdfTrueTypeFont(fontFileName, 20f);
page.Canvas.DrawString("Hawaii Killer Font", trueTypeFont, brush, 0, (y = y + 16f));
page.Canvas.DrawString("Hawaii Killer Font, from http://www.1001freefonts.com",
new PdfFont(PdfFontFamily.Helvetica, 8f), brush, 10, (y = y + 20f));
//cjk font
PdfCjkStandardFont cjkFont = new PdfCjkStandardFont(PdfCjkFontFamily.MonotypeHeiMedium, 14f);
page.Canvas.DrawString("How to say 'Font' in Chinese? u5B57u4F53",
cjkFont, brush, 0, (y = y + 16f));
cjkFont = new PdfCjkStandardFont(PdfCjkFontFamily.HanyangSystemsGothicMedium, 14f);
page.Canvas.DrawString("How to say 'Font' in Japanese? u30D5u30A9u30F3u30C8",
cjkFont, brush, 0, (y = y + 16f));
cjkFont = new PdfCjkStandardFont(PdfCjkFontFamily.HanyangSystemsShinMyeongJoMedium, 14f);
page.Canvas.DrawString("How to say 'Font' in Korean? uAE00uAF34",
cjkFont, brush, 0, (y = y + 16f));
//Save pdf file.
doc.SaveToFile("Font.pdf");
doc.Close();
//Launching the Pdf file.
System.Diagnostics.Process.Start("Font.pdf");
