Apply Different Fonts in a PDF Document in Java
Spire.PDF for Java supports standard PDF fonts, TrueType fonts, private fonts as well as CJK font. The following are the steps to draw text in PDF using these fonts.
- Create a PdfDocument instance.
- Add a page and then create a brush.
- Create an instance of the PdfFont class with a standard PDF font, and then use the PdfPageBase.getCanvas().drawString() method to draw text on the page with the standard font.
- Create an instance of the PdfTrueTypeFont class with a specified font, and then draw text on the page with the TrueType font.
- Load a private font and create an instance of the PdfTrueTypeFont class with it. Then draw text on the page with the private font.
- Create an instance of PdfCjkStandardFont class with a CJK font, and then draw text on the page with the CJK font.
- Save the result document using PdfDocument.saveToFile() method.

public class PdfFonts {
public static void main(String[] args) {
//Create a PdfDocument instance
PdfDocument pdf = new PdfDocument();
//Add a page
PdfPageBase page = pdf.getPages().add();
//Create a brush

//Initialize y coordinate
float y = 30;
//Draw text using standard fonts
PdfFont standardFont = new PdfFont(PdfFontFamily.Helvetica, 14f);
page.getCanvas().drawString("Standard Font - Helvetica", standardFont, brush, 0, y);

standardFont = new PdfFont(PdfFontFamily.Courier, 14f);
page.getCanvas().drawString("Standard Font - Courier", standardFont, brush, 0, (y = y + 16));
//Draw text using truetype font
java.awt.Font font = new java.awt.Font("Arial", java.awt.Font.BOLD, 14);
PdfTrueTypeFont trueTypeFont = new PdfTrueTypeFont(font);
page.getCanvas().drawString("TrueType Font - Arial", trueTypeFont, brush, 0, (y = y + 30f));
//Draw text using private font
String fontFileName = "Khadija.ttf";
trueTypeFont = new PdfTrueTypeFont(fontFileName, 14f);
page.getCanvas().drawString("Private Font - Khadija", trueTypeFont, brush, 0, (y = y + 30f));
//Draw text using cjk fonts
PdfCjkStandardFont cjkFont = new PdfCjkStandardFont(PdfCjkFontFamily.Monotype_Hei_Medium, 14f);
page.getCanvas().drawString("How to say 'Font' in Chinese? \u5B57\u4F53", cjkFont, brush, 0, (y = y + 30f));
cjkFont = new PdfCjkStandardFont(PdfCjkFontFamily.Hanyang_Systems_Gothic_Medium, 14f);
page.getCanvas().drawString("How to say 'Font' in Japanese? \u30D5\u30A9\u30F3\u30C8", cjkFont, brush, 0, (y = y + 16f));
cjkFont = new PdfCjkStandardFont(PdfCjkFontFamily.Hanyang_Systems_Shin_Myeong_Jo_Medium, 14f);
page.getCanvas().drawString("How to say 'Font' in Korean? \uAE00\uAF34", cjkFont, brush, 0, (y = y + 16f));
