You tell iText where to find the font programs for Times New Roman (times.ttf) and Times New Roman Bold (timesbd.ttf) by creating a BaseFont object. You ask iText to embed the characters (BaseFont.EMBEDDED versus BaseFont.NOT_EMBEDDED) using the ANSI character set (BaseFont.WINANSI). You ll learn more about the BaseFont object in chapter 11. For now, it s sufficient to know that you can create a Font instance using a BaseFont object and a float value for the font size. Figure 2.5 looks very similar to figure 2.4; only now the PDF file is rendered the same way in both viewers.
Figure 2.5 A PDF file opened in Adobe Reader and Evince on Ubuntu
Using iText s basic building blocks
Observe that there s more space between the names in this version because listing 2.5 used setLeading() to change the leading. The names of the directors are also underlined differently compared to the previous example, because you don t define the underlining as a property of the Font, but as an attribute of the Chunk. With the Chunk.setUnderline() method, you can set the line thickness (in the example, 0.2 pt) and a Y position (in the example, 2 pt below the baseline). The parameter that sets the Y position allows you to use the same method to strike a line through a Chunk. There s also a variant of the method that accepts six parameters:
A BaseColor, which makes the line a different color than the text. The absolute thickness. A thickness multiplication factor that will adapt the line width based on the font size. An absolute Y position. A position multiplication factor that will adapt the Y position based on the font size. The end line cap, defining what the extremities of the line should look like. Allowed values are PdfContentByte.LINE_CAP_BUTT (the default value), PdfContentByte.LINE_CAP_ROUND, and PdfContentByte.LINE_CAP_PROJECTING_ SQUARE. The meaning of these options will be explained in table 14.6.
One thing may look peculiar when you look at figure 2.5. Why do both viewers still list Helvetica You won t find any explicit reference to it in listings 2.4 and 2.5, but it s added implicitly in this line:
document.add(Chunk.NEWLINE);
Chunk.NEWLINE contains a newline character in the default font; and the default font is Helvetica. You could have avoided this by replacing that line with this one:
document.add(new Chunk("\n", NORMAL));
But an even better solution would be to use a Paragraph object instead of a Phrase.
Paragraph object: a Phrase with extra properties and a newline
Although the analogy isn t entirely correct, I often compare the difference between a Phrase and a Paragraph in iText with the difference between <span> and <div> in HTML. If you had used a Paragraph instead of a Phrase in the previous examples, it wouldn t have been necessary to add a newline.
Listing 2.6 MovieTitles.java
List<Movie> movies = PojoFactory.getMovies(connection); for (Movie movie : movies) { document.add(new Paragraph(movie.getTitle())); }
Adding Chunk, Phrase, Paragraph, and List objects
The Paragraph class is derived from the Phrase class. You can create instances of Paragraph exactly the same way as you ve been creating Phrase objects, but there s more: you can also define the alignment of the text, different indentations, and the spacing before and after the paragraph.
