Simulates bold text in Java

Making QR Code 2d barcode in Java Simulates bold text

You can change the width of a Chunk with the setScaling() method. In the top right of figure 3.8, the words Foobar Film Festival are scaled to 50 percent of their width, but the height of the glyphs is preserved. This means that the aspect ratio of the letters is changed. You have to be careful not to exaggerate the scaling. At some point, your text will become almost illegible. The setSkew() method expects two parameters. With the first parameter, you change the angle of the baseline. That s what happened in the second line on the right side of figure 3.8: the angle of the baseline is changed to 15 degrees. The second parameter can be used to define the angle between the characters and the baseline. The third line on the right in figure 3.8 looks as if an italic font were used. In reality, the glyphs were skewed 25 degrees.

If you have to use a font for which you can t find the corresponding font with italic or oblique style, you can use setSkew(0, 25) to simulate italics.

Finally, there s the setTextRenderMode() method. These are possible values for the first parameter:

so that the glyphs are filled and stroked. This state was used in figure 3.1 to cover existing content with the words SOLD OUT in white letters with red contours. PdfContentByte.TEXT_RENDER_MODE_INVISIBLE This will make all the text that is added invisible. The text will be there, but it won t be visible.

Two extra parameters define the line width and the color that will be used to stroke the glyph. If you pass a null value for the stroke color, the fill color (defined in the Chunk s Font object) will be used. The final line in figure 3.8 looks as if a bold font were used. If you have to use a font for which you can t find the corresponding font with bold style, you could use setTextRenderMode(PdfContentByte .TEXT_ RENDER_MODE_FILL_STROKE, 0.5f, null) to simulate bold.

These attributes also work if you re adding Chunks with document.add(). The timetable for the film festival is almost finished, as you can see in figure 3.9.

The only bits of information missing in the figure are the movie titles. It would be nice if you could add the text to the rectangles without having to scale the text or downsize the font size if the title is too long to fit the width of the rectangle. This can t be done with the showTextAligned() method, to which you only pass a single set of (x,y) coordinates; you need an instance of the ColumnText object instead.

In this section, you ll learn about the different ways to use the ColumnText object: text mode if you only use Chunks and Phrases, composite mode if you want to use other types of high-level objects as well. In listing 3.13, you wrote a showMovieInfo() method. If a screening was reserved for the press, you marked the corresponding time block of the movie with a white, uppercase P . You could try adding the movie title the same way, but the showTextAligned() method isn t able to wrap text. You also can t use newlines in Strings or Chunks using any version of this method. Let s extend the previous example and reuse almost all of its methods. The only change involves the drawMovieInfo() method.

protected void drawMovieInfo( Screening screening, PdfContentByte directcontent) throws DocumentException { super.drawMovieInfo(screening, directcontent); Rectangle rect = getPosition(screening); ColumnText column = new ColumnText(directcontent); column.setSimpleColumn( new Phrase(screening.getMovie().getMovieTitle()), rect.getLeft(), rect.getBottom(), rect.getRight(), rect.getTop(), Draws content 18, Element.ALIGN_CENTER); of column column.go(); }
