Expanding text, which is achieved by the spread method and controlled by the spreadlimit option, is another method for controlling line breaks. This unpleasing method should be rarely used, however. Figure 8.24b demonstrates a very large maximum character distance of 5 units using spreadlimit=5. Option nofitlimit for justified text. The nofitlimit option controls how small a line can get when the nofit method is applied. Reducing the default value of 75% is preferable to forced hyphenation when the fitbox is very narrow. Figure 8.24c shows the generated text output with a minimum text width of 50%. 8.2.9 Advanced script-specific Line Breaking PDFlib implements an additional line breaking algorithm on top of the standard line breaking algorithm. This advanced line breaking algorithm is required for some scripts, and improves line breaking behavior for some other script/locale combinations even if it is not required. It can be enabled with the advancedlinebreak option. Since line breaking depends on the language of the text, the advanced line breaking algorithm honors the script option (see Table 6.2) and the locale option (see PDFlib API Reference). Advanced line breaking determines proper line break opportunities in the following situations: > For scripts in which line breaking does not rely on the presence of space characters in the text, e.g. Thai. The following Textflow option list enables advanced line breaking for Thai: > In script/locale combinations which require specific treatment of certain punctuation characters, e.g. the « and » guillemet characters used as quotation marks in French text. The following Textflow option list enables advanced line breaking for 222 Chapter 8: Text and Table Formatting (Edition for COM, .NET, and REALbasic)
French text. As a result, the guillemet characters surrounding a word will not be split apart from the word at the end of a line: Note that the locale Textflow option is different from the language text option (see Table 6.3): although the locale option can start with the same three-letter language identifier, it can optionally contain one or two additional parts. However, these will rarely be required for PDFlib. 8.2.10 Wrapping Text around Paths and Images The wrapping feature can be used to fill arbitrary shapes with text or wrap text around a path. By means of matchboxes, explicit rectangles/polygons/circles/curves or path objects you can specify wrapping areas for the Textflow. If an image contains an integrated clipping path you can wrap text around the image clipping path automatically. Wrapping text around an image with matchbox. In the first example we will place an image within the Textflow and run the text around the whole image. First the image is loaded and placed in the box at the desired position. To refer to the image by name later, define a matchbox called img when fitting the image, and specify a margin of 5 units with the option list matchbox={name=img margin=-5} as follows: result = p.fit_image(image, 50, 35, "boxsize={80 46} fitmethod=meet position=center matchbox={name=img margin=-5}"); The Textflow is added. Then we place it using the wrap option with the image’s matchbox img as the area to run around as follows (see Figure 8.25): result = p.fit_textflow(textflow, left_x, left_y, right_x, right_y, "wrap={usematchboxes={{img}}}"); Before placing the text you can fit more images using the same matchbox name. In this case the text will run around all images. Cookbook A full code sample can be found in the Cookbook topic text_output/wrap_text_around_images. Wrapping text around arbitrary paths. You can create a path object (see Section 3.2.3, »Direct Paths and Path Objects«, page 73) and use it as a wrap shape. The following fragment constructs a path object with a simple shape (a circle) and supplies it to the wrap option of fit_textflow( ). The reference point for placing the path is expressed as percentage of the fitbox’s width and height: Fig. 8.25 Wrapping text around an image with matchbox Have a look at our new paper plane models! Our paper planes are the ideal way of passing the time. We offer revolutionary new developments of the traditional common paper planes. If your lesson, conference, or lecture turn out to be deadly boring, you can have a wonderful time with our planes. All our models are folded from one paper sheet. They are exclusively folded without using any adhesive. Fig. 8.26 Wrapping text around a triangular shape Our paper planes are 50% the ideal 80% way of passing the time. We offer a lot of revolutionary brand-new developments of the traditional common paper planes. If your lesson, conference, or lecture turn out to be deadly boring, you can have a wonderful time with our planes. All our models are folded from one paper sheet. They are exclusively folded without 20% using 30% any adhesive. 80% 30% Several models are equipped with a folded landing gear. enabling a safe landing on the intended location provided that you have aimed well. Other models are able to fly loops or cover long distances. 8.2 Multi-Line Textflows 223
