piece of normal text. Font, font size, and encoding are specified explicitly. In the firstcall to PDF_add_textflow( ), -1 is supplied, and the Textflow handle will be returned to beused in subsequent calls to PDF_add_textflow( ), if required. text1 and text2 are assumedto contain the actual text to be printed.With PDF_fit_textflow( ), the resulting Textflow is placed in a fitbox on the page usingdefault formatting options./* Add text with bold font */tf = p.add_textflow(-1, text1, "fontname=Helvetica-Bold fontsize=9 encoding=unicode");if (tf == -1)throw new Exception("Error: " + p.get_errmsg());/* Add text with normal font */tf = p.add_textflow(tf, text2, "fontname=Helvetica fontsize=9 encoding=unicode");if (tf == -1)throw new Exception("Error: " + p.get_errmsg());/* Place all text */result = p.fit_textflow(tf, left_x, left_y, right_x, right_y, "");if (!result.equals("_stop")){ /* ... */}p.delete_textflow(tf);Placing text in two fitboxes on multiple pages. If the text placed with PDF_fit_textflow( ) doesn’t completely fit into the fitbox, the output will be interrupted and thefunction will return the string _boxfull. PDFlib will remember the amount of text alreadyplaced, and will continue with the remainder of the text when the function iscalled again. In addition, it may be necessary to create a new page. The following codefragment demonstrates how to place a Textflow in two fitboxes per page on one ormore pages until the text has been placed completely (see Figure 7.12).Cookbook A full code sample can be found in the Cookbook topic text_output/starter_textflow./* Loop until all of the text is placed; create new pages as long as more text needs* to be placed.

do{String optlist = "verticalalign=justify linespreadlimit=120%";p.begin_page_ext(0, 0, "width=a4.width height=a4.height");/* Fill the first column */result = p.fit_textflow(tf, llx1, lly1, urx1, ury1, optlist);/* Fill the second column if we have more text*/if (!result.equals("_stop"))result = p.fit_textflow(tf, llx2, lly2, urx2, ury2, optlist);p.end_page_ext("");/* "_boxfull" means we must continue because there is more text;* "_nextpage" is interpreted as "start new column"*/} while (result.equals("_boxfull") || result.equals("_nextpage"));/* Check for errors */if (!result.equals("_stop")){/* "_boxempty" happens if the box is very small and doesn't hold any text at all.*/if (result.equals( "_boxempty"))throw new Exception("Error: " + p.get_errmsg());else{/* Any other return value is a user exit caused by the "return" option;* this requires dedicated code to deal with.*/}}p.delete_textflow(tf);7.2.2 Paragraph Formatting OptionsIn the previous example we used default settings for the paragraphs. For example, thedefault alignment is left-justified, and the leading is 100% (which equals the font size).In order to fine-tune the paragraph formatting we can feed more options to PDF_add_textflow( ). For example, we can indent the text 15 units from the left and 10 unitsfrom the right margin. The first line of each paragraph should be indented by an additional20 units. The text should be justified against both margins, and the leading increasedto 140%. Finally, we’ll reduce the font size to 8 points. To achieve this, extendthe option list for PDF_add_textflow( ) as follows (see Figure 7.13):String optlist ="leftindent=15 rightindent=10 parindent=20 alignment=justify " +"leading=140% fontname=Helvetica fontsize=8 encoding=unicode";7.2.3 Inline Option Lists and MacrosThe text in Figure 7.13 is not yet perfect. The headline »Have a look at our new paperplane models!« should sit on a line of its own, should use a larger font, and should becentered. There are several ways to achieve this.7.2 Multi-Line Textflows 143
