header("Content-Disposition:inline; filename=coords.pdf");
echo $buf;
pdf_delete($pdf);
?>
Figure 10-4 shows the output of Example 10-4.
Figure 10-4. Different text alignments
The pdf_show_boxed( ) function returns the number of characters that did not fit in
the box. If the feature parameter is present, it must be set to the string "blind". This
prevents the text from being drawn on the page and is useful for checking whether a
string will fit in the box without actually drawing it.
Text Attributes
There are three common ways to alter the appearance of text. One is to underline,
overline, or strike out the text using parameters. Another is to change the stroking
and filling. The third is to change the text’s color.
Each of the underline, overline, and strikeout parameters may be set to "true" or
"false" independently of the others. For example:
pdf_set_parameter($pdf, "underline", "true"); // enable underlining
