note 98674 added to function.pdf-show-boxed

As this is nowadays the poor/stingy man's alternative to the commercial PDFlib PDF_*_textflow() functions, I thought it might be useful to point out something that isn't explicitly mentioned here, but is helpful to determine a text box's height before committing it to the PDF: This function returns the number of characters that would not fit in the prescribed dimensions. Therefore, if, as noted below, the only feature, "blind", is passed as the last value to this function, you can determine whether or not a certain height is sufficient for your text, and increment as necessary, or decide to start a new page, without writing the text block to the PDF, by checking whether or not the function returns 0. This avoids the problem of the "texty" value becoming available only when the box has been written, by which time it might too late! ---- Server IP: 69.147.83.197 Probable Submitter: 78.86.171.162 ---- Manual Page -- http://www.php.net/manual/en/function.pdf-show-boxed.php Edit -- https://master.php.net/note/edit/98674 Del: integrated -- https://master.php.net/note/delete/98674/integrated Del: useless -- https://master.php.net/note/delete/98674/useless Del: bad code -- https://master.php.net/note/delete/98674/bad+code Del: spam -- https://master.php.net/note/delete/98674/spam Del: non-english -- https://master.php.net/note/delete/98674/non-english Del: in docs -- https://master.php.net/note/delete/98674/in+docs Del: other reasons-- https://master.php.net/note/delete/98674 Reject -- https://master.php.net/note/reject/98674 Search -- https://master.php.net/manage/user-notes.php
