Hi Exson: Sorry by the delay, I was reviewing my notes. To replace addTextWrap() and AddText() with Nicola Asuni TCPDF' functions, there are some options. I did the following (I do not know if it is the best, because I did it in a rush): addText($XPos,$YPos,$size,$text) ----------- I use public function: Text($x, $y, $txt, $fstroke=false, $fclip=false, $ffill=true, $border=0, $ln=0, $align='', $fill=false, $link='', $stretch=0, $ignore_min_height=false, $calign='T', $valign='M', $rtloff=false). Parameters: * $x (float) Abscissa of the cell origin (same as addText_$XPos). MUST. * $y (float) Ordinate of the cell origin (cell vertical coordinate from page TOP side to cell top side in dpi -72dpi = 25.4mm-. WARNING: $y = page_height – addText_$YPos). MUST. * $txt (string) String to print (same as addText_$text). MUST. To change font size, you have to use public function SetFontSize() in tcpdf/tcpdf.php. Example: $this->SetFontSize($size); $this->Text($XPos, $this->h-$YPos, $text); More info: In tcpdf/tcpdf.php, line 4870. See also: Cell(), Write(), MultiCell(), WriteHTML(), WriteHTMLCell(). addTextWrap($XPos, $YPos, $linewidth, $fontsize, $text, $Align='left', $angle=0, $test=0, $border=0, $fill=false) ------------------ I use public function: MultiCell($w, $h, $txt, $border=0, $align='J', $fill=false, $ln=1, $x='', $y='', $reseth=true, $stretch=0, $ishtml=false, $autopadding=true, $maxh=0, $valign='T', $fitcell=false). Probably it is better to use the function writeHTMLCell (see: http://www.tcpdf.org/examples/example_046.phps, a text hyphenation example). This function can be used also to replace AddText(), but it is more complex. Parameters: * $w (float) Width of cells. If 0, they extend up to the right margin of the page (same as addTextWrap_$linewidth). MUST. * $h (float) Cell minimum height. The cell extends automatically if needed (I use the same as addTextWrap_$fontsize, but I saw some reports that use a greater line_height). MUST. * $txt (string) String to print [same as addTextWrap_$text, but you must translate it to html using, as example, “html_entity_decode($text, ENT_QUOTES, 'UTF-8')” ]. MUST. * $border (mixed) Indicates if borders must be drawn around the cell. The value can be a number: 0: no border (default); 1: frame; or a string containing some or all of the following characters (in any order): L: left; T: top; R: right; B: bottom; or an array of line styles for each border group - for example: array('LTRB' => array('width' => 2, 'cap' => 'butt', 'join' => 'miter', 'dash' => 0, 'color' => array(0, 0, 0))). OPTIONAL, I recommend to input as “$border=0”. * $align (string) Allows to centre or align the text. Possible values are: L or empty string: left align; C: centre; R: right align; J: justification (default value when $ishtml=false). OPTIONAL, I do a “switch($Align) {// Translate from Pdf-Creator to TCPDF.”. * $fill (boolean) Indicates if the cell background must be painted (true) or transparent (false). OPTIONAL, I recommend to input as “$fill=false”. * $ln (int) Indicates where the current position should go after the call. Possible values are: 0: to the right; 1: to the beginning of the next line [DEFAULT]; 2: below. OPTIONAL, I recommend to input as “$ln=1” to use the return_function to control the position at the printing end. * $x (float) x position in user units (same as addTextWrap_$XPos). OPTIONAL, but I recommend to use it. * $y (float) y position in user units (cell vertical coordinate from page TOP side to cell top side in dpi -72dpi = 25.4mm-. WARNING_1: $y = page_height – addTextWrap_$YPos – addTextWrap_$lineheight. WARNING_2: This addTextWrap_$lineheight = addTextWrap_$fontsize is the difference in y_pos between addTextWrap() and AddText(). OPTIONAL, but I recommend to use it. To change font size, you have to use public function SetFontSize() in tcpdf/tcpdf.php. Example: $this->SetFontSize($size); $this->MultiCell($linewidth, $fontsize, html_entity_decode($text, ENT_QUOTES, 'UTF-8'), $border, $Align, $fill, 1, $XPos, $this->h - $Ypos);// Using $Ypos as in AddText(). // return $this->h - $this->y;// The position after printing. COMMENT: $YPos is the same as in addText(). More info: In tcpdf/tcpdf.php, line 5732. See also: SetFont(), SetDrawColor(), SetFillColor(), SetTextColor(), SetLineWidth(), Cell(), Write(), SetAutoPageBreak(). Comments -------------- * For a quick transition, I included a new function in includes/class.pdf: //------------------------------------------------------------------------------ public function TextWrap($XPos, $YPos, $linewidth, $fontsize, $text, $Align='left', $border=0, $fill=false) { // Adds text to the page, but ensure that it fits within a certain width. If it does not fit then put in as much as possible, splitting at white space or soft hyphen character and return the remainder. Justification can also be specified for the text. It use UTF-8 encoding. // $XPos = Cell horizontal coordinate from page left side to cell left side in dpi (72dpi = 25.4mm). // $YPos = Cell vertical coordinate from page bottom side to cell top side in dpi (72dpi = 25.4mm). // $linewidth = Cell (line) width in dpi (72dpi = 25.4mm). If 0, MultiCell() extends up to the right margin of the page. // $fontsize = Font size in dpi (72dpi = 25.4mm). // $text = Text to be split in portion to be add to the page and the remainder to be returned. // $Align = 'left', 'center', 'centre', 'full' or 'right'. // $border = Indicates if borders must be drawn around the cell. The value can be a number: 0: no border (default), 1: frame, or a string containing some or all of the following characters (in any order): L: left, T: top, R: right, B: bottom or an array of line styles for each border group - for example: array('LTRB' => array('width' => 2, 'cap' => 'butt', 'join' => 'miter', 'dash' => 0, 'color' => array(0, 0, 0))). // $fill = Indicates if the cell background must be painted (true) or transparent (false). // @access public. $this->SetFontSize($fontsize);// Public function SetFontSize() in ~/includes/tcpdf/tcpdf.php. $text = html_entity_decode($text, ENT_QUOTES, 'UTF-8');// Convert all HTML entities to their applicable characters. switch($Align) {// Translate from Pdf-Creator to TCPDF. case 'left': $Align = 'L'; break; case 'right': $Align = 'R'; break; case 'center': $Align = 'C'; break; case 'centre': $Align = 'C'; break; case 'full': $Align = 'J'; break; default: $Align = 'L'; break; } $this->MultiCell($linewidth, $fontsize, $text, $border, $Align, $fill, 1, $XPos, $this->h - $YPos);// Public function SetFontSize() in ~/includes/tcpdf/tcpdf.php. return $this->h - $this->y;// COMMENT: $YPos is the same as in addText(). } //------------------------------------------------------------------------------ * Note: I am also thinking in migrate from barcodepack to Nicola Asuni TCPDF' barcode_functions.
