I should finish with this class within a couple of weeks, but thought some people could get some use out of it... mainly getTextyPos, which I will also add a much more simple set of function calls... **********************************************************************************/ /* these functions are made to work for text that has an angle of 0 when i have time someday i'll change it to work with angles as well... */ var $defont; var $defontSize; var $deangle; var $destring; function TriImageClass() // constructor { $this->defont = "fonts/times.ttf"; $this->defontSize = 24; $this->deangle = 0; $this->destring = "Test"; } /* function getImageWidth(...) returns the total width that a true type font box requires */ function getTextWidth($font = -1, $fontSize = -1, $angle = -1, $string = -1) { if ($font == -1) { $font = $this->defont;} if ($fontSize == -1) { $fontSize = $this->defontSize;} if ($angle == -1) { $angle = $this->deangle;} if ($string == -1) { $string = $this->destring;} $imSize = ImageTTFBBox($fontSize,$angle,$font,$string); $totalWidth = abs($imSize[4]-$imSize[0]); return $totalWidth; } // function getImageWidth /* function getTextHeight(...) returns the total height that a true type font box requires */ function getTextHeight($font = -1, $fontSize = -1, $angle = -1, $string = -1) { if ($font == -1) { $font = $this->defont;} if ($fontSize == -1) { $fontSize = $this->defontSize;} if ($angle == -1) { $angle = $this->deangle;} if ($string == -1) { $string = $this->destring;} $imSize = ImageTTFBBox($fontSize,$angle,$font,$string); $upper = $imSize[5]; $lower = $imSize[1]; $totalHeight = abs($lower+$upper); return $totalHeight; } /* function getTextxPos(...) returns the approximate x position to use (to center) the text box. */ function getTextxPos($im = 0, $width = 0) { return abs(imagesx($im)-$width)/2; } // function getTextxPos /* function getTextyPos(...) returns the approximate y position to use (to center) for the actual text box. works well for multi-line messages with the ttf fonts I use */ function getTextyPos($im = 0, $height = 0) { return abs((imagesy($im) - $height))/2; } // function getTextyPos } // class TriImageClass } ?>
