本篇章节讲解php实现生成code128条形码的方法。分享给大家供大家参考,具体如下: 效果图: self::STARTA,'B'=>self::STARTB,'C'=>self::STARTC); private $code =''; private $bin_code =''; private $text =''; public function __construct($code='',$text='',$type='B') { if (in_array($type,array('A','B','C'))) $this->setType($type); else $this->setType('B'); if ($code !=='') $this->setCode($code); if ($text !=='') $this->setText($text); } public function setUnitWidth($unit_width) { $this->unit_width = $unit_width; $this->quiet_zone = $this->unit_width*6; $this->font_height = $this->unit_width*15; if (!$this->is_set_height) { $this->heith = $this->unit_width*35; } } public function setFontType($font_type) { $this->font_type = $font_type; } public function setBgcolor($bgcoloe) { $this->bgcolor = $bgcoloe; } public function setColor($color) { $this->color = $color; } public function setCode($code) { if ($code !='') { $this->code= $code; if ($this->text ==='') $this->text = $code; } } public function setText($text) { $this->text = $text; } public function setType($type) { $this->type = $type; } public function setHeight($height) { $this->height = $height; $this->is_set_height = true; } private function getValueFromChar($ch) { $val = ord($ch); try { if ($this->type =='A') { if ($val > 95) throw new Exception(' illegal barcode character '.$ch.' for code128A in '.__FILE__.' on line '.__LINE__); if ($val < 32) $val += 64; else $val -=32; } elseif ($this->type =='B') { if ($val < 32 || $val > 127) throw new Exception(' illegal barcode character '.$ch.' for code128B in '.__FILE__.' on line '.__LINE__); else $val -=32; } else { if (!is_numeric($ch) || (int)$ch < 0 || (int)($ch) > 99) throw new Exception(' illegal barcode character '.$ch.' for code128C in '.__FILE__.' on line '.__LINE__); else { if (strlen($ch) ==1) $ch .='0'; $val = (int)($ch); } } } catch(Exception $ex) { errorlog('die',$ex->getMessage()); } return $val; } private function parseCode() { $this->type=='C'?$step=2:$step=1; $val_sum = $this->start_codes[$this->type]; $this->width = 35; $this->bin_code = $this->codes[$val_sum]; for($i =0;$i附加一个强大的条码生成扩展包: http://www.barcodebakery.com/ PS:这里再为大家推荐一款相似的条形码生成工具供大家参考使用: 在线条形码(一维码)生成/实时预览工具: 更多关于PHP相关内容感兴趣的读者可查看本站专题:《》、《》、《》、《》、《》、《》及《》 希望本文所述对大家PHP程序设计有所帮助。 (编辑:ASP站长网) |
