本文实例讲述了php使用Imagick生成图片的方法。分享给大家供大家参考。具体如下:
这里使用Imagick 生成图片
解决了图片写中文文字乱码问题,添加支持的字体
public function getPic(){ header(\'Content-Type: text/html; charset=utf-8\'); $text = \'中粮屯河(sh600737)\';//中粮屯河(sh600737) $watermark = \'305988103123zczcxzas\'; $len = strlen($text); $width = 10.5*(($len-8)/3*2+8); $height = 26; $imagick = new Imagick(); $color_transparent = new ImagickPixel(\'#ffffff\'); //transparent 透明色 $imagick->newImage($width, $height, $color_transparent, \'jpg\'); //$imagick->borderimage(\'#000000\', 1, 1); $style[\'font_size\'] = 12; $style[\'fill_color\'] = \'#000000\'; for($num= strlen($watermark); $num>=0; $num--){ $this->add_text($imagick,substr($watermark, $num,1), 2+($num*8), 30, 1,$style); $this->add_text($imagick,substr($watermark, $num,1), 2+($num*8), 5, 1,$style); } //return; $style[\'font_size\'] = 20; $style[\'fill_color\'] = \'#FF0000\'; $style[\'font\'] = \'./msyh.ttf\'; ///微软雅黑字体 解决中文乱码 //$text=mb_convert_encoding($text,\'UTF-8\'); //iconv(\"GBK\",\"UTF-8//IGNORE\",$text); $this->add_text($imagick,$text, 2, 20, 0,$style); header ( \'Content-type: \' . strtolower ($imagick->getImageFormat ()) ); echo $imagick->getImagesBlob (); } // 添加水印文字 public function add_text(& $imagick, $text, $x = 0, $y = 0, $angle = 0, $style = array()) { $draw = new ImagickDraw (); if (isset ( $style [\'font\'] )) $draw->setFont ( $style [\'font\'] ); if (isset ( $style [\'font_size\'] )) $draw->setFontSize ( $style [\'font_size\'] ); if (isset ( $style [\'fill_color\'] )) $draw->setFillColor ( $style [\'fill_color\'] ); if (isset ( $style [\'under_color\'] )) $draw->setTextUnderColor ( $style [\'under_color\'] ); if (isset ( $style [\'font_family\'] )) $draw->setfontfamily( $style [\'font_family\'] ); if (isset ( $style [\'font\'] )) $draw->setfont($style [\'font\'] ); $draw->settextencoding(\'UTF-8\'); if (strtolower ($imagick->getImageFormat ()) == \'gif\') { foreach ( $imagick as $frame ) { $frame->annotateImage ( $draw, $x, $y, $angle, $text ); } } else { $imagick->annotateImage ( $draw, $x, $y, $angle, $text ); } }
希望本文所述对大家的php程序设计有所帮助。
