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 ); } }
