php使用Imagick生成图片的方法

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 );
  }
}
