如何在ImageMagick中包装文本

行高由字体度量确定。当然,您可以添加一个空行,否则您将需要一次呈现一行,并手动指定图像中文本的偏移量。

[编辑] :在OP请求时,似乎有一个 command-line version of it .

我可以控制绘制每一行所用的间距。

  $draw = new ImagickDraw();
  $x = 0;
  $y=20;
  $angle = 0;
  $padding = 10;
  $str = "some text for testing of a word wrap in imagemagick";
  $str = wordwrap($str, 10,"\r");
  $str_array = explode("\n",$str);
  foreach($str_array as $line)
    $im->annotateImage( $draw, $x, $y+$padding, $angle, $line );
  }

您可以让ImageMagic为您计算度量详细信息: http://php.net/manual/en/function.imagick-queryfontmetrics.php .

一些重构:

$string = 'Some random Text here';

$y = 120;
$line_height = 50;
$str = wordwrap($string, 20,"\n");
$str_array = explode("\n",$str);
foreach($str_array as $line){
    $image->annotateImage($draw, 0, $y, 0, $line );
    $y += $line_height;
}
