如何在imagemagick中自动换行

我能够计算出像这样的基本自动换行功能

 $draw = new ImagickDraw();
 $x = 0;
 $y=20;
 $angle = 0;
 $str = "some text for testing of a word wrap in imagemagick";
$str = wordwrap($str, 10,"\r");
$im->annotateImage( $draw, $x, $y, $angle, $str );

，并且似乎工作正常，除了跟踪我认为它称为“你知道行之间的空间太大，以及关于如何解决此问题的想法或想法，或者是否有更好的方法”选项

I was able to figure a basic word wrap function like this

 $draw = new ImagickDraw();
 $x = 0;
 $y=20;
 $angle = 0;
 $str = "some text for testing of a word wrap in imagemagick";
$str = wordwrap($str, 10,"\r");
$im->annotateImage( $draw, $x, $y, $angle, $str );

and that seems to work ok except that the tracking i think its called you know the space between lines is too much and thoughts or ideas on how to fix this or if there is a better option

行高由字体规格决定。您当然可以添加一个空行，否则您需要一次渲染一行并手动指定图像中文本的偏移量。

[编辑]：根据OP请求，似乎有一个命令行版本。

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;
}

Some refactoring:

$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;
}

正弦我可以控制渲染每条线的间距

  $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 );
  }

Sine I could control the spacing I went with rendering the lines each

  $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 );
  }
