使用imagemagick显示fontawesome的编码错误 [英] encoding error displaying fontawesome with imagemagick

问题描述

我正在尝试使用fontawesome和imagemagick将它的角色显示为png，
这里是我的代码：

i'm trying to use fontawesome with imagemagick to display it's character as png ,
here is my code:

$size = '50';
$text = '';
$imgW = 200;
$imgH = 200;
$font = 'fontawesome-webfont.ttf';
$image = new Imagick();
$image->setResolution(144,144);
$draw = new ImagickDraw();
$draw->setFont($font);
$draw->setFontSize($size);
//$draw->setTextEncoding('UTF-8');
//$draw->setStrokeAntialias(true);
//$draw->setTextAntialias(true);
$image->newImage($imgW, $imgH, new ImagickPixel('none'));
$image->annotateImage($draw, 10, 45, 0, $text);
$image->setImageFormat('png');
header('Content-type: image/png');
echo $image;

但图像输出看起来像这样

but the image output looks like this

任何想法如何修复这样的编码问题？

any idea how to fix such a encoding problem?

推荐答案

使用这个答案以确保我有一个UTF-8字符串被传递到ImageMagick为我工作。代码中唯一的变化是第二行：

Using the example from this answer to ensure I had a UTF-8 string being passed into ImageMagick works for me. The only change from your code is the second line:

$size = '50';
$text = html_entity_decode("", ENT_COMPAT, 'UTF-8');
$imgW = 200;
$imgH = 200;
$font = 'fontawesome-webfont.ttf';
$image = new Imagick();
$image->setResolution(144,144);
$draw = new ImagickDraw();
$draw->setFont($font);
$draw->setFontSize($size);
//$draw->setTextEncoding('UTF-8');
//$draw->setStrokeAntialias(true);
//$draw->setTextAntialias(true);
$image->newImage($imgW, $imgH, new ImagickPixel('none'));
$image->annotateImage($draw, 10, 45, 0, $text);
$image->setImageFormat('png');
header('Content-type: image/png');
echo $image;
