我知道我已经安装了这种字体，当我列出ImageMagick可以看到的所有点时，它就会显示出来，但是无论我将这段代码中的字体更改为什么，字体都不会在实际渲染的图像中改变：
convert new-again.png -size 1800x420 -font Din-Condensed-Bold
-pointsize 84 -background 'transparent' -fill black -gravity center
caption:'Faerie Dragons love hot apple pies and also cold apple pies!'
-gravity south -composite background1.png
例如，我尝试过使用其他字体名称，例如Corsiva，并且它不会改变。
这是我的版本信息：
