imagemagick - 无法通过 ImageMagick 使用已安装的字体

Question

我使用的是 OS X 10.10.3 并使用 Homebrew 安装了 ImageMagick。

我正在尝试使用 ImageMagick 创建动态图像生成脚本，但收到与字体相关的错误消息。这是我使用的命令，它是取自 ImageMagick 的字体效果页面的示例。我该怎么做才能通过 ImageMagick 使用我的机器上安装的字体？字体为 TrueType 或 PostScript。

convert -size 320x100 xc:lightblue -font Arial -pointsize 72 \
-fill navy -annotate +25+65 'Anthony' \
-distort Arc 120  -trim +repage \
-bordercolor lightblue -border 10  /outputdirectory/font_arc.jpg

这是它返回的错误消息。

convert: delegate library support not built-in `/Library/Fonts/Arial.ttf' (Freetype) @ warning/annotate.c/RenderFreetype/1560.

下面是我运行命令“convert -list configure”时的输出

最后，这是“brew info imagemagick”的结果。

除上述内容外，这里是 TrueType 和 PostScript 字体的“identify -list format”的结果。

PFA* TTF       r--   Postscript Type 1 font (ASCII) (Freetype 2.5.5)
