为什么fontmagick的字体列表为空？

Question

我正在尝试使用ImageMagick向图像添加一些文本.但我发现它总是说我的指定字体不存在.仔细阅读本手册之后我注意到我可以convert -list font用来输出所有可用的字体,但在尝试之后我发现可用字体列表是空的.

这就是我得到的:

shell$ convert -list font
shell$ 

感谢您提供任何建议.

我只是设法告诉ImageMagick我的OSX系统上的字体是这样的:

# Make a new directory for ImageMagick local settings and cd into it
mkdir ~/.magick
cd ~/.magick

# Grab script to find all fonts on system and store them in a config file
curl http://www.imagemagick.org/Usage/scripts/imagick_type_gen > type_gen

# Run script, telling it where my fonts are and create "type.xml" file with list  
find /System/Library/Fonts /Library/Fonts ~/Library/Fonts -name "*.[to]tf" | perl type_gen -f - > type.xml

# Go to ImageMagick config folder - see note at end to find correct folder
cd /usr/local/Cellar/imagemagick/6.8.9-1/etc/ImageMagick-6

# Edit system config file called "type.xml" and add line near end to tell IM to look at local file we made in earlier step
<typemap>
<include file="type-ghostscript.xml" />
<include file="~/.magick/type.xml" />                       ### THIS LINE ADDED ### 
</typemap>

如何为您的type.xml文件找到正确的文件夹

type.xml存储的文件夹在系统和版本之间可能有很大差异.我知道找到它的最好方法是运行以下命令来查看ImageMagick的外观:

convert -debug configure -list font 2>&1 | grep -E "Searching|Loading"

  Searching for configure file: "/usr/local/Cellar/imagemagick/6.9.5-0/share/ImageMagick-6/type.xml"
  Searching for configure file: "/usr/local/Cellar/imagemagick/6.9.5-0/lib/ImageMagick//config-Q16/type.xml"
  Searching for configure file: "/usr/local/Cellar/imagemagick/6.9.5-0/etc/ImageMagick-6/type.xml"
  Searching for configure file: "/usr/local/Cellar/imagemagick/6.9.5-0/share/doc/ImageMagick-6/type.xml"
  Searching for configure file: "/Users/mark/.config/ImageMagick/type.xml"
  Searching for configure file: "/Users/mark/.magick/type.xml"
  Loading type configure file "/usr/local/Cellar/imagemagick/6.9.5-0/etc/ImageMagick-6/type.xml" ...
  Loading type configure file "/usr/local/Cellar/imagemagick/6.9.5-0/etc/ImageMagick-6/type-apple.xml" ...
  Loading type configure file "/usr/local/Cellar/imagemagick/6.9.5-0/etc/ImageMagick-6/type-ghostscript.xml" ...
  Loading type configure file "/Users/mark/.magick/type.xml" ...

所以有很多地方可以插入字体.通常,如果您选择以文件夹开头的文件夹,/etc或者/usr/local字体将可供所有用户和Web服务器中的脚本使用 - 如果您需要.另一方面,如果您只是一个用户,您可能更喜欢将字体配置文件保留在登录目录中,例如$HOME/.magick/type.xml.

使用 MacOs Catalina 上的 ImageMagic 7.0.10，我完成了以下操作。

• 编辑/usr/local/Cellar/imagemagick/7.0.10-7/etc/ImageMagick-7/type.xml并替换type-ghostscript为type-apple
• /usr/local/Cellar/imagemagick/7.0.10-7/etc/ImageMagick-7/type-apple.xml在所有字形路径前编辑并添加了“/System/Library/Fonts/Supplemental”
