ImageMagick convert命令委托错误

Question

在linux上执行以下convert命令时，字体出现委托错误。

convert -font /usr/share/fonts/type1/gsfonts/n021003l.pfb -pointsize 48 -size 
400 caption:ABC text.png 

转换：委托库支持不内置'/usr/share/fonts/type1/gsfonts/n021003l.pfb'（Freetype）@警告/注释. c/RenderFreetype/1818。转换：没有此图像格式的解码委托PNG错误/成分. c/ReadImage/509。转换：委托库支持不内置'/usr/share/fonts/type1/gsfonts/n021003l.pfb'（Freetype）@警告/注释. c/RenderFreetype/1818。转换：没有此图像格式的解码委托PNG'@错误/成分. c/ReadImage/509。转换：没有图像定义'text.png'@错误/转换. c/ConvertImageCommand/3254。

下面是我运行命令“convert-list configure”时的输出

当尝试运行“identify-list font”命令时，它支持此处convert命令中使用的字体。

Font: Times-Roman
family: Times
style: Normal
stretch: Normal
weight: 400
glyphs: /usr/share/fonts/type1/gsfonts/n021003l.pfb

感谢您的帮助。谢谢

问题是该字体是freetype字体，并且您尚未安装freetype代理-它未列在您的“识别-列表配置”中的“代理”下，或者如果您运行的是“识别-版本”。您需要安装它。
