Magick++ (GraphicsMagick) problems when using drawing text with DrawableFont() on macOS


  • MacOSX 10.11.6
  • GraphicsMagick 1.3.25 (installing with Homebrew)

If you get error when you specify "Arial" or "Microsoft Sans Serif" to font family. For example as following code:

 // drawfont.cpp
 #include <iostream>
 #include <Magick++.h>

 using namespace Magick;
 using namespace std;

 int main(int argc, char **argv)
     try {
         Color bg_color = Color("red");

         Image image("1000x1000", bg_color);

         std::list<Magick::Drawable> drawList;

         drawList.push_back(DrawableFont("Microsoft Sans Serif", AnyStyle, 400, AnyStretch));
         //drawList.push_back(DrawableFont("/Library/Fonts/Arial.ttf"));     // no problem
         drawList.push_back(DrawableFont("Arial", AnyStyle, 400, AnyStretch));

     catch(exception & error_)
         cout<<"Caught exception : " << error_.what() << endl;

Error Message

I get the following error

 $ clang++ -std=c++11 -L/usr/local/lib -lGraphicsMagick++ -I/usr/local/include/GraphicsMagick -o drawfont drawfont.cpp
 $ ./drawfont
