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

2017-06-07 - ⧖ 5.0 min

Environment

  • 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 {
        InitializeMagick(*argv);
        Color bg_color = Color("red");

        Image image("1000x1000", bg_color);

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

        drawList.push_back(DrawablePointSize(200));
        drawList.push_back(DrawableFont("Microsoft Sans Serif", AnyStyle, 400, AnyStretch));
        //drawList.push_back(DrawableFont("/Library/Fonts/Arial.ttf")); // no problem
        drawList.push_back(DrawableText(10,150,"hello"));
        drawList.push_back(DrawableFont("Arial", AnyStyle, 400, AnyStretch));
        drawList.push_back(DrawableText(10,500,"hello"));

        image.draw(drawList);
        image.write("out.jpg");
    }
    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
Caught exception : Magick: Unable to read font (/usr/local/share/ghostscript/fonts/n019003l.pfb) reported by magick/annotate.c:1063 (RenderFreetype)

Solution

setup to type.mgk file.

script of generate type.mgk from system_profiler's font list (mgkgen.py)

setup sequence

$ system_profiler -xml SPFontsDataType > fontset.xml
$ python3 mgkgen.py fontset.xml > type.mgk
# backup if you need
$ cp /usr/local/Cellar/graphicsmagick/1.3.25/lib/GraphicsMagick/config/type.mgk /usr/local/Cellar/graphicsmagick/1.3.25/lib/GraphicsMagick/config/type.mgk.bk
$ cp type.mgk /usr/local/Cellar/graphicsmagick/1.3.25/lib/GraphicsMagick/config/type.mgk

check font list

$ gm convert -list font
