$ convert -size 320x85 xc:transparent -font Bookman-DemiItalic -pointsize 72 -draw "text 25,60 'Magick'" -channel RGBA -blur 0x6 -fill darkred -stroke magenta -draw "text 20,55 'Magick'" output.png

convert: unable to read font `Bookman-DemiItalic' @ warning/annotate.c/RenderType/807.

I think I have a better idea of what is happening: if I use one of the
fonts listed by

~ convert -list font

I get no error, and the output looks fine. Looking closer, I find that
there are several fonts missing from the newer version of imagemagick,
namely, the postscript fonts:

I think I've understood the problem: when a font isn't found,
imagemagick falls back onto using helvetica (line 1032 of
magick/annotate.c). On the older imagemagick, as the postscript fonts
were automatically included with

<typemap>
@type_include_files@
</typemap>

there was no problems. On the newer version, Helvetica is missing, so it
isn't found at all. That's pretty bad for the default font !

I don't know who's to blame: how comes helvetica doesn't show up in
fontconfig ? gs-fonts are installed, which is where it should be coming,
shouldn't it ?

• if (type_info == (const TypeInfo *) NULL)
  type_info=GetTypeInfoByFamily("Utopia",draw_info->style,
  draw_info->stretch,draw_info->weight,&image->exception);

• if (type_info == (const TypeInfo *) NULL)
  type_info=GetTypeInfoByFamily("arial",draw_info->style,
  draw_info->stretch,draw_info->weight,&image->exception);

I've just built and installed a set of local imagemagick packages with
the suggested patch from upstream (adding "Utopia" as an alternative
font family) and I'm afraid I have to report that I still get the same
problem:

$ montage IMG_3058.jpg IMG_3059.jpg
montage: unable to read font `(null)' @ error/annotate.c/RenderFreetype/1047.

(the change in line number being purely the addition of the patch).

Argh ! I was just writing up a long mail explaining that, in part.
I'll send it along in a few minutes.

The thing is that the font "helvetica" doesn't exist as such for
fontconfig, but through something like a matching mechanism:

~ fc-match helvetica
n019003l.pfb: "Nimbus Sans L" "Regular"

The *real* font behind is Nimbus-Sans (in my case, but see the mail
I'll send in a minute).

To do well, on would have to use the equivalent of fc-match somewhere
around the place where imagemagick falls back onto Helvetica as default.
I don't have any idea of how to do that, but I'm pretty sure upstream would.
