Python/Tk Postscript の日本語フォントの問題

2012/04/07
2012/04/15 修正

目標

Python/Tk の Canvas に日本語文字を含む場合も postscript 関数で EPS ファイルに落とせるようにする。ここでは Python には ver.3.2.2、Tcl/Tk には ver.8.6b2 を使った。日本語文字を扱えるためには Tcl/Tk にパッチを当てる必要がある。そのために、Python も、Tcl/Tk もソースを取り寄せ、コンパイルしなくてはならない。

インストール目標:


framework
aqua
-arch i386 -arch x86_64

実現目標:


Python/Tk Canvas postscript
Japanese font Hiragino

Tcl/Tk ver.8.6b2

src=$HOME/src		# my case
tcl=$srcdir/tcl8.6b2
tk=$srcdir/tk8.6b2
rm -rf $src/build	# if exists

$tcl/macosx および $tk/macosx の中には Makefile と GNUmakefile が含まれている。Mac/OSX の make は実際には gnumake なので、ファイルを指定しない場合には GNUmakefile が使われる。そして、README には GNUmakefile の使用が推奨されている。しかし、以下では Makefile を使う。理由は、GNUmakefile を思うように操るのが困難だったからである。

Tcl の compile

cd $tcl.macosx
export CFLAGS="-arch i386 -arch x86_64"
./configure --enable-framework
make -f Makefile

Tk postscript の修正
2012/04/15 修正

Tcl/Tk の postscript コマンドで日本語文字が扱えるようにするためには、次の修正を行えば良い。もっと良い方法もあろうが、取りあえず、この方法で何とかなる。

mkpsenc.tcl の修正

    ps function ISOEncode {dup /CMap known {} {ISOEncode1} ifelse }

    ps function ISOEncode1 {
	dup length dict begin
	{1 index /FID ne {def} {pop pop} ifelse} forall
	/Encoding CurrentEncoding def
	currentdict
	end
	% I'm not sure why it's necessary to use "definefont" on this new
	% font, but it seems to be important; just use the name "Temporary"
	% for the font.
	/Temporary exch definefont
    }



$tk/library/mkpsenc.tcl




これで、ISOEncodeが、CMAP に対しては無効になる。

tkFont.c の修正

a.eps のヘッダ



-bash$ ps2pdf -dEPSCrop a.eps
-bash$ gs a.pdf
-bash$ open -a "/Applications/Adobe Reader 9/Adobe Reader.app" a.pdf






gs(左)とadobe reader(右) で見た、a.pdf



Mac/OSX の Preview.app で開くと、Preview.app が潰れる! (潰れるのは Preview.app のバグ)

注意
gs の設定が必要。詳しくは「Gostscript の日本語フォントの問題」を見よ。

問題点
2012/04/15 修正

もっと、良い方法があるだろう。OSAKA フォントに関して問題があるかも知れない。

Python/Tk postscript の Font Map

ついでに a.py の フォントマップ版を作ろう。この考え方は役に立つ場面があるかも知れない。


#encoding: utf-8
from tkinter import *
FONT1="Times 30 italic"
FONT2="HiraginoKakuGothicPro 30 bold"
tk=Tk()
c=Canvas(tk,width=300,height=200)
c.pack(fill="both",expand=1)

c.create_text(150,80,text="ABC",font=FONT1)
c.create_text(150,120,text="いろは",font=FONT2)
c.create_rectangle(100,50,200,150,outline="green")

tk.call("set","fmap(%s)"%FONT1,"Helvetica 30")
tk.call("set","fmap(%s)"%FONT2,"HiraKakuPro-W6 30")

def cmd():
  c.postscript(file="b.eps",fontmap="fmap")
  tk.destroy()
dir(tk)
b=Button(tk,text="終了", command=cmd)
b.pack()
tk.mainloop()


Python/Tk の Canvas postscript fontmap の使い方



どうやらフォント名は文字列でないとダメらしい。

fmap のところは、普通は fontmap と書くところであるが、postscript オプションの fontmap と紛らわしいので、このプログラムでは敢えて fmap とした。他の名前で構わない。

Python は、どの Tk と結び付くか?
Tk は Python が利用する Tk のダイナミックライブラリ(dylib)である。システム上に多数ある Tk のどれとリンクするのか?

$py/setup.py

がコンパイル時に実行される。


    def detect_tkinter_darwin(self, inc_dirs, lib_dirs):
        # The _tkinter module, using frameworks. Since frameworks are quite
        # different the UNIX search logic is not sharable.
        from os.path import join, exists
        framework_dirs = [
            '/Library/Frameworks',
            '/System/Library/Frameworks/',
            join(os.getenv('HOME'), '/Library/Frameworks')
        ]


$py/setup.pyの一部


これを見ると、


/Library/Frameworks
/System/Library/Frameworks
$HOME/Library/Frameworks


の順で、Tk.framework/Tk を探すことが分かる。
