中文点阵字库的python自动生成程序前些时间把python里关于中文编码的问题摆弄了一把，辅以wxPython,写成了这个点阵字库生成软件，对搞嵌入式系统的朋友应该挺有用的。程序能生成8-32点宽的gb2312,gbk,big5三种中文字库，和标准的ascii字库；字体可以是任意的系统支持字体，但必须是等宽字体。 这是我第一个真正有意义的实用python程序，从中你也可以看到python的强大，整个代码300行不到！ 代码和有关中文几种编码的资料的打包在这里： http://blogimg.chinaunix.net/blog/upfile/070804153307.zip 这里似乎不支持过长的代码粘贴：只好把它变成text了： 源代码： #-*- coding: gb2312 -*- #---------------------------------------------------------------------- #pixel Chinese font library generator for embed system #function : this program is to genreate chinese char library for embed system # in encoding with gb2312 ,gbk, or Big5, in any font type user like and system have. # it can also generate Ascii librarys, the char height and width is allways 2:1 #version : 0.1 #author :vinge #start date :20070803 #license: GPL3 #---------------------------------------------------------------------- #Notice: #for gb2312 chars start form 0xB0A1 ths chars form 0xA0A1 to 0xAFFE is not included #for gbk,and big5, there are so many while holes start form 0xa1,thought they didn't # mean any chars, it was also fill with empty 0x00, so as to keep the library linear #---------------------------------------------------------------------- import wx import binascii #import wx._gdi ID_ENCODE=wx.NewId() ID_FONT=wx.NewId() ID_HEIGHT=wx.NewId() ID_WEIGHT=wx.NewId() ID_ENCODE=wx.NewId() class MyFrame(wx.Frame): """ This is the main frame of program """ def __init__(self, parent, title): wx.Frame.__init__(self, parent, -1, title, pos=(150, 150), size=(400, 250)) #global self.dc,self.screen self.charheight=16 self.charwidth=8 self.specwidth=16 self.chrlist=[] self.chrpixellist=[] self.fontName="System" self.encode="ASCII" self.height=16 self.weight=wx.NORMAL self.font=wx.Font(self.height*0.75, wx.SWISS , wx.NORMAL, self.weight, faceName=self.fontName) self.buffer = wx.EmptyBitmap(320,240) self.dc = wx.BufferedDC(None,self.buffer)#wx.Size(300,200)) self.dc.SetPen(wx.Pen("WHITE", 1)) self.dc.SetBackground(wx.Brush((0,0,0,255),wx.SOLID)) self.dc.SetTextBackground((255,255,255,255)) self.dc.SetTextForeground((255,255,255,255)) #self.dc.SetFont(wx.Font(16, wx.SWISS , wx.NORMAL, wx.NORMAL)) self.dc.SetFont(self.font ) #
