respecting bbox? (and BDF to TTF converter)

[roytam1]

I'm finding a way that can respecting bbox since fontforge will trim the bitmap.

bdftottf.py:

try:
    from PIL.BdfFontFile import *
except ImportError:
    from BdfFontFile import *

class BdfFontFileUnicode(FontFile.FontFile):

    def __init__(self, fp):

        FontFile.FontFile.__init__(self)

        s = fp.readline()
        if s[:13] != "STARTFONT 2.1":
            raise SyntaxError, "not a valid BDF file"

        props = {}
        comments = []

        while 1:
            s = fp.readline()
            if not s or s[:13] == "ENDPROPERTIES":
                break
            i = string.find(s, " ")
            props[s[:i]] = s[i+1:-1]
            if s[:i] in ["COMMENT", "COPYRIGHT"]:
                if string.find(s, "LogicalFontDescription") < 0:
                    comments.append(s[i+1:-1])

        font = string.split(props["FONT"], "-")

        font[4] = bdf_slant[string.upper(font[4])]
        font[11] = bdf_spacing[string.upper(font[11])]

        ascent = int(props["FONT_ASCENT"])
        descent = int(props["FONT_DESCENT"])

        fontname = string.join(font[1:], ";")

        # print "#", fontname
        # for i in comments:
        #       print "#", i

        self.glyph = {}

        font = []
        while 1:
            c = bdf_char(fp)
            if not c:
                break
            id, ch, (xy, dst, src), im = c
            if ch >= 0: # and ch < len(self.glyph):
                self.glyph[ch] = xy, dst, src, im

if __name__ == '__main__':
    import sys
    from convert import convert
    for filename in sys.argv[1:]:
        p = BdfFontFileUnicode(file(filename))
        glyphmap = {}
        for k,v in p.glyph.iteritems():
            print k,v
            glyphmap[k] = v[3]
        convert(glyphmap, filename[:-4])
