Converting Tewi.bdf to ttf

Hello, I'm having some troubles understanding on how this works. I have a font called Tewi in bdf format. I'd like to convert it to ttf. I used convert.py tewi.bdf and its output was outliner.pyc. I've tried doing outliner.py outliner.pyc and outliner.py tewi.bdf and I get IOError: cannot identify image file 'outliner.pyc (or tewi.bdf)'

What am I doing wrong? Do I need to use Font Forge in some way? Thanks.

Hi,
I got the exception when would like to run pcftottf, log as below:

respecting bbox? (and BDF to TTF converter)

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])

Space character width

I'm trying to convert the Tamsyn 8x15 font (or its derivative Tamzen) for use with Sublime Text, but the resulting TTF has the space character come out the wrong size. Hard tabs line up correctly with the text, but single spaces do not:

I'm not sure whether this is a bug in the font definition, in bitmap2ttf, or in Sublime Text. Other editors don't seem to have this bug, using the same TTF file. Does anybody know how to fix it?

Edit: all metrics returned from self._load_metrics() are the same exact tuple (8, 15, 0, 8, 8, 12, 3, 0) and all SetWidth(%d) generated by convert.py have the same width (533). I really can't see what's causing this issue.

How to use please ?

Clearly confirm that there is already "import convert"
But it shows "no model convert"

I want to convert .bmp to ttf
Can anyone help me?

Bitsnpicas works better for all use cases

Spent a lot of time trying to use bitmap2ttf and just couldn't get it to work for my application. This package from kreativekorp works really well out of the box. It accepts fontforge files.

Just in case you are struggling like I was, this is a better option. But still - thanks @ali1234 for all your hard work.

ValueError: not enough image data

Just wanted to start by thanking you for making this. Very cool utility.

I've successfully used this to convert a .pcf font from gohufont into a ttf.

However I am now trying to convert from a fontforge file New York.sfd into a non bitmapped ttf.

My workflow is to save out a .bdf from the .sfd. I then use bdftopcf to convert the bdf file into pcf.

Unfortunately, there is something wrong with the resulting pcf. I can open it with fontforge and view all the glyphs - everything looks fine. But I get this error when running your script.

Traceback (most recent call last):
  File "pcftottf.py", line 88, in <module>
    p = PcfFontFileUnicode(file(filename))
  File "pcftottf.py", line 38, in __init__
    bitmaps = self._load_bitmaps(metrics)
  File "/usr/local/lib/python2.7/site-packages/PIL/PcfFontFile.py", line 225, in _load_bitmaps
    Image.frombytes("1", (x, y), data[b:e], "raw", mode, pad(x))
  File "/usr/local/lib/python2.7/site-packages/PIL/Image.py", line 2100, in frombytes
    im.frombytes(data, decoder_name, args)
  File "/usr/local/lib/python2.7/site-packages/PIL/Image.py", line 742, in frombytes
    raise ValueError("not enough image data")
ValueError: not enough image data

Any idea what is going on here? I have no clue where to start writing my own loader, so any tips on converting the type would be greatly appreciated.

thanks!

PIL ValueError: tile cannot extend outside image

Hello. Your project is awesome and I was amazed that it actually works.

I am trying to convert artwiz fonts (which are in pcf format) to ttf, and for some of them it shows the error in the title.
Trace is this:

 Traceback (most recent call last):
  File "./pcftottf.py", line 88, in <module>
    p = PcfFontFileUnicode(file(filename))
  File "./pcftottf.py", line 38, in __init__
    bitmaps = self._load_bitmaps(metrics)
  File "/usr/lib64/python2.7/site-packages/PIL/PcfFontFile.py", line 223, in _load_bitmaps
    Image.frombytes("1", (x, y), data[b:e], "raw", mode, pad(x))
  File "/usr/lib64/python2.7/site-packages/PIL/Image.py", line 1825, in frombytes

  File "/usr/lib64/python2.7/site-packages/PIL/Image.py", line 601, in frombytes
    d.setimage(self.im)
ValueError: tile cannot extend outside image

Do you know whats possibly going on? For some other files, it works.
