WARNING: error loading font file Fonts/FortuneCity.ttf

Feedback and support for the PC version of Osmos

WARNING: error loading font file Fonts/FortuneCity.ttf

Postby gagern » Tue Oct 12, 2010 12:38 am

Osmos 1.6.0 for Linux (both demo and full version) won't load the font with freetype 2.4.3, resulting in an application basically lacking all text. Freetype 2.4.2 used to work for me, which led me to file a bug with my distro. The Gentoo developer Ryan Hill has pointed out, though, that the font itself seems to be broken.

Code: Select all
$ ftlint 10 Fonts/FortuneCity.ttf
Fonts/FortuneCity.ttf: glyph  106: 0x0014
1 fail.


With trace output enabled, I could obtain more detailed error information:

The error code 0x14 stands for "invalid outline" according to freetype/fterrdef.h. The error message cannot be reproduced with freetype 2.4.2 either. After doing a git bisect I isolated one commit as the one causing this error message for FortuneCity.ttf. That commit adds a new check that hasn't been present before. It's exactly the one leading to the trace messages.

I don't know much about the internal format of a TTF file, but I'll assume that the freetype devs knew what they were doing and that the font is indeed broken in this respect. I suggest you try obtain a fixed font somehow, or explaining why the font is correct and the check in freetype is in error.

As using the game menu becomes almost impossible without text, and as novice users in particular might not know of a safe way to exit a full screen app they can't control properly, I would also suggest you abort starting the game if the fonts won't load, instead of just issuing a warning and continuing as if nothing happened.

Wow! Nice bug squashing job mate ;) . Anyway, one dirty hack to fix this issue:
- Go to your /usr/share/fonts/TTF/ directory and choose a font you like (remeber the name)
- In a terminal:
# mv /opt/Osmos/Fonts/FortuneCity.ttf /opt/Osmos/Fonts/FortuneCity.ttf.bakcup
# cp /usr/share/fonts/<fontyoulike.ttf> /opt/Osmos/Fonts/FortuneCity.ttf

Re: WARNING: error loading font file Fonts/FortuneCity.ttf

Postby gagern » Sun Oct 17, 2010 5:48 am

OK, I had a look at a two TTF specs (one from Apple, the other from Microsoft) and compated that with FortuneCity.ttf in a hex editor. I have to agree that the font is in fact in violation to the specification:

  • The glyf table starts at 0x7f8 and has length 0x5394 according to the table directory.
  • The glyf table cannot reasonably be any longer, because it's immediately followed by the OS/2 table at 0x5b8c.
  • According to the maxp table, the font has 244=0xf4 glyphs.
  • That matches the 4*(244+1)=0x3d4 bytes length of the loca table.
  • The loca table is located from 0x886f to 0x8c43.
  • The loca table seems to contain an increasing sequence of 32bit integers as required.
  • Many of these integers are larger than 0x5394, the last one is 0x8077.
  • No entry in the loca table seems to actually match the length of the glyf table.

So the font does indeed give locations for glyph specifications that lie outside the corresponding table. How that happened I cannot guess. Adjusting the font to only contain the correct glyphs would require recalculation of checksums, so that would be a bit more work.

I got that wrong, dont't know how. The table length of the glyf table in the header seems to be incorrect, but there is no overlap. So take a hex editor and change these bytes in order to fix the font:
Code: Select all
Change bytes at address 0x80 through 0x8b
from FD C6 55 01 00 00 07 F8 00 00 53 94
to   5D 19 C3 5C 00 00 07 F8 00 00 80 77


That adjusts the length of the glyf table to match the size implied by the last entry of the loca table, which is 0x8077. That makes 0x886e the last byte of the table, which is the last byte preceding the following table (the loca table at 0x886f). So there are two indications that this should be the correct table length. Current freetype libraries accept the modified font all right.

The change adjusts the checksum for the glyf table to match the new range. It doesn't adjust the overall file checksum, as stored in the checkSumAdjustment field of the head table. Calculating that value for a file whose size isn't a multiple of 4 isn't properly defined, and for the most likely definition, a padding with zeroes, the value doesn't verify for the font before the change. freetype doesn't seem to care about that value.

On the whole, the file doesn't honour the alignment requirements expressed in the specs, which require tables to start at four byte boundaries, and to be padded with zeroes to a multiple of four bytes, although the length in the header should reflect the unpadded length. The tables in this font immediately follow one another, with no padding, and as a result of this, the checksum for one table might take the first few bytes of the following table into account as well. At the end of the file, the checksum for the complete file might take arbitrary bytes into account if the corresponding buffer wasn't zeroed prior to calculation. This might result to arbitrary checksums for the whole file.

Perhaps you want to be even more compliant with the TTF spec, and therefore want to fix those alignment problems and the overall file checksum as well. To do so, you can pas the font through the following Python script after making the adjustment outlined above. This will increase the font size by one byte, but might improve portability. Don't know of any font system that actually requires this, though.

Code: Select all
#!/usr/bin/python

import struct
import sys

if len(sys.argv) == 2:
    inFile = sys.argv[1]
    outFile = sys.argv[1]
elif len(sys.argv) == 3:
    inFile = sys.argv[1]
    outFile = sys.argv[2]
else:
    print "Usage: %s input.ttf [output.ttf]" % sys.argv[0]
    exit

with open(inFile, 'rb') as f:
    data = f.read()

(sfntVersion, numTables, searchRange, entrySelector, rangeShift) = \
    struct.unpack('>I4H', data[:12])
if sfntVersion != 0x10000:
    print "Unknown sfnt version"
    exit

checkSumAdjustIndex = -1
result = list(struct.unpack('>%dI' % (3 + numTables*4),
                            data[:12 + numTables*16]))
tables = []
for i in range(numTables):
    (tag, checkSum, offset, length) = result[3 + i*4 : 7 + i*4]
    dwords = (length + 3)/4
    tableData = data[offset : offset + length]
    tableData += '\0'*(4*dwords - length)
    tableData = list(struct.unpack('>%dI' % dwords, tableData))
    tables.append((offset, length, i, tableData))
for offset, length, i, tableData in sorted(tables):
    if data[12 + i*16 : 16 + i*16] == 'head':
        tableData[2] = 0
        checkSumAdjustIndex = len(result) + 2
    result[4 + i*4] = sum(tableData) & 0xffffffff
    result[5 + i*4] = 4*len(result)
    result.extend(tableData)
if checkSumAdjustIndex != -1:
    result[checkSumAdjustIndex] = (0xb1b0afba - sum(result)) & 0xffffffff
result = struct.pack('>%dI' % len(result), *result)

with open(outFile, 'wb') as f:
    f.write(result)

Or if you prefer a hex editor over a python interpreter, and your hex editor can insert bytes (at 0x886f):

Thanks for the great detective work on this gagern, fab stuff! We've got someone on it, hoping to have a nice cleanup to that font soon.

Cheers mate!

Please bundle an uncorrupted font with the Humble Indie Bundle. I just bought it and the game is unplayable (for me and for all with a newer FreeType version) because of this bug. The above Hex-Hack works wonderfully.

Dowloading this (http://www.searchfreefonts.com/free/fortunecity.htm) font fixed it for me.

Is this the same font (although a different version)?

Visually it looks the same. File size is much smaller, though, so I assume it might contain fewer glyphs.

For those unwilling to (install and) use a hex editor, I can suggest the following bash snippet:
Code: Select all
echo -n $'\x5d\x19\xc3\x5c' | dd of=FortuneCity.ttf bs=1 conv=notrunc seek=128
echo -n $'\x80\x77' | dd of=FortuneCity.ttf bs=1 conv=notrunc seek=138

This adjusts the size, but not the alignment. It should be enough to make freetype happy.
