OSError: invalid face handle

[eroux]

What did you do?

I ran the following code:

from PIL import Image, ImageDraw, ImageFont, features

print(features.check('raqm'))
print(Image.PILLOW_VERSION)

img = Image.new('RGB', (800, 300), color = (73, 109, 137))
d = ImageDraw.Draw(img)
fnt = ImageFont.truetype('NotoSansTibetan-Regular.ttf', 24, layout_engine=ImageFont.LAYOUT_BASIC)
d.text((10, 10), "༄༅། །སྒྲུབ།", font=fnt, fill=(255, 255, 0))
img.save('result.png')
fnt = ImageFont.truetype('NotoSansTibetan-Regular.ttf', 24, layout_engine=ImageFont.LAYOUT_RAQM)
print("things work until...")
res = fnt.getmask("༄༅། །སྒྲུབ།", features=['ccmp', 'abvs', 'blws', 'calt', 'liga', 'kern', 'abvm', 'blwm', 'mkmk'])

What did you expect to happen?

No segfault

What actually happened?

Here's the console output:

What versions of Pillow and Python are you using?

• Pillow 5.0.0
• Python 3.5.3
• libraqm is manually installed, branch master, commit cf6ec2c4a31785c1092e38569225d1d6a294111b

What platform are you on?

[eroux]

Linux, up-to-date Debian stable

[wiredfool]

It's happening OMM, OSX 10.12.6, from binary osx wheels of 5.1.0

[eroux]

@khaledhosny any hint on where it could come from? Is there a "safer" commit/release of raqm that should be used?

[khaledhosny]

I don’t see where Raqm is involved here, invalid face handle is an error from FreeType, probably somewhere is passing an invalid FT_Face to Raqm.

[eroux]

I see... thanks for taking a look!

[navenduagarwal]

did anyone find a solution, for me this error started happening as soon in installed depends/install_raqm.sh

[johngsk]

Also having this issue. It's also inconsistent. Sometimes my script completes with no error and sometimes throws this OSError (seemingly a random string in the array of strings I am drawing each time) then crashes.

[ghost]

Just started having this issue

Minimal code to reproduce:

from PIL import ImageFont

font = ImageFont.truetype("arial.ttf") # using arial as example, use any font you'd like
print(font.getsize("Hello World"))

getting error running with raqm how to resolve

code:

from PIL import Image, ImageDraw, ImageFont

img = Image.new('RGB', (800, 300), color = (73, 109, 137))
d = ImageDraw.Draw(img)
fnt = ImageFont.truetype('NotoSansTibetan-Regular.ttf', 24, layout_engine=ImageFont.LAYOUT_RAQM)
d.text((10, 10), "༄༅། །སྒྲུབ།", font=fnt, fill=(255, 255, 0))

OSError: invalid face handle

[Belval]

Hi, I have the same issue, it seems that downloading libraqm on Ubuntu 18.04 changes the Pillow installation, and cause this issue with non latin fonts. Even when removing it, the issue persists, and I have not been able to generate text without having it raise the exception.

When doing the same thing with a clean OS install, the error does not happen until I reinstall libraqm at which point I am back in a broken state.

Is there a known fix for this?

[radarhere]

@Belval since you've been dedicated enough to try this on a clean OS, could you provide step-by-step instructions on how to replicate?

[eroux]

are there people around who can't reproduce the issue?

[radarhere]

I can't replicate on my macOS Mojave, or on Ubuntu 18.04 on Travis CI.

[Belval]

@radarhere would a Dockerfile work? I can put one together today if that helps.

[radarhere]

That would be great, thanks.

[zhenglilei]

Another thing is to check if the error is due to the environment language setting

apt-get install -y locales
locale-gen en_US.UTF-8
export LC_ALL=en_US.UTF-8 

My error goes away after I set up en_US.UTF-8.

[nulano]

Reproduced on GHA: https://github.com/nulano/Pillow/actions/runs/234697378
I suspect this issue is caused by a mismatch in system FreeType and wheel FreeType ABI on the following lines:

Pillow/src/_imagingft.c

Lines 472 to 475 in 4174d42

	if (!(*p_raqm.set_freetype_face)(rq, self->face)) {
	PyErr_SetString(PyExc_RuntimeError, "raqm_set_freetype_face() failed.");
	goto failed;
	}

Edit: The logs expired, re-run with 8.0.1 added: https://github.com/nulano/Pillow/actions/runs/419599965
I also ran the function in a loop to reproduce #4225 as well (click through to individual jobs to see if they fail immediately or after a few iterations).

[bsde1234]

I also had this issue. Fixed by

pip uninstall pillow
python3 -m pip install -U https://github.com/python-pillow/Pillow/archive/master.zip

[Zverik]

Could we please have a fix for this in Pillow? As I see it, there are reported and verifiable segfaults in Pillow on a basic operation for three years, and a working fix has been suggested half a year ago. Still this has been neither fixed nor documented, and people from dozens of projects have to spend time googling the issue (see the stream of mentions above)? As I see it, simply changing the default value would work.

[wiredfool]

@Zverik It's not a default value issue. The potential core underlying issue was identified in late November, and is a packaging/licensing issue where portions of the code will use the system Freetype library and portions using the packaged library.

[Zverik]

Oh, right, I see this error is also discussed in #4225 and the fix is drafted in #5062. Thanks for the tip @wiredfool, let's hope the fix works :)

[radarhere]

The proposed fix has been merged, so this should be retested when Pillow 8.2.0 is released.

[radarhere]

Pillow 8.2.0 has now been released.

[Codeize]

@radarhere Fixed the issue it seems, thanks!

[khaledmsm]

i have a problem with pillow, when i'm trying to paste image it doesn't showing in images

[radarhere]

Your problem doesn't seem related to this issue. If you could open a new issue with a self-contained example, so that we can run the same code that you are running, that would be helpful.
