Unimplemented feature when converting emojis to image #7854

This sounds like it might be a message from FreeType, the library used by Pillow to render text: Pillow/Tests/test_imagefont.py Lines 983 to 985 in 1b7bcfb How did you install Pillow (on both systems)? What is the output of |

If it's helpful information, I'm on an M1 with macOS 14.3.1, and I don't see the error. Investigating, https://stackoverflow.com/questions/63742055/freetype-colour-rendering-ft-load-glyph-returns-unimplemented-feature suggests that FreeType being built without |

So @garymh is the environment with the error? How did he install Pillow? |

@garymh I'm assuming you also installed Pillow using brew? Could you please provide the output of |
Sure, any relevant parts you're looking for though? I'm a dev so I have quite a few things installed 🙃 Here are python related things: |

Everything related to the font stack. Unless I'm forgetting something, that should be freetype, harfbuzz, fribidi, libraqm, libpng. |

Got it! |

I attempted to replicate in macOS 14 arm64 on GitHub Actions, with but it passed. |
|
If you install Pillow from this PyPI wheel, does the problem still occur? I don't expect it to fix it, but if the error still occurs with this, that means I could potentially put together a wheel with better logging for you to run. If it doesn't, are you open to building Pillow from source? |

Closing this issue as no feedback has been received. |

Could you describe in words what you're expecting? The sequence of unicode characters being requested is - woman, zero width joiner, manual wheelchair, zero width joiner, black rightwards arrow, variation selector-16. If I trim the last two characters from the string, then it renders fine on my machine.
|
|
I was trying to create an image from emoji using the native emoji font on macOS. What character did you trim exactly ? Is my emoji sequence not correct 🤨 ? FYI I am using this list as my emoji source |
It seems you are still using brew to install Pillow. If you are using a wheel from PyPI (e.g. the one linked by @radarhere above), you should see the following: Could you please test with Pillow installed from PyPI? This one should work: https://files.pythonhosted.org/packages/5e/77/4cf407e7b033b4d8e5fcaac295b6e159cf1c70fa105d769f01ea2e1e5eca/pillow-10.3.0-cp312-cp312-macosx_11_0_arm64.whl This would at least let us know if the issue is specific to the brew build of Pillow (or other used libraries). |

I find that running convert_emoji_to_png("👩🦽➡️"[:-2], 'test')works. So from your emoji source, I find that 'woman in manual wheelchair', works, but 'woman in manual wheelchair facing right' doesn't. |
|
@radarhere I think the problem comes from the right arrow modifier then. All the following emojis have this modifier, here is an example here are the emojis causing problems : |
|
I've sent an e-mail to FreeType asking them if they have any thoughts.
Hi,
Over at Python Pillow, a user has tried to render an emoji with macOS’ Apple Color Emoji.ttc - #7854 (comment). The emoji is the combination of ‘woman’ U+1F469, 'zero width joiner’ U+200D, 'manual wheelchair’ U+1F9BD, 'zero width joiner’ U+200D, 'black rightwards arrow’ U+27A1, 'variation selector-16’ U+FE0F, with the intention of being a woman in a manual wheelchair facing right. However, FreeType returns an Unimplemented_Feature error. Interesting, it only doesn’t do this for just a woman in a manual wheelchair. To demonstrate, the following code attempts to use woman in a manual wheelchair, and then woman in a manual wheelchair facing right. The error only occurs in the second instance. FT_Library library;
FT_Init_FreeType(&library);
FT_Face face = NULL;
FT_New_Face(library, "/System/Library/Fonts/Apple Color Emoji.ttc", 0, &face);
FT_Set_Pixel_Sizes(face, 0, 64);
int error = FT_Load_Glyph(face, 1507, FT_LOAD_DEFAULT);
if (error) {
printf("1507: error %d\n", error);
}
error = FT_Load_Glyph(face, 1508, FT_LOAD_DEFAULT);
if (error) {
printf("1508: error %d\n", error);
}I’ve attached images that, as far as I can see, show that both indexes are present in the font. Any thoughts as to why one should fail but not the other would be appreciated. Thanks. |
|
I still need to continue the conversation with FreeType, but here is part of the initial response.
|
|
@radarhere Thanks for the update ! I look forward to get a solution. Please, tell me if you need any other information / tests. |
|
Ok, after some further investigation, I found that the graphic type 'flip' is being used. This is a new feature from Apple (I can't even find documentation about it), and something that FreeType doesn't support yet. In my e-mails with FreeType, they have said that supporting this feature would be nice, and so I've created https://gitlab.freedesktop.org/freetype/freetype/-/issues/1282 |
What did you do?
Converting emoji text using
Apple Color Emoji.ttcfont to png file usingpillow. The behavior is different between two macs. On one configuration (see below) the script is correctly generating images from all emoji and on the other hand, for another configuration, the script is returning an error for some emojis.What did you expect to happen?
What actually happened?
With the second cofiguration, the script returns
Note that it seems to be a problem only for emojis from 15.1 version, see this issue.
What are your OS, Python and Pillow versions?
Configuration where the script is working:
Configuration where the script returns an error:
