I will try to find a way to attach a font file

from home-assistant-custom-components-xiaomi-cloud-map-extractor.

Using TTF stored in a config is much better, as it doesn't require manual changes after every HA update. I will check if it is possible

from home-assistant-custom-components-xiaomi-cloud-map-extractor.

It's impossible using default font, but when you use a font that supports latin characters everything works:

Thanks, just need to know all of my font available. I am using HA in docker.

from home-assistant-custom-components-xiaomi-cloud-map-extractor.

Here you have a command that should retrieve all available fonts:

On RPi I have another error:

Can you check which version of pillow/PIL you have?

pip3 list

I am trying to figure out how deps are installed for HA in docker... Which python is used and where to run the command.

from home-assistant-custom-components-xiaomi-cloud-map-extractor.

Pillow 7.2.0

from home-assistant-custom-components-xiaomi-cloud-map-extractor.

I am trying to run the next:

apk add --no-cache g++ freetype-dev jpeg-dev
pip uninstall pillow
pip install --no-cache-dir pillow

to make sure pillow will be compiled with libfreetype. I am not sure if this will be a persistent solution for HA in docker.

from home-assistant-custom-components-xiaomi-cloud-map-extractor.

It looks like no fonts preinstalled in homeassistant docker image

from home-assistant-custom-components-xiaomi-cloud-map-extractor.

Solution for me was to jump inside HA container and run the next commands:

apk add --no-cache g++ freetype-dev jpeg-dev
pip uninstall pillow
pip install --no-cache-dir pillow
apk add font-noto

and use NotoSansDisplay-Light.ttf font.

BTW it will be nice to choose TTF file stored somewhere in the config folder.

from home-assistant-custom-components-xiaomi-cloud-map-extractor.

from home-assistant-custom-components-xiaomi-cloud-map-extractor.

But there is still an issue with Pillow installed(compiled during installation) without libfreetype. I don't know if there is any solution for that. That how homeassistant processing requirements, looks like no options to control that. So I still have to run the command after every update of HA.

I've hit the same problem, unfortunately my understanding is too limited to follow the instructions above.

I'm left with "ImportError: The _imagingft C module is not installed"

My home assistant is also installed within docker.

Thanks for the great work, really looking forward to being able to utilise this! :-)

After HA was updated to 0.116.2 I cannot fix the issue with the above commands. Every time I see The _imagingft C module is not installed error.

I have the same error. So there is currently no solution to fix the Problem?

Unfortunately I haven't found a solution yet

from home-assistant-custom-components-xiaomi-cloud-map-extractor.

I have added handling to errors thrown during fonts loading.

from home-assistant-custom-components-xiaomi-cloud-map-extractor.

I use HA on Docker with my NAS Synology. No fonts TTF on Synology...

it's Ok wihout font: "FreeSans.ttf" but i can't change the font_size...

texts:
      - text: "Room 1"
        x: 25
        y: 25
        color: [125, 20, 213]
        font_size: 100

@Nicols07 unfortunately it's not possible to change size for a default font

Hi! I came over this issue when troubleshooting a similar issue with one of my own integrations. Not sure if it helps for this case, but I found a workaround by using bitmap fonts and then converting to PIL-fonts. Quite cumbersome solution, but it works better in my case. More info here if you're interested.
