Hi, my laptop is small, the default option of wechat makes everything too big, and could you please make it as an option that user can set manually? thank you very much!

We have a new feature to set DPI before you start.

You can try to set DOCHAT_DPI=96 to see if it helps?

DOCHAT_DPI=96 dochat.sh

See: https://github.com/huan/docker-wechat#dochat_dpi

my screen is small, and this is the default dpi, with -e DOCHAT_DPI=96, chatting dialog size seems to be ok, but the fonts will be bad.

most fonts seems to be ok, some fonts seems to be not good.

after i uncheck the auto screen size setting from setting page

the screen seems to be like this

when i run docker with dpi

i think maybe this problem also affect the fonts display.

Understood.

If we can get to know the registry key and value of that option, then we can be very easy to disable it by config an environment variable.

this one, with the default command, the fonts seems to be fine on my laptop.
here is the screenshot for the fonts

the option "auto screen size" is also checked by default, but screensize is not so big as your docker, it seems as big as your docker command with dpi=96.

That's by design: DoChat v0.5 are using a default DPI=120, which is 125% larger than the default setting 96 DPI.

And I found that in Ubuntu, it seems that the font size can follow the DPI setting and will be resized as expected.

I believe there are other settings that need to be set under the Debian distribution.

ok, i see, thank you very much!

Is there anyone known the following DPI environment variables?

1. GDK_SCALE
2. GDK_DPI_SCALE

Will they be helpful for our DoChat? If so, how to use them?
