Numbering and font on linux

[dogarrowtype]

Hi, awesome fork.
On linux at least, when saving individual images, webui.py starts at a negative number. (-0001, 00000, 00001, 00002, etc). Saving a grid is fine.
And, when the font "arial.ttf" is not present on the system (most linux distros don't package arial), the script throws an error (doesn't crash though) and refuses to show any images on the gradio ui. It's throwing an error in image_grid() that is easily fixed by replacing with "data/DejaVuSans.ttf".

I'm happy to provide more debugging info if you need it, or test on linux.

I think this might have been fixed, there is get_font(fontsize): now which tries to load fonts = ["arial.ttf", "DejaVuSans.ttf"]

The number should have been fixed too

leaving open for now and moving to dev repo

Both of these issues have been fixed, thanks!

Out of curiosity, instead of calling a specific font, is it possible to just call a general font-family, like sans-serif, instead? That way there should be no issues with whatever fonts users have installed?

Unfortunately I don't think it works like that, the font is used to put the text on the prompt matrix images so needs the font file.

Please see here where I implemented a fix in a docker image Sygil-Dev/stable-diffusion@9bebf68 You should be able to do the same thing on your actual system.

This basically "installs" the font and I believe should be where PIL will search for the ttf file on a linux system.

The alternative would be to extend the list to include the path fonts = ["data/DejaVuSans.ttf", "arial.ttf", "DejaVuSans.ttf"]
