How do PNG fonts work?

[alexgleason]

I noticed the docs say that .png fonts are supported. I'm hoping I can get clarity on what this means exactly.

• Is the PNG font a recognized standard? Eg do multiple programs use the same format
• Is it just a row of characters in a specific order?
• Are only monospace fonts supported?
• Does it have to be 8px?
• Are there any examples?

Thanks!

In older versions, there was a fonts.dat

In the latest version, I don't know. Here you will find some explanations

Is the PNG font a recognized standard?

I don't believe so

Is it just a row of characters in a specific order?

Yes, 16 rows by 128 columns, supporting the first 2048 unicode characters.

Are only monospace fonts supported?

yes, all characters must have the same width and height.

Does it have to be 8px?

no, the total image width is a multiple of 128 and total image height is a multiple of 16. The size of each character is thus fixed based on the size of the overall png.

Are there any examples?

yes, from the alttp resource pack: https://gitlab.com/solarus-games/solarus-alttp-pack/blob/master/data/fonts/alttp.png
