Hi. Thank you for your all works with genpdf. It looks great.

My problem is, i am using creating pdf for my wasm project. So, there is no filesystem. I can download the ttf's files from my server but i don't know how to use it with from_files() method. Is there any way to use fonts without filesystem?

Thank you.

Yes.  The fonts::from_files function is just a shorthand for calling
FontData::load for all four font styles.  Instead of FontData::load
(which takes a path), you can use FontData::new (which takes the raw
font data).  So this gives you two options:  Either you include the font
data in your binary using include_bytes!, or you download the font from
the network.  You can then manually construct a FontFamily instance
using FontData::new.

wasm-card [0] is a project that already uses genpdf from WASM.  It uses
the include_bytes! approach [1].

Please let me know if anything is unclear or does not work properly.

Best,
Robin
