Crate noto_sans_mono_bitmap

Provides pre-rasterized characters from the “Noto Sans Mono” font in different sizes and font weights for multiple unicode ranges. This crate is no_std and needs no allocations or floating point operations. Useful in kernels and bootloaders when only “soft-float” is available. Strictly speaking, this crate is more than a basic bitmap font, because it encodes each pixel as a byte and not as a bit, which results in a much nicer result on the screen.

• Original font files taken from: https://fonts.google.com/noto/specimen/Noto+Sans+Mono
• License: SIL Open Font License (OFL) https://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&id=OFL

TL;DR

• ✅ no_std, zero allocations, no floating point operations
• ✅ most important symbols, numbers, and letters as pre-rasterized constant. Unicode-ranges are selectable.
• ✅ Noto Sans Mono font as base
• ✅ different sizes and font weights (light, normal, bold)
• ✅ nice anti-aliasing/smoothing and better looking than legacy bitmap fonts
• ✅ every pixel is encoded in a byte (0-255) and not a bit, which results in a much nicer result on the screen.
• ✅ relevant font sizes, such as 14, 18, 22, and 32px (as optional build time features)
• ✅ zero dependencies
• ✅ All characters are aligned in their box/raster. If they are printed next to each other, the result looks nice.
