bittermelon vs rosm
A side-by-side editorial comparison of bittermelon and rosm — release velocity, themes, recent moves, and the top alternatives to consider.

bittermelon vs rosm: at a glance
What is bittermelon?
bittermelon is growing from binary bitmaps toward greyscale and color glyphs
The package manipulates bitmap fonts and bitmaps in R, and the recent direction is widening what a glyph can be. v2.3.1 adds greyscale font support by reading the experimental yaff levels property into pixmap glyphs with alpha derived from the level fraction, and makes writing a multi-colored glyph an error rather than silently clamping it. Earlier releases built out the same surface: bm_extract(), an interactive pixel picker, data frame coercion, and format support for other packages' bitmap types.
What is rosm?
rosm 0.3.0 silently deprecates its entire API and rebuilds on wk and curl
rosm downloads and stitches raster map tiles from OpenStreetMap and similar sources for use in R. After six years without a release, 0.3.0 deprecated the whole previous API, dropped the rgdal dependency, and introduced a replacement built on wk geometry and curl's multi-download interface. The follow-up 0.3.1 is documentation and CI work, plus test skips for Bing and Stamen URLs that no longer resolve.

bittermelon is growing from binary bitmaps toward greyscale and color glyphs
◆ Current state
The package manipulates bitmap fonts and bitmaps in R, and the recent direction is widening what a glyph can be. v2.3.1 adds greyscale font support by reading the experimental yaff levels property into pixmap glyphs with alpha derived from the level fraction, and makes writing a multi-colored glyph an error rather than silently clamping it. Earlier releases built out the same surface: bm_extract(), an interactive pixel picker, data frame coercion, and format support for other packages' bitmap types.
◆ Where it's heading
Two things are converging. The representation is moving beyond one-bit glyphs — pixmaps, color, and now greyscale levels with transparency — while the API gets stricter about the boundary between them, refusing to quietly downcast a color glyph on write. Separately, the package has been shedding weight: the embedded monobit copy was removed once it outgrew CRAN size limits, pushing format breadth onto a user-installed dependency.
◆ Prediction
Expect further greyscale and color work now that levels parsing exists — most likely writing that format rather than only reading it, since the write path is where the current release chose to draw a hard error instead.

rosm 0.3.0 silently deprecates its entire API and rebuilds on wk and curl
◆ Current state
rosm downloads and stitches raster map tiles from OpenStreetMap and similar sources for use in R. After six years without a release, 0.3.0 deprecated the whole previous API, dropped the rgdal dependency, and introduced a replacement built on wk geometry and curl's multi-download interface. The follow-up 0.3.1 is documentation and CI work, plus test skips for Bing and Stamen URLs that no longer resolve.
◆ Where it's heading
The package is being brought back from dormancy on modern foundations rather than extended. rgdal's retirement forced the issue, and the maintainer used it to replace the download path with concurrent curl requests and to hand geometry handling to wk. What follows is consolidation: dead built-in tile sources are being tested around rather than replaced, which leaves the source registry as the obvious unfinished edge.
◆ Prediction
The dead Bing and Stamen endpoints are currently skipped rather than fixed, so the next release most likely prunes or re-points the built-in tile source list and continues retiring the silently deprecated functions.
