v0.4.18

ruviz v0.4.18

Released: 2026-05-24

Highlights

• Heatmap and contour colorbars now scale consistently when rendering at higher DPI or through max_resolution.
• Colorbar tick labels, rotated labels, width, margin, and border stroke now use the same logical sizing model as the rest of the plot.
• Existing plots keep their data rendering unchanged; this release focuses on colorbar layout and stroke fidelity.

Version Alignment

This release keeps the published workspace packages aligned on one version:

• ruviz 0.4.18
• ruviz-web 0.4.18
• ruviz-gpui 0.4.18
• npm ruviz 0.4.18
• PyPI ruviz 0.4.18

Fixes And Maintenance

• Fixed colorbar label and tick-label sizing so typography is converted from points to render pixels before measurement and drawing.
• Fixed colorbar width and margin scaling so the colorbar does not look undersized beside high-DPI heatmaps.
• Fixed colorbar border stroke scaling so the outline remains visually consistent with other plot strokes.
• Added focused regression coverage for colorbar layout scaling, text extent scaling, and border stroke scaling.

Quality And Validation

This release builds on green CI for PR #74 plus targeted local checks during release prep:

• cargo check --all-targets
• cargo test -p ruviz colorbar -- --test-threads=1
• cargo fmt --all -- --check
• git diff --check
