App Icon Design & Implementation Summary

Date: 2026-09-22 12:10 Task: Design and implement an SVG app icon following Android adaptive icon guidelines

Task Description

Designed and implemented a custom app icon for Video Clipper, replacing the default Tauri branding. The icon depicts scissors cutting diagonally across a film strip, rendered in a Material Design + gradient hybrid style with a shadcn-inspired dark palette.

Process

1. Brainstorming — Explored project context, asked clarifying questions (style, subject, color palette, background), proposed 3 approaches (diagonal scissors over film strip, scissors silhouette with notch, scissors framing play triangle), user selected Approach A
2. Design spec — Wrote detailed spec covering canvas/adaptive icon structure, foreground artwork composition, five color palette variants, SVG structure, and output files → docs/superpowers/specs/2026-09-22-app-icon-design.md
3. Implementation plan — 4-task plan covering SVG creation, variant generation, rasterization pipeline, and project reference updates → docs/superpowers/plans/2026-09-22-app-icon.md
4. Subagent-driven execution — All 4 tasks implemented and reviewed via subagent-driven development

Design Decisions

• Style: Material Design geometry + modern gradients, shadcn-inspired dark palette
• Subject: Open scissors cutting a film strip diagonally
• Background: Solid zinc-900 (#18181b)
• Chosen variant: Orange (#fb923c → #ea580c blade gradient, #f97316 cut accent)
• Safe zone: Inner 66% (338×338px) for adaptive icon compatibility

Files Deleted

Tools Used

• rsvg-convert — SVG → PNG rasterization
• npx tauri icon — Multi-platform icon generation from source PNG
• xmllint — SVG validation

Follow-up Items

• Visual tuning of SVG coordinates may be needed after seeing the icon at various sizes in production
• The icon geometry is approximate (hand-authored coordinates); if proportions look off at small sizes (16px favicon), a simplified variant could be created
• Android XML files generated by tauri icon have missing trailing newlines (cosmetic)

Lessons Learned

• npx tauri icon accepts a source PNG and generates all platform icon files automatically (PNGs, ICNS, ICO, iOS, Android) — much simpler than manual rasterization
• rsvg-convert (from librsvg, installed via brew) is available on macOS for high-quality SVG → PNG conversion
• Android adaptive icons require a 66% safe zone — critical artwork must fit within the inner 338×338px of a 512×512 canvas
• Hand-authoring SVG path coordinates without visual feedback is inherently approximate; the plan correctly identified visual iteration as an expected part of the process
