# 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
|
||

|
||
- `src-tauri/icons/icon.ico` — Windows app icon
|
||
- `src-tauri/icons/` — Additional iOS/Android/Appx icons (generated by `tauri icon`)
|
||
- `static/favicon.svg` — Web favicon (SVG)
|
||
- `static/favicon-32.png` — Web favicon fallback (PNG)
|
||
- `scripts/generate-icon-variants.sh` — Color variant generation script

|
||
|
||
### Files Modified
|
||
- `index.html` — Added favicon `<link>` elements
|
||
|
||
### Files Deleted
|
||
- `static/tauri.svg` — Default Tauri branding removed
|
||
|
||
## 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
