|
||||
|
||||
### Required: Generate PNG Icons
|
||||
iOS Safari requires PNG format for apple-touch-icon. Choose one method:
|
||||
|
||||
**Method 1: Browser-based (Easiest)**
|
||||
```bash
|
||||
# Open in browser
|
||||
open scripts/generate-png-icons.html
|
||||
# Download all PNGs and save to public/ directory
|
||||
```
|
||||
|
||||
**Method 2: Using Sharp**
|
||||
```bash
|
||||
npm install --save-dev sharp
|
||||
node scripts/convert-with-sharp.js
|
||||
```
|
||||
|
||||
**Method 3: Using ImageMagick**
|
||||
```bash
|
||||
brew install imagemagick
|
||||
convert public/icon-192.svg -resize 192x192 public/icon-192.png
|
||||
convert public/icon-512.svg -resize 512x512 public/icon-512.png
|
||||
convert public/apple-touch-icon.svg -resize 180x180 public/apple-touch-icon.png
|
||||
convert public/favicon.svg -resize 32x32 public/favicon-32.png
|
||||
```
|
||||
