应用程序图标生成

从一个单一的1024x1024源图标生成所有所需尺寸。

iOS/macOS图标尺寸

#!/bin/bash
# generate-app-icons.sh <source-1024.png> <output-dir>
SOURCE="$1"
OUTDIR="${2:-.}"
mkdir -p "$OUTDIR"

SIZES=(16 20 29 32 40 48 58 60 64 76 80 87 120 128 152 167 180 256 512 1024)
for SIZE in "${SIZES[@]}"; do
  sips -z $SIZE $SIZE "$SOURCE" --out "$OUTDIR/icon-${SIZE}x${SIZE}.png" 2>/dev/null
done
echo "Generated ${#SIZES[@]} icon sizes in $OUTDIR"

Android图标尺寸

# Android adaptive icon sizes
declare -A ANDROID_SIZES=(
  ["mdpi"]=48 ["hdpi"]=72 ["xhdpi"]=96
  ["xxhdpi"]=144 ["xxxhdpi"]=192
)
for DENSITY in "${!ANDROID_SIZES[@]}"; do
  SIZE=${ANDROID_SIZES[$DENSITY]}
  mkdir -p "res/mipmap-$DENSITY"
  sips -z $SIZE $SIZE "$SOURCE" --out "res/mipmap-$DENSITY/ic_launcher.png"
done

网站图标生成

#!/bin/bash
# generate-favicons.sh <source.png> <output-dir>
SOURCE="$1"
OUTDIR="${2:-.}"
mkdir -p "$OUTDIR"

# Standard web favicons
sips -z 16 16 "$SOURCE" --out "$OUTDIR/favicon-16x16.png"
sips -z 32 32 "$SOURCE" --out "$OUTDIR/favicon-32x32.png"
sips -z 180 180 "$SOURCE" --out "$OUTDIR/apple-touch-icon.png"
sips -z 192 192 "$SOURCE" --out "$OUTDIR/android-chrome-192x192.png"
sips -z 512 512 "$SOURCE" --out "$OUTDIR/android-chrome-512x512.png"

# ICO file (requires ImageMagick)
magick "$OUTDIR/favicon-16x16.png" "$OUTDIR/favicon-32x32.png" "$OUTDIR/favicon.ico"

echo "Favicons generated in $OUTDIR"

调色板生成器

根据主色调生成完整配色方案：

// HSL-based palette generation
function generatePalette(hue, saturation = 70) {
  return {
    50:  `hsl(${hue}, ${saturation}%, 97%)`,
    100: `hsl(${hue}, ${saturation}%, 94%)`,
    200: `hsl(${hue}, ${saturation}%, 86%)`,
    300: `hsl(${hue}, ${saturation}%, 74%)`,
    400: `hsl(${hue}, ${saturation}%, 62%)`,
    500: `hsl(${hue}, ${saturation}%, 50%)`,  // Primary
    600: `hsl(${hue}, ${saturation}%, 42%)`,
    700: `hsl(${hue}, ${saturation}%, 34%)`,
    800: `hsl(${hue}, ${saturation}%, 26%)`,
    900: `hsl(${hue}, ${saturation}%, 18%)`,
    950: `hsl(${hue}, ${saturation}%, 10%)`,
  };
}
