ImageMagick Moltbot Skill

Comprehensive ImageMagick operations for image manipulation in Moltbot.

Installation

macOS: brew install imagemagick Linux: sudo apt install imagemagick # Debian/Ubuntu sudo dnf install ImageMagick # Fedora Verify: convert --version

1. Remove Background (white/solid color → transparent)

./scripts/remove-bg.sh input.png output.png [tolerance] [color] ParameterDefaultRangeDescriptioninput.png——Source imageoutput.png——Output transparent PNGtolerance200-255Color matching fuzz factorcolor#FFFFFFhexColor to remove Examples: ./scripts/remove-bg.sh icon.png icon-clean.png # default white ./scripts/remove-bg.sh icon.png icon-clean.png 30 # loose tolerance ./scripts/remove-bg.sh icon.png icon-clean.png 10 "#000000" # remove black

2. Resize Image

convert input.png -resize 256x256 output.png

3. Convert Format

convert input.png output.webp # PNG → WebP convert input.jpg output.png # JPG → PNG convert input.png -quality 80 output.jpg # Compress

4. Rounded Corners (iOS style)

convert input.png -alpha set -virtual pixel transparent \ -distort viewport 512x512+0+0 \ -channel A -blur 0x10 -threshold 50% \ output-rounded.png

5. Add Watermark

convert base.png watermark.png -gravity southeast -composite output.png

6. Batch Thumbnail Generation

for f in *.png; do convert "$f" -resize 128x128 "thumbs/$f"; done

7. Color Adjustments

convert input.png -brightness-contrast 10x0 output.png # brighter convert input.png -grayscale output.png # grayscale convert input.png -modulate 100,150,100 output.png # more saturation

Flat Icon → Transparent Background

./scripts/remove-bg.sh icon.png icon-clean.png 15

Generate App Icon Set (iOS)

for size in 1024 512 256 128 64 32 16; do convert icon.png -resize ${size}x${size} icon-${size}.png done

Optimize for Web

convert large.png -quality 85 -resize 2000x2000\> optimized.webp

Tips

Higher tolerance (20-50): Better for anti-aliased edges, may remove some foreground Lower tolerance (5-15): Preserves detail, may leave color fringes For flat icons: 10-20 usually works best Use -quality for JPEG/WebP compression (0-100) Use -strip to remove metadata for smaller files
