# Image Manipulation with ImageMagick


This skill enables image processing and manipulation tasks using ImageMagick

across Windows, Linux, and macOS systems.


When to Use This Skill


Use this skill when you need to:


- Resize images (single or batch)

- Get image dimensions and metadata

- Convert between image formats

- Create thumbnails

- Process wallpapers for different screen sizes

- Batch process multiple images with specific criteria


Prerequisites


- ImageMagick installed on the system

- **Windows**: PowerShell with ImageMagick available as `magick` (or at `C:\Program Files\ImageMagick-*\magick.exe`)

- **Linux/macOS**: Bash with ImageMagick installed via package manager (`apt`, `brew`, etc.)


Core Capabilities


1. Image Information


- Get image dimensions (width x height)

- Retrieve detailed metadata (format, color space, etc.)

- Identify image format


2. Image Resizing


- Resize single images

- Batch resize multiple images

- Create thumbnails with specific dimensions

- Maintain aspect ratios


3. Batch Processing


- Process images based on dimensions

- Filter and process specific file types

- Apply transformations to multiple files


Usage Examples


Example 0: Resolve `magick` executable


**PowerShell (Windows):**

powershell 
# Prefer ImageMagick on PATH
$magick = (Get-Command magick -ErrorAction SilentlyContinue)?.Source

# Fallback: common install pattern under Program Files
if (-not $magick) {
    $magick = Get-ChildItem "C:\\Program Files\\ImageMagick-*\\magick.exe" -ErrorAction SilentlyContinue |
        Select-Object -First 1 -ExpandProperty FullName
}

if (-not $magick) {
    throw "ImageMagick not found. Install it and/or add 'magick' to PATH."
}

**Bash (Linux/macOS):**

bash 
# Check if magick is available on PATH
if ! command -v magick &> /dev/null; then
    echo "ImageMagick not found. Install it using your package manager:"
    echo "  Ubuntu/Debian: sudo apt install imagemagick"
    echo "  macOS: brew install imagemagick"
    exit 1
fi

Example 1: Get Image Dimensions


**PowerShell (Windows):**

powershell 
# For a single image
& $magick identify -format "%wx%h" path/to/image.jpg

# For multiple images
Get-ChildItem "path/to/images/*" | ForEach-Object { 
    $dimensions = & $magick identify -format "%f: %wx%h`n" $_.FullName
    Write-Host $dimensions 
}

**Bash (Linux/macOS):**

bash 
# For a single image
magick identify -format "%wx%h" path/to/image.jpg

# For multiple images
for img in path/to/images/*; do
    magick identify -format "%f: %wx%h\n" "$img"
done

Example 2: Resize Images


**PowerShell (Windows):**

powershell 
# Resize a single image
& $magick input.jpg -resize 427x240 output.jpg

# Batch resize images
Get-ChildItem "path/to/images/*" | ForEach-Object { 
    & $magick $_.FullName -resize 427x240 "path/to/output/thumb_$($_.Name)"
}

**Bash (Linux/macOS):**

bash 
# Resize a single image
magick input.jpg -resize 427x240 output.jpg

# Batch resize images
for img in path/to/images/*; do
    filename=$(basename "$img")
    magick "$img" -resize 427x240 "path/to/output/thumb_$filename"
done

Example 3: Get Detailed Image Information


**PowerShell (Windows):**

powershell 
# Get verbose information about an image
& $magick identify -verbose path/to/image.jpg

**Bash (Linux/macOS):**

bash 
# Get verbose information about an image
magick identify -verbose path/to/image.jpg

Example 4: Process Images Based on Dimensions


**PowerShell (Windows):**

powershell 
Get-ChildItem "path/to/images/*" | ForEach-Object { 
    $dimensions = & $magick identify -format "%w,%h" $_.FullName
    if ($dimensions) {
        $width,$height = $dimensions -split ','
        if ([int]$width -eq 2560 -or [int]$height -eq 1440) {
            Write-Host "Processing $($_.Name)"
            & $magick $_.FullName -resize 427x240 "path/to/output/thumb_$($_.Name)"
        }
    }
}

**Bash (Linux/macOS):**

bash 
for img in path/to/images/*;
