Verifying Installer Integrity (Checksums and Signatures)

Windows Installer Verification

Download the SHA256 checksum file from the official website
- Look for files named gimp-*-setup.exe.sha256
  - Version-specific checksums
  - Architecture-specific files
  - Language-specific packages
- Save both installer and checksum in the same directory
  - Create dedicated folder
  - Maintain file organization
  - Track versions
- Note the expected checksum value
  - Copy to secure location
  - Verify format
  - Compare with download

Use PowerShell to verify:

# Method 1: Using Get-FileHash
Get-FileHash -Algorithm SHA256 gimp-installer.exe | Compare-Object (Get-Content checksum.txt)

# Method 2: Manual verification
$hash = Get-FileHash -Algorithm SHA256 gimp-installer.exe
$expected = Get-Content checksum.txt
if ($hash.Hash -eq $expected) { Write-Host "Verification successful" }

# Method 3: Batch verification
$files = Get-ChildItem -Path ".\" -Filter "*.exe"
foreach ($file in $files) {
    $hash = Get-FileHash -Algorithm SHA256 $file.FullName
    Write-Host "$($file.Name): $($hash.Hash)"
}

# Method 4: Automated verification script
$installer = "gimp-installer.exe"
$checksum = "checksum.txt"
$hash = Get-FileHash -Algorithm SHA256 $installer
$expected = Get-Content $checksum
if ($hash.Hash -eq $expected) {
    Write-Host "Verification successful" -ForegroundColor Green
} else {
    Write-Host "Verification failed" -ForegroundColor Red
    Write-Host "Expected: $expected"
    Write-Host "Actual: $($hash.Hash)"
}

Troubleshooting:
- If checksums don't match, download the file again
  - Clear browser cache
  - Use different download method
  - Try alternative mirror
- Check for download interruptions
  - Verify file size
  - Check download logs
  - Monitor network connection
- Verify you're using the correct checksum file
  - Check file version
  - Verify file format
  - Compare file names
- Ensure file wasn't modified during download
  - Check file permissions
  - Verify file attributes
  - Monitor file changes

Advanced Verification:

Digital signature verification

# Verify digital signature
Get-AuthenticodeSignature gimp-installer.exe

# Check certificate chain
certutil -verify gimp-installer.exe

File integrity monitoring

# Monitor file changes
$watcher = New-Object System.IO.FileSystemWatcher
$watcher.Path = "."
$watcher.Filter = "gimp-installer.exe"
$watcher.EnableRaisingEvents = $true

Automated verification system

# Create verification script
$config = @{
    Installer = "gimp-installer.exe"
    Checksum = "checksum.txt"
    LogFile = "verification.log"
}

macOS Package Verification

Check the package signature:

# Verify the package signature
pkgutil --check-signature GIMP.pkg

# Check the certificate
security find-certificate -a -c "GIMP" -Z

# Verify certificate chain
security verify-cert -c /path/to/certificate

# Check code signing
codesign -vv -d GIMP.pkg

# Verify notarization
xcrun stapler validate GIMP.pkg

Verify SHA256 checksum:

# Calculate checksum
shasum -a 256 GIMP.pkg

# Compare with provided checksum
echo "expected_checksum GIMP.pkg" | shasum -a 256 -c

# Automated verification
#!/bin/bash
EXPECTED=$(cat checksum.txt)
ACTUAL=$(shasum -a 256 GIMP.pkg | cut -d' ' -f1)
if [ "$EXPECTED" = "$ACTUAL" ]; then
    echo "Verification successful"
else
    echo "Verification failed"
fi

# Batch verification
for pkg in *.pkg; do
    shasum -a 256 "$pkg"
done

Additional Security Checks:

Verify the developer certificate

# Check certificate validity
security verify-cert -c /path/to/certificate

# Verify certificate chain
security verify-cert -k /path/to/keychain

Check Gatekeeper settings

# Check Gatekeeper status
spctl --status

# Verify app notarization
xcrun stapler validate GIMP.pkg

Review security permissions

# Check file permissions
ls -l GIMP.pkg

# Verify ACLs
ls -le GIMP.pkg

Scan for malware (optional)

# Use built-in scanner
xattr -l GIMP.pkg

# Check quarantine status
xattr -d com.apple.quarantine GIMP.pkg

Verify GPG signature:

# Import the GIMP public key
gpg --keyserver keys.gnupg.net --recv-keys 0x7B44D54E

# Verify the signature
gpg --verify gimp-*.tar.bz2.sig

# Check the key fingerprint
gpg --fingerprint 0x7B44D54E

# Advanced key management
#!/bin/bash
KEY_ID="0x7B44D54E"
KEYSERVER="keys.gnupg.net"

# Import key
gpg --keyserver $KEYSERVER --recv-keys $KEY_ID

# Verify key
gpg --fingerprint $KEY_ID

# Check key trust
gpg --check-trustdb

# Verify signature
for file in *.tar.bz2; do
    gpg --verify "${file}.sig" "$file"
done

Check SHA256 checksum:

# Verify the checksum
sha256sum -c gimp-*.tar.bz2.sha256

# Manual verification
sha256sum gimp-*.tar.bz2

# Automated verification script
#!/bin/bash
for file in *.tar.bz2; do
    if [ -f "${file}.sha256" ]; then
        sha256sum -c "${file}.sha256"
    else
        echo "No checksum file for $file"
    fi
done

# Batch verification
find . -name "*.tar.bz2" -exec sha256sum {} \; > checksums.txt
diff checksums.txt original_checksums.txt

Single-Window vs Multi-Window Mode

GIMP offers two distinct interface modes, each with specific advantages for different workflows and user preferences.

Single-Window Mode

Single-Window Mode (the default in modern GIMP versions) consolidates all interface elements into one unified window. This mode is ideal for:

Advantages:

Unified Interface: All tools and dialogs are contained within one main window
Taskbar Efficiency: Only one entry appears in your operating system's taskbar
Monitor Optimization: Perfect for single-monitor setups
Reduced Clutter: Cleaner desktop with fewer floating windows
Modern Workflow: Matches the interface style of contemporary applications

Best For:

Users with single monitors
Those who prefer a consolidated workspace
Beginners learning GIMP
Laptop users with limited screen space

Multi-Window Mode

Multi-Window Mode separates GIMP into independent windows, providing maximum flexibility for workspace arrangement.

Advantages:

Multi-Monitor Support: Dialogs can be spread across multiple screens
Flexible Positioning: Each dialog can be positioned independently
Custom Arrangements: Create unique workspace layouts
Legacy Compatibility: Familiar to users of older GIMP versions
Specialized Workflows: Ideal for specific professional workflows

Best For:

Users with multiple monitors
Professional workflows requiring specific dialog arrangements
Users transitioning from older GIMP versions
Workflows that benefit from having tools in specific screen locations

Switching Between Modes

You can switch between modes at any time:

To Single-Window Mode: Go to Windows > Single-Window Mode
To Multi-Window Mode: Go to Windows > Multi-Window Mode

Important Notes:

Your current workspace layout will be preserved when switching modes
Some dialogs may need to be repositioned after switching
Custom workspace layouts are saved separately for each mode
The mode preference is remembered between GIMP sessions

Choosing the Right Mode

Choose Single-Window Mode if:

You have one monitor
You prefer a unified interface
You're new to GIMP
You want a cleaner desktop

Choose Multi-Window Mode if:

You have multiple monitors
You need specific dialog arrangements
You're used to older GIMP versions
Your workflow benefits from independent dialog positioning

Canvas and File Operations

Working with canvas and file operations forms the foundation of every GIMP project. Understanding how to create, open, save, and manage image files efficiently is crucial for productive image editing. This chapter covers everything from creating new images with proper settings to managing file formats, metadata, and recovery options.

Creating a New Image: Dimensions, Resolution, Fill

Creating a new image in GIMP requires careful consideration of dimensions, resolution, and initial fill options. These settings determine the canvas size, print quality, and starting point for your work. The New Image dialog (Ctrl+N) provides comprehensive options for configuring your canvas before you begin editing.

Image Dimensions:

Width and Height: Set canvas size in pixels, inches, centimeters, millimeters, points, picas, or other units
- Pixel Units: Most common for digital work, absolute size regardless of resolution
  - Web Work: Use pixels for web graphics (e.g., 1920×1080 for full HD banner)
  - Screen Display: Match screen resolutions exactly (e.g., 2560×1440 for QHD monitor)
  - Digital Photography: Use pixel dimensions matching camera output (e.g., 6000×4000 for 24MP camera)
  - Absolute Measurement: Pixels are absolute, not dependent on resolution setting
  - Precision: Pixel values are integers, no decimal precision needed
- Physical Units: Inches, centimeters useful for print work with specific dimensions
  - Print Dimensions: Use inches for US print work (e.g., 8.5×11" for Letter size)
  - International Print: Use centimeters for international print (e.g., 21×29.7cm for A4)
  - Precise Sizing: Physical units ensure exact print dimensions
  - Resolution Dependent: Physical size depends on resolution setting
  - Calculation: GIMP calculates pixels from physical size × resolution
- Unit Selection: Choose unit from dropdown menu in New Image dialog
  - Dropdown Menu: Located next to width/height input fields
  - Quick Switch: Easy switching between units
  - Visual Feedback: Values update immediately when unit changes
  - Workflow Matching: Select unit matching your project needs
- Unit Conversion: GIMP automatically converts between units when you switch
  - Automatic Calculation: GIMP calculates equivalent values automatically
  - Resolution Based: Conversion uses current resolution setting
  - Precision Handling: Handles decimal precision appropriately
  - Rounding: May round to nearest pixel for pixel display
  - Accuracy: Maintains accuracy within rounding limits
- Maximum Dimensions: GIMP supports images up to 300,000 pixels in each dimension
  - Theoretical Maximum: 300,000×300,000 pixels maximum
  - Practical Limits: Practical limits depend on available RAM
  - Memory Calculation: Each pixel uses memory based on color mode and precision
  - Example Calculation: 300,000×300,000 RGB 8-bit = ~270GB RAM (theoretical)
  - Realistic Limits: Most systems handle 10,000-50,000 pixels per dimension comfortably
  - Performance Impact: Very large images significantly impact performance
- Memory Considerations: Larger dimensions require more RAM and processing power
  - RAM Requirements: Image size = width × height × channels × bytes per channel
    - Formula Breakdown:
      - Width × Height: Total number of pixels
      - Channels: RGB = 3 channels, Grayscale = 1 channel, RGBA = 4 channels
      - Bytes per Channel: 8-bit = 1 byte, 16-bit = 2 bytes, 32-bit float = 4 bytes
      - Total: Multiply all factors for total memory per layer
    - Calculation Examples:
      - 5000×3000 RGB 8-bit: 5000 × 3000 × 3 × 1 = 45,000,000 bytes = ~45MB
      - 5000×3000 RGB 16-bit: 5000 × 3000 × 3 × 2 = 90,000,000 bytes = ~90MB
      - 5000×3000 RGB 32-bit: 5000 × 3000 × 3 × 4 = 180,000,000 bytes = ~180MB
      - 5000×3000 Grayscale 8-bit: 5000 × 3000 × 1 × 1 = 15,000,000 bytes = ~15MB
      - 5000×3000 RGBA 8-bit: 5000 × 3000 × 4 × 1 = 60,000,000 bytes = ~60MB
  - Example: 5000×3000 RGB 8-bit = 45MB in memory
    - Single Layer: 45MB for one layer
    - 10 Layers: 450MB total memory
    - 50 Layers: 2.25GB total memory
    - Undo History: Additional memory for undo history (configurable)
    - System Overhead: GIMP uses additional memory for interface and operations
  - 16-bit Impact: Same image in 16-bit = 90MB (2x memory)
    - Memory Doubling: Exactly 2x the memory of 8-bit
    - Quality Benefit: Eliminates banding, smoother gradients
    - Performance Impact: 2x slower processing, 2x more memory
    - When Worth It: Professional photography, extensive editing, print work
    - System Requirements: Requires 2x available RAM
  - 32-bit Impact: Same image in 32-bit float = 180MB (4x memory)
    - Memory Quadrupling: Exactly 4x the memory of 8-bit
    - HDR Support: Required for HDR imaging
    - Performance Impact: 4x slower processing, 4x more memory
    - When Worth It: HDR photography, advanced compositing, scientific imaging
    - System Requirements: Requires 4x available RAM and powerful CPU
  - Layer Multiplication: Each layer uses same amount of memory
    - Memory Calculation: Base layer size × number of layers
    - Example: 5000×3000 RGB 8-bit (45MB) × 20 layers = 900MB
    - Layer Groups: Layer groups don't reduce memory (all layers still loaded)
    - Hidden Layers: Hidden layers still use memory
    - Memory Management: Merge or flatten layers to reduce memory usage
  - System Impact: Large images can slow down entire system
    - RAM Usage: High RAM usage can slow down system
    - Swap Usage: System may use disk swap if RAM insufficient
    - CPU Usage: Large images require more CPU processing
    - Disk I/O: Large files increase disk read/write operations
    - System Responsiveness: Can make entire system less responsive
    - Other Applications: May impact performance of other applications
  - Optimization: Consider image size vs. available system resources
    - Available RAM: Check available system RAM before creating large images
    - System Capabilities: Consider CPU and disk speed
    - Workflow Planning: Plan workflow to minimize memory usage
    - Layer Management: Keep layer count reasonable
    - Precision Choice: Use appropriate precision (don't over-specify)
    - Resolution Choice: Use appropriate resolution for final output
    - Memory Monitoring: Monitor memory usage during work
  - Memory Planning Examples:

- Downsampling: Reducing resolution may cause quality loss
  - Definition: Reducing pixel dimensions (making image smaller)
  - Quality Loss: Some detail is permanently lost
  - Interpolation Impact: Better interpolation methods reduce quality loss
  - Best Method: Lanczos or LoHalo for best downsampling quality
  - When Needed: Reducing file size, creating thumbnails, web optimization
  - Irreversible: Cannot recover lost detail after downsampling
  - Best Practice: Keep original high-resolution version
  - Example: 5000×3000 downsampled to 2500×1500 loses detail
- Upsampling: Increasing resolution doesn't add real detail
  - Definition: Increasing pixel dimensions (making image larger)
  - No New Detail: Cannot create detail that doesn't exist
  - Interpolation: Software guesses new pixel values
  - Quality Impact: May appear softer or less sharp
  - Best Method: Lanczos for best upsampling results
  - Limitations: Limited upsampling before quality degrades significantly
  - Rule of Thumb: Up to 200% enlargement usually acceptable
  - Best Practice: Start with highest resolution source possible
  - Example: 1000×1000 upsampled to 2000×2000 won't add real detail

Resolution Calculation Formulas and Examples:

Pixel Dimensions from Physical Size and DPI:
- Formula: Pixels = (Physical Size in Inches) × DPI
- Example 1: 8" × 10" at 300 DPI
  - Width: 8" × 300 = 2400 pixels
  - Height: 10" × 300 = 3000 pixels
  - Result: 2400×3000 pixels
- Example 2: 21cm × 29.7cm (A4) at 300 DPI
  - Convert to inches: 21cm = 8.27", 29.7cm = 11.69"
  - Width: 8.27" × 300 = 2481 pixels (round to 2480)
  - Height: 11.69" × 300 = 3507 pixels (round to 3508)
  - Result: 2480×3508 pixels
- Example 3: 3.5" × 2" (business card) at 300 DPI
  - Width: 3.5" × 300 = 1050 pixels
  - Height: 2" × 300 = 600 pixels
  - Result: 1050×600 pixels
Physical Size from Pixel Dimensions and DPI:
- Formula: Physical Size = Pixels ÷ DPI
- Example 1: 1920×1080 pixels at 72 DPI
  - Width: 1920 ÷ 72 = 26.67 inches
  - Height: 1080 ÷ 72 = 15 inches
  - Result: 26.67" × 15" (if printed)
- Example 2: 2400×3000 pixels at 300 DPI
  - Width: 2400 ÷ 300 = 8 inches
  - Height: 3000 ÷ 300 = 10 inches
  - Result: 8" × 10" (print size)
DPI Calculation from Pixel Dimensions and Physical Size:
- Formula: DPI = Pixels ÷ Physical Size in Inches
- Example 1: 2400×3000 pixels, 8" × 10" print
  - Width DPI: 2400 ÷ 8 = 300 DPI
  - Height DPI: 3000 ÷ 10 = 300 DPI
  - Result: 300 DPI (consistent)
- Example 2: 1920×1080 pixels, 26.67" × 15" display
  - Width DPI: 1920 ÷ 26.67 = 72 DPI
  - Height DPI: 1080 ÷ 15 = 72 DPI
  - Result: 72 DPI (web standard)
File Size Calculation from Resolution:
- Formula: File Size = (Width × Height × Channels × Bytes per Channel) × Compression Ratio
- Example 1: 8" × 10" at 300 DPI, RGB 8-bit, uncompressed
  - Pixels: 2400 × 3000 = 7,200,000 pixels
  - Channels: 3 (RGB)
  - Bytes per channel: 1 (8-bit)
  - Uncompressed: 7,200,000 × 3 × 1 = 21,600,000 bytes = ~21.6MB
- Example 2: Same image, JPEG quality 85
  - Uncompressed: 21.6MB
  - Compression ratio: ~15-25% (JPEG quality 85)
  - Compressed: 21.6MB × 0.20 = ~4.3MB (approximately)
- Example 3: Same image, 16-bit precision
  - Pixels: 7,200,000
  - Channels: 3
  - Bytes per channel: 2 (16-bit)
  - Uncompressed: 7,200,000 × 3 × 2 = 43,200,000 bytes = ~43.2MB
  - 2x larger than 8-bit version

Troubleshooting Common Issues:

Image Too Large for Memory:
- Problem: GIMP runs out of memory or becomes very slow
- Symptoms: Slow performance, crashes, "out of memory" errors
- Solutions:
  - Reduce image dimensions
  - Use 8-bit instead of 16-bit or 32-bit
  - Work with smaller sections of image
  - Close other applications to free memory
  - Increase system RAM if possible
  - Use grayscale instead of RGB if color not needed
- Prevention: Calculate memory requirements before creating large images
  - Formula: width × height × channels × bytes per channel
  - Example: 10000×10000 RGB 8-bit = ~286MB per layer
  - Consider total memory with multiple layers
Wrong Resolution for Print:
- Problem: Image prints at wrong size or poor quality
- Symptoms: Print too small/large, pixelated, blurry
- Solutions:
  - Check resolution setting (should be 300 DPI for quality prints)
  - Verify pixel dimensions match intended print size
  - Use Image > Print Size to check print dimensions
  - Recalculate: Print size × DPI = required pixels
  - Resample image if needed (Image > Scale Image)

  - Layer Masks: Layer masks add to file size
  - Paths: Paths add minimal size
  - Metadata: Metadata adds minimal size
  - Compression: XCF compression reduces size but maintains editability
  - Examples:
    - 1920×1080 RGB 8-bit, 1 layer: ~6-10MB (compressed)
    - 1920×1080 RGB 8-bit, 10 layers: ~60-100MB (compressed)
    - 1920×1080 RGB 16-bit, 10 layers: ~120-200MB (compressed)
    - 1920×1080 RGBA 8-bit, 20 layers: ~160-320MB (compressed)
- Compression: XCF uses compression but still larger than JPEG/PNG

Saving for Compatibility: Flattening and Merging Layers

When sharing images or exporting to formats that don't support layers, you need to flatten or merge layers. Understanding the difference and when to use each approach is important for maintaining workflow flexibility. Both operations combine layers but with different levels of permanence and flexibility.

Flattening Images:

Complete Merge: Merges all visible layers into single background layer
- All Layers: Combines all visible layers into one
- Background Layer: Result is single background layer
- Layer Structure: Complete layer structure is lost
- Visible Only: Only visible layers are included in flattening
- Layer Order: Final result reflects layer stacking order
Layer Loss: Permanently combines all layers, losing layer structure
- Irreversible: Cannot separate layers after flattening
- Structure Lost: All layer organization is lost
- Properties Lost: Layer properties (modes, opacity) are lost
- Masks Lost: Layer masks are applied and lost
- Edit Limitations: Cannot edit individual elements separately
File Size: Significantly reduces file size
- Size Reduction: File size dramatically reduced
- Single Layer: Only one layer instead of many
- Compression: Better compression with single layer
- Storage Savings: Significant storage space savings
- Transfer Speed: Faster file transfer due to smaller size
Compatibility: Required for formats that don't support layers
- JPEG: JPEG doesn't support layers, requires flattening
- PNG: Standard PNG doesn't support layers (GIMP can save PNG with layers but not standard)
- Web Formats: Most web formats don't support layers
- Print Formats: Some print formats don't support layers
- Universal Compatibility: Flattened images work everywhere
Irreversible: Cannot undo flattening after saving
- Save Required: Must save XCF before flattening to preserve layers
- Undo Limitation: Undo only works before saving
- Backup Essential: Always backup XCF before flattening
