unofficial acb file with 3219 colors

Example Pantone Color Processing Workflow

This repository contains the scripts and instructions for processing Pantone color images, extracting color data, and creating an ACB file for Adobe applications.

Files Included

• generate-webplinks-powershell.txt: PowerShell script to generate web links.
• webplinks.txt: A text file containing generated web links.
• Labcolors.jsx: JavaScript file for extracting Lab colors in Photoshop.
• createjsonfromcsv-powershell.txt: PowerShell script to create a JSON file from a CSV.
• encode-acb.js: Node.js script to encode a JSON file into an ACB file, pulled from https://github.com/atesgoral/acb
• Pantone Solid Coated 2024 V5.acb: The final ACB file.

Workflow

Step 1: Generate Web Links

1. Run the generate-webplinks-powershell.txt script in PowerShell to generate web links.
2. The links will be saved in the webplinks.txt file.

Step 2: Download Images

1. Use wget to download the images from the valid links in webplinks.txt.
2. Save the downloaded images in the croppedimages directory.

Step 3: Process Images in Photoshop

1. Use Photoshop to manipulate the images in the croppedimages directory to get normalized pixels.
2. Run the Labcolors.jsx script on the croppedimages folder to extract the colors and save them in colors.csv.

Step 4: Create JSON from CSV

1. Run the createjsonfromcsv-powershell.txt script in PowerShell to convert colors.csv to output.json.

   .\createjsonfromcsv-powershell.txt

Step 5: Validate JSON

1. Validate the output.json file online using JSON Formatter.
2. Download the corrected file and rename it to output.json.
3. Place the output.json file in the same directory as encode-acb.js.

Step 6: Generate ACB File

(Put everything from this repo in same directory https://github.com/atesgoral/acb)

1. Run the encode-acb.js script in PowerShell to generate the ACB file.

   node encode-acb.js

2. The resulting ACB file will be named Pantone Solid Coated 2024 V5.acb.

Notes

• Ensure you have the necessary permissions and software installed to run the scripts (PowerShell, Photoshop, Node.js, wget).
• Follow the steps carefully to ensure proper processing and generation of the ACB file.

Extra

If you want rgb or hex values intead of Lab, use this imagemagick to process a directory of images, sort their histograms by the most occurring color, and save the filename and the most occurring color to a CSV file. Do whatever with the csv after. This can be repurposed for many different things like base64 encoding pms values into a portable html5 file or other things.

Requirements

• ImageMagick installed and the path to magick.exe correctly set.
• PowerShell

Usage

1. Set Paths:

   • Update the $magickPath, $imagesDirectory, and $outputCsv variables in the script to point to your actual directories and files.

2. Run the Script:

   • Save the script to a .ps1 file.
   • Open PowerShell with administrative privileges.
   • Run the script:

     .\path\to\your\script.ps1

3. Script Explanation:

   • Set Paths:
     • $magickPath: Path to ImageMagick executable.
     • $imagesDirectory: Directory containing your images.
     • $outputCsv: Path to the output CSV file.
   • Clear and Initialize CSV File:
     • Clears the content of the CSV file if it exists and adds a header row.
   • Get Image Files:
     • Retrieves all .webp files from the specified directory.
   • Process Each Image:
     • For each image, execute the ImageMagick command to get the color histogram.
     • Sort the histogram by the most occurring color and select the top entry.
     • Extract the hex value of the most occurring color.
   • Write to CSV:
     • Writes the filename and the most occurring color to the CSV file.
   • Completion Message:
     • Prints a message indicating that the process is complete and the results are saved.

PowerShell Script

# Define the path to your ImageMagick executable
$magickPath = "C:\Program Files\ImageMagick-7.1.1-Q16-HDRI\magick.exe"

# Define the path to the directory containing the images
$imagesDirectory = "C:\path\to\your\croppedimages"

# Define the path to the output CSV file
$outputCsv = "C:\path\to\output\histogramsort.csv"

# Ensure the output CSV file is empty
Clear-Content $outputCsv

# Add header to the CSV file
Add-Content -Path $outputCsv -Value "Filename,MostOccurringColor"

# Get all image files in the directory
$imageFiles = Get-ChildItem -Path $imagesDirectory -Filter *.webp

foreach ($imageFile in $imageFiles) {
    # Get the full path to the image file
    $imagePath = $imageFile.FullName

    # Execute ImageMagick command to get color histogram information
    $output = & $magickPath convert $imagePath -colors 5 -depth 8 -format "%c" histogram:info: | Sort-Object -Descending | Select-Object -First 1

    # Extract the most occurring color
    $mostOccurringColor = $output -match "#[0-9A-Fa-f]{6}" | Out-Null; $matches[0]

    # Write the filename and most occurring color to the CSV file
    Add-Content -Path $outputCsv -Value "$($imageFile.Name),$mostOccurringColor"
}

# Output completion message
Write-Output "Histogram sorting completed. Results saved to $outputCsv"
