Click on Layers and choose "Add a layer", and "Provide a layer version ARN" and enter the following ARN.

arn:aws:lambda:<YOUR REGION>:764866452798:layer:ghostscript:<VERSION>

arn:aws:lambda:<YOUR REGION>:764866452798:layer:ghostscript-arm64:<VERSION>

Note: ARM64 provides better price-performance ratio for Lambda functions. Consider using ARM64 for new projects.

Works with the following AWS Lambda runtimes which run on Amazon Linux 2:

• nodejs20.x, nodejs18.x, nodejs16.x
• python3.12, python3.11, python3.10, python3.9, python3.8
• java21, java17, java11
• provided.al2, provided.al2023

You can find it at /opt/bin/gs (/opt is where Lambda unpacks layers).

You can run /opt/bin/gs --version to make sure Ghostscript is up and running.

• Docker with multi-platform support (Docker Desktop includes buildx by default)
• For ARM64 builds: Docker buildx must be enabled

Run the build script to create both architecture variants:

./build.sh

This will produce:

• ghostscript-x86_64.zip - x86_64 architecture
• ghostscript-arm64.zip - ARM64 architecture

To publish layers manually (requires AWS credentials and proper permissions):

export TARGET_REGION="us-east-1"
export BASE_DIR="$(pwd)"  # Optional: defaults to current directory
./publish.sh

1. Change version numbers in the version.sh file (GHOSTSCRIPT_VERSION and GS_TAG)
2. Test locally by running ./build.sh to produce both zip files
3. Verify the builds: unzip -l ghostscript-x86_64.zip and unzip -l ghostscript-arm64.zip
4. Publish the new layers using ./publish.sh (set TARGET_REGION and BASE_DIR as needed)
5. Update the version table in this README with the new layer version numbers
