This pattern is useful when a process produces separate PDF artifacts that need to be combined.

It comes from the source example at Example/Example03.Merging/Example03.ps1.

When to use this pattern

• You receive multiple PDFs from upstream steps.
• The output should be one merged document.
• You want the merge step to be scriptable.

Example

Import-Module .\PSWritePDF.psd1 -Force

$inputFiles = @(
    "$PSScriptRoot\Input\OutputDocument0.pdf"
    "$PSScriptRoot\Input\OutputDocument1.pdf"
)
$outputFile = "$PSScriptRoot\Output\OutputDocument.pdf"

Merge-PDF -InputFile $inputFiles -OutputFile $outputFile -Verbose

What this demonstrates

• using an array of input files
• writing a deterministic output path
• adding PDF merge to a larger automation
