TechSmith Sdk Patterns
Overview
Production patterns for TechSmith COM API: capture factories, output configuration, and batch processing.
Instructions
Step 1: Capture Factory Pattern
function New-SnagitCapture {
param(
[ValidateSet('Desktop', 'Window', 'Region')]
[string]$InputType = 'Window',
[ValidateSet('PNG', 'JPEG', 'BMP', 'GIF')]
[string]$Format = 'PNG',
[string]$OutputDir = "C:\Screenshots",
[bool]$Preview = $false
)
$inputMap = @{ Desktop = 0; Window = 4; Region = 2 }
$formatMap = @{ PNG = 3; JPEG = 4; BMP = 0; GIF = 2 }
$capture = New-Object -ComObject Snagit.ImageCapture
$capture.Input = $inputMap[$InputType]
$capture.Output = 2 # File
$capture.OutputImageFile.FileType = $formatMap[$Format]
$capture.OutputImageFile.Directory = $OutputDir
$capture.OutputImageFile.Filename = "capture_$(Get-Date -Format 'yyyyMMdd_HHmmss')"
$capture.EnablePreview = $Preview
return $capture
}
# Usage
$cap = New-SnagitCapture -InputType Window -Format PNG
$cap.Capture()Step 2: Batch Camtasia Rendering
function Invoke-CamtasiaBatchRender {
param(
[string[]]$ProjectFiles,
[string]$OutputDir,
[string]$Preset = "MP4 - Smart Player (up to 1080p)"
)
$producer = "C:\Program Files\TechSmith\Camtasia 2025\CamtasiaProducer.exe"
$results = @()
foreach ($project in $ProjectFiles) {
$name = [System.IO.Path]::GetFileNameWithoutExtension($project)
$output = Join-Path $OutputDir "$name.mp4"
$proc = Start-Process -FilePath $producer -ArgumentList @(
"/i", "`"$project`"",
"/o", "`"$output`"",
"/preset", "`"$Preset`""
) -Wait -PassThru
$results += @{ File = $name; ExitCode = $proc.ExitCode }
}
return $results
}Error Handling
| Pattern | Use Case | Benefit |
|---|---|---|
| Factory function | Different capture types | Consistent configuration |
| Batch rendering | Multiple projects | Automated pipeline |
| Timestamped names | Avoid overwrites | Unique filenames |
