namespace VSTMtoPPTConverter
{
    class Program
    {
        static void Main(string[] args)
        {
            // Initialize the conversion handler
            using (var converter = new Converter("YOUR_DOCUMENT_DIRECTORY\sample.vstm"))
            {
                // Specify your settings and convert
            }
        }
    }
}

Implementation Guide

Let’s break down the implementation into manageable steps.

Step 1: Define Output Path

Start by setting up the output directory and file path. This ensures you know where the converted files will be saved.

string outputFolder = "YOUR_OUTPUT_DIRECTORY";
string outputFile = System.IO.Path.Combine(outputFolder, "vstm-converted-to.ppt");

Explanation:

This code block creates a string for your output folder and combines it with the desired file name using Path.Combine, ensuring cross-platform compatibility in file paths.

Step 2: Load VSTM File

Load your Visio Macro-Enabled Drawing Template by specifying its path:

using (var converter = new Converter("YOUR_DOCUMENT_DIRECTORY\sample.vstm"))
{
    // Conversion logic will follow here.
}

Explanation:

The Converter class is initialized with the file path of your VSTM file, setting up for conversion.

Step 3: Set Conversion Options

Define the format to which you want to convert using PresentationConvertOptions.

var options = new PresentationConvertOptions { Format = GroupDocs.Conversion.FileTypes.PresentationFileType.Ppt };

Explanation:

This snippet creates a PresentationConvertOptions object specifying PowerPoint as the target format.

Step 4: Perform Conversion

Execute the conversion and save the output file:

code converter.Convert(outputFile, options);

Explanation:

The Convert method takes in the specified output path and conversion options to generate the PPT file from the VSTM source.

Troubleshooting Tips:

  • Ensure your input VSTM file is accessible at the specified path.
  • Verify that the output directory exists or create it programmatically if necessary.
