Implementation Guide

Loading a VSX File

Overview:

This feature allows you to load your source .vsx file into the conversion engine.

Step-by-Step:

1. Create a Converter Instance Start by creating an instance of the Converter class, passing the path of your VSX file.

string vsxFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.vsx"; // Set path to your source .vsx file

using (Converter converter = new Converter(vsxFilePath))
{
    Console.WriteLine("VSX file loaded successfully.");
}

Setting Conversion Options for JPG Format

Overview:

Configure how the document should be converted, specifying the target format.

1. Configure Image Convert Options Create an instance of ImageConvertOptions and set your desired output format to JPEG.

using GroupDocs.Conversion.Options.Convert;

ImageConvertOptions options = new ImageConvertOptions();
options.Format = GroupDocs.Conversion.FileTypes.ImageFileType.Jpg;
Console.WriteLine("Conversion options for JPG set successfully.");

Defining Output Path and Stream Function

Overview:

Specify where the converted files should be saved and how each page is handled during conversion.

1. Set Output Folder and Template Define an output path and a template for naming your output files.

string outputFolder = "YOUR_OUTPUT_DIRECTORY"; // Set your desired output directory path
string outputFileTemplate = Path.Combine(outputFolder, "converted-page-{0}.jpg");

Func<SavePageContext, Stream> getPageStream = savePageContext => 
    new FileStream(string.Format(outputFileTemplate, savePageContext.Page), FileMode.Create);

Console.WriteLine("Output path and stream function defined successfully.");

Practical Applications

This guide equips you to handle various practical scenarios:

  1. Document Management Systems: Automate the conversion of Visio diagrams for easier access in systems like SharePoint.
