DiagramConverter Metered Licensing Guide

This guide explains how to use metered (pay-per-use) licensing with DiagramConverter in Aspose.Diagram for .NET. Metered licensing uses a public/private key pair instead of a license file.

Prerequisites

• Aspose.Diagram for .NET (version 26.4.0 or later)
• A metered public key and private key from your Aspose account

Step 1: Apply Metered Keys

Use the Metered class from the Aspose.Diagram namespace to set your keys before calling Process():

using Aspose.Diagram;
using Aspose.Diagram.LowCode;

var metered = new Metered();
metered.SetMeteredKey("your-public-key", "your-private-key");

// Now convert — metered usage is tracked automatically
DiagramConverter.Process("source.vsdx", "output.vdx");

Step 2: Apply Keys at Application Startup

For server applications, apply metered keys once at startup to avoid repeated initialization:

using Aspose.Diagram;

// In Program.cs or Startup.cs
var metered = new Metered();
metered.SetMeteredKey(
    Environment.GetEnvironmentVariable("ASPOSE_PUBLIC_KEY"),
    Environment.GetEnvironmentVariable("ASPOSE_PRIVATE_KEY")
);

Store keys in environment variables or a secrets manager — never hardcode them in source code.

Step 3: Check Metered Consumption

Retrieve current metered consumption to monitor usage:

using Aspose.Diagram;

decimal consumption = Metered.GetConsumptionQuantity();
Console.WriteLine($"Current consumption: {consumption} credits");

Step 4: Convert with Metered License Active

Once keys are applied, use DiagramConverter normally:

using Aspose.Diagram.LowCode;

// Licensing already applied at startup
DiagramConverter.Process("source.vsdx", "output.vdx");
