Apply Metered License with Aspose.Page for .NET

Introduction

Unlock the full potential of Aspose.Page for .NET by applying a metered license. This tutorial will guide you through the process of setting up and applying the metered license, ensuring smooth and optimized usage of this powerful .NET library.

Prerequisites

Before diving into the steps, make sure you have the following prerequisites in place:

• A valid Aspose.Page for .NET license: You can obtain it from purchase.aspose.com.
• Aspose.Page library installed: Refer to the documentation for installation instructions.
• .NET development environment: Ensure that you have a working .NET environment set up on your machine.

Import Namespaces

In your .NET project, import the necessary namespaces to access Aspose.Page functionalities:

using Aspose.Page;
using Aspose.Page.EPS;
using Aspose.Page.EPS.Device;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;

Step 1: Set Metered Public and Private Keys

Initialize the Aspose.Page.Metered class and set the metered public and private keys. Replace <type public key here> and <type private key here> with your actual keys.

Aspose.Page.Metered metered = new Aspose.Page.Metered();
metered.SetMeteredKey("<type public key here>", "<type private key here>");

Step 2: Load EPS File and Create Document

Specify the path to your EPS file and create a stream to read its content. Then, create an instance of the PsDocument class from the stream.

string dataDir = "Your Document Directory";
System.IO.Stream psStream = new System.IO.FileStream(dataDir + "input.eps", System.IO.FileMode.Open, System.IO.FileAccess.Read);
PsDocument document = new PsDocument(psStream);

Step 3: Convert EPS to PNG Image

Create an ImageDevice for converting the EPS file to a PNG image. Save the EPS file as an image using the ImageSaveOptions.

ImageDevice device = new ImageDevice();
document.Save(device, new ImageSaveOptions());

Step 4: Retrieve Image Bytes

Get the image bytes, where each byte array represents one page. In this case, we have one page.

byte[][] imagesBytes = device.ImagesBytes;

Step 5: Save Image Bytes to File

Save the image bytes to a file, ensuring successful conversion from EPS to PNG.

using (FileStream fos = File.OpenWrite(dataDir + "eps_out.png"))
{
    fos.Write(imagesBytes[0], 0, imagesBytes[0].Length);
}

Step 6: Verify Metered License

Check visually if the metered license is applied successfully. If the resulting image doesn’t contain the red evaluation message, it indicates that the metered license is applied without any issues.

Now you’re ready to leverage the full capabilities of Aspose.Page for .NET with a metered license!
