Getting Started with Smart PDF Viewer

This section briefly explains how to include Blazor Smart PDF Viewer component in your Blazor Web App using Visual Studio and Visual Studio code.

Install-Package Syncfusion.Blazor.SfSmartPdfViewer -Version 31.1.17
Install-Package Syncfusion.Blazor.Themes -Version 31.1.17

dotnet new blazor -o BlazorWebApp -int Server
cd BlazorWebApp
cd BlazorWebApp.Client

dotnet add package Syncfusion.Blazor.SfSmartPdfViewer -v 31.2.*
dotnet add package Syncfusion.Blazor.Themes -v 31.2.*
dotnet restore

Register Syncfusion^® Blazor Service

Import the Syncfusion.Blazor and Syncfusion.Blazor.SmartPdfViewer namespace.

@using Syncfusion.Blazor
@using Syncfusion.Blazor.SmartPdfViewer

If the Interactive Render Mode is set to Server, your project will contain a single ~/Program.cs file. So, you should register the Syncfusion^® Blazor Service only in that ~/Program.cs file.

using Syncfusion.Blazor;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddSignalR(o => { o.MaximumReceiveMessageSize = 102400000; });

builder.Services.AddMemoryCache();

// Add service to the container.
builder.Services.AddSyncfusionBlazor();

var app = builder.Build();
....

To Configure Azure OpenAI Service

In Visual Studio, Go to Tools → NuGet Package Manager → Package Manager Console. Run these commands one by one:

Install-Package Azure.AI.OpenAI
Install-Package Microsoft.Extensions.AI
Install-Package Microsoft.Extensions.AI.OpenAI -Version 9.8.0-preview.1.25412.6

In Visual Studio Code, Open terminal in VS Code. Run these commands:

dotnet add package Azure.AI.OpenAI
dotnet add package Microsoft.Extensions.AI
dotnet add package Microsoft.Extensions.AI.OpenAI --version 9.8.0-preview.1.25412.6

To configure the AI service, add the following settings to the ~/Program.cs file in your Blazor Server app.

using Azure.AI.OpenAI;
using Microsoft.Extensions.AI;
using Sample.Components;
using Syncfusion.Blazor;
using Syncfusion.Blazor.AI;
using System.ClientModel;

var builder = WebApplication.CreateBuilder(args);

string azureOpenAiKey = "api-key";
string azureOpenAiEndpoint = "endpoint URL";
string azureOpenAiModel = "deployment-name";
AzureOpenAIClient azureOpenAIClient = new AzureOpenAIClient(new Uri(azureOpenAiEndpoint), new ApiKeyCredential(azureOpenAiKey));
IChatClient azureOpenAiChatClient = azureOpenAIClient.GetChatClient(azureOpenAiModel).AsIChatClient();
builder.Services.AddChatClient(azureOpenAiChatClient);

builder.Services.AddSingleton<IChatInferenceService, SyncfusionAIService>();

var app = builder.Build();
....

Here,

• apiKey: “Azure OpenAI API Key”;
• deploymentName: “Azure OpenAI deployment name”;
• endpoint: “Azure OpenAI deployment end point URL”;

For Azure OpenAI, first deploy an Azure OpenAI Service resource and model, then values for apiKey, deploymentName and endpoint will all be provided to you.

To Configure Ollama for Self-Hosted AI Models

To use Ollama for running self-hosted models:

• Download and install Ollama
  Visit Ollama’s official website and install the application appropriate for your operating system.

• Install the desired model from the Ollama library
  You can explore available models from the Ollama Library (e.g., llama2:13b, llama2:7b, mistral:7b, etc.).

To download and run a model (e.g., llama2:7b), use the following command:

ollama run llama2:7b

In Visual Studio, Go to Tools → NuGet Package Manager → Package Manager Console. Run these command:

Install-Package OllamaSharp -Version 5.3.6

In Visual Studio Code, Open terminal in VS Code. Run these commands:

dotnet add package OllamaSharp --version 5.3.6

Add the following settings to the ~/Program.cs file in your Blazor Server app.

using Microsoft.Extensions.AI;
using OllamaSharp;
using Syncfusion.Blazor;
using Syncfusion.Blazor.AI;
...
var builder = WebApplication.CreateBuilder(args);
...
builder.Services.AddSyncfusionBlazor();

// Define the name of the AI model to use from Ollama (e.g., llama2:13b, mistral:7b, etc.)
string aiModel = "llama2:7b";

// By default, Ollama runs on port 11434, you can also customize this port manually.
HttpClient httpClient = new HttpClient
{
    BaseAddress = new Uri("http://localhost:11434"), // Ollama server address
    Timeout = Timeout.InfiniteTimeSpan // Supports extended processing time for AI responses
};

// Initialize the chat client using the Ollama API and the specified model
IChatClient chatClient = new OllamaApiClient(httpClient, aiModel);
builder.Services.AddChatClient(chatClient);
builder.Services.AddSingleton<IChatInferenceService, SyncfusionAIService>();

var app = builder.Build();
...

NOTE

Running Ollama locally may lead to slower response times due to system resource usage.
To accommodate this, you can configure the Syncfusion Smart PDF Viewer to disable timeout for AI assist view operations by setting the timeout to 0.

To Check the Installed Model and Its Details in Ollama

• To verify which models are currently installed and available on your local Ollama server (example: running on port 11434), run the following command in your terminal or command prompt:

curl http://localhost:11434/api/tags

Add stylesheet and script resources

The theme stylesheet and script can be accessed from NuGet through Static Web Assets. Include the stylesheet reference in the <head> section and the script reference at the end of the <body> in the ~/Components/App.razor file as shown below:

<head>
    ....
    <!-- Syncfusion Blazor Smart PDF Viewer control's theme style sheet -->
    <link href="_content/Syncfusion.Blazor.Themes/fluent2.css" rel="stylesheet" />
</head>

<body>
    ....
    <!-- Syncfusion Blazor Smart PDF Viewer control's scripts -->
    <script src="_content/Syncfusion.Blazor.SfSmartPdfViewer/scripts/syncfusion-blazor-sfsmartpdfviewer.min.js" type="text/javascript"></script>
</body>

NOTE

Check out the Blazor Themes topic to discover various methods (Static Web Assets, CDN, and CRG) for referencing themes in your Blazor application. Also, check out the Adding Script Reference topic to learn different approaches for adding script references in your Blazor application.

Add Syncfusion^® Blazor Smart PDF Viewer component

Add the Syncfusion^® Blazor Smart PDF Viewer component in the ~Pages/Home.razor file.

@page "/"

<SfSmartPdfViewer Height="100%" Width="100%" DocumentPath="https://cdn.syncfusion.com/content/pdf/http-succinctly.pdf">
</SfSmartPdfViewer>

• Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. This will render the Syncfusion^® Blazor Smart PDF Viewer component in your default web browser.

NOTE

View Sample in GitHub.
