Getting Started with BlazorImage

Ready to unlock the power of BlazorImage in your Blazor application? Here's a step-by-step guide:

Prerequisites

Make sure you have .NET 9.0 or a higher version installed. You can download it from the official .NET website.

Installation

Install the BlazorImage NuGet package by adding the following line to your project's .csproj file within the <ItemGroup> tag:

<PackageReference Include="BlazorImage" Version="1.0.1" />

Then, add the BlazorImage namespace to your _Imports.razor file:

@using BlazorImage

Setup Services

Open your Program.cs file and register the BlazorImage services within the ConfigureServices method:

builder.Services.AddBlazorImage();

Optional Endpoints (Development Stage)

During development, you can enable endpoints to manage the image cache. Add the following to your Program.cs file within the Configure method:

app.MapBlazorImage("/blazor/images");

Configuration

Customize BlazorImage to fit your specific needs by providing configuration options during service registration:

builder.Services.AddBlazorImage(options =>
{
    // Default quality for processed images (15-100). Default Value = 75
    options.DefaultQuality = 80;

    // Default file format for processed images (e.g., "webp", "jpeg"). Default is "webp"
    options.DefaultFileFormat = FileFormat.webp;

    // Path for storing processed images. Default is "_blazor"
    options.Dir = "_output";

    // Array of sizes for image configuration. Default [480, 640, 768, 1024, 1280, 1536] sizes
    options.ConfigSizes = new int[] { 640, 1024, 1280 };

    // Aspect ratio width for images. Default is 1.0
    options.AspectWidth = 1.0;

    // Aspect ratio height for images. Default is 1.0
    options.AspectHeight = 1.0;

    // Absolute expiration time relative to now for cached images. Default is 720 hours (30 days).
    options.AbsoluteExpirationRelativeToNow = TimeSpan.FromHours(720);

    // Sliding expiration time for cached images. Default is null.
    options.SlidingExpiration = null;
});

Usage in Your Components

Now you can start using the Image and Picture components in your Blazor pages and components.

Add Script and CSS

In your App.razor file, add the following script and link within the <head> or <body>:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Your Blazor App</title>
    <base href="/" />
    <link rel="stylesheet" href="css/app.css" />
    <link rel="stylesheet" href="YourProjectName.styles.css" />
    <link rel="stylesheet" href="_content/BlazorImage/BlazorImage.min.css" /> </head>
<body>
    <Routes />
    <script src="_framework/blazor.web.js"></script>
    <script src="_content/BlazorImage/BlazorImage.min.js"></script> </body>
</html>

Note: Replace YourProjectName with the actual name of your Blazor project.

Using the Image Component

The Image component is the primary way to display optimized images. Here's an example:

<Image Src="images/my-image.jpg"
       Alt="A beautiful landscape"
       Width="800"
       Height="600"
       LazyLoading="true"
       Title="Landscape View"
       CssClass="rounded-image"
       WrapperClass="image-container"
       Style="border: 1px solid #eee;"
       WrapperStyle="margin-bottom: 20px;"
       Quality="75"
       Format="FileFormat.webp"
       Sizes="(max-width: 768px) 100vw, 800px"
       EnableDeveloperMode="true" />

Using the Picture Component

For more advanced scenarios with multiple image sources (e.g., for different breakpoints or image formats), you can use the Picture component:

<Picture Src="images/main-image.jpg"
         Alt="Product Showcase"
         Width="1200"
         Height="900"
         LazyLoading="true"
         Title="Our Latest Product"
         CssClass="product-image"
         WrapperClass="product-wrapper"
         Style="box-shadow: 0 4px 8px rgba(0, 0, 0, 0.1);"
         WrapperStyle="text-align: center;"
         Quality="85"
         Format="FileFormat.avif"
         Sizes="(max-width: 600px) 100vw, (max-width: 1200px) 80vw, 1200px"
         CaptionClass="image-caption"
         Caption="Introducing our revolutionary product!"
         EnableDeveloperMode="false" />
