FFImageLoading.Maui - Fast & Furious Image Loading for .NET MAUI

Forked from the amazingly popular original FFImageLoading Library, this Compat version FFImageLoading.Compat aims to ease your migration from Xamarin.Forms to .NET MAUI with a compatible implementation to get you up and running without rewriting the parts of your app that relied on the original library.

This Maui version which merges all Transformations & SVG library parts into ONE and is migrated from FFImageLoading.Compat aims to fix some critical bugs and gives you a place to submit Maui releated issues.

The Most CRITICAL bugs it aims to fix：

1. [Fixed in 1.0.1][iOS] App Reloading Bug. (When a page contains a CachedImage which use local image file as LoadingPlaceholder, after tombstone the app to background and then recover it to forground, the app will be reloaded to the home page)
2. [Fixed in 1.0.3][iOS] Google webp format image support. (It works in Xamarin.Forms version, but not in FFImageLoading.Compat)
3. [Fixed in 1.0.7][Windows] Local images files will not show on Windows.

Thanks to the Original Authors: Daniel Luberda, Fabien Molinet & Redth.

Usage

1. Install NuGet package: FFImageLoading.Maui
2. Add .UseFFImageLoading() to your MAUI app builder.

public static class MauiProgram
{
    public static MauiApp CreateMauiApp()
    {
        var builder = MauiApp.CreateBuilder();
        builder
            .UseMauiApp<App>()
            .UseFFImageLoading()
            .ConfigureFonts(fonts =>
            {
                fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
                fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
            });

        return builder.Build();
    }
}

3. Add xmlns:ffimageloading="clr-namespace:FFImageLoading.Maui;assembly=FFImageLoading.Maui" to your MAUI Xaml page references.
4. Add <ffimageloading:CachedImage Source="xxx.jpg"></ffimageloading:CachedImage> to display image. Or add <ffimageloading:CachedImageView Source="xxx.jpg" Stroke="Red" StrokeThickness="1"></ffimageloading:CachedImageView> to display image with border.
5. If you're facing with some weird issues, try to clean the whole solution or upgrade your vs and maui to the latest version.

Support platforms

• Android
• iOS
• MacCatalyst
• Windows

Features

• .NET MAUI (iOS, MacCatalyst, Android, Windows) support
• Configurable disk and memory caching
• Multiple image views using the same image source (url, path, resource) will use only one bitmap which is cached in memory (less memory usage)
• Deduplication of similar download/load requests. (If 100 similar requests arrive at same time then one real loading will be performed while 99 others will wait).
• Error and loading placeholders support
• Images can be automatically downsampled to specified size (less memory usage)
• Fluent API which is inspired by Picasso naming
• SVG / WebP / GIF support
• Image loading Fade-In animations support
• Can retry image downloads (RetryCount, RetryDelay)
• Android bitmap optimization. Saves 50% of memory by trying not to use transparency channel when possible.
• Transformations support
  • BlurredTransformation
  • CircleTransformation, RoundedTransformation, CornersTransformation, CropTransformation
  • ColorSpaceTransformation, GrayscaleTransformation, SepiaTransformation, TintTransformation
  • FlipTransformation, RotateTransformation
  • Supports custom transformations (native platform ITransformation implementations)
