How to make ImageSharp.Web to resize images from a local directory other then wwwroot

Question

I'm developing a Blazor server application and I'm trying to implement imagesharp.web (V.3.01)

I have to use a folder called "Uploads" (not inside wwwroot). I'm trying to use PhysicalFileSystemProviderOptions, setting the ProviderRootPath to the desired folder, but it is not working.

Can anyone help on this problem?

var pathToUploads = Path.Combine(Directory.GetCurrentDirectory(), "Uploads");
var pathToUploadsCache = Path.Combine(Directory.GetCurrentDirectory(), "Uploads", "is-cache");

builder.Services.AddImageSharp(options =>
    {
        options.BrowserMaxAge = TimeSpan.FromDays(7);
        options.CacheMaxAge = TimeSpan.FromDays(365);

    }).ClearProviders()
    .AddProvider<WebRootImageProvider>()
    .Configure<PhysicalFileSystemCacheOptions>(options =>
    {
        options.CacheRootPath = null;
        options.CacheFolder = pathToUploadsCache;
        options.CacheFolderDepth = 8;
    })
            .SetCache<PhysicalFileSystemCache>()
    .AddProvider<PhysicalFileSystemProvider>()
    .Configure<PhysicalFileSystemProviderOptions>(options=>
    {
        options.ProviderRootPath = pathToUploads;
        }); 

var app = builder.Build();



// Set Uploads folder
SD.ContentRootPath = app.Environment.ContentRootPath;
SD.UploadsFullServerPath = Path.Combine(app.Environment.ContentRootPath, configuration["UploadsFolder:Name"]);
SD.UploadsRequestPath = configuration["UploadsFolder:WebPath"];
SD.UploadsNameOnly = configuration["UploadsFolder:Name"];
SD.UploadsRootFolderName = configuration["UploadsFolder:RootFolderName"];
SD.UploadsRootFolderWebPath = configuration["UploadsFolder:RootFolderWebPath"];
app.UseImageSharp();

app.UseStaticFiles();

if (!Directory.Exists(SD.UploadsFullServerPath)
    || !Directory.Exists(Path.Combine(SD.UploadsFullServerPath, SD.UploadsRootFolderName)))
{
    Directory.CreateDirectory(Path.Combine(SD.UploadsFullServerPath, SD.UploadsRootFolderName));
}
app.UseStaticFiles(new StaticFileOptions
{
    FileProvider = new PhysicalFileProvider(
        Path.Combine(builder.Environment.ContentRootPath, SD.UploadsNameOnly)),
    RequestPath = SD.UploadsRequestPath
});

Did you manage to make it work? In my case setting the ProviderRootPath property of the PhysicalFileSystemProviderOptions class is not working. — arielbvargas, Jun 26 '23 at 19:53

Right after AddImageSharp define this method:

services.AddImageSharpCore(
            options =>
            {
                options.MaxBrowserCacheDays = 7;
                options.MaxCacheDays = 365;
                options.CachedNameLength = 8;
                options.OnParseCommands = _ => { };
                options.OnBeforeSave = _ => { };
                options.OnProcessed = _ => { };
                options.OnPrepareResponse = _ => { };
            })

Add UseWebRoot in your Program.cs class:

public static void Main(string[] args)
{
    var host = new WebHostBuilder()
        .UseKestrel()
        .UseWebRoot("myroot") // name it whatever you want
        .UseContentRoot(Directory.GetCurrentDirectory())
        .UseIISIntegration()
        .UseStartup<Startup>()
        .Build();

    host.Run();
}
