ImageSharp.Web | : globe_with_meridians : High Performance Image Processing

I'm trying to map existing URL pattern to imagesharp.web to resize images.

I found a method to do that using URL rewrites. Other than that, Is there any standard way to map an existing URL pattern to an imagesharp.web URL pattern?

Existing URL Pattern:

Following the example code I'm attempting to hook up an ImageSharp.Web's AzureBlobStorageImageProvider but all image requests result in 404's. Any idea what I'm missing from my wiring-up?

Looking at the docs it seems the url convention should be https://localhost:44336/container-name/file-name.jpg?width=30

In my Startup.cs I have the following code:

Í have got imagesharp.web somewhat working. In the below it resizes the image but I can't get it to crop the image.

There is a second image it doesn't resize at all.

I'm trying to use ImageSharp.web for image processing using .net Core. After testing with an image stored in wwwroot, which successfully worked, I'm now trying to process images that are stored in Azure Blob storage and I'm not being successful, getting "The server responded with a status of 404 ()" (Not found).

I've followed the Sixlabors tutorials and I can't get an image result on:
https://localhost:44344/X/foto-teste10515264.jpg -> X is the container name.

I've got the following configurations in startup.cs:

I am getting the following error - sometimes - when trying to execute multiple statements using .NET 5.0, Dapper 2.0.78 with async and MSSQL Server:

System.InvalidOperationException: Invalid attempt to call NextResult when reader is closed. at Microsoft.Data.SqlClient.SqlDataReader.TryNextResult(Boolean& more)
at Microsoft.Data.SqlClient.SqlDataReader.NextResult() at Dapper.SqlMapper.GridReader.NextResult() in //Dapper/SqlMapper.GridReader.cs:line 414 at Dapper.SqlMapper.GridReader.ReadDeferred[T](Int32 index, Func 2 deserializer, Type effectiveType)+System.IDisposable.Dispose() at Dapper.SqlMapper.GridReader.ReadDeferred[T](Int32 index, Func 2 deserializer, Type effectiveType)+MoveNext() in //Dapper/SqlMapper.GridReader.cs:line 384 at System.Collections.Generic.List 1..ctor(IEnumerable 1 collection)
at System.Linq.Enumerable.ToList[TSource](IEnumerable`1 source)

It does not happen all the time. I suspect the SQL connection is being closed unintentionally. What can be wrong?

To debug I have tested the SQL statements and looked at the Execution Plan in SSMS - nothing here is flagged, i.e. proper indexes, primary keys are configured, it executes in very short time. SQL Server has

• 16 GB RAM
• SQL Server 2016 latest updates
• Intel Xeon E5-2630 v4 @ 2.2 GHz, 6 virtual processors.

Here is my code which is relatively simple.

I am using ImageSharp.Web to resize images on my ASP.NET Core 5.0 website.

To prevent DDoS (Distributed Denial of Service attacks), I would like to restrict the sizes that ImageSharp.Web can resize too.

For example I have an image with an original size of 800x400 (100kb) that I am resizing using the following:

I am migrating my project from Asp.Net MVC to ServiceStack Nuxt.js SPA and one thing that I used on MVC was ImageProcessor.Web to manipulate images on the fly

I am now trying to use ImageSharp.Web with Azure blob on ServiceStack Nuxt.js template.

I registered service in ConfigureServices

I am trying make an Azure function to resize images via a URL scheme, using a query string to return a resized image. I have looked at a few libraries. The most promising so far seems to be SixLabors ImageSharp solution which has middle-ware like ImageSharp.Web .

Unfortunately I can only find information on how to setup ASP.NET or WebAPI, similar to what is asked here ImageSharp.Web - resize image by querystring in Asp.Net Core 3.1 . I could code up something myself to handle the query parsing, but I was hoping there was already something existing so I do not need to roll my own.

Is there a library which lets me resize images via query string and runs in Azure function v2/v3?

I am trying to use ImageSharp.Web to resize images through querystring parameters eg: http://localhost:5001/content/photo/img.jpg?width=800&height=600

I created a new MVC Asp.Net Core 3.1 project, installed the packages and followed the Documentation

I tried the minimum configuration described and several variations, but it seems that the middleware is not intercepting the image request. I always get the original image and no error is triggered.

Am I missing something? What would be the minimum possible configuration for this feature?

Tks!
