How to cache images on Azure storage

[srdjo]

Hi,

I am trying to configure ImageSharp.Web with AzureBlobStorageImageProvider and all is working fine but is there a way to cache images on the same Azure storage and not in the local file system ?

I am migrating my ASP.Net MVC app to Asp.net Core 3.1 app with ServiceStack and Nuxt.js front end that is hosted on Azure and I would like to prevent cache files clogging my application.

Also is there a way to make named presets like there was in ImageProcessor.Web ?

Best regards.

You have to implement and register your own IImageCache

You can use the PhysicalFileSystemCache for inspiration.

Also is there a way to make named presets like there was in ImageProcessor.Web ?

There's two ways:

1. Implement and register your own IImageWebProcessor that captures a single query and converts it into a predefined process.
2. Use ASP.NET Core TagHelpers to render the correct querystring command based upon your own application logic.

@srdjo An official blob storage cache is coming with V1. Stay tuned!

Can you give me more information on how to implement and register processors and providers ?

I just need to enable Entropycrop since I used it in ImageProcessor.Web

Thanks in advance

The best way to do it is to copy how existing processors do it, you can find the source code here. Registration is documented in the readme and docs.
