ImageBrowserController not working

[Adam]

The current examples available online to implement an ImageBrowserController by extending EditorImageBrowserController do not work. Is there any documentation available for hooking this up for .NET Core?

 

Thank you.

Hi Adam,

This is a known limitation discussed in this help article:

The Thumbnails view of the ImageBrowser is not supported because the System.Drawing namespace is not part of ASP.NET Core. However, a third-party library can be used for the server-side processing of images.

Hello,

Now the System.Drawing namespace can be installed via Nuget. ( Install-Package System.Drawing.Common )

I try to override the generate thumbnail method, but I cannot find example from the expected response. I try lot of version, but I cannot find the proper solution. The thumbnail image not showing, I see the loader forever.

This is one of my attempt (I use fix path for testing):

public override IActionResult Thumbnail(string path)
   {
       VirtualFileResult f = File("http://localhost:57939/TelerikUp/le_thumb.jpg", "application/octet-stream");
       return f;
   }

Hello Baracskai,

The Thumbnail configuration makes separate requests for each image and the response should contain the thumbnail image file. You could find an example implementation below: 

https://github.com/telerik/ui-for-aspnet-mvc-examples/blob/master/editor/database-image-browser/DatabaseImageBrowser/Controllers/ImageBrowserController.cs#L73

In addition, you might find useful the following article, as well as, our demo that shows the ImageBrowser in action:
