Image resizing for Optimizely CMS 12 doesn't work

Vote:
 

Hi,

Short info: CMS 12.3, DXP is used (tested on "Integration" only for now), Azure Blob storage is configured.

I am trying to configure PictureRenderer.Optimizely in order to generate <picture> elements. The html looks good, but the image is not resized.

Example of html:

<picture>
<source srcset="/siteassets/test-folder/0101f87e7447b76181127d7a3d66ff66.jpeg?width=400&amp;quality=80 400w, /siteassets/test-folder/0101f87e7447b76181127d7a3d66ff66.jpeg?width=800&amp;quality=80 800w, /siteassets/test-folder/0101f87e7447b76181127d7a3d66ff66.jpeg?width=1040&amp;quality=80 1040w" sizes="(max-width: 640px) 400px, (max-width: 1200px) 800px, 1040px">
<img alt="AltTextImage" src="/siteassets/test-folder/0101f87e7447b76181127d7a3d66ff66.jpeg?width=1040&amp;quality=80" loading="lazy">
</picture>

As I understand the relations of the modules is the following one:

  1. PictureRenderer.Optimizely renders HTML (basing of the Picture profile) and it depends on the module (#2) below
  2. Baaijte.Optimizely.ImageSharp.Web re-uses module #3 for Optimizely. Most of the configuration in Startup.cs is related to this module.
  3. SixLabors.ImageSharp.Web - the module which allows image manipulation via URL based commands.

    My dependencies:



    Part of ConfigureServices method.

    // Azure Blob
    services.AddAzureBlobProvider(options =>
    {
    	options.ConnectionString = _configuration.GetConnectionString("EPiServerAzureBlobs");
    	options.ContainerName = BlobContainerName;
    });
    
    // Configuration of Baaijte.OptimizelyImageSharp.Web
    services.AddImageSharp()
    	.Configure<AzureBlobStorageCacheOptions>(options =>
    	{
    		options.ConnectionString = _configuration.GetConnectionString("EPiServerAzureBlobs");
    		options.ContainerName = BlobContainerName;
    	})
    	.ClearProviders()
    	.AddProvider<BlobImageProvider>()
    	.SetCache<AzureBlobStorageCache>();


    My Configure method (only the last row in the method is related to this task).

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
    	/* geta-notfoundhandler begin */
    	app.UseNotFoundHandler();
    	/* geta-notfoundhandler end */
    
    	if (env.IsDevelopment())
    	{
    		app.UseDeveloperExceptionPage();
    	}
    
    	app.UseStaticFiles();
    	app.UseRouting();
    	app.UseAuthentication();
    	app.UseAuthorization();
    
    	app.UseEndpoints(endpoints =>
    	{
    		endpoints.MapContent();
    		endpoints.MapControllers();
    		endpoints.MapRazorPages(); /* required for "geta-notfoundhandler" as well */
    	});
    
    	// Add the image processing middleware.
    	app.UseBaaijteOptimizelyImageSharp();
    }

I looked through example: https://github.com/SixLabors/ImageSharp.Web/blob/main/samples/ImageSharp.Web.Sample/Startup.cs

and tried to add ".AddProcessor<ResizeWebProcessor>()" explicitly, but it didn't help.

It is worth to mention that readme file for module Baaijte.Optimizely.ImageSharp.Web contains statement : DO NOT add other SixLabors.ImageSharp.Web settings!!
So, I haven't tried to use any other options...

Will be glad to know if somebody uses the same modules and has a working configuration. Thank you in advance.

Best regards,

Maxim

Hi again,

It looks that I found a root cause. Decided to check the example (https://github.com/SixLabors/ImageSharp.Web/blob/main/samples/ImageSharp.Web.Sample/Startup.cs) one more time and found that I have a wrong position of image processing middleware.

So, final version of Configure method is:

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
	/* geta-notfoundhandler begin */
	app.UseNotFoundHandler();
	/* geta-notfoundhandler end */

	if (env.IsDevelopment())
	{
		app.UseDeveloperExceptionPage();
	}

	// Add the image processing middleware.
	app.UseBaaijteOptimizelyImageSharp();

	app.UseStaticFiles();
	app.UseRouting();
	app.UseAuthentication();
	app.UseAuthorization();

	app.UseEndpoints(endpoints =>
	{
		endpoints.MapContent();
		endpoints.MapControllers();
		endpoints.MapRazorPages(); /* required for "geta-notfoundhandler" as well */
	});
}

Hi Maxim, 

I tried same approach but getting error on DXP. 

Do you have any suggestion how to fix it? - Thanks!

@ErikHenningson - Have you faced similar issue on DXP?
Vote:
 

One thing we found was that in addition to adding the app.UseBaaijteOptimizelyImageSharp(); middleware early in the Configure() method, we also had to add services.AddBaaijteOptimizelyImageSharp(); before configuring the blob and caching provider options in the ConfigureServices() method.

Hi @Daniel

I tried same way, here is the code sample but no luck.

 public void ConfigureServices(IServiceCollection services)
  {
            services.AddBaaijteOptimizelyImageSharp();           
            if (!_webHostingEnvironment.IsDevelopment())
            {
               services.AddCmsCloudPlatformSupport(_configuration);
            }          
            
            services.AddMvc();
            services.AddSite();
            services.AddCms();        
            services.AddImagePointEditor();
            services.AddEmbeddedLocalization<Startup>();
            services.Configure<AppSettings>(_configuration.GetSection("AppSettings"));
}

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }

            app.UseBaaijteOptimizelyImageSharp();

            app.UseRouting();
            app.UseAuthentication();
            app.UseAuthorization();     
            app.UseSession();
 }

Hi Sanjay. You need have slightly different config when running on you local machine (storing the blobs in the file system) compared to when running in Azure (storing the blobs in Azure storage).
Take a look at the config needed for DXP here: https://github.com/vnbaaij/Baaijte.Optimizely.ImageSharp.Web#configuration-for-use-with-dxp

Hi Erik,
I have configured DXP settings and tried but no luck getting similar error and noticed using DXP setting, when I upload the files in media assets these are not showing in Microsoft Azure Storage Explorer under mysitemedia container.
Erik Henningson - Sep 02, 2022 13:35
Seems to me that your solution isn't properly configured for Azure? Storing the files as blob in a container is standard functionality, and has nothing to do with PictureRenderer or ImageSharp.
Contact support if this is a DXP solution.
Sanjay Kumar - Sep 02, 2022 14:03
But when I roll back BaaijteOptimizelyImageSharp changes then it works and I am able to see images loaded in mysitemedia .
