The problem creates a thumbnail after insertion

robertD — Mon, 20 Sep 2021 05:49:57 GMT

Hi,

I use alfresco 7.1.0 with embedded ImageMagick 7.0.10. In global.properties I have system.thumbnail.generate=true. In Tomcat I have file thumbnail-service-context.xml and I use CMIS connector.

Alfresco does not automatically create a thumbnail. If I open a folder in Alfresco UI, then I will wait a few seconds to create a preview only, then do I have a preview in CMIS.

Can you please advise me what is wrong, if the thumbnail does not create itself after insertion?

Thanks,
Robo

Legacy transformation is no longer available with ACS7. You have to use local transformation service.

Checkout the steps to setup local tr service here: https://hub.alfresco.com/t5/alfresco-content-services-forum/alfresco-comunity-7-zip-haven-t-alfresco-pdf-renderer-into/m-p/307186#M24293

The approach you are using is also deprecated. Use the new async RenditionService2.
