DAM thumbnail generation

[Former Community Member]

Hi,

1. Is it possible to generate thumbnail for word documents and excel without writing any custom workflow/servlet?

2. I have modified the update asset workflow to generate custom rendition of thumbnails (Added thumbnail arguments 120:120:false under Thumbnail process step). But when I upload image under rendition tabs in DAM, I do not see my custom thumbnail rendition getting generated. Is there a way to generate custom thumbnail rendition when we upload image manually.

Regards,

To generate a thumbnail for these assets - you need to write a DAM Handler. Within the handler - you can use DAM APIs (com.day.cq.dam.api) to create a thumbnail. To get you up and running with how to write a custom DAM Handler for AEM - see this article: 

Creating a Custom AEM Dam Media Handler

Hope this helps...

Hello @smacdonald2008 ,

I want to update the thumbnail for the expired assets.All my expired assets are in one folder. Running an scheduler to check the expiry date and moving that to archive folder.

I just want to apply watermark to the images. As applying watermark is creating a new rendition, looking for a way to apply watermark images as a thumbnail.

Can you please give me the solution, how i can approach this requirement..

Thanks in advance
