DAM - Thumbnail not created for MS Word / XLSX assets

[Anwar_Sadat]

Hi,

When we upload a MS Word / Excel file to DAM, renditions and thumbnails are not created. Do I have to install any additional rendition utilities to make it work?

[Ratna_Kumar]

Hi Anwer,

Renditions & thumbnails will be created in DAM, that only be applicable to Graphics and not for MS Word / Excel file.

Hope this helps.

Thanks,
Ratna Kumar.

Hi 

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

Reference Link:- https://docs.adobe.com/docs/en/aem/6-0/develop/ref/javadoc/com/day/cq/dam/handler/standard/msoffice/...

//MSOfficeHandler

                    

Method Summary
ExtractedMetadata	extractMetadata(Asset asset)            This method is used by the ExtractMetadataProcess as part of the DAM Update Asset workflow during import or update of an asset.
BufferedImage	getImage(Rendition rendition)            This method retrieves the graphical representation of an Assets given Rendition.
BufferedImage	getImage(Rendition rendition, Dimension dim)            This method retrieves the graphical representation of an Assets given Rendition.
String[]	getMimeTypes()            This method returns the mime types a particular AssetHandler supports.

I hope this may help you.

Hi,

Please verify the path where your doc2pdf is present, i guess the path mentioned by is not correct.

Or add path of "doc2pdf" to PATH variable.

I hope this would be helpful.

Hi Kautuk - It works after the environment variables for the user (running AEM) is set to identify the path.
