How can we regenerate document preview and thumnails

[Jitender Dhiman, geändert vor 9 Jahren.]

Hi team,

Previously we were using image magick for preview generation but due to some reason it stopped working and now we have disabled it.

But documents uploaded in between are not having previews and thumnails..

How can we regenerate thumnails and previews of them.

Thanks in advance

Well, thumbnails and previews come from imagemagick, ghostscript, and xuggler. Disabling those will disable your ability to generate some previews and thumbnails.

For those you can generate, when you click into the document in docs and media (or viewer), the thumbnail will be regenerated.

thank you so much David.... but is there any other to do this programically (except clicking on document)

Yes, I remember creating a portlet that had a single button but, when clicked, would invoke the logic to rebuild each thumbnail image. I'll see if I can dig it up.
