In DamAdmin, select an asset, right click open it , there we have an option to upload custom thumbnail and renditions.

Same thing I need to do using java servlet for any type of asset.

Any help will be appreciated.

Thanks in Advance!!

Hi Satya

      You can add renditions to any image using AssetManager/Asset API . Please refer the below API for more help Asset ("The Adobe AEM Quickstart and Web Application.")

    A sample code might help Java Code Example

Thanks

Also for custom thumbnail we can use RenditionMaker or Asset Handler.

By RenditionMaker, we can associate an Asset "X" with Asset "Y" as a thumbnail.

// Create the Rendition Template for thumbnail
RenditionTemplate[] templates = createRenditionTemplates(tempThumbnailAsset);
// Generate thumbnail
renditionMaker.generateRenditions(asset, templates);

private RenditionTemplate[] createRenditionTemplates(Asset tempThumbnailAsset) {
        ThumbnailConfig[] thumbnails = new ThumbnailConfig[1];
        ThumbnailConfig thumbnail = new ThumbnailConfigImpl(48,48,false);
       
        RenditionTemplate[] templates = new RenditionTemplate[thumbnails.length];
        for (int i = 0; i < thumbnails.length; i++) {
            ThumbnailConfig thumb = thumbnails[i];
            templates[i] = renditionMaker.createThumbnailTemplate(tempThumbnailAsset,thumb.getWidth(),
                                thumb.getHeight(),thumb.doCenter());
        }
        return templates;
}
