[udhayaprakash]

Hi,

I was trying similar kind of approach to generate rendtions for my image but it was creating wrong width and height , 

expecetd width and height 1600 , 800 
but i got 1280X639 , what could be the possible issue , I tried passing the thhumbnail config also but no use .
Any sugesstions on this ?

@Properties({

@property(name = "process.label", value = "Custom Image Rendition Process") })

@component

@service

public class CustomImageRendition implements WorkflowProcess {

  private static final Logger logger = Logger.getLogger(CustomImageRendition.class.getName());

  @reference

  protected ResourceResolverFactory resourceResolverFactory;

  @reference

  RenditionMaker renditionMaker;

  @reference

  AssetHandler assetHandler;

  ResourceResolver resourceResolver;

  @Override

  public void execute(WorkItem workItem, WorkflowSession session, MetaDataMap args) throws WorkflowException {

  try

      {

    String assetPath = null;

    // Get the resource resolver using system user and user mapper service

        Map<String, Object> param = new HashMap<String, Object>();

        param.put(ResourceResolverFactory.SUBSERVICE, "getResourceResolver");

          resourceResolver = resourceResolverFactory.getServiceResourceResolver(param);

          String payloadString = workItem.getWorkflowData().getPayload().toString();

       logger.info("payload path"+payloadString);

        // convert the payload path into a Resource

        Resource damResource = resourceResolver.resolve(payloadString);

        if (damResource != null){

        logger.info("the damResource is exists .. "+damResource);

        // further convert the resource into Dam asset

        Asset damAsset =  damResource.adaptTo(Asset.class);

        if(damAsset !=null)

        {

        logger.info("dam asset exists .. "+ damAsset);

        // create a Rendition Template using Rendition Maker Api and give the width, height, quality, mimietype for your template

        int width = 250;

        int height = 250;

        int quality = 100;

            String mimeType = "image/jpeg";

            String[] mimeTypesToKeep ={ "image/jpeg","image/png"};

            RenditionTemplate renditionTemplate = renditionMaker.createWebRenditionTemplate(damAsset, width, height, quality,

                     mimeType,mimeTypesToKeep);

            // Using the rendition template created above , generate the renditions

        List<Rendition> renditionList = renditionMaker.generateRenditions(damAsset, renditionTemplate);

        // using Asset Handler Api create thumbnails using the rendition for the asset.

        Collection<ThumbnailConfig> configs = null;

        for(Rendition rendition : renditionList ){

        assetHandler.createThumbnails( damAsset, rendition, configs);

        }

        // Just to check if our rendition got added.

        for (Rendition rendition2 : damAsset.getRenditions()) {

        logger.info(rendition2.getName() + " " + rendition2.getPath()+"\n");

      }

        resourceResolver.commit();

        }

        }

      }

  catch(LoginException  |IOException e){

  e.printStackTrace();

  }

  }

}

hi @udhayaprakash, if your goal is to create renditions without any customization to their output, such as simple resizing, I recommend checking out the Thumbnail Process step, which is part of the "DAM Update Asset" workflow. This process allows you to define both thumbnails and web-enabled images.

The advantage of this solution is that it doesn't require any code for development or maintenance, making it a better option.

if you're in AEM as a Cloud Service, have a look at Integrate with AEM Processing Profiles

You don’t need to create a custom code to create an image rendition. You can use available aem dam renditions to create the desired rendition both on aem on-prem and ams but in aem cloud you need to create image processing profile.

the renditions image should not be going to be larger than the original image.
