Crop an Image programatically in AEM

[Veena_Vikraman]

Hi

  I am trying to crop an image programatically

Resource res = resourceResolver.getResource("/content/dam/images/test.jpg");
Asset asst = res.adaptTo(Asset.class);
Resource dataResource = resourceResolver.getResource(res.getPath()+"/jcr:content/renditions/original/jcr:content");
Layer layer = ImageHelper.createLayer(currentNode.getSession(),asst.getCurrentOriginal().getPath());
log.error("LAYER**" + layer);
Rectangle rect = ImageHelper.getCropRect("0,0,100,100",res.getPath());
layer.crop(rect);

  But I am not able to do the same since I am getting null pointer exception , since the layer itself is null. Can I know where I am making a mistake

Thanks

Veena

Also, just verify if you are importing a right 'Layer' package.

See this community article - it talks about using this API:

Hope this helps.

Hi Scott,

   I followed the same article , but I am getting Null for  

Layer layer = ImageHelper.createLayer(currentNode.getSession(),asst.getCurrentOriginal().getPath());

Hi Bsloki

   I am using com.day.image.Layer

Hi Veena,

 Can you please debug or put sysout and check which exactly is coming as null.

It might be ImageHelper, Session or the path

can you post the exact stack trace...  the blog post uses ImageHelper.createLayer(dataResource)

asset.getCurrentOriginal() is deprecated - https://docs.adobe.com/docs/en/aem/6-0/develop/ref/javadoc/com/day/cq/dam/api/Asset.html#getCurrentO...()

Deprecated. Will be removed without replacement. The concept of current originals will henceforth be managed through versioning the asset upon modifying the original. Use getOriginal()instead.

Returns the Rendition representing the asset's rendition currently marked as the asset's unmodified, original version. A rendition is marked as the original of an asset via the existence of the propertycurrentOriginal on the asset's content node. The property contains the path of the rendition to be considered the original. E.g. /content/dam/geometrixx/banners/banner-mono.png/jcr:content/currentOriginal with value /content/dam/geometrixx/banners/banner-mono.png/jcr:content/renditions/myOriginal.
