Height and Width of the Rendition of the Image in Java

[tc94524330]

Hi,

I am working a lot recently with Assets. I want to get dimensions of the image renditions for the image. I can get the size of the rendition using getSize() method but was not able to find any method to get dimensions or say length and width of the image. 

I can get the length and width of the original image from metadata tiff:ImageLength and tiff:ImageWidth but i am not seeing any information like this for renditions. 

Can anyone provide any suggestions on hoe to get dimensions of the renditions.

Thanks

Try this

public int getWidth() { Asset asset = this.getResourceResolver().getResource("imagepath").adaptTo(Asset.class); Rendition rendition = asset.getRendition("cq5dam.thumbnail.48.48.png"); try { BufferedImage bimg = ImageIO.read(rendition.getStream()); return bimg.getWidth(); } catch (Exception e) { } return 0; }

Hi 

You can also try, the AssetDetails class to get the details of a particular DAM Asset.

For e.g.,

Resource res = resourceResolver.getResource("<<path to resource>>"); 
AssetDetails assetDetails = new AssetDetails(res);
assetDetails.getHeight();
assetDetails.getWidth();
