Using below code, we can retrieve the image width and height in Java and use that in HTL

import com.day.cq.wcm.foundation.Image;

Image image = new Image(resource);

int imgWidth = 990; // Some default width

int imgHeight = 520;// Some default height

  try {

  if (image.getLayer(false, false, false) != null) {

  imgWidth = image.getLayer(false, false, false).getWidth();

  imgHeight = image.getLayer(false, false, false).getHeight();

}

As Ravi correctly points out - you can use Java to get the information that you require.

Thanks for the answers! But I think my question is not quiet direct.

I need to extract the img meta data (specifically height:width) to my ".html" file so that I can reference it.

if I must use java to do this, where will I write my java code?

that's where I want to extract asset size.

Thanks!

Still haven't figure out above problem.
here is a someple code of what I'm trying to achieve

ex.

Created my java file, complete but apparently, I can't populate the "Image(resource)" with "fileReference" from cq:file as to I'm getting an error. a work around?
