Get image size thru thru code

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?

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

ex.

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!

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

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();

}

Use the following code in HTL/Java per your use case -
