Hi all,
I am wondering if there's a wiser way to get the image object's width and
height, please advise.
Here is my idea:

new ImageIcon(image_object).getIconWidth();
new ImageIcon(image_object).getIconHeight();

If you mean wiser in the sense that you don't need to load the image into
memory.
Then yes, if that is all you need to do then use the ImageIO package

specifically You need an ImageReader for the image format you have:

javax.imageio.ImageIO.getImageReadersByFormatName(String formatName)

and then you use the two methods:

javax.imageio.ImageReader.getHeight()
javax.imageio.ImageReader.getWidth()

These will read only as much of the file as is necessary to determine these
attributes.
