Finding dimensions of a .gif file

Question

I'm looking for a way to find the pixel dimensions of a .gif file in Java.

Will I have to convert one of the images from the gif to a BufferedImage and get it from there or is there a simpler way?

Using ImageIO doesn't work because I need to use ImageIcons to draw a gif using Swing. Here's how I'm drawing it.

attackImage = new ImageIcon("assets/Attacks/EnergyAttack.gif").getImage();
g.drawImage(attackImage, getX() + 20, getY(), null);

@MTCoster no because this specifically relates to gifs, not jpegs/pngs — Ferex, Aug 16 '19 at 16:23

I quote you:

Have you tried using ImageIcon.getIconHeight and ImageIcon.getIconWidth? Additionally, if you have a fixed-size view, you might consider using ImageIcon.getImage followed by Image.getScaledInstance.

Since you already have an ImageIcon instance, you can simply use its getIconHeight() and getIconWidth() methods to get these values:

ImageIcon attackImage = new ImageIcon("assets/Attacks/EnergyAttack.gif");
int attackImageHeight = attackImage.getIconHeight();
int attackImageWidth = attackImage.getIconWidth();
g.drawImage(attackImage.getImage(), getX() + 20, getY(), null);
