Why does Slick-util's Texture.getWidth() and Texture.getHeight() return a float?

I'm making a game with LWJGL (and Slick-util) and I was going to use the Texture.getWidth() and Texture.getHeight() to get the width and height of a Texure object, instead of typing in the width and height manually, but I found out that those functions returns a float. I want to get the width of the Texture in pixels, but the function returns a float, so I'm unsure what "unit" the function actually returns, because pixels must be int (not floats, because you cant render the half of a pixel with one color and the other half of it with another color).

Can I just cast them to int and it's fine?

Solution

  • Sorry for the quick asking, I found the answer by looking in the javadocs for Slick-util.

    To get the size of the original image, use Texture.getImageWidth() and Texture.getImageHeight().
