Read Slick2D image as a pixel array?

Engines, Libraries and Tools
#1

I’d like to convert a org.newdawn.slick.Image to an array of pixel and read its RGB. I understand there’s getColor(x,y) but wouldn’t that be awfully slow?
I wrote this code, but I don’t know how to get RGB or even if this works as intended.


public byte[] getImagePixels(Image img) {
    return img.getTexture().getTextureData();
}

Another solution would be to convert img to a BufferedImage, but it seems impossible AFAIK.

Any help?
