Does getRGB account for the Alpha channel? If not what should i use instead of getRGB?

I am trying to load a Sprite Sheet into an array with transparent backgrounds on the sprites, and i want it to keep the transparency instead of setting it to 0(black). Will getRGB work for this?

public SpriteSheet(String path) {
      this.path = path;
      loadSheet();
   }
   
   private void loadSheet() {
      try {
         BufferedImage image = ImageIO.read(SpriteSheet.class.getResource(path));
         this.w = image.getWidth();
         this.h = image.getHeight();
         pixels = new int[w * h];
         image.getRGB(0, 0, w, h, pixels, 0, w);
      } catch (IOException e) {
         e.printStackTrace();
      }
   }

Hi

According to Stack Overflow
getRGB()
has the alpha channel. Link: http://stackoverflow.com/questions/10726594/bufferedimage-getrgbx-y-does-not-yield-alpha

Either wandering the forum or programming. Most likely the latter Smiley
