  • Method Details

    • getWidth

      public final int getWidth()
      Retrieves the current width of the GImage in pixels
      Returns:
      width in px

    • getHeight

      public final int getHeight()
      Retrieves the current height of the GImage in pixels
      Returns:
      height in px

      Returns:
      height in px

    • scale

      public void scale(double scale)
      Symmetrically scales an image.
      • If scale is less than 1 then the image will be reduced.
      • If scale is 1, then nothing noticeable should happen to the image.
      • If scale is more than 1 then the image will be bigger.
      Parameters:
      scale - scale quotient

    • scale

      public void scale(double sx, double sy)
      Scales an image.
      • If scaleX/Y is less than 1 then the image will be reduced.
      • If scaleX/Y is 1, then nothing noticeable should happen to the image.
      • If scaleX/Y is more than 1 then the image will be bigger.
      Note: Scaling is not accumulative, it always refers to the original image.
      Parameters:
      sx - Horizontal scale
      sy - Vertical scale
