-/**
- * Instances of this class describe the color data used by an image.
- * <p>
- * Depending on the depth of the image, the PaletteData can take one
- * of two forms, indicated by the isDirect field:
- * </p>
- * <dl>
- * <dt>
- * <em>isDirect is false</em>
- * </dt>
- * <dd>
- * If isDirect is <code>false</code>, this palette is an indexed
- * palette which maps pixel values to RGBs. The actual RGB values
- * may be retrieved by using the getRGBs() method.
- * </dd>
- * <dt>
- * <em>isDirect is true</em>
- * </dt>
- * <dd>
- * If isDirect is <code>true</code>, this palette is a direct color
- * palette. Instead of containing RGB values, it contains red,
- * green and blue mask and shift information which indicates how
- * the color components may be extracted from a given pixel.
- * This means that the RGB value is actually encoded in the pixel value.
- * <p>
- * In this case, the shift data is the number of bits required to shift
- * the RGB value to the left in order to align the high bit of the
- * corresponding mask with the high bit of the first byte. This number
- * may be negative, so care must be taken when shifting. For example,
- * with a red mask of 0xFF0000, the red shift would be -16. With a red
- * mask of 0x1F, the red shift would be 3.
