, and getBaseImage
methods.

+ *
+ * int baseImageIndex;
+ * Image[] resolutionVariants;
+ *
+ * public CustomMultiResolutionImage(int baseImageIndex,

+ * this.resolutionVariants = resolutionVariants;
+ * }
+ *
+ * @Override
+ * public Image getResolutionVariant(float logicalDPIX, float logicalDPIY,
+ * float baseImageWidth, float baseImageHeight,
+ * float destImageWidth, float destImageHeight) {
+ * // return a resolution variant based on the given logical DPI,
+ * // base image size, or destination image size
+ * }
+ *
+ * @Override
+ * public List getResolutionVariants() {
+ * return Arrays.asList(resolutionVariants);
+ * }
+ *
+ * protected Image getBaseImage() {
+ * return resolutionVariants[baseImageIndex];
+ * }
