Method Detail

dimensionUnsignedWidth

public static @Unsigned int dimensionUnsignedWidth(Dimension dim)

Gets the unsigned width of a Dimension.

dimensionUnsignedHeight

public static @Unsigned int dimensionUnsignedHeight(Dimension dim)

Gets the unsigned height of a Dimension.

setUnsignedRGB

public static void setUnsignedRGB(BufferedImage b,
                                  int startX,
                                  int startY,
                                  int w,
                                  int h,
                                  @Unsigned int[] rgbArray,
                                  int offset,
                                  int scansize)

Sets rgb of BufferedImage b given unsigned ints. This method is a wrapper around setRGB(int, int, int, int, int[], int, int), but assumes that the input should be interpreted as unsigned.

getUnsignedRGB

public static @Unsigned int[] getUnsignedRGB(BufferedImage b,
                                             int startX,
                                             int startY,
                                             int w,
                                             int h,
                                             @Unsigned int[] rgbArray,
                                             int offset,
                                             int scansize)

Gets rgb of BufferedImage b as unsigned ints. This method is a wrapper around getRGB(int, int, int, int, int[], int, int), but assumes that the output should be interpreted as unsigned.
