2. Image Options

• If does not contain FUJIFILMOPTION: 0
• If contains CLEARALL, start as 16 else 0
• If contains FORCEPRT i |= 32
• If contains NOREPRINT i |= 64
• If contains NOSAVE i |= 128

int indexOf = toUpperCase.indexOf("LUT"); if (indexOf != -1) { int parseInt; try { parseInt = Integer.parseInt(toUpperCase.substring(indexOf + 3, indexOf + 4)); } catch (NumberFormatException e) { parseInt = 0; } i |= parseInt; ```
