Configuration file options

• max_color_only (integer)
  • Default: 0 (no effect)
  • when set to 1, only max from R G B is passed, other values are changed to 0

• r_min (integer)
  • Default: -1 (no filter)
  • R minimal threshold value
• g_min (integer)
  • Default: -1 (no filter)
  • G minimal threshold value
• b_min (integer)
  • Default: -1 (no filter)
  • B minimal threshold value
• grey_min (integer)
  • Default: -1 (no filter)
  • GREY minimal threshold value

• r_max (integer)
  • Default: -1 (no filter)
  • R maximal threshold value
• g_max (integer)
  • Default: -1 (no filter)
  • G maximal threshold value
• b_max (integer)
  • Default: -1 (no filter)
  • B maximal threshold value
• grey_max (integer)
  • Default: -1 (no filter)
  • GREY maximal threshold value

• r_above (integer)
  • Default: 255
  • new value for each R value above the R maximal threshold
• g_above (integer)
  • Default: 255
  • new value for each G value above the G maximal threshold
• b_above (integer)
  • Default: 255
  • new value for each B value above the B maximal threshold
• grey_above (integer)
  • Default: 255
  • new value for each RGB value above the GREY maximal threshold

• r_below (integer)
  • Default: 0
  • new value for each R value below the R minimal threshold
• g_below (integer)
  • Default: 0
  • new value for each G value below the G minimal threshold
• b_below (integer)
  • Default: 0
  • new value for each B value below the B minimal threshold
• grey_below (integer)
  • Default: 0
  • new value for each RGB value below the GREY minimal threshold

• r_passed (integer)
  • Default: -1 (no change)
  • new value for each R value between the R minimal and the R maximal thresholds
• g_passed (integer)
  • Default: -1 (no change)
  • new value for each G value between the G minimal and the G maximal thresholds
• b_passed (integer)
  • Default: -1 (no change)
  • new value for each B value between the B minimal and the B maximal thresholds
• grey_passed (integer)
  • Default: -1 (no change)
  • new value for each RGB value between the GREY minimal and the GREY maximal thresholds (-1 = no change, -2 = RGB->GREY conversion)
  • this setting overrides other *_passed settings
