Class CurvResource


  • public class CurvResource
extends AdjustmentLayerResource

    Class CurvResource. Resource of Curves Adjustment Layer 1 byte - 0 if use curves, 1 if used pixels on map if 0 then: 2 bytes - short. Default is 1 4 bytes - int. Used only last byte by bit. First bit is for 1 channel, the Fourth bit for 4 channel for example 2 bytes - short points count 4 bytes * count of point - points of curve 2 short: first position, second height 4 bytes - word "Crv " 2 bytes - short default is 4 for Curves 4 bytes - int. Default is 1 4 bytes - point count 4 bytes * point count - points of curve 2 short: first position, second height 0-4 bytes - Leading to be fold for four if 1 then: 2 bytes - short. Default is 1 4 bytes - int. Used only last byte. One channel is in one bit. First bit is for 1 channel, the Fourth bit for 4 channel for example 256 * count of changed channels - ordered values of channel in range 0 - 255 4 bytes - word "Crv " 2 bytes - short. Default is 3 for pixels on map 4 bytes - int Channel count (2 + 256) bytes - short 2 for channel index, 256 is ordered values of channel in range 0 - 255
