CurvResource Class
Summary: 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
