Color Space Transform
This sample source code illustrates the use of the
transformation between different image color spaces. The
sample code is based on Microsoft Visual Basic. The
Ilixis Developer's Corner does not warrant that the
sample source code. This sample source code is for
guidance and illustration purposes only.
' CMY values used are between 0 and 1
' All variables used are of data type DOUBLE
CMY to CMYK
Tmp = 1
If ( C < Tmp ) Then
Tmp = C
End If
If ( M < Tmp ) Then
Tmp = M
End If
If ( Y < Tmp ) Then
Tmp = Y
End If
C = ( C - Tmp ) / ( 1 - Tmp )
M = ( M - Tmp ) / ( 1 - Tmp )
Y = ( Y - Tmp ) / ( 1 - Tmp )
K = Tmp
CMYK to CMY
C = ( C * ( 1 - K ) + K )
M = ( M * ( 1 - K ) + K )
Y = ( Y * ( 1 - K ) + K )
