[Lcms-user] LCMS python

[Gonzalez C. J. <jor...@hp...>]

I would like to use the LCMS with python, but when I want to call the function cmsDoTransform the following error appears: TypeError: in method 'cmsDoTransform', argument 2 of type 'void const *'
What I am sending to the cmsDoTransform si the following:

array = [255,255,255]
labColor = lcmsF.transformToLab(array,profileInURL,"RGB","perceptual")

---------------

def transformToLab(inputColor, profileInURL, formatIn, intent, BPC = True):
    LabColor = []

    labProfile = lcms.cmsCreateLab4Profile(lcms.cmsCIExyY())
    inputProfile = lcms.cmsOpenProfileFromFile(profileInURL, "r")

    if(formatIn == "RGB"):
        inType = lcms.TYPE_RGB_DBL
    elif(formatIn == "CMYK"):
        inType = lcms.TYPE_CMYK_DBL

    if(intent == "perceptual"):
        m_intent = lcms.INTENT_PERCEPTUAL

    if(BPC):
        m_BPC = lcms.cmsFLAGS_BLACKPOINTCOMPENSATION
    else:
        m_BPC = 0
    transform = lcms.cmsCreateTransform(inputProfile, inType, labProfile, lcms.TYPE_Lab_DBL, m_intent, m_BPC)

    lcms.cmsDoTransform(transform,inputColor, LabColor, DIM_OUT)
    return LabColor

How I am supposed to do it?

Thanks,
