Hi there!
I'm looking for a better algorithm...
In a print project I must know if some page needs every CMYK separation or just
some;
I keep this info in a boolean list like [True, True, False, True] for C,M,K (no
Y plate).
But our workflow database needs a string like "CM0K" (plate letter or zero).
How can I convert this best?
Here is my code:
class ProcessColors:
_cmykMap = ['C', 'M', 'Y', 'K']
def __init__(self, C=False, M=False, Y=False, K=True):
self.werte = [C,M,Y,K]
def bool2str(self, werte=None):
"""converts a list of booleans to a CMYK color string,
e.g. [True, False, False, True] to 'C00K'"""
if not werte: werte = self.werte
for i in range(0,4):
if werte[i]:
werte[i] = self._cmykMap[i]
else:
werte[i] = '0'
return string.join(werte, '')
def str2bool(self, werte='000K'):
"""converts a CMYK color string to a list of booleans,
e.g. 'CM0K' to [True, True, False, True]"""
werte = list(werte)
for i in range(0,4):
if werte[i]==self._cmykMap[i]:
werte[i] = True
else:
werte[i] = False
return werte
I hope the same is possible without 'if' and 'for', perhaps some lambda+boolean
wizardry?
Best regards,
