Me whakaatu koe i tētahi tae tā ki runga mata? Mā te huri CMYK ki RGB ka whiwhi koe i te rite rama o ō ōrau inki — ko ngā uara e taea ana e tētahi mata, mockup, rānei te whārangi ipurangi te whakaatu.
Me pēhea te hurihanga CMYK ki RGB
- Huria ngā paihikara e whā katoa ki ngā rapanga i waenga i te 0 me te 1.
- Whakamahia te wāhanga key tuatahi: ka whānuihia ia hongere e (1 − K).
- Tātaihia R = 255 × (1 − C) × (1 − K), G = 255 × (1 − M) × (1 − K) me B = 255 × (1 − Y) × (1 − K).
- Porohia ia hongere kia tau ki te tau katoa i waenga i te 0 me te 255.
Tauira mahi
He tatauranga. He nui ake ngā tae e taea e te mata te whakaatu i aua e taea e te inki, nō reira ka titiro ake te RGB ki te māmā me te whāiti ake i te tā.
Ngā whakamārama mō CMYK me RGB
He aha te CMYK?
He tauira pēne e whā te CMYK e whakamahia ana i te tā: cyan, magenta, kōwhai me te kī (pango), ia kotahi hei ōrau mai i te 0 ki te 100. Ka tango e te mīhini te rama, kāore e tuku ana, nō reira he iti ake ngā tae ka āhei i te CMYK i te mata — koia te take ka āhua mēnā he kōwhai whakaroto ngā tae mata i te wā e tāia ana.

He aha te RGB?
Kei te whakamārama a RGB i tētahi tae hei toru ngā hongere o te rama — whero, karaka me kikorangi — ia kotahi mai i 0 ki 255. Ka whakaata i te mahi o ngā mata: ka riro ko te ma mēnā e toru katoa kei te 255, ko te pango mēnā e toru kei te 0. He pai te RGB mēnā me tatau koe ki tētahi tae, ā, ka tāpirihia e rgba() te marama ārai.
