Unoda kuratidza ruvara rweprinti pascreen? Kushandura CMYK kuRGB kunokuunzira equivalent yemwenje wemaphesenti einki — mavalue anooneka pamonitor, mockup kana web peji.
Maitiro ekuverenga CMYK kuenda ku RGB
- Shandura ese mana percentages kuita mafractions pakati pe0 ne1.
- Shandisa key component kutanga: channel imwe neimwe inoderedzwa ne(1 − K).
- Verenga R = 255 × (1 − C) × (1 − K), G = 255 × (1 − M) × (1 − K) uye B = 255 × (1 − Y) × (1 − K).
- Komberedza channel imwe neimwe kuita whole number pakati pe0 ne255.
Muenzaniso wakashanda
Kungofungidzirwa. Screen inogona kuratidza mavara akawanda kupfuura anobva muinki, saka mhedzisiro yeRGB inowanzoita yakajeka uye ine saturation yakakwira kupfuura chakadhindwa.

Chii chinonzi RGB?
RGB inotsanangura ruvara sezviteshi zvitatu zverambi — red, green ne blue — imwe neimwe kubva pa 0 kusvika 255. Inoratidza maitiro anoshanda masikirini: ese matatu pa255 anopa chena, ese pa0 anopa nhema. RGB ndiyo sarudzo yakakodzera paunoda kuverenga nemavara, uye rgba() inowedzera kuvharika pamusoro.
- Syntax:
- rgb(R, G, B)
- Range:
- 0–255 per channel
- Yakanakira:
- code, canvas, transparency with rgba()
