RGB, ekwabizwa ngokuba Bomvu / luhlaza / luhlaza okwesibhakabhakangu- indlela yokuchonga umbala esetyenziswa ngabahloli beekhompyuter. Umbala ngamnye unexabiso lawo leRGB, kwaye oku kungenxa yomxube wale mibala mithathu ngokudibeneyo benza uhlobo lombala olujongileyo unetoni enye okanye enye. La maxabiso e-RGB anokusetyenziselwa izizathu ezahlukeneyo, kodwa ikakhulu kwabo basebenza Ushicilelo lweefoto kunye nemifanekiso, okanye banokudlala Imizobo, kwaye kubalulekile kwi Umyili wewebhu.
Into encinci eyaziwayo yakhe IMac Inkqubo yakho yokusebenza iza nemitha leyo inokuchonga i-RGB kunye nombala we-hexadecimal wepikseli yesikrini okanye endaweni yakho Iphepha lodonga onalo kwidesktop yakho, kwaye kwesi sifundo siza kukubonisa ukuba yenziwa njani.
Chonga ixabiso leRGB yayo nayiphi na ipikseli kwiscreen sakho seMac.
Nokuba uzama ukuguqula ifoto, kwaye kuya kufuneka utshintshe ithoni yombala nokuba ungene Adobe Photoshop o Pixelmator, okanye uzama ukwenza umzobo omncinci omncinci, ukwazi amaxabiso e-RGB yepikseli kwindawo esele ikhoyo kunokuba luncedo kakhulu ekufumaneni iziphumo zombala ozikhangelayo.
IMac yakho iza ixhotyiswe ngesixhobo esibizwa ngokuba 'Imitha yemibala yedijithali', kwaye unokufumaneka kwi Launchpad> Abanye kwidokodo (ungabona njani kumfanekiso ongentla).
Emva kokuqala isicelo, Ungatsala isikhombisi naphi na apho ufuna khona kwiscreen, kwaye izakubonisa umbono owandisiweyo wommandla okhombe kuwo, kwaye igxininisa ukuba yile nto kanye ulinganisa kuyo, apho ungakhona khetha iifomathi ezininzi njengomthonyama, I-P3, i-sRGB, i-generic RGB, i-Adobe RGB, yy L * a * b *.
Kulo mzekelo, ndilinganisa umbala RGB yenxalenye yentaba yePhepha lodonga eziza ngokwakhona kwidesktop ye OS X El Capitan.
Njengoko ubona, amaxabiso abomvu abomvu angama-88, aluhlaza angama-33, aluhlaza angama-40. Ungasebenzisa la maxabiso afanayo kwisicelo esifana nesi Adobe Photoshop o Pixelmator ukuvelisa imibala efanayo oyisebenzisela ukuhlela umfanekiso.
Uyifumana njani kwifomathi ye-hexadecimal.
Umboniso weRGB sisincoko se-iceberg kunye 'Imitha yemibala yedijithali' Ingasetyenziselwa ukufikelela kumaxabiso emibala ye-hexadecimal, aluncedo kwi abayili bewebhu abayisebenzisayo CSS y HTML rhoqo. Njengoyilo lwegraphic kunye nonjiniyela, kum kubalulekile, apho Ndihlala ndisebenzisa izandiso kwizikhangeli ukwenza lo msebenzi uyindinisa ube lula kum.
Ukutshintsha kumaxabiso Umgangatho weRGB wokugqibela ukuya kumaxabiso e-hexadecimal, kuya kufuneka ucofe isixhobo 'Imitha yemibala yedijithali' ukutshintsha imenyu yakho iye kweyakho, emva koko ucofe Bonisa > Ubonisa amaxabiso> Nge-hexadecimal system ukutshintsha amaxabiso kule fomathi.
Ukuphela.
Ngaphandle kokungabi yinto oza kuyisebenzisa yonke imihla, ngaphandle kweemeko ezithile, 'Imitha yemibala yedijithali' yeyona nto ilula kakhulu enayo i-OS X, kwaye endandingazukuyifumana de ndaqala ukukhangela iifolda zam zoncedo ngakumbi, yiyo loo nto bendifuna Yabelana nabo bonke abafundi be Soy de Mac. Xa ndiyifumene, ndaqala ukuyisebenzisa ngalo lonke ixesha lokuhlela imifanekiso, ikakhulu ngombala, yayihambelana nokuhlelwa kwemifanekiso endiyisebenzisa ngakumbi kule webhusayithi.
Unokuba nomdla kwezi zifundo:
-
Sebenzisa nasiphi na isicelo kwi-Mac yakho nokuba ayiveli kwiVenkile ye-Mac App.
-
Fikelela kwimbali yakho yokubrawuza ngonqumamo olulula lwekhibhodi.
Ukusetyenziswa koku kusebenza kunokusebenzisa lilinganiselwe, kunye nomsebenzisi oqhelekileyo kunokuba luncedo oluncinci, kunye neengcali kwi uyilo kunye namaphepha ewebhu Inokulinganiselwa, kodwa ayikaze ibuhlungu ukwazi oku kusebenza.
