Ngokuvamile empilweni yethu sibhekene nesidingo sokunciphisa umdwebo noma isithombe. Isibonelo, uma ufuna ukubeka isithombe kusiphequluli esikrinini, noma uhlela ukusebenzisa isithombe esikhundleni somsindisi wesibuko kubhulogi.
Uma isithombe senziwe ngumchwepheshe, isisindo sayo singakwazi ukufinyelela ama-megabytes angamakhulu amaningana. Izithombe ezinjalo ezinkulu zinzima kakhulu ukugcina ikhompuyutha noma ukuzisebenzisa "ukujula" kumanethiwekhi omphakathi.
Yingakho, ngaphambi kokuthi ushicilele isithombe noma uyisindise kukhompyutha yakho, udinga ukunciphisa kancane.
Uhlelo oluhle kunazo zonke lokucindezela izithombe yi-Adobe Photoshop. Inzuzo yalo enkulu ikhona eqinisweni lokuthi awekho amathuluzi okunciphisa kuphela, kungenzeka futhi nokwandisa ikhwalithi yesithombe.
Ihlaziya isithombe
Ngaphambi kokunciphisa isithombe ku-Photoshop CS6, udinga ukuqonda ukuthi yini - ukwehla. Uma ufuna ukusebenzisa isithombe njenge-avatar, kubalulekile ukuthi ukulinganiswa okunye kuqaphele nokuthi ukulungiswa okudingekayo kugcinwa.
Futhi, isithombe kufanele sibe nesisindo esincane (mayelana nama-kilobytes ambalwa). Zonke izilinganiso ezidingekayo ongayithola kusayithi lapho uhlela khona ukubeka "i-avu" yakho.
Uma kuzinhlelo zakho ukubekwa kwezithombe kwi-intanethi, khona-ke ubukhulu nevolumu kuyadingeka ukuba kuncishiswe ubukhulu obamukelekayo. Yebo lapho isikrini sakho sivulwa, akufanele 'siphume' kwewindi lesiphequluli. Inani elivumelekile lezithombe ezinjalo liphathelene namakhulu angama-kilobytes amaningi.
Ukuze unciphise isithombe se-avatars nezibalo ku-albhamu, kuzodingeka wenze izinqubo ezihlukile ngokuphelele.
Uma unciphisa isithombe sama-avatars, khona-ke udinga ukusika kuphela i-fragment encane. Isithombe, njengombuso, asikahleki, sigcinwa ngokuphelele, kodwa ngesikhathi esifanayo inani lilinganiselwa. Uma udinga usayizi wesithombe, kodwa unzima kakhulu, khona-ke ungayinciphisa ikhwalithi yayo. Ngalokho, kuzothatha inkumbulo encane ukusindisa ngayinye yamaphikseli.
Uma usebenzisa i-algorithm yokucindezela efanele, isithombe sokuqala nesithombe esithathwe kuzoba cishe okufanayo.
Ukusika indawo edingekayo ku-Adobe Photoshop
Ngaphambi kokuthi unciphise ubukhulu besithombe ku-Photoshop, udinga ukuyivula. Ukuze wenze lokhu, sebenzisa imenyu yohlelo: "Ifayela - Vula". Okulandelayo, ucacise indawo yesithombe kwikhompyutha yakho.
Ngemuva kokuthi isithombe siboniswe ohlelweni, udinga ukuyibuka ngokucophelela. Cabanga ngezinto zonke ezisesithombeni, udinga. Uma kuphela ingxenye ethile edingekayo, izokusiza. "Uhlaka".
Sika into ngezindlela ezimbili. Okokuqala - kubha yamathuluzi, khetha isithonjana esifisekayo. Kuyinto ibha yokuma lapho kukhona khona izithombe. Itholakala ngakwesokunxele kwefasitela.
Ngayo ungakhetha indawo engxenyeni esithombeni sakho. Udinga kuphela ukuthola ukuthi iyiphi indawo futhi ucindezela ukhiye Ngena. Okusala ngaphandle kwekontane kunqanyuliwe.
Inketho yesibili ukusebenzisa ithuluzi. "Indawo eyingqayizivele". Lesi sithonjana sitholakala kubha yamathuluzi. Ukukhetha isifunda nalesi thuluzi kufana nalokho "Uhlaka".
Emva kokukhetha indawo, sebenzisa into yemenyu: "Isithombe - isitshalo".
Nciphisa isithombe usebenzisa umsebenzi "Usayizi we-Canvas"
Uma udinga ukutshala isithombe kusikhulu esithile, nokususwa kwezingxenye ezidlulele, khona-ke into yemenyu izokusiza: "Usayizi Wevas". Leli thuluzi liyadingeka uma udinga ukususa into eyengeziwe emaphethelweni wesithombe. Leli thuluzi lisemenyu: "Isithombe - Usayizi we-Canvas".
"Usayizi Wevas" Kuwindiza ebonisa imingcele yangempela yesithombe nalabo okuyoba khona emva kokuhlela. Udinga kuphela ukucacisa ukuthi yiziphi ubukhulu obudinga, futhi ucacise ukuthi yiliphi uhlangothi oludinga ukusika isithombe.
Ungacacisa usayizi kunoma yiliphi i-unit elula yesilinganiso (amasentimitha, amamitha, amaphikseli, njll).
Uhlangothi ofuna ukuqala ukuqoqa lungacaciswa ngokusebenzisa insimu lapho imicibisholo ikhona khona. Emva kwayo yonke imingcele edingekayo isethwe ngokuchofoza "Kulungile" futhi uhlela isithombe sakho.
Kunciphisa isifinyezo usebenzisa isici sesayizi yesithombe
Ngemuva kokuthi isithombe sakho sithatha ifomu elifunayo, ungaqala ngokuphepha ukushintsha usayizi walo. Ukuze wenze lokhu, sebenzisa into yemenyu: "Isithombe - Usayizi Wesithombe".
Kule menyu ungalungisa usayizi wesithombe sakho, shintsha inani lazo ku-unit of measure oyidingayo. Uma ushintsha inani elilodwa, zonke ezinye zizoshintsha ngokuzenzakalelayo.
Ngakho, ubukhulu besithombe sakho bugcinwa. Uma udinga ukuphazamisa ubukhulu besithombe, bese usebenzisa isithonjana phakathi kobubanzi nokuphakama.
Ungashintsha nosayizi we-snapshot uma unciphisa noma ukwandisa isinqumo (sebenzisa into yemenyu "Isinqumo"). Khumbula, okuncane ukulungiswa kwesithombe, ukunciphisa ikhwalithi yayo, kepha kufinyelela isisindo esincane.
Londoloza futhi ukwandise isithombe ku-Adobe Photoshop
Ngemva kokufaka zonke izilinganiso nobukhulu obudingayo, udinga ukulondoloza isithombe. Ngaphezu kwalokho, ithimba "Londoloza" ungasebenzisa ithuluzi lohlelo "Londoloza iwebhu"itholakala entweni yemenyu "Ifayela".
Ingxenye enkulu yefasitela yisithombe. Lapha ungayibona ngendlela efanayo lapho izoboniswa khona kwi-Intanethi.
Ngakwesokudla kwefasitela, ungasetha imingcele njengokuthi: ifomethi yesithombe nekhwalithi yayo. Ukuphakama kwezinga, ngcono ikhwalithi yesithombe. Futhi, ungangcolisa kakhulu ikhwalithi usebenzisa uhlu lokudonsa phansi.
Khetha noma iyiphi inzuzo evumelana nawe (Ephansi, Ephakathi, Ephezulu, Ehamba phambili) futhi uhlole ikhwalithi. Uma udinga ukulungisa izinto ezincane ngesayizi, sebenzisa Ikhwalithi. Ngezansi kwekhasi ungabona ukuthi isithombe sakho sinzima kangakanani kulesi sigaba sokuhlela.
Ukusebenzisa "Usayizi izithombe " setha izinketho ezifanele zokulondoloza izithombe.
Ukusebenzisa wonke amathuluzi angenhla, ungadala ukudubula okuphelele ngesisindo esincane.
