Imida yangasemva yeJPG: yintoni ifomathi engenakuyigcina
IJPG ayinakugcina imvelaphi engafihliyo. Yonke ipixel kwiJPG kufuneka isombulule kumbala obonakalayo, ke ukusika okugcinwe njengeJPG kuthotywe kumhlophe, kumnyama, okanye omnye umbala okhethiweyo. Ukuba ufuna indawo ejikeleze umxholo ukuze uhlale ungenanto, thumela ngaphandle i-PNG endaweni yoko.
Lo mda ayenzi iJPG ifoto yemvelaphi embi. Kuthetha kuphela ukuba iJPG kunye nemveliso ebonakalayo inemisebenzi eyahlukeneyo.
Kuthetha ukuthini “ukungena elubala”
I-cutout iqulethe iindidi ezimbini zolwazi:
- umbala obonakalayo wesifundo;
- ukuba ipikseli nganye kufuneka ibonakale njani, kubandakanywa iipikseli zomphetho ezingenanto ngokupheleleyo kwaye ngokuyinxenye.
Icandelo lesibini lidla ngokubizwa ngokuba yialpha. IJPG ayinandawo yokuyigcina.
Xa isoftware ijika ukusika ekuhleni kwiJPG, kufuneka igqibe ukuba ngowuphi umbala obonakalayo othatha indawo yawo yonke ipixel engenanto. Isiphumo siba luxande olupheleleyo kwakhona. Rhoqo olo tshintsho lumhlophe, kodwa lunokuba mnyama okanye nakuphi na ukugcwaliswa okukhethiweyo.
Akukho nto iphosakeleyo ngefayile. Ulwazi olungafihliyo lususiwe kuba ifomathi yendawo ayikwazanga ukuyithwala.

JPG isengaba ligalelo
Uninzi lweefoto zekhamera kunye nefowuni ziyimifanekiso eqhelekileyo yoxande. Bafika benegumbi, udonga, isitrato, okanye itafile esele ibonakala emva kwesifundo. Loo nto yenza iJPG igalelo eliqhelekileyo lokususa ngasemva.
Inkqubo eluncedo yile:
- vula umthombo weJPG;
- wubeke bucala umbandela;
- hlola kwaye usulungekise umda;
- thumela ngaphandle isiphumo esitsha njengePNG.
Umthombo kunye nemveliso ayifuni ukusebenzisa ifomathi efanayo. Guqula ifoto yeJPG ibe yiPNG ekhanyelayo ihamba kulo msebenzi ngokuthe ngqo.
Kutheni imvelaphi emhlophe inokulahlekisa
Ukusika kumhlophe kunokujongeka ngaphaya xa kujongwe kwiphepha elimhlophe. Yishenxise kwisilayidi esimnyama kwaye ipleyiti emhlophe exande iyabonakala.
Sebenzisa olu vavanyo lukhawulezayo:
- beka umfanekiso phezu kombala oqaqambileyo ongenamhlophe; 2 jonga kuzo zone iimbombo;
- khangela izithuba ezingalweni, izibambo, neenwele.
Ukuba umbala wokuvavanya awubonakali kwezo ndawo, ifayile ifakwe. Igama lefayile elithi .jpg liyaqinisekisa ukuba kutheni. Igama lefayile .png linokuxhasa ukungafihli, nangona i-PNG isenokuba ithunyelwe ngaphandle ngenjongo ngokuzaliswa okusisigxina.
Umhlophe ngumbala. Ukungafihli kukungabikho kweepixels zangasemva ezibonakalayo.
Imiphetho ethambileyo iveza omnye umda
Ukusika okulungileyo akuhlali kunomda onzima. Iinwele, uboya, ilaphu, izithunzi, kunye ne-anti-aliased curves zinokuqulatha iipikseli zomphetho ezingacacanga. UAlpha uvumela ezo pixels zidityaniswe nemvelaphi entsha.
Xa i-edge ebonisa izinto ezicacileyo igudiswe kwiJPG, i-edge idityaniswa kumbala omnye osisigxina. Beka loo JPG kumbala owahlukileyo kwaye unokubona:
- umfanekiso ocacileyo;
- umphetho omnyama;
- iikona zebhokisi ezijikeleze iinkcukacha ezintle;
- i-matte ekhohlo kwi-original fill.
Yiyo loo nto ukususa ngokulula uxande olumhlophe kwiJPG kamva akusoloko kuphinda kufumaneke i-cutout yokuqala. Iiphikseli zenguqu sele zixutywe nomhlophe.
Ukugcinwa kweJPG okuphindaphindiweyo kunokunciphisa umgangatho
IJPG isebenzisa ucinezelo olulahlekileyo. Yenzelwe ukwenza imifanekiso yemifanekiso ibe mincinci ngokwenza lula iinkcukacha ezibonwayo. Ugcino ngalunye olongezelelweyo lunokwazisa ngakumbi ukukhala, ukuvaleka, okanye ukuthambisa, ngakumbi kwincam ezibukhali ezinomchako ophezulu.
Ezo zixhobo zibalulekile kumda wokusika kuba umphetho kanye apho kufuneka iinkcukacha ezicocekileyo. Umthombo oxinaniswe kakhulu unokubonisa:
- iicontours ezingacacanga;
- iibhloko zemibala emincinci kufutshane nolwandlalo;
- iintambo ezilahlekileyo okanye iindawo ezincinci;
- Ingxolo yombala efana neenkcukacha ngasemva.
Ukuthumela ngaphandle kwi-PNG kuthintela elinye inqanaba leJPG elilahlekileyo emva kokunqunyulwa. Ayinakubuyisela inkcukacha esele ilahlekile kumthombo, kodwa iyakunqanda ukongeza ucinezelo lweJPG kwisiphumo esicacileyo.
Xa iJPG iseyifayile yokugqibela echanekileyo
IJPG inokuba yifomathi yonikezelo enengqiqo xa zonke ezi ziyinyani:
- imvelaphi yokugqibela ilungiswe ngabom;
- ukungafihli akufuneki;
- umfanekiso ubukhulu becala; -indawo yokufikela iyayamkela okanye ikhetha iJPG; -Ubungakanani obuncinci bokuhanjiswa bubaluleke ngaphezu kotshintsho lwangasemva kwixesha elizayo.
Umzekelo, isibhengezo esigqityiweyo esinomva opheleleyo wemifanekiso sinokungaxhamli kwialpha. Ifoto yekhathalogu esemva emhlophe egqityiweyo isenokuthi ihanjiswe njengeJPG ukuba iinkcukacha zokufumana ziyayifuna.
Ingongoma ebalulekileyo yinjongo. Gcoba inkosi ecacileyo kumbala ofunekayo, emva koko wenze ikopi yokuhanjiswa kweJPG. Musa ukulahla inkosi ngaphandle kokuba uqinisekile ukuba isifundo asisayi kufuna enye imvelaphi.

Iimpazamo eziqhelekileyo zokubuyisela
Ukunika igama ngokutsha ulwandiso
Ukutshintsha image.jpg ukuya image.png ayiguquli ifayile okanye ibuyisele ialpha. Thumela ngaphandle okanye uguqule ngesoftware ebhala ngokwenene idatha yePNG.
Kucinywa mhlophe kwiJPG ecaba
Oku kunokusebenzela imizobo elula ebukhali, kodwa ihlala yonakalisa iindawo ezimhlophe zesifundo kwaye ishiya ungcoliseko oluluthuthu. Ukubuyela kumphathi ocacileyo kukhuselekile.
Ithumela imboniso endaweni yokuthumela ngaphandle
Umfanekiso wekhusi uthoba imboniso yonke, kuquka nayiphi na ibhodi yokukhangela ebonakalayo. Sebenzisa isenzo sokuthumela ngaphandle somhleli.
Kucingelwa ukuba yonke iPNG iselubala
I-PNG inokuthwala ialpha, kodwa inokuqulatha imvelaphi epaque ngokupheleleyo. Yiqinisekise ngombala owahlukileyo.
Eyona ndlela ikhuselekileyo yokusebenza
Sebenzisa iJPG kwinto eyenzayo kakuhle: igalelo leefoto eziqhelekileyo kunye nokuhanjiswa okungasemva okusisigxina. Sebenzisa i-PNG xa isiphumo kufuneka sigcine ukungafihli.
Gcina i-PNG master ecocekileyo emva kokususwa ngasemva. Ukusuka kuloo nkosi, yenza iJPG emhlophe, iJPG enemibala, okanye enye indawo yokukhuphela xa ifuneka. Lo myalelo ugcina iinketho kwaye unqanda ukuzama ukuphinda wenze elubala emva kokuba umcaba.
