Amafomethi ezithombe asekelwayo okususwa kwengemuva

By Technical specialist

Inguqulo emfushane: Easy Background Remover yakhelwe ukuze ivule amafomethi wesithombe avamile njengokufakwayo futhi ikhiphe umphumela njenge-transparent PNG. Lowo mehluko ubalulekile. Abantu bavame ukubuza ukuthi ingabe ithuluzi “liyakusekela ukubonakala kwe-JPG” lapho abakudinga ngempela kungukuthi: ngingakwazi yini ukulayisha leli fayela, nginqume isihloko, bese ngigcina umphumela nge-alpha?

Kulo mkhiqizo, impendulo iyasebenza:

• Okokufaka kungase kuhlanganise PNG, JPG, WebP, AVIF, HEIC, kanye ne-HEIF
• Okukhiphayo kokusikwa kweqiniso ngu-PNG
• Ingemuva elimhlophe noma elinombala elithi akuyona into efanayo nokukhanyela

Ifomethi yokufaka iqhathaniswa nefomethi yokuphumayo

Uma abantu bekhuluma “ngamafomethi asekelwayo,” ngokuvamile baxuba imibuzo emibili ehlukene:

1. Ingabe umhleli angavula ifayela lami lokuqala?
2. Iyiphi ifomethi okufanele ngiyithumele uma ngifuna umphumela osobala?

Lezo akuzona isinqumo esifanayo.

Isithombe se-JPG singaba*ukokufaka** okuhle kakhulu kokususwa kwengemuva. Ngeke nje kube ifomethi yokugcina yokubonisa ngale kwangempela, ngoba i-JPG ayigcini isiteshi se-alpha. Isandiso singavula i-JPG, sisuse okwasemuva, bese sithekelisa umphumela njenge-PNG.

Lo mqondo ofanayo uyasebenza nakwamanye amafomethi. “Ukusekelwa” kufanele kusho “okusebenzisekayo ekuhambeni komsebenzi,” hhayi “zonke izinhlobo zenza wonke umsebenzi ngendlela efanayo.”

Kusho ukuthini amafomethi ajwayelekile ekusebenzeni

PNG

I-PNG ifomethi elula ukuyiqonda kulokhu kuhamba komsebenzi.

• Okokufaka okuhle uma usuvele unesithombe esinamaphethelo aqinile
• Okukhiphayo okuhle kakhulu lapho udinga **ukukhanya kwangempela **
• Inketho evamile ye-handoff yokuklama, amaslayidi, ukufakwa kuhlu, izitika, nezinhlanganisela ezisheshayo

Uma umgomo wakho “uyisihloko esingenasizinda ngemuva kwakho,” i-PNG iwukuthekelisa okufanele unakekelwe.

JPG / JPEG

I-JPG ingenye yezindawo ezivame ukuqala ngoba izithombe eziningi zefoni nezekhamera zifika ngale ndlela.

• Kuhle njengokufakwayo kwezithombe ezijwayelekile
• Ingabe ** ayikuphathi obala njengokukhiphayo
• Imvamisa ezincane zezithombe, kodwa azifanele umphumela wokusika obala

Lena ifomethi engemuva kokungaqondi okuvamile: “Ngisuse ingemuva elimhlophe, kungani kusemhlophe?” Ngokuvamile impendulo iwukuthi othile uthumele noma walondoloza kabusha kufomethi engagcini i-alpha.

I-WebP

I-WebP ivamile kumawebhusayithi futhi ngezinye izikhathi ezimpahleni ezilandiwe.

• Iwusizo njengokufakwayo uma ulondoloza isithombe kuwebhu
• Ingakwazi ukusekela obala njengefomethi ngokuvamile
• Kulo mkhiqizo, indlela ethembekile yokuthekelisa yokusikwa kuseyi-PNG

Akukhona ukuphikisana lokho. Ifomethi ingase isekele ukubonisa ngale emcabangweni kuyilapho ukugeleza komsebenzi okuthile kumiswa ku-PNG ngoba kuyisandla esincane esididayo kubasebenzisi abaningi.

AVIF

I-AVIF ingasebenza kahle futhi yesimanjemanje, kodwa abasebenzisi abaningi bahlangabezana nayo ngenxa nje yokuthi isiphequluli noma isayithi lilethe isithombe ngaleyo fomethi.

• Iwusizo njengokufakwayo lapho isithombe somthombo siyi-AVIF
• Isibonelo esihle sokuthi kungani “kungavula” izindaba ngokwehlukana nokuthi “kufanele kuthekeliswe njenge”
• Uma umgomo wokugcina kuyimpahla esobala, i-PNG ihlala ingumphumela oqondile

HEIC / HEIF

I-HEIC ne-HEIF ivamise ukuvela emafonini.

• Iwusizo njengokufakwayo lapho okwangempela kwakho kuhlala kudivayisi yeselula
• Kuyasebenza ukuletha izithombe zefoni entsha ekuhambeni komsebenzi wokusika
• Umphumela ofanayo wokukhiphayo: umphumela osobala usho ukuthekelisa kwe-PNG

Lawa mafomethi anendaba encane njenge-“SEO buzzwords” nangaphezulu njengezinciphisi zokushayisana. Uma abasebenzisi kungadingeki baguqule isithombe sabo kwenye indawo ngaphambi kokuthi baqale, ukuhamba komsebenzi kubalula kakhulu.

Kungani ukuthekelisa okusobala ngokuvamile kusho i-PNG lapha

Ukubonisa ngale akuwona “ingemuva elimhlophe elibukeka lingenalutho.” Yidatha ethi, empeleni, “ayikho i-pixel lapha.” Yingakho ukuhlola kuqala kwebhodi lokuhlola kukhona: kubonisa lapho i-alpha ikhona.

I-PNG iyimpendulo elula ngoba iqondwa kabanzi futhi yamukelwa kabanzi. Uma othile ephonsa isihloko kusilayidi, ohlwini, noma umfanekiso wokuklama, i-PNG ifomethi abantu abaningi abalindele ukuthi isebenze ngaphandle kwencazelo eyengeziwe.

Ngakho umthetho womkhiqizo ulula ngamabomu:

• Vula amafomethi omthombo avamile
• Susa ingemuva endaweni yangakini kusiphequluli
• Thumela umphumela obala njenge-PNG

Imithetho elula inciphisa imibuzo yokusekela.

Yini ethinta ikhwalithi yokusika ngaphezu kwesandiso sefayela

Abantu kwesinye isikhathi basola ifomethi lapho inkinga yangempela kuyisithombe ngokwaso. Empeleni, ikhwalithi incike kakhulu kulezi zici:

• Ukungafani kwesihloko ngokumelene nengemuva
• Imininingwane emihle enqenqemeni njengezinwele, uboya, izintambo, noma izinto ezibonakalayo
• Ukufiphala kokunyakaza noma umsindo
• Ukuthi uchitha imizuzwana embalwa ucwenga usebe

I-JPG ehlanzekile ingakhiqiza ukusika okungcono kune-PNG engcolile. Isandiso asihluleli isandiso sefayela kuphela; isebenza ngesihloko esibonakalayo nokwasemuva.

Ithebula elingokoqobo lokulindela

Amaphutha ajwayelekile

Iphutha 1: ukuphatha i-JPG sengathi ingagcina obala

Ngeke. I-JPG ivamise ukuba ifayela eliqalayo, hhayi elokugcina elilethekayo elibonisa ngale.

Iphutha 2: ukuthatha ipuleti elimhlophe lilingana nokucaca

Ingemuva elimhlophe lingaba usizo, kodwa kuseyingemuva. Uma udinga isihloko sintanta ngokuhlanzekile kwezinye izakhiwo, thekelisa nge-alpha.

Iphutha lesi-3: ukusola ifomethi esikhundleni sonqenqema

Uma izinwele noma amakhona amancane abukeka kabi, isinyathelo esilandelayo sivame ukucwengwa, hhayi ukushintshwa kwefomethi.

Iphutha lesi-4: silindele ukuthi yonke ifomethi yesimanje ibe ukuthunyelwa okuncanyelwayo

Usekelo lokokufaka kanye nezincomo zokuphumayo kuyizinqumo ezihlukene. Kulokhu kuhamba komsebenzi, i-PNG igcina umlayezo ucacile.

Umthetho olula wesithupha

Uma ukhumbula into eyodwa kuphela, khumbula lokhu:

Letha noma yisiphi isithombe esisekelwayo osuvele unaso. Thekelisa i-PNG uma ufuna ukubonakala kwangempela.

Lowo mthetho uhlanganisa amacala amaningi asebenzayo ngaphandle kwe-jargon.

Ngohlelo lokusebenza olusebenza ngezandla, qhubeka ngokuthi Indlela yokwenza i-PNG ekhanye ngale. Ngohlangothi lwezobuchwepheshe lokucutshungulwa kwendawo, bona Indlela ukususa ingemuva lendawo kusebenza ngayo.
