Gushigikira imiterere yishusho yo gukuraho inyuma

By Technical specialist

Inyandiko ngufi: Easy Background Remover yubatswe kugirango ** fungura imiterere rusange yifoto nkiyinjiza ** hanyuma wohereze ibisubizo nka ** umucyo PNG **. Itandukaniro rifite akamaro. Abantu bakunze kubaza niba igikoresho “gishyigikira JPG transparency” mugihe icyo bakeneye rwose aricyo: nshobora gupakira iyi dosiye, guca ingingo, no kubika ibisubizo hamwe na alfa?

Kuri iki gicuruzwa, igisubizo ni ingirakamaro:

• Iyinjiza irashobora gushiramo ** PNG, JPG, WebP, AVIF, HEIC, na HEIF **
• Ibisohoka kubice byukuri ni ** PNG **
• Inyuma yera cyangwa ibara risanzwe ni ** ntabwo ** ikintu kimwe no gukorera mu mucyo

Imiterere yinjiza vs imiterere yasohotse

Iyo abantu bavuga kubyerekeye “imiterere ishyigikiwe,” mubisanzwe bavanga ibibazo bibiri bitandukanye:

1. ** Umwanditsi arashobora gufungura dosiye yumwimerere? **
2. ** Ni ubuhe bwoko nkwiye kohereza hanze niba nshaka ibisubizo biboneye? **

Ibyo ntabwo ari umwanzuro umwe.

Ifoto ya JPG irashobora kuba nziza ** yinjiza ** yo gukuraho inyuma. Ntibishobora kuba imiterere yanyuma yo gukorera mu mucyo, kuko JPG ntabwo ibika umuyoboro wa alfa. Kwagura birashobora gufungura JPG, gukuramo inyuma, hanyuma kohereza ibisubizo nka PNG.

Iyo logique imwe ikoreshwa no mubindi bisobanuro. “Gushyigikirwa” bigomba gusobanura “gukoreshwa mubikorwa,” ntabwo “imiterere yose ikora akazi kamwe neza.”

Icyo imiterere isanzwe isobanura mubikorwa

PNG

PNG nuburyo bworoshye kubyumva muriki gikorwa.

• Kwinjiza neza mugihe usanzwe ufite igishushanyo gifite impande zikomeye
• Ibisohoka byiza mugihe ukeneye ** transparency nyayo **
• Guhitamo bisanzwe kubishushanyo mbonera, amashusho, urutonde, udupapuro, hamwe nibintu byihuse

Niba intego yawe ari “ingingo idafite amateka inyuma,” PNG nicyohereza hanze kugirango witondere.

JPG / JPEG

JPG nimwe mubintu bisanzwe bitangiriraho kuko amashusho menshi ya terefone na kamera bigera murubu buryo.

• Nibyiza nkinjiza kumafoto asanzwe
• Ntabwo ** idatwara transparency nkibisohoka
• Mubisanzwe bito kumafoto, ariko ntibikwiriye kubisubizo byaciwe

Ubu ni bwo buryo bwihishe inyuma yo kutumvikana cyane: “Nakuyeho ibara ryera, kuki bikiri umweru?” Akenshi igisubizo nuko umuntu yohereje hanze cyangwa yongeye kubikwa kumiterere idakomeza alfa.

Urubuga

WebP isanzwe kurubuga kandi rimwe na rimwe mumitungo yakuweho.

• Nibyiza nkinjiza mugihe ubitse ishusho kurubuga
• Irashobora gushyigikira gukorera mu mucyo nka format muri rusange
• Kuri iki gicuruzwa, inzira yizewe yo kohereza ibicuruzwa iracyari ** PNG **

Ibyo ntabwo bivuguruzanya. Imiterere irashobora gushyigikira gukorera mu mucyo mugihe ibikorwa byihariye bikora kuri PNG kuko aribintu bitesha umutwe abakoresha benshi.

AVIF

AVIF irashobora gukora neza kandi igezweho, ariko abakoresha benshi bahura nayo gusa kuberako mushakisha cyangwa urubuga rwatanze ishusho murubwo buryo.

• Urugero rwiza rwimpamvu “ishobora gufungura” ibintu bitandukanye na “bigomba kohereza hanze”
• Niba intego yanyuma ari umutungo ubonerana, PNG ikomeza gusohoka neza

HEIC / HEIF

HEIC na HEIF akenshi biva kuri terefone.

• Nibyiza nkinjiza mugihe umwimerere wawe ubaho kubikoresho bigendanwa
• Nibyiza byo kuzana amafoto ya terefone mashya mubikorwa byo gukata
• Ibisohoka bimwe logique: ibisubizo biboneye bisobanura PNG yohereza hanze

Iyi format ntacyo itwaye nka “SEO buzzwords” nibindi byinshi bigabanya guterana amagambo. Niba abakoresha batagomba guhindura ifoto yabo ahandi hantu mbere yuko batangira, akazi karakoroha cyane.

Kuki kohereza ibicuruzwa bisobanutse mubisanzwe bisobanura PNG hano

Gukorera mu mucyo ntabwo ari “umweru wera usa n’ubusa.” Ni amakuru avuga, mubyukuri, “hano nta pigiseli ihari.” Niyo mpamvu igenzura ryibanze rihari: berekana aho alfa ihari.

PNG nigisubizo cyoroshye kuko cyunvikana cyane kandi cyemewe cyane. Niba umuntu ataye ingingo mumurongo, kurutonde, cyangwa gushushanya, PNG nuburyo abantu benshi biteze gukora nta bisobanuro byinyongera.

Amategeko y’ibicuruzwa rero aroroshye nkana:

• Fungura imiterere isanzwe
• Kuraho imiterere yimbere muri mushakisha

Amategeko yoroshye agabanya ibibazo byingoboka.

Niki kigira ingaruka kumiterere irenze kwagura dosiye

Abantu rimwe na rimwe bashinja imiterere iyo ikibazo nyacyo ari ishusho ubwayo. Mubikorwa, ubuziranenge buterwa cyane nibi bintu:

• Itandukaniro ryibintu bitandukanye ninyuma
• Ibisobanuro byiza nkumusatsi, ubwoya, insinga, cyangwa ibikoresho bisobanutse
• Icyerekezo kijimye cyangwa urusaku
• Niba ukoresha amasegonda make gutunganya inkombe

JPG isukuye irashobora gutanga umusaruro mwiza kuruta PNG irimo akajagari. Kwagura ntabwo gucira urubanza kwagura dosiye wenyine; ni gukorana nibintu bigaragara hamwe ninyuma.

Ikosa 3: gushinja imiterere aho kuba ku nkombe

Niba umusatsi cyangwa inguni zisa neza, intambwe ikurikira ikunze kunonosorwa, ntabwo ihindura imiterere.

Ikosa rya 4: kwitega imiterere yose igezweho niyo yoherejwe hanze

Inkunga yinjiza nibisohoka ibyifuzo nibyemezo bitandukanye. Kuri uku gukora, PNG ikomeza ubutumwa neza.

Amategeko yoroshye yintoki

Niba wibuka ikintu kimwe gusa, ibuka ibi:

** Zana ifoto iyo ari yo yose ishyigikiwe usanzwe ufite. Kohereza PNG niba ushaka gukorera mu mucyo. **
