PNG iboneye ni iki?
PNG iboneye ni dosiye yishusho aho ibice bimwe bigamije kwerekana ** ntakintu kiri inyuma yingingo **, ibyo aribyo byose rero ushyize dosiye hejuru irashobora kwerekana. Ibyo “ntacyo” ntabwo ari irangi ryera kandi ntabwo ari ibara ryerekana imvi. Namakuru yimikorere, mubisanzwe asobanurwa nka ** alpha **.
Niba ukorana nibicuruzwa, avatar, stikeri, slide, cyangwa ibintu byihuse, ibi bifite akamaro kuruta uko byumvikana. Abantu benshi baravuga ngo “Nkeneye inyuma yakuweho,” ariko icyo bakeneye rwose ni dosiye ishobora kwicara neza hejuru yundi miterere idakwega inyuma.
Igitekerezo cyoroshye
Tekereza ifoto isanzwe nkurukiramende rwuzuye pigiseli. Igice cyose cyurukiramende gifite ibara rigaragara. PNG iboneye ihindura iryo tegeko:
- ingingo ikomeza pigiseli igaragara
- yakuweho inyuma ihinduka ahantu hagaragara
- indi nyandiko, ibara, cyangwa ishusho irashobora kugaragara inyuma yayo nyuma
Niyo mpamvu PNGs iboneye isanzwe kubintu byihariye hamwe nabantu. Baguha guhinduka nyuma yo kohereza hanze.
Impamvu igenzura ryibanze rihari
Niba gukorera mu mucyo ari “ubusa,” ni gute software ishobora kubyerekana?
Abanditsi benshi nababareba bakoresha igenzura ryerekana uturere tubonerana. Igenzura ni ** ntabwo riri muri dosiye **. Nibisanzwe gusa kugirango ijisho ryawe rishobore kumenya aho alfa ihari.
Nibimwe mubisanzwe bitangira kwitiranya:
- “Nohereje dosiye none ndabona kare”
- “Gukuraho inyuma byongeyeho imvi”
Mubisanzwe kwaduka nuburyo bwo kureba gusa bwo kwerekana umucyo. Idosiye ubwayo ikora ikintu cyiza.
Transparent PNG vs inyuma yera
Ibisubizo byombi bikunze kuvangwa, ariko biratandukanye.
PNG iboneye
- inyuma yakuwe kuri alfa
- ikora neza mugihe ushobora gushyira ingingo kumurongo myinshi itandukanye nyuma
- ibyiza byo guhimba, imiterere, no kongera gukoresha
Ibara ryera
- inyuma iracyahari, gusa cyera
- irashobora kuba ingirakamaro kumasoko, doc, cyangwa ibicuruzwa byoherezwa hanze
- guhinduka byoroshye niba nyuma ushaka ingingo hejuru yamabara, icyiciro, cyangwa indi shusho
Nta n’umwe “ufite ubuhanga” muri buri kintu. Bakemura ibibazo bitandukanye. Ikibazo gitangira iyo umuntu yiteze umwe hanyuma kubwimpanuka yohereza undi.
Impamvu PNG ifite akamaro muriki gikorwa
PNG nigisubizo gifatika kuko gishyigikiwe cyane kandi cyunvikana cyane kubisohoka mu mucyo. Urashobora gufungura JPG, WebP, AVIF, cyangwa HEIC ishusho nkiyinjiza, ukuraho inyuma, kandi wohereze ibicuruzwa nka PNG.
Ibyo bivuze ko ikibazo cyakazi atari:
“Ese dosiye y’umwimerere yari imaze gukorera mu mucyo?”
Ni:
Ati: “Nshobora gutandukanya ingingo kandi nkabika ibisubizo muburyo bukomeza gukorera mu mucyo?”
Kuri Easy Background Remover, igisubizo cyanyuma ni PNG.
Icyo alfa isobanura idafite jargon yajugunywe
Alpha nigice cyamakuru yishusho asobanura uburyo pigiseli igomba kugaragara.
- pigiseli igaragara rwose: ingingo irerekana rwose
- pigiseli iboneye rwose: ntakintu kiva kuri iyo pigiseli gisigaye
- gukorera mu mucyo igice: inzibacyuho yoroshye cyangwa igice-kibonerana kirashobora kubaho
Ntugomba kuba injeniyeri yubushakashatsi kugirango ukoreshe iki gitekerezo. Mubuzima busanzwe, irasobanura gusa impamvu impande zoroshye zishobora kugaragara nkibisanzwe iyo kugabanuka ari byiza, nimpamvu ibyoherezwa mu mahanga bisa nabi mugihe umucyo wabuze cyangwa inkombe itatunganijwe.
Aho PNG iboneye ifite akamaro
PNGs isobanutse ningirakamaro cyane mugihe ingingo imwe ishobora gukenera kwimuka hagati:
- urutonde rwibicuruzwa namakarita ya promo
- amashusho yumwirondoro nimpapuro zitsinda
- urupapuro rwerekana amashusho
- ibirango, udupapuro, hamwe nibisanzwe byanditse
- kurenga kuri thumbnail cyangwa mockups
Ubujurire ntabwo ari “PNG ni nziza.” Kujurira ni uko ingingo ikomeza gukoreshwa.
Niki PNG iboneye idakemura wenyine
PNG iboneye ntabwo ari gihamya yerekana ibisubizo bisukuye.
Urashobora kugira:
- impande zose
- asigaye halos kuva kera
- kubura imisatsi
- gabanya inguni ku ngingo zinyuranye
Gukorera mu mucyo birinda guca. Ntabwo isana intege nke zonyine.
Niyo mpamvu impande zombi zigenzura. Imiterere ya dosiye nuburyo bwiza bwo gukorera hamwe, ariko ntabwo arikintu kimwe.
Urugero rufatika
Tekereza igikoma gifotowe cyera. Niba ukuyeho inyuma hanyuma wohereze nka PNG iboneye, urashobora gushira icyo mug mug kuri:
- ibendera ry’amabara
- intambwe yintwari yo guhagarika
- isoko y’isoko
- urupapuro rwo kwerekana
Niba wohereza hanze hamwe numweru yera aho, mug irashobora gukomeza gukoreshwa, ariko urukiramende rwera cyangwa isahani igarukira aho isa nibisanzwe. Verisiyo iboneye iguha byinshi byo gukoresha.
Amakosa asanzwe
Ikosa 1: ukeka ko inyuma yumweru bisobanura gukorera mu mucyo
Ntabwo aribyo. Umweru uracyari amakuru yamakuru. Gukorera mu mucyo ni ukubura amakuru agaragara inyuma.
Ikosa 2: utekereza ko ikibaho kiri muri dosiye yoherejwe hanze
Mubisanzwe ni amasezerano yo kureba gusa. Reba dosiye muburyo butandukanye mbere yo guhitamo ikintu kibi.
Ikosa 3: kohereza muburyo buta alfa
Niba ukeneye gukorera mu mucyo, ibyawe byanyuma bigomba kubikwa. Muri uku gukora, bivuze PNG.
Amakosa 4: gushinja PNG kumpande mbi
Niba impande zisa nkizikennye, ikibazo akenshi ni ubwiza bwa mask cyangwa kubura kunonosorwa, ntabwo kuba dosiye ari PNG.
Imeza yihuse
| Ukeneye | Igisubizo cyiza |
|---|---|
| Ongera ukoreshe ingingo nyinshi | PNG isobanutse |
| Komeza ibintu bisobanutse neza | Umweru cyangwa amabara inyuma |
| Sobanurira mugenzi wawe icyo “nta background” bisobanura | “PNG ibonerana hamwe na alfa” |
| Kugenzura niba gukata kwarakoze rwose | Kugenzura Ikibaho cyambere + kugenzura |
Kwiyoroshya-Icyongereza
PNG ibonerana nuburyo bufatika bwo gukomeza ingingo mugihe ukuraho inyuma yibiboneka, urashobora rero gushyira iyo ngingo neza ahandi hantu nyuma.
Icyo ni igitekerezo cyose. Jargon irahitamo.
