Yintoni iPNG esobala?
I-PNG ecacileyo yifayile yomfanekiso apho amanye amalungu enzelwe ukubonisa akukho nto emva kwesihloko, ngoko ke nantoni na obeka ifayile phezu kwayo ingabonisa. Ukuba “akukho nto” ayikho ipeyinti emhlophe kwaye ayikho ipateni yokujonga igrey. Yidatha engafihliyo, edla ngokuchazwa njenge-alpha.
Ukuba usebenza ngokusikwa kweemveliso, ii-avatar, izitikha, izilayidi, okanye imidibaniso ekhawulezayo, oku kubaluleke ngakumbi kunokuba kuvakala. Abantu abaninzi bathi “Ndifuna imvelaphi isuswe,” kodwa eyona nto bayifunayo yifayile enokuhlala icocekile ngaphezulu kolunye uyilo ngaphandle kokutsala imvelaphi yakudala.
Ingcamango elula
Cinga ngefoto eqhelekileyo njengoxande oluzele ngeepikseli. Inxalenye nganye yoluxande inombala obonakalayo. I-PNG ecacileyo iyawutshintsha lo mgaqo:
- Umbandela ugcina iipixels ezibonakalayo
- i-backdrop esusiweyo iba yindawo ecacileyo -olunye uxwebhu, umbala, okanye umfanekiso unokuvela emva kwayo kamva
Yingakho ii-PNG ezicacileyo zixhaphake kakhulu kwizinto ezizimeleyo kunye nabantu. Bakunika ukuguquguquka emva kokuthumela ngaphandle.
Kutheni ibhodi yokujonga ipreview ikhona
Ukuba ukungafihli “akukho nto,” ingayibonisa njani isoftware?
Uninzi lwabahleli kunye nababukeli basebenzisa ipateni yebhodi yokukhangela ukumela imimandla engafihliyo. Ibhodi yokukhangela ayiyonxalenye yefayile **. Yindibano nje yokujonga kuqala ukuze iliso lakho likwazi ukubona ukuba ialpha ikhona phi.
Le yenye yezona ziphazamiso zixhaphakileyo zabaqalayo:
“Ndithumele ngaphandle ifayile kwaye ngoku ndibona izikwere”
- “Isisusa sangasemva songeze ipateni engwevu”
Ngokuqhelekileyo izikwere kuphela yindlela yombukeli yokubonisa ukungafihli. Ifayile ngokwayo yenza into elungileyo.
I-PNG ecacileyo vs imvelaphi emhlophe
Ezi ziphumo zibini zihlala zixubene, kodwa zahlukile.
Transparent PNG
- imvelaphi isusiwe kwi alpha
- isebenza kakuhle xa unokubeka isifundo kwiimvelaphi ezininzi ezahlukeneyo kamva -Eyona nto ingcono yokuqamba, uyilo, kunye nokusetyenziswa kwakhona okubhetyebhetye
Imvelaphi emhlophe
- imvelaphi isekhona, imhlophe nje -inokuba luncedo kwiimarike, amaxwebhu, okanye ukuthumela ngaphandle ngokulula -Inokuguquka kancinci ukuba kamva ufuna isihloko phezu kombala, igradient, okanye omnye umfanekiso
Akukho namnye “onobuchule ngakumbi” kuyo yonke imeko. Basombulula iingxaki ezahlukeneyo. Ingxaki iqala xa umntu elindele enye kwaye ngempazamo athumele enye.
Kutheni i-PNG ibalulekile kolu hambo lomsebenzi
I-PNG yimpendulo esebenzayo kuba ixhaswa ngokubanzi kwaye iqondwa ngokubanzi kwimveliso ecacileyo. Unako ukuvula iJPG, WebP, AVIF, okanye HEIC umfanekiso njengegalelo, susa imvelaphi, kwaye uthumele i-cutout njengePNG.
Oko kuthetha ukuba umbuzo wokuhamba komsebenzi awukho:
“Ngaba ifayile yokuqala yayisele ihleli ekuhleni?”
Yiyo:
“Ngaba ndingawubeka bucala umxholo kwaye ndigcine isiphumo kwifomati egcina ukungafihli?”
Ku-Easy Background Remover, loo mpendulo yokugqibela yi-PNG.
Lithetha ukuthini ialpha ngaphandle kokulahlwa kwejagoni
I-Alpha yinxalenye yedatha yomfanekiso echaza ukuba i-pixel kufuneka ibonakale njani.
-i-pixel ebonakalayo ngokupheleleyo: umxholo ubonisa ngokupheleleyo -i-pixel ecace ngokupheleleyo: akukho nto ishiyekayo kule pixel
- ukungafihli ngokuyinxenye: iinguqu ezithambileyo okanye ezingafihliyo zingabakho
Awudingi ukuba yinjineli yegraphics ukusebenzisa le ngcamango. Kubomi bokwenyani, icacisa ngokulula ukuba kutheni imiphetho ethambileyo inokujongeka yendalo xa i-cutout ilungile, kwaye kutheni ukuthunyelwa ngaphandle ngokurhabaxa kujongeka kubi xa ukukhanya bekulahlekile okanye umphetho ungalungiswanga.
Apho iiPNG ezicacileyo ziluncedo
Ii-PNG ezicacileyo ziluncedo ngakumbi xa umxholo omnye unokufuna ukuhamba phakathi kwemixholo:
- uluhlu lweemveliso kunye namakhadi okuthengisa
- imifanekiso yeprofayile kunye namaphepha eqela -idekhi zesilayidi kunye namaxwebhu
- iilebhile, izincamathelisi, kunye nolungiselelo olulula lokuprinta
- Ukwaleka kwe thumbnails okanye mockups
Isibheno ayisi “PNG imnandi.” Isibheno kukuba umxholo uhlala usetyenziswa kwakhona.
Yintoni iPNG ecacileyo ayizisombululi ngokwayo
I-PNG ecacileyo ayikho ubungqina obuzenzekelayo besiphumo esicocekileyo.
Usenako:
- imiphetho erhabaxa -i-halos ezishiyekileyo ezivela kwimvelaphi yakudala
- iintambo zeenwele ezilahlekileyo
- ukusika iikona kwizifundo ezinomchako ophantsi
Ukungafihlisi kugcina ukusika. Ayilungisi i-cutout ebuthathaka ngokwayo.
Kungenxa yoko le nto ukuhlolwa komda kubalulekile. Ifomathi yefayile kunye nomgangatho wokusika zisebenza kunye, kodwa aziyonto enye.
Umzekelo osebenzayo
Yiba nomfanekiso wemagi efotwe kumhlophe. Ukuba ususa imvelaphi kwaye uthumele ngaphandle njengePNG ecacileyo, ungabeka kamva imagi kwi:
- ibhanile enemibala -ibhloko yeqhawe legradient
- ithayile yemarike
- isilayidi somboniso
Ukuba uthumela ngaphandle ngemvelaphi emhlophe endaweni yoko, imagi isenokusebenziseka, kodwa uxande olumhlophe okanye ipleyiti imida apho ikhangeleka ngokwendalo. Inguqulelo ecacileyo ikunika ukusetyenziswa kwakhona okungakumbi.
Iimpazamo eziqhelekileyo
Impazamo 1: ukuthatha ibackdrop emhlophe ithetha ukungafihli
Akunjalo. Imhlophe iselulwazi lombala. Ukungafihli kukungabikho kwedatha yasemva ebonakalayo.
Impazamo yesi-2: ukucinga ukuba ibhodi yokukhangela yinxalenye yefayile ethunyelwa ngaphandle
Ngokwesiqhelo yindibano yokujonga kuqala. Jonga ifayile kumxholo owahlukileyo ngaphambi kokuba wenze isigqibo sokuba kukho into engalunganga.
Impazamo yesi-3: ukuthumela ngaphandle kwifomati ewisa ialpha
Ukuba ufuna ukungafihli, ukuhanjiswa kwakho kokugqibela kufuneka kugcinwe. Kolu hambo lomsebenzi, oko kuthetha ukuba iPNG.
Impazamo yesi-4: ukugxeka i-PNG ngemiphetho embi
Ukuba umphetho ubonakala uhlwempuzekile, umba uhlala ubulunga okanye ukungabikho kokucokisa, hayi into yokuba ifayile yiPNG.
Itafile ekhawulezayo
| Kufuneka | Isiphumo esingcono |
|---|---|
| Sebenzisa kwakhona umxholo kwiimvelaphi ezininzi | I-PNG eNgaphandle |
| Gcina imvelaphi engaguqukiyo ethafeni | Imvelaphi emhlophe okanye enemibala |
| Chazela umdlali weqela ukuba kuthetha ukuthini “ukungabinamva” | “I-PNG ecacileyo nge-alpha” |
| Jonga ukuba ingaba isisikwa sisebenze ngenene | I-Checkerboard preview + edge check |
I-takeaway yesiNgesi esicacileyo
I-PNG ecacileyo yindlela nje esebenzayo yokugcina isihloko ngelixa ususa umva obonakalayo, ukuze usibeke isifundo ngokucocekileyo kwenye indawo kamva.
Leyo yingcamango epheleleyo. Ijagoni ayinyanzelekanga.
