Ijelo leAlpha licaciswe ngesiNgesi esicacileyo
Itshaneli yealpha yinxalenye yomfanekiso ogcina indlela ebonakala ngayo ipixel nganye. Imijelo yombala ichaza obomvu, oluhlaza, nobhlowu. I-Alpha ichaza ukukhanya.
Ukuba ususa imvelaphi kwaye uthumele iPNG ecacileyo, awucimi nje umbala. Ubhala amaxabiso ealpha athi: gcina le pixel, fiphalisa lo mngcipheko, okanye wenze le ndawo ingabonakali ngokupheleleyo.
Yiyo loo nto ii-cutouts ezicacileyo zinokujongeka ngokwendalo xa imiphetho ethambileyo iphathwa kakuhle-kwaye kutheni ukuthunyelwa ngaphandle okubi kukhangeleka kungalunganga nokuba umxholo ubukhali.
Imodeli elula
Kwipixel nganye, ialpha iphendula umbuzo omnye:
- i-opaque ngokupheleleyo: umxholo ubonisa ngokupheleleyo -ngokucacileyo ngokupheleleyo: akukho nto ishiyekayo kule pixel -ngokungafihliyo ngokuyinxenye: ipixel idityaniswa nayo nantoni na ehleli emva kwayo
Ukungafihli kancinci sisizathu esibambekayo sokuba iinwele, uboya, kunye neekhonto ezithambileyo zinokujongeka zikholeleka endaweni yokusikwa ngesikere.
Kutheni le nto ibalulekile ekususweni ngasemva
Ukususa imvelaphi ayikokuphela nje “cima imvelaphi.” Isiphumo esihle sifuna kwakhona umda oziphatha ngokuchanekileyo xa umfanekiso ubekwe kwenye indawo.
UAlpha nguye owenza ezi ziphumo zibekho:
-isihloko sidada phezu kombala omtsha
- imiphetho ethambileyo idibanisa endaweni yokujonga isitampu -I-checkerboard previews ingabonisa imimandla engenanto
Ngaphandle kwealpha, “imvelaphi esusiweyo” ihlala iba yipleyiti emhlophe okanye enye into eqinileyo.
Imiphetho ethambileyo vs imiphetho enzima
Imiphetho enzima ubukhulu becala zizigqibo ezingacacanga-okanye ezingafihliyo. Imiphetho ethambileyo isebenzisa umxube.
Lo mxube uluncedo:
- iintambo zeenwele
- uboya
- iiplastiki zesemi-transparent
- Iikhontolo ezishukumayo
Kukwalapho kuvela khona ingxaki. Ukuba ialpha ikhawuleza kakhulu, umxholo ujongeka usikiwe. Ukuba i-alpha ingcolile, ufumana i-fringe kunye ne-halo.
Yintoni i-alpha engeyiyo
I-Alpha ayikho:
- imvelaphi emhlophe
- ipateni ye-checkerboard ngokwayo
- isiqinisekiso somgangatho ogqibeleleyo womphetho
I-Checkerboard yindibano yokujonga kuqala. Umhlophe usengumbala. I-Alpha yidatha yokubonakala.
Umzekelo osebenzayo
Yiba nomfanekiso wokunqunyulwa kwemveliso kubekwe kwibhena emnyama:
-ialpha elungileyo: umxholo uhleli ngokucocekileyo kungekho rim iluthuthu -i-alpha ebuthathaka: i-fringe emhlophe okanye enemibala ihlala ijikeleze i-contour
Umphetho uhlala ushiyeka kwindlela yokuziphatha, hayi “i-PNG bug” engaqondakaliyo.
Oku kudityaniswa njani kwi Easy Background Remover
Kulolu hlelo lokusebenza:
- Vula umfanekiso womthombo oxhaswayo
- Susa imvelaphi kwindawo
- Cokisa imiphetho ukuba kuyimfuneko
- Thumela i-PNG ukuze ukungafihli (alpha) kugcinwe
Awudingi ukulawula amajelo ealpha ngesandla njengakwisuite yemizobo epheleleyo. Kuya kufuneka uqonde ukuba kutheni ifomati yokuthumela ngaphandle kunye nomcimbi wokucoca umda.
Iimpazamo eziqhelekileyo
Impazamo 1: ukuphatha ialpha njengejagoni ozikhethelayo
Ukuba ufuna ukuphinda usetyenziswe kwindawo yangasemva, ialpha yeyona ngongoma.
Impazamo 2: ukubhidanisa isiphelo esithambileyo kunye nentsalela yasemva eshiyekileyo
Ukuthamba okuthile kulungile. Umbala ongemva omdala obonakalayo awukho.
Impazamo yesi-3: gcina kwakhona kwifomathi eyehlisa ukungafihli
Ukuba i-alpha ilahlekile, i-cutout iyayeka ukuba bhetyebhetye.
Impazamo yesi-4: ukugxeka ingqikelelo endaweni yomphetho
Ifayile ecacileyo isengakhangeleka imbi ukuba imaski irhabaxa.
Itafile ekhawulezayo
| Ixesha | Intsingiselo ecacileyo |
|---|---|
| Alpha | Ibonakala njani ipixel |
| I-PNG eNgaphandle | Umfanekiso onokugcina iindawo ezingenanto nge alpha |
| Ungqameko oluthambileyo | Inxalenye yealfa ejikeleze umda |
| Halo / umphetho | Umbala womphetho ongafunekiyo osinda ekusikeni |
