Ukuqonda ukungafihli kwiMifanekiso yeDijithali

Yintoni Ukungafihli?

Kwimifanekiso yedijithali, ukucaca kuthetha ukuba ezinye iipixels zinokubonakala ngokuyinxenye okanye ngokupheleleyo. Xa ubeka umfanekiso ocacileyo kwimvelaphi enemibala - iwebhusayithi, uyilo, okanye omnye umfanekiso - iindawo ezicacileyo zibonisa nantoni na esemva kwazo endaweni yombala oqinileyo.

Ukungafihli kubalulekile kwiilogo, ukusika kwemveliso, izinto ezingaphezulu, kunye nayo nayiphi na indibaniselwano apho ufuna umxholo wakho udityaniswe kumxholo omtsha. Ukususwa kwemvelaphi kudala ekuhleni ngokwenza imvelaphi yokuqala ingabonakali.

Umjelo weAlpha

I-RGB vs RGBA

Imifanekiso emininzi isebenzisa i-RGB: ipixel nganye ineRed, Green, kunye neBlue value echaza umbala wayo. Imifanekiso ecacileyo yongeza ixabiso lesine: Alpha. I-RGBA ithetha eBomvu, eluhlaza, eBlue, kunye neAlpha. Ijelo le-alpha limisela ukuba i-pixel nganye ivuleke kangakanani na okanye icace gca.

Iimpawu zeAlpha

I-Alpha igcinwa njengenani ukusuka ku-0 ukuya ku-255 (okanye i-0% ukuya kwi-100%). I-0 = icace ngokupheleleyo (engabonakaliyo). 255 = i-opaque ngokupheleleyo (eqinile). Amaxabiso aphakathi adala ukubonakala kwe semi-transparency - luncedo kumaphethelo athambileyo, izithunzi, kunye neziphumo zeglasi.

Iifomathi ezixhasa ukungafihli

I-PNG

I-PNG ixhasa ialpha epheleleyo (i-8-bit okanye i-16-bit). Yeyona fomati ixhaphakileyo yemifanekiso ebonisa elubala. I-PNG ayilahleki, ngoko ke imiphetho ecacileyo ihlala ilungile. Le yifomati yokuthumela ngaphandle esemgangathweni yokususwa ngasemva.

WEBP

I-WEBP ixhasa ukungafihli kunye nokunyanzeliswa kwelahleko kunye nokungalahlekiyo. Ihlala ivelisa iifayile ezincinci kunePNG ezikumgangatho ofanayo. Inkxaso ekhulayo kuzo zonke iibrowser kunye neeapps.

GIF

I-GIF ixhasa kuphela ukungafihli okubini: ipixel iyabonakala ngokupheleleyo okanye ayicacanga ngokupheleleyo. Akukho ngcathu elubala. Ilinganiselwe kwimibala engama-256, ngoko ayifanelekanga kwiifoto.

I-TIFF

I-TIFF ixhasa amatshaneli e-alpha kwaye isetyenziselwa ukuhamba komsebenzi kobuchwephesha. Ixhaphake kakhulu ukuhanjiswa kwewebhu ngenxa yobukhulu beefayile.

HEIC/HEIF

I-HEIC ixhasa ukungafihli kwaye yifomati engagqibekanga kwii-iPhones ezininzi. I-QuickRemove yamkela i-HEIC njengegalelo kwaye inokuvelisa iziphumo ezicacileyo kwi-PNG okanye kwi-WEBP.

Iifomathi EZINGAXHASI KUNGASENZI

IJPG/JPEG ayikuxhasi ukungafihli. Iindawo ezicacileyo zikholisa ukuzaliswa ngombala oqinileyo (ohlala umhlophe) xa uguqulelwa kwifomati exhasa ialpha. Ukuba ufuna ukungafihli, thumela ngaphandle njenge-PNG okanye i-WEBP.

I-BMP inenkxaso elinganiselweyo yealpha kwezinye iinguqulelo kodwa ayifane isetyenziswe kwimifanekiso ecacileyo. Namathela kwi-PNG okanye kwi-WEBP ukuze ihambelane nendalo iphela.

Isebenza njani ukungafihli kuYilo kunye neWebhu

Web

Iibrowser zibonelela ngeePNGs ezicacileyo kunye neeWEBPs phezu kwayo nayiphi na imvelaphi - emhlophe, enemibala, okanye igradient. Ipateni yebhodi yokukhangela oyibonayo kwabanye abahleli sisalathiso esibonakalayo; ayibonakali kumfanekiso wokugqibela.

Uyilo lweSoftware

Izixhobo ezifana nePhotoshop, Figma, kunye neCanva inkxaso yomaleko ngokucace. Iindawo ezicacileyo zivumela iileya ezisezantsi zibonakale. Thumela njenge-PNG (okanye i-WEBP) ukugcina ukungafihli xa uhambisa impahla phakathi kwee-apps.

Shicilela

Iprinta ayinayo "transparency" ngendlela efanayo - awukwazi ukushicilela nto. Kushicilelo, iindawo ezibonisa elubala mhlawumbi zishiywe njenge "knockout" (akukho-inki) okanye zizaliswe ngombala ongasemva ochaziweyo. Xoxa nomboneleli wakho woshicilelo.

Iingcamango Eziphosakeleyo eziqhelekileyo

"Imvelaphi emhlophe = transparent"

Hayi. Imvelaphi emhlophe imhlophe opaque. Ukucaca okuyinyaniso kuthetha ukuba akukho mbala - ipixel ayibonakali. Abanye abaqalayo babhidanisa i-backdrop emhlophe kunye nokungafihli; zahlukile.

"Zonke iifomathi zemifanekiso zixhasa ukungafihli"

Hayi. JPG ayikhe ixhase ukungafihli. Sebenzisa i-PNG okanye i-WEBP xa uyifuna.

"Ukungafihli kwandisa ubungakanani befayile kakhulu"

Iifayile zePNG ezinokufihlwa zinokuba nkulu kuneJPG, kodwa itshaneli yealpha ngokwayo ayisoloko iphinda kabini ubungakanani. Uxinzelelo luyanceda. I-WEBP ihlala ifikelela kwiifayile ezincinci ezicacileyo kunePNG.

Ukususa ngokukhawuleza kunye nokuNgafihli

I-QuickRemove yi-Windows desktop app eyenza imifanekiso ecacileyo ngokususa imvelaphi. Ikhupha i-PNG (kwaye inokusebenza kunye ne-WEBP) ukugcina i-alpha epheleleyo. Ukusikwa kwakho kunokubekwa kuyo nayiphi na imvelaphi kwizixhobo zoyilo, iiwebhusayithi, okanye ukuprintwa komsebenzi. Konke ukusetyenzwa kwenzeka ekuhlaleni-imifanekiso ayisoze iyishiye iPC yakho.
