Ukuqonda Ukungafihli Ezithombeni Zedijithali

Kuyini Ukungafihli?

Ezithombeni zedijithali, ukucaca kusho ukuthi amanye amaphikseli angaba ngokwengxenye noma angabonakali ngokuphelele. Uma ubeka isithombe esikhanyelayo kungemuva elinemibala — iwebhusayithi, idizayini, noma esinye isithombe — izindawo ezibonisa ngale zibonisa noma yini engemuva kwazo esikhundleni sombala oqinile.

Ukubonisa ngale kubalulekile kumalogo, ukusikwa komkhiqizo, izimbondela, nanoma iyiphi inhlanganisela lapho ufuna isihloko sakho sihlangane sibe umongo omusha. Ukususa ingemuva kudala obala ngokwenza ingemuva langempela lingabonakali.

Isiteshi se-Alpha

I-RGB vs RGBA

Izithombe eziningi zisebenzisa i-RGB: iphikseli ngalinye linenani Elibomvu, Eliluhlaza, neliluhlaza okwesibhakabhaka elichaza umbala walo. Izithombe ezibonisa ngale zengeza inani lesine: Alpha. I-RGBA isho Okubomvu, Okuluhlaza, Okuluhlaza okwesibhakabhaka, kanye ne-Alpha. Isiteshi se-alpha sinquma ukuthi iphikseli ngayinye i-opaque noma obala kangakanani.

Amanani e-Alpha

I-Alpha ivamise ukugcinwa njengenombolo esuka ku-0 kuye ku-255 (noma u-0% ukuya ku-100%). 0 = obala ngokugcwele (okungabonakali). 255 = i-opaque ngokugcwele (okuqinile). Amanani aphakathi adala ukubonakala kwe-semi-transparency — awusizo emaphethelweni athambile, izithunzi, nemiphumela yengilazi.

Amafomethi Asekela Ukungafihli

I-PNG

I-PNG isekela i-alpha egcwele (8-bit noma 16-bit). Kuyifomethi evame kakhulu yezithombe ezibonisa ngale. I-PNG ayilahleki, ngakho imiphetho ebonisa ngale ihlala icwebile. Le yifomethi evamile yokuthekelisa yokususwa kwangemuva.

WEBP

I-WEBP isekela obala ngakho kokubili ukuminyanisa okulahlekile nokungalahleki. Ngokuvamile ikhiqiza amafayela amancane kune-PNG ngekhwalithi efanayo. Usekelo olukhulayo kuzo zonke iziphequluli nezinhlelo zokusebenza.

I-GIF

I-GIF isekela kuphela ukubonisa ngale kanambambili: i-pixel isobala ngokuphelele noma i-opaque ngokugcwele. Akukho ukubonakala kwe-semi-transparency. Ikhawulelwe kumibala engu-256, ngakho-ke ayilungele izithombe.

I-TIFF

I-TIFF isekela iziteshi ze-alpha futhi isetshenziswa ekuhambeni komsebenzi okuchwepheshile. Okujwayelekile kancane ekulethweni kwewebhu ngenxa yosayizi bamafayela amakhulu.

I-HEIC/HEIF

I-HEIC isekela obala futhi iyifomethi ezenzakalelayo kuma-iPhones amaningi. I-QuickRemove yamukela i-HEIC njengokufakiwe futhi ingakhipha imiphumela ebonisa ngale ku-PNG noma ku-WEBP.

Amafomethi Angesekeli Ukungafihli

I-JPG/JPEG ayikusekeli ukubonisa ngale. Izindawo ezibonisa ngale zivamise ukugcwaliswa ngombala oqinile (ngokuvamile umhlophe) uma uguqulwa usuka kufomethi esekela i-alpha. Uma udinga ukubonisa ngale, thumela njenge-PNG noma i-WEBP.

I-BMP inokusekelwa kwe-alpha okulinganiselwe kwezinye izinhlobo kodwa ayivamisile ukusetshenziselwa izithombe ezibonisa ngale. Namathela ku-PNG noma ku-WEBP ukuze uhambisane nendawo yonke.

Ukuthi Ukukhanyela Kusebenza Kanjani Kudizayini nakuwebhu

Iwebhu

Iziphequluli zinikeza ama-PNG nama-WEBP asobala ngaphezu kwanoma isiphi ingemuva — esimhlophe, esinemibala, noma i-gradient. Iphethini yokuhlola oyibona kwabanye abahleli iyinkomba nje ebonakalayo; ayiveli esithombeni sokugcina.

I-Design Software

Amathuluzi afana ne-Photoshop, i-Figma, ne-Canva isekela izendlalelo ezinokukhanyela. Izindawo ezisobala zivumela izendlalelo ezingezansi zibonakale. Khipha njenge-PNG (noma i-WEBP) ukuze ulondoloze obala lapho uhambisa izimpahla phakathi kwezinhlelo zokusebenza.

Phrinta

Ukuphrinta akunakho "okungafihli" ngendlela efanayo — awukwazi ukuphrinta lutho. Ukuphrinta, izindawo ezisobala zingashiywa "njengokushaywa" (awukho uyinki) noma ugcwaliswe ngombala okhethiwe wangemuva. Xoxa nomhlinzeki wakho wokuphrinta.

Imibono Eyiphutha Evamile

"Ingemuva elimhlophe = transparent"

Cha. Ingemuva elimhlophe limhlophe opaque. Ukungafihli kweqiniso kusho ukuthi awukho umbala — iphikseli ayibonakali. Abanye abasaqalayo badida ingemuva elimhlophe nokukhanyela; bahlukene.

"Wonke amafomethi ezithombe asekela ukubonisa ngale"

Cha. I-JPG ayilokothi isekele ukubonisa ngale. Sebenzisa i-PNG noma i-WEBP uma uyidinga.

"Ukubonisa ngale kwandisa usayizi wefayela kakhulu"

Amafayela e-PNG abonisa ngale angaba makhulu kune-JPG, kodwa isiteshi se-alpha ngokwaso asihlali siwusayizi ophindwe kabili. Ukucindezela kuyasiza. I-WEBP ivamise ukuzuza amafayela amancane abonisa ngale kune-PNG.

QuickRemove kanye Transparency

I-QuickRemove iwuhlelo lokusebenza lwedeskithophu ye-Windows oludala izithombe ezisobala ngokususa ingemuva. Ikhipha i-PNG (futhi ingasebenza ne-WEBP) ukuze ilondoloze i-alpha egcwele. Ukusikwa kwakho kungabekwa kunoma iyiphi ingemuva kumathuluzi edizayini, amawebhusayithi, noma ukuphrinta komsebenzi. Konke ukucubungula kwenzeka endaweni - izithombe azilokothi zishiye i-PC yakho.
