Ukusika PNG Imibuzo Evame Ukubuzwa

Ingabe ifomethi yami yomsuka ishintsha indlela okuhlolwa ngayo?

Ingaba. I-PNG i-DEFLATE engalahlekelwanga nge-8-bit alfa channel ephelele ne-16-bit ububanzi obukhethwayo, ngakho-ke ayikwazi ukuncipha uma igcinwa futhi kodwa itholakale enkulu kuma-contents wezithombe. Lokhu kuchaza ukuthi ngabe ukuvuna kuyisisebenziso se-pixel esicacile noma ngabe ifayela kumele liphinde liphinde likhiwa.

Ingabe kukhona okuthile okukhethekile ku PNG okudinga ukukwazi ngaphambi kokuba ngikhulise?

Yebo — Akukho sinqumlisi somgangatho esingakwazi ukukhohlwa — i-PNG ihamba ngezinyawo ngokucophelela, ngakho into eyodwa kuphela eguqula izindleko zakho yisayizi yefayela. Lolu uhlobo lwemininingwane ebonisa kuphela ngemuva kokubhala ngaphezulu okungaphambilini.

Indlela i Ukusika PNG ekhetha ngayo futhi ihlehlise indawo?

Ngokucacile, i-pixel rectangle okhetha ibhalwe ngokuqondile ngaphandle futhi ngaphandle kokuphinda usebenzise isigaba sokungenisa-lwazi, ngakho-ke ukuvuna isithombe esingalahleki kuyinhlanganisela yendawo ehambisanayo yokuqala, i-byte nge-byte. Uzosusa indawo oyifunayo ngokuqondile kwimboniso, noma ubhale ngokucacile ama-pixels axhunywe uma uwazi.

Ingabe ngingakwazi ukugoba ngezinga lokubuka eliqinile?

Yebo. Chofoza okukhethiwe ku-1:1, 4:3, 16:9 noma noma yisiphi isibalo esijwayelekile bese ushaya ngokukhululekile ngaphakathi kwesimo esicindezelayo - lokhu kuyindlela othola ngayo isithombe esiphelele esilungele isikhala sohlelo olufanayo ngaphandle kokulinganisela noma yini.

Ingabe isixhumi se-alpha sizohlala?

Yebo. I-PNG ne-TIFF zifaka isixhumi esigcwele se-8-bit alfa futhi zigcinwa kuze kube yilapho. Zihlanganiswa kuphela uma ubeka inhloso yohlelo olungena-alpha, lapho ama-pixels acacile ehlanganisana emhlophe.

Yini engikwazi ukuyifaka ku Ukusika PNG?

PNG, BMP ne TIFF yifomethi ye-raster engalahlekelwa yisimo esiphatha ngokuqondile, futhi ama-lossesy sources (JPG, WebP, GIF) asebenza futhi uma ufuna ukuba kulowo mhlangano. I-TIFF enekhasi elilodwa noma eliningi itholakale futhi iphathwa ikhasi ngekhasi.

Ingabe kunesilinganiselo sobukhulu behele ku Ukusika PNG?

Yebo: ama-akhawunti amahhala asebenza izithombe kuze kube yi-5 MB ngayinye; ama-sources angeke alahlekelwa yilutho afinyelela esiphethweni ngokushesha kunama-photographs, ngoba akukho okuthunyelwe okwamanje. Uma ungaphezu kwayo, ukushintshana ku-PNG kuqala kuvame ukunethezeka ngokwayo — i-BMP ivame ukube yiminyaka eyisithupha kuya kweziyishumi ubukhulu besithombe esifanayo njenge-PNG.

Ingabe Ukusika PNG izonciphisa ukhwalithi ye PNG images yami?

Akukho. Umsuka ongenalutho ujikeleza-uhambe nge-bit-efanele, ngakho-ke uma ungacela ngokucacile ifomu lokukhishwa elinalutho ama-pixels abuyela emuva yi-pixels asuka ngaphakathi. Lokhu kuyisizathu esiphelele sokuqhubeka nokusebenza kulolu mndeni ngenkathi uqhubeka nokulungisa.

Kungani isayithi elisha lefomethi lisebenza Ukusika PNG?

WEBP.to ifakwe ngokuya ngendawo emisha yokushintshana kwazo zonke izilungiselelo ezidala: ifomu elilodwa elikwenza i-lossy, lossless, alpha ne-animation, futhi lihlala lincane kune-JPEG noma i-PNG eyavela kuyo. Abantu bafika lapha bethathe isinqumo sokuthi amaphutha adlulele abiza i-bandwidth, futhi lo sinqumo siphakamisa isikhala: yini ubukhulu, yini ubuhle, yini ekwenzeni ukubukeka. Ukusika PNG ku-upload efanayo ne-akhawunti efanayo ngakho-ke lezi mibuzo ziphendulwa endaweni eyodwa.

Uma i Ukusika PNG iphume, yini efanele kwenziwe ngemuva?

Umguquli kule ndawo uhambisa izithombe ku-WebP, PNG, JPG ne AVIF, lapho ukhetha khona ukuthi ihele elincane lizolahlekelwa yimiboniso eminingi. Ukwenza lokhu ngokulandelana kubaluleke kakhulu: khetha ama-pixels kuqala futhi ibhokisi ngemuva, ngoba ibhokisi liyisinqumo esiphansi futhi ama-pixels abiza kakhulu.

Ingabe amasayithi afana nawo asebenza ngento ehlukile?

Ama-engine afana — ama-library afanayo, abasebenzi abafanayo, ama-caps afanayo. Okuhlukile ukuthi umbono uxhunywe, futhi umbono uhlala lapha ku-property yefomethi lendawo ibizwa ngemuva: i-.webp efana nengxenye ingagcina i-VP8 elahlekile, elahlekile, noma i-animated, ngakho-ke indlela yokusebenza efanele isinqunywa ngefayela ngalinye ngaphezu kwengxenye ngayinye.

Yini ezoba nehele lami, futhi ngabe i-akhawunti idingeka?
