Indlela yokujika JFIF

1 Layisha phezulu i JFIF images yakho uze ulinde ukujonga phambi koshicilelo ukuba kuvele.

2 Rhuqa ngaphandle ummandla ofuna ukuwugcina, okanye utshixe ukhetho kwi 1:1, 4:3 okanye 16:9 kwaye urhoxise ngokukhululekileyo ngaphakathi kolu hlobo loqhagamshelwano.

3 Qinisekisa ukutywina - i-rectangle efanayo isetyenziswe kwifayile nganye olayishe kuyo, oko kukuthi indlela emiselweyo ephelela ngokuhambelana ngokuqinisekileyo.

4 Layisha ezantsi ifayili ecutiweyo JFIF, ngazo zonke izinto ezingaphandle kwesakhelo ezilahlekileyo.

Ukusika JFIF Imibuzo ebuzwa rhoqo

Ingaba ifomati yam yombhalo itshintsha indlela eziphatha ngayo i-crop?

It can. I-JFIF yi-JPEG eqhelekileyo ehamba ngesantya esincinci phantsi kokuqala ko-1992 okubhaliweyo okuphezulu kwephepha okutshintshelana, oko kubangela ukuba abanye ababonisi babonise njengomfanekiso oqhelekileyo kwaye iikhamera zihlala ziyikhupha. That decides whether the crop is a pure pixel operation or whether the file has to be rebuilt around it.

Nantoni na ekhethekileyo kwi JFIF ekufuneka ikwazi phambi kokuba ndityhale?

Ewe — ababhali abaninzi babhala kwakhona i-JFIF njenge-JPEG eqhelekileyo xa begcina, ngoko ke gcina okubhaliweyo okuphambili ukuba uluhlu lwe-.jfif lubalulekile nakweyiphi na into esebenzisa ifayile. Loluhlobo lweenkcukacha ezibonisa kuphela emva kokuba ubhale ngaphezulu okubhaliweyo okubhaliweyo.

I-Ukusika JFIF ikhetha kwaye icima indawo njani?

Ngokucacileyo, i-crop isetyenziswe kumfanekiso oguqulwe kwikhowudi kwaye i-result iphinde ikhowudiwe, ngoko ibiza udidi olunye; apho i-crop iqala khona ukuwela kuma-8-pixel MCU ama-boundaries i-encoder ingagcina i-original blocks kwaye ixabiso liphela. Urhoxisa ummandla ofuna ukuwubona ngokuthe ngqo kwimboniselo, okanye ubhale ngokuchanekileyo i-pixels ezihambelanayo ukuba sele uyazi.

Ndingatyhila njani i-aspect ratio?

Ewe. Tshixa ukhetho kwi 1:1, 4:3, 16:9 okanye nayiphi na i-ratio eyenziwe ngokwezifiso kwaye urhoxise ngokukhululekileyo ngaphakathi kolu thintelo - oko kukuthi, indlela ofumana ngayo iseti yemifanekiso elungele zonke i-slot yobeko olufanayo ngaphandle kokulinganisela nantoni na.

Ithini into ebangela ukuba i-EXIF ne-data yeprofayili yombala isebenze?

Ikhamera EXIF (ISO, i-shutter, i-lens, i-GPS) kunye ne-ICC efakwe kwiprofayili idluliselwa ngokumiselweyo, kuba ukulahla iprofayili kwenza umbala utshintshe xa uphinda urhweba ngaphakathi. Sebenzisa ukhetho lokhuseleko lokususa i-metadata phambi kokukhuphela ukuba ujongene nokupapasha ifayili.

Yintoni endinokuyilayisha kwi Ukusika JFIF?

Nantoni na ekufumaneni usapho lwe-raster - JPG, JPEG, JFIF ne-WebP - kunye neefomati ezingalunganga (PNG, BMP, TIFF) ukuba ufuna ukuzidibanisa kwiqela elinye. Ifomati ifundwa kwisihloko sefayili, hayi kwisiphelo, ngoko ke umfanekiso ogciniweyo nge-suffix engafanelekanga uhlala udlula.

Ingaba kukho umda wobungakanani befayili kwi Ukusika JFIF?

Ewe: i-akhawunti ekhululekileyo iqhubekeka imifanekiso ukuya kwi-5 MB nganye, equka ngokucacileyo yonke ikhamera ye-JPG kunye nefowuni yomfanekiso; umsebenzi ukwenziwa yi-libjpeg-turbo ne-libwebp, iilayibrari ezifanayo umhleli we-desktop uqhagamshelana nazo. Iifayili ezinkulu zizinto ezi-1 ezimfutshane ezikhululekileyo eziza kukuthintela, kwaye umda yifayili nganye kunokuba yiqela ngalinye.

Ingaba i Ukusika JFIF iya kunyusa ubunjani be JFIF images yam?

Umthombo olahlwayo sele uyimpumelelo yendlela enye yokugqitha, kwaye nayiphi na imisebenzi efuna ukubuyisela ikhowudi idibanisa enye. Xa umsebenzi ungakwenziwa ngaphandle kokucofa i-pixel data siyenza endaweni, kwaye apho ayikwazi khona ukhetha umgangatho wezinto ozithandayo ngokwakho kunokuba ufumana okumiselweyo okumiselweyo.

Kutheni i-site ekwifomati entsha iqhuba Ukusika JFIF?

WEBP.to ibekwe phantsi kotshintsho olutsha lwezo zombini iinkqubo ezingagqibekanga: ifomati enye eyenza ilahlekile, engalahleki, i-alpha kunye nobuchule, kwaye ihlala incinci kune-JPEG okanye i-PNG eyavela kuyo. Abantu bafika apha begqibe ukuba iimfuno eziqhelekileyo zakudala zibiza ibhandewidth, kwaye loo sinqumo sikhupha ngokuzenzekelayo isiphelo: ubungakanani obunjani, umgangatho onjani, into eyenza ukuba ibonakale. Ukusika JFIF ikwi-upload efanayo ne-akhawunti efanayo ukuze ezo mibuzo ziphendulwe kwindawo enye.

Xa i Ukusika JFIF iphumeze, yintoni ekufuneka yenziwe emva koko?

Umguquli kule ndawo uhambisa imifanekiso ukuya nakwi WebP, PNG, JPG ne AVIF, apho ugqiba khona ukuba ifayile encinci ifanele ilahle iiseva ezidala. Ukwenza oku ngokulandelana okubalulekileyo: khetha ii-pixels kuqala kwaye isiqulathi-zifayili emva koko, kuba isiqulathi-zifayili sigqibo esiphantsi kwaye ii-pixels zibiza kakhulu.

Ingaba iinxuwa ezifanayo ziqhuba into eyahlukileyo?

Iinjini zifana - iilayibrari ezifanayo, abasebenzi abafanayo, iziqhoboshi ezifanayo. Okuhlukileyo kumbono odityanisiweyo, kwaye umbono apha uhlala kwipropathi yefomati le ndawo ibizwa emva: i-.webp efana ne-extension ingagcina i-VP8 frame elahlekile, enye engalahlekiyo, okanye udweliso, ngoko ke indlela yokusebenza efanelekileyo igqibwa ngefayili nganye kunokuba yi-extension nganye.

Yintoni eyenza ifayili yam, kwaye ngaba i-akhawunti ifuneka?

Akukho akhawunti, kwaye akukho nto igcinwa: ulayisho lususwa abasebenziyo emva komsebenzi ugqiba, kwaye akukho nto ivavanywa, idweliswe okanye iqulathe isalathisi. Iiakhawunti zikhona kuphela kwimbali kunye nobungakanani beqela.
