Indlela yokulungisa JFIF kwi-intanethi

1 Layisha phezulu i JFIF images ofuna ukusebenzela kuyo; ifayili ivula kwi-canvas eguqulelweyo kwi-browser yakho ngaphandle kokufaka ntoni na.

2 Ukusika, ukujika, ukuguqula ubungakanani, ukuzoba, ukongeza umbhalo kunye nemifanekiso, okanye ukulungisa umbala - utshintsho ngalunye luya kukopi esebenza, alunakuze lufike kwi-upload yakho.

3 Imboniselo yangaphambili yeziphumo kubungakanani obupheleleyo phambi kokuba ubeke isandla.

4 Rhweba ngaphandle kwakhona ukuya kwi JFIF, okanye kwifomati engalahlekiyo endaweni yoko ukuba uhlala usenza utshintsho.

Umhleli we JFIF Imibuzo ebuzwa rhoqo

Ingaba ifomati yefayili imisa okunokwenziwa ngumhleli?

Iyenza. 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. Oku ufomati ingabonisa imida into onke umhleli angagcina, apha okanye kwi desktop.

Nantoni na ekhethekileyo kwi JFIF kumhleli?

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. Kubalulekile ukwazi phambi kokuba urhwebe ngaphandle ngaphezulu kokopi yakho ekuphela kwayo.

I-Umhleli we JFIF ivumela njani ukuba ndihlela ngaphandle kokufakela nantoni na?

Ngokucacileyo, i JPEG ikhowudiwe kabini kwi RGB canvas, utshintsho ngalunye owenza luya kuwela kuloo canvas kunokuba kwifayile, kwaye i quantizer iqhuba ngokuchanekileyo kabini xa urhweba ngaphandle - oko kukuthi kutheni uhlela apha awunakudibanisa ukulimala kohlobo ngendlela elishumi yohlela- kwaye- ugcine kwakhona ijikelezo kwi desktop app. Umgangatho wokuhlela yi-browser, ngoko akukho nto yokufakela kwaye akukho layisenisi yokuyigcina.

Yintoni endinokuyitshintsha?

Ukusika, ukujika, ukujika, ukuguqula ubungakanani, ukuzoba, ukongeza umbhalo kunye neendlela, kwaye usebenzise izihluzi kunye nokulungiswa kombala. Zonke izinto zisetyenziswa kwikopi esebenza, ngoko ke ifayile oyikhuphelayo ayizukuguqulwa kwindawo.

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 Umhleli we 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 Umhleli we 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 Umhleli we 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 Umhleli we 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.
