Indlela yokufaka izihluzi ku JPEG

1 Layisha phezulu i JPEG images ofuna ukuyiphatha.

2 Khetha iziphumo zakho - i-greyscale, sepia, i-invert, i-blur, i-sharpen, i-brightness, i-contrast ne-saturation - kwaye umisele amandla nganye.

3 Sebenzisa zonke ezi zinto kwindlela enye edlulayo kunokuba uqhube isixhobo ngokuphindaphindayo, oku kukwenza ukulimala okubonakalayo.

4 Layisha ezantsi ifayili ecociweyo JPEG, kwaye ugcine eyakho eyamva nje: le yindawo ekuphela kwayo yokubuyisela oyenzayo.

JPEG Iicebo lokucoca ulwelo Imibuzo ebuzwa rhoqo

Ziziphi iziphumo ezifumanekayo?

Isikali esingwevu, i-sepia, ukujika, ukuqaqamba, ukuqaqamba, ukukhanya, u kontrast kunye nokulungiswa kokulungiswa. Ziyakwazi ukudityaniswa, kwaye ukudityaniswa kwabo kwindlela enye kungcono kunenkqubo yesixhobo ephindaphindwayo.

Ingaba ifomati yombhalo itshintsha indlela icebo lokucoca ulwelo elibonakala ngayo?

Iyakwazi. I-JPEG yi-codec efanayo ne-JPG phantsi koluhlu olude — i-DCT efana ne-pipeline, i-quantization table efana ne-quantization table, akukho nto malunga nee-pixels ezitshintsha ngegama lefayili. Ubunzulu bombala kunye nemodeli yengqokelela yezixhobo ngokukodwa igqiba ukuba i-gradient okanye ukuqaqamba kungabonakaliswa njani ngokulula.

Nantoni na ekhethekileyo kwi JPEG ekufuneka igcinwe engqondweni?

Ewe - i.jpeg ne.jpg izilungiso ziyi-bitstream efanayo, ngoko akukho nto apha esebenza ngokuhlukileyo kune-.jpg — kuphela igama lefayili litshintsha. Oku kubaluleke kakhulu xa kuthelekiswa nento ebonakala icocekile nento ebonakala ibandayo.

Ndingaqhuba i JPEG Iicebo lokucoca ulwelo kwi JPEG images ezininzi ngaxeshanye?

Ewe. Nciphisa iqela lonke kwindawo yolayisho phezulu kwaye ziphole ngokuthe ngqo ngemimiselo efana nayo - le yisizathu esiphambili sokwenza oku kumkhangeli zincwadi kunokuba yifayile enye ngexesha kumhleli. Iiakhawunti ezikhululekileyo ziqhuba ifayile enye kwiqela; i pass iphakamisa loo nto.

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

Oku kuxhomekeke kwisixhobo. Ukucofa kunqakraza i-EXIF kunye neprofayili yombala ofakwe ngaphakathi ukulondoloza isithuba, ngelixa uhlela njengenguqulo yobungakanani okanye ujikeleziso ungagcina. Akukho mmiselo kule phepha oza kukhetha, ngoko khangela ifayile ngombonisi we-metadata phambi kokukhutshwa ukuba indawo ye-data ibalulekile.

Ingaba i JPEG Iicebo lokucoca ulwelo ibiza nantoni na?

JPEG Iicebo lokucoca ulwelo ikhululekile ngaphandle kwe akhawunti kwaye idibanisa akukho phawu lwamanzi. Ulayisho phezulu neziphumo zicinywa ngokuzenzekelayo malunga neyure ezi 24 emva komsebenzi, oshiya ixesha lokulayisha ezantsi iziphumo.

Kutheni i WebM inxuwa liququzelela JPEG Iicebo lokucoca ulwelo?

WEBM.to ibekwe phantsi kwebhokisi ye-web evulekileyo ekhethiweyo — VP9 okanye AV1 nge-Opus audio, ikhowudiwe ngokusemthethweni ngazo zonke iziphequluli zexesha elidlulileyo kwaye ayifuni iplugin, ilayisensi okanye umdlali. Ividiyo yimeko apho izithuthi ezijikelezayo ezingaphezulu zibuhlungu kakhulu - iifayile zikhulu kwaye zonke ukukhuphela zibiza iiyure ezilungileyo. Ukusebenza JPEG Iicebo lokucoca ulwelo kwindlela yokuhambisa i-pipeline efanayo njengeeguqulelo kuthetha ukuba ukukhuphela omnye ugubungela umsebenzi wonke endaweni yokukhuphela omnye kwisixhobo ngasinye.

Ndiza kwenza ntoni ngeziphumo xa i JPEG Iicebo lokucoca ulwelo igqityiwe?

Umguquli kule ndawo uhambisa ividiyo phakathi kweWebM, MP4, MKV, MOV kunye nezinye, okanye utsala umculo ophumayo ngokupheleleyo, ngaphandle kokukhuphela enye. Ukulandelela okunjalo kubaluleke kakhulu kwividiyo kunezinye iindawo: ukuphinda- ukhowudi nganye kuhlobo olunye, ngoko ke, xa kuncinci kwabo phakathi kombhalo kunye nefayile opapashayo, ibonakale ingcono.

Ingaba JPEG Iicebo lokucoca ulwelo apha isixhobo esifanayo esisebenza kumasayithi afana nalowo?

Iinjini zinikezelwa - i-ffmpeg enye yokwakha nge x264, x265 ne libvpx, abasebenzi abafanayo, amaqondo afanayo. Oku WebM inxuwa lidibanisa kukubona kwiinqanawa ne codecs: ezi zidibanisa zidlala naphi na, ezifuna ukuphinda zikhowudi kwaye ezi zingakopela ngokulula.
