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.

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.

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.

Ingaba i JPEG Filters iya kunyusa ubunjani be JPEG 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 eziluncedo ngokwakho kunokuba ufumana okumiselweyo okumiselweyo.

Ndingaqhuba i JPEG Filters 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?

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 lokucoca i-metadata phambi kokukhuphela ukuba ujongene nokupapasha ifayili.

Ingaba i JPEG Filters ibiza nantoni na?

Umhlathi JPEG Filters ukhululekile ngaphandle kwe-akhawunti, akukho phawu lwamanzi kwimveliso kwaye akukho mnatha wobhaliso phambi kokukhuphela. Ukukhuphela kususwa ngokuzenzekelayo ngexesha elifutshane emva kokuba umsebenzi ugqibile.

Kutheni i WebM inxuwa liququzelela JPEG Filters?

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 Filters 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 Filters 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 Filters 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. Oku kuqala kwinyani enye malunga nefomati le nxuwa libizwa emva: I-WebM yi-VP9 okanye i-AV1 ene-Opus yesandi, esiza kuyenza ikhowudi ikwi-browser kodwa esiya kuyenza ikhowudi kwi-desktop editors xa irhweba ngaphakathi.

Ndifuna i-akhawunti, kwaye ngaba kukho into egcinwa?
