TIFF ukuba JPG Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-TIFF ibe yi-JPG ngaphandle kokulahlekelwa umgangatho womfanekiso?

Layisha phezulu ifayili yakho ye TIFF kwaye umguquli wethu usebenzise ukuphuculwa komgangatho owaziyo ifomati ye JPG imveliso. Kwiinjongo ezingalahlekiyo (PNG, TIFF, BMP) yonke i-pixel igcinwa nge-bit-per-bit; kwiinjongo ezilahlekiyo (JPG, WebP) ungalungisa isizathu somgangatho (okungagqibekanga 90) phambi kokukhuphela. I-TIFF yindawo yokugcina engaphezulu kwe-codec: inokuphatha i-data engacinezelwanga, i-LZW, i-ZIP okanye nakwi-JPEG, ukuya kuthi ga kwi-32 bits kwisiqhagamshelanisi ngasinye, ngeephepha ezininzi kwifayile enye. I-JPG ilahlekile: umfanekiso uguqulwa nge-DCT, i-quantized, kunye ne-entropiya-ekhowudiweyo, ngeqhosha lomgangatho elilawula ukuba kuphi okuninzi okulahlekileyo.

Ithini into eyenza amanqanaba efayili yam TIFF?

Ziqhotyoshelweyo, ngokusisigxina, kumfanekiso omnye odityanisiweyo. Iinkqubo zokudibanisa, iziqhoboshi, amanqanaba olungiso kunye nombhalo ohlelayo zonke zilungiswe kwipixels yokugqibela kuba JPG ayinaso isakhiwo sokuba zigcine. Gcina i TIFF njenge-master esebenza kakuhle kwaye uthathe i JPG ngokungqongqo njenge-export. I-TIFF iphatha i CMYK, ubunzulu be-16-bit, i-ICC efakwe ngaphakathi kunye namaxwebhu ephepha elininzi, eli linyaniso le shicilelo kunye nomsebenzi wokuhamba kovimba ofunayo. I-JPG ayinakubonakaliswa ngokucacileyo, ikhupha ngaphezulu xa igcinwa kwakhona, kwaye ivelisa ukutshixa okubonakalayo kumbala othambileyo nombhalo oqaqambileyo.

Ingaba ukubonakaliswa okubonakalayo kuya kuqhubeka nokutshintsha TIFF ukuya ku JPG?

Hayi - JPG ayinasiqhagamshelanisi se-alpha, ngoko imimandla ecacileyo idityaniswe nombala wokungasemva, omnyama ngaphandle kokuba uyitshintshile. Oku kubangela uxinzelelo oluqhelekileyo oluthile kule kuguqulelo: ilogo ebonakala icocekile kwiphepha elimnyama lifika ngebhokisi emhlophe ejikelezayo. Misela umbala omnyama ukuze uthelekise apho umfanekiso uhlala khona, okanye khetha injongo egcina i-alpha.

Ingaba ndiya kulahlekelwa yintoni ngomgangatho xa ndisuka kwi TIFF ukuya kwi JPG?

Kwi umgangatho 80- 85 utshintsho alubonakali kumgama wokubona oqhelekileyo kwaye ifayile ihlala iphantsi nge 60- 80%. Ukubamba kukuba yindlela enye: ukubuyisela ukugcina i JPG ngokuphindaphinda idibanisa i artefacts ixesha ngalinye. Gcina i TIFF njenge master kwaye uphinde uphinde uvule i JPG ukusuka kuyo xa ufuna ubungakanani obutsha.

Ingaba i JPG igcina i-EXIF data evela kum TIFF?

Ngokungagqibekanga ewe, apho naphi na apho injongo ifuna ukubekwa khona - imodeli yekhamera, izicwangciso zokubonisa, iinwele kunye neGPS ikhowudi zihamba zonke. I-GPS yindawo efanele ucinga ngayo: ukuba umfanekiso uzakupapashwa, sebenzisa ukhetho lwe-strip-metadata ukuze ungasazibonisi apho umfanekiso uthathwe khona. I-TIFF yifomati yefayili yomfanekiso ophawulwe ukusukela ngo-1986, kwaye yifomati yokukhangela, yoshicilelo kunye nokugcina iinjineli ezimiselwe.

Ingaba uguqulelo TIFF ukuya ku JPG lugcina ukubonakala ngaphaya?

Ukubonakala ngaphaya kuqhubeka xa JPG yi-PNG, WebP, TIFF, GIF, okanye SVG. Ukutshintsha ukuba yi-JPG kwenza ukuba isiqhagamshelanisi se-alpha sifane nesiqalo esimhlophe — ukuba ufuna ukubonakala ngaphaya, khetha isiphelo esizimelayo esibonisa ngaphaya endaweni ye-JPG. I-JPG yi-JPEG eqhelekileyo ukusukela ngo-1992, kwaye emva kweminyaka emithathu ihlala i-format esetyenziswa ziikhamera ezininzi kunye ne-web sites ezininzi zomfanekiso.

Ingaba i-inkangeleko yam yombala (sRGB / Adobe RGB / CMYK) iya kuhlala i TIFF ukuya ku JPG?

Iiprofayili zombala we-ICC ezifakelweyo zifundwa kumvelaphi TIFF kwaye zidityaniswe kwakhona kwi-JPG yemveliso apho ifomati ixhasa khona (JPG, PNG, TIFF, WebP). Iifomati ezingaxhaswanga yiprofayili zibuyela kwi-sRGB ngenyathelo elilula lokuqinisekiswa.

Ithini into ebangela ukuba i-EXIF metadata iguqulwe TIFF ibe yi JPG?

I-EXIF yekhamera (ISO, i-shutter, i-lens, i-GPS) igcinwa ngokumiselweyo ngexesha TIFF -> JPG xa zombini iifayili zixhasa i-metadata. Sebenzisa utshintshi lobumfihlo ukususa i-metadata phambi kokukhuphela ukuba ufuna ukuthumela imifanekiso ngaphandle kokubekwa kwendawo okanye ukubonisa umnwe wesixhobo.

Ndingaguqula izigidi zeefayili TIFF zibe JPG ngaxeshanye?

Ewe - rhuqa iifayile ezininzi TIFF kwindawo yokulayisha kwaye zifolole ngokuthe tye. Umphakamo osimahla uyamkela i-100 MB ngefayili nganye; i-Premium ayinasiphelo sefayili nganye kwaye iqhuba abasebenzi abathe tye abaninzi, ngoko ke iqela lemifanekiso engama-200 ligqiba ngaphantsi kwemizuzu emibini.

I-TIFF ukuya kwi-JPG ithelekiswa njani ne-Photoshop / i-GIMP kumsebenzi ofanayo?

Uguqulelo lwefomati olulula siqhuba i libpng / libjpeg- turbo / libwebp / ImageMagick imibhobho efanayo umhleli we desktop asebenzisayo, kwi umgangatho ofanayo. Utshintsho kukuba izixhobo ze desktop zivula ifayile enye ngexesha; siyamkela iqela kwaye siqhuba ngokuthe tye kwiseva- ecaleni kwabasebenzayo.

I-JPG iifayili zinee-resolutions kunye nemilinganiselo eziphi?

Ukuziphatha okungagqibekanga kuku 1:1 — i-JPG yakho yemveliso inezinto ezilinganayo ze-pixels njenge-TIFF. Ukuba ufuna ukuguqula ubungakanani njengenxalenye yokuguqula, sebenzisa /resize-image/ emva, okanye ubeke iinzame kwi- /image-pipeline/ utility.

Ingaba i JPG ifayili incinane kangakanani na ukuba ayinazo izinto ezibonakalayo ezibonakalayo?

Kwi-JPG / WebP, umgangatho we-75-85 uhlala uvelisa i-JPG 60-80% encinci kune-TIFF ngaphandle kotshintsho olubonakalayo kumgama wokujonga oqhelekileyo. Kwi-JPG engenanto (PNG, TIFF), lindele ukonga okuncinci — ngokuqhelekileyo 5-30% nge-deflate / LZW yokucinezela engcono kuneleyo umboneleli sele uneyo. I-JPG icinezela imifanekiso ebonakalayo ngokumangalisayo kwaye ifundeka ngazo zonke izixhobo, umkhangeli zincwadi nomshicileli okhoyo.

TIFF

Iifayile zeTIFF zixhasa ubunzulu be-bit ephezulu kunye noxinzelelo olungenalahleko, zilungele ukufota kunye nokuprinta ngobuchwephesha.

JPG

Iifayili ze-JPG zisebenzisa ukucinezela okulahlekileyo okulungelelanisiweyo kwiimifanekiso, zibonisa ubungakanani befayili encinci ngelixa zigcina inqanaba elibonakalayo.
