JPG kuya TIFF Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyiguqula kanjani i-JPG ibe yi-TIFF ngaphandle kokulahlekelwa ubuhle besithombe?

Layisha phezulu ihele lakho JPG futhi umguquli ufaka ukulungisa umgangatho okwaziyo ifomu le TIFF. Ukungabi nalutho TIFF (PNG, TIFF, BMP) wonke ama-pixel agcinwa; ukungabi nalutho TIFF (JPG, WebP) ungalungisa umphumela womgangatho ngaphambi kokulayisha. I-JPG ilahlekelwa yisimo: isithombe siguqulwa nge-DCT, silinganiselwe, futhi sikhonjiswa nge-entropiya, nge-nobhu wobude olawula ukuthi yini elahlekile. I-TIFF iyindawo yokuqoqa engaphezu kwe-codec: ingagcina idatha engacindezelwanga, i-LZW, i-ZIP noma i-JPEG, kuze kube yi-32 bits ngasinye, ngekhasi eliningi kwifayela elilodwa.

Ingabe ngizothola ukubukeka okucacile uma isithombe si TIFF?

I-TIFF isekela le fomethi, kodwa ukuguquka akukwazi ukuyenza. I-JPG ayinaso isixhumi se-alpha, ngakho wonke ama-pixels kufaka phakathi isizinda sifika sigcwele. Sebenzisa /removebackground/ ngemuva kokususa isithako — bese i-alpha channel TIFF inikeza into egcinwa. I-TIFF iphatha i-CMYK, 16-bit ububanzi, i-ICC efakwe ngaphakathi namaprofayili namadokhumende amakhasi amaningi, okuwukuthi okuthile okudingayo ukuphrinta nokugcinwa kwemisebenzi.

Ingabe ukushintsha JPG kuya ku TIFF kuzobuyisela ubunjani obulahlekile?

Akukho. Izinto ezicindezelwe ezifakwe ku JPG manje ziyidatha ye-pixel ejwayelekile, futhi TIFF igcina kahle kunesisusa. Ihele livame ukukhula, ngamanye amaxesha likhula izikhathi eziningi. Kuyinto efanele ukuyenza ngaphambi kokuhlela, ngoba ukuhlela okulandelayo akuzofaka isizukulwane sesithathu sokulimala phezulu. I-JPG ayinayo ukubukeka okucacile, ihamba kancane ngaso sonke isikhathi lapho igcinwa kabusha, futhi ikhiqiza ukuvala okubonakalayo kumbala ophansi nombhalo oqinile.

Ingabe i-TIFF igcina i-EXIF data kusuka ku-JPG yami?

Ngokungajwayelekile yebo, lapho injongo ikhona khona ukuze ibekwe khona - imodeli yekhamera, izilungiselelo zokuveza, ilensi kanye ne-GPS coordinates zonke zihamba phambili. I-GPS iyindawo efanele ukucabanga ngayo: uma isithombe sizoshicilelwa, sebenzisa i-strip-metadata option ukuze ungasakazi lapho isithombe sithathwe khona. I-JPG iyisimo se-JPEG esijwayelekile kusukela ngo-1992, futhi ngemuva kweminyaka emithathu ihlala iyisimo esisetshenziswa amakhamera amaningi namanye amawebhusayithi asebenzisa ama-photos.

Ingabe JPG kuya ku TIFF ukuguqulwa kugcina ukubukeka okucacile?

Ukubukeka okucacile kuqhubeka uma TIFF i-PNG, WebP, TIFF, GIF, noma SVG. Ukushintsha ku-JPG kwenza i-alpha channel ibe mhlophe. Uma ufuna ukubukeka okucacile esinqumweni, bheka ukubonakala okucacile okuqaphelayo TIFF endaweni ye-TIFF=JPG. I-TIFF iyifomethi yefayela lesithombe ephawulwe kusukela ngo-1986, futhi iyifomethi yokuskena, ukushicilela kanye nokugcinwa kwefayela ezimbonini ezijwayelekile.

Ingabe iprofayili yami yombala (sRGB / Adobe RGB / CMYK) izohlala JPG kuya TIFF?

Amaprofayili wemibala we-ICC afakwe ngaphakathi afundeka kusuka ku-JPG futhi axhunywe kabusha ku-TIFF lapho ifomu lixhasa khona (JPG, PNG, TIFF, WebP). Amafomu enza iphrofayli ayixhasi ubuyela emuva ku-sRGB, okugcina amamibala ahambisana nemboniso yamanje.

Yini mayelana ne-EXIF metadata uma uguqula JPG kuya ku TIFF?

Ikhamera EXIF (ISO, i-shutter, i-lens, GPS coords) igcinwa ngokuzenzakalela ngesikhathi JPG → TIFF lapho amafomethi amabili exhasa i-metadata. Sebenzisa ukhetho lokufihla ukususa i-metadata ngaphambi kokulayisha uma ufuna ukuhlanganisa izithombe ngaphandle kokubeka indawo.

Ingabe ngingakwazi ukushintsha amafayela amaningi JPG abe TIFF ngasikhathi sinye?

Yebo — cindezela amafayela ahlukahlukene JPG endaweni yokulayisha bese siwafaka emgodini ngokufanayo. Abasebenzisi abamahhala bathola i-100 MB ngefayela ngalinye; iPremium ayinaso isikhala ngasinye sefayela futhi isebenza nabasebenza ngokufanayo, ngakho-ke isithombe esingu-200 siqediwe ngezansi kwemizuzu emibini.

Ingabe JPG kuya ku TIFF iqhathaniswa kanjani ne-Photoshop / GIMP ngemisebenzi efanayo?

Ukuguqulwa kwefomethi eqondile sisebenzisa i-libpng / libjpeg-turbo / libwebp / ImageMagick pipes efana ne-desktop editor, ngekhwalithi yokuphuma efana. Ushintsho luyi-batch parallel handling — desktop applications open one file at a time; we accept a batch.

Yini isixazululo esizobe sikhona kuhele TIFF?

Okuzenzakalelayo yi-1:1 — TIFF yakho igcina ama-pixels alinganayo we-JPG. Uma ufuna ukuguqula ubukhulu njengengxenye yokuguqulwa, sebenzisa /resize-image/ ngemuva kokuguqulwa, noma uyibeke nge /image-resize/ utility.

Ingabe i TIFF ingancane uma ingabonakali i-artifacts?

I-JPG / WebP, umgangatho 75-85 uvame ukuthola i-TIFF 60-80% encane kune-JPG ngaphandle koshintsho olubonakalayo emgwaqweni wokubuka ojwayelekile. I-lossless TIFF (PNG, TIFF), cabanga ukulondoloza okuncane - ngokuvamile 5-30% nge-deflate / LZW yokucindezela.

Ingabe amafayela ami JPG afihlakele ngesikhathi sokuguqulwa?

Yebo — amafayela alayishwe phezulu JPG aqhubekelwa emisebenzini ehlukanisiwe futhi asuswa ngaphakathi kwemizuzu. Asikwazi ukufunda, ukugcina isikhathi eside, noma ukuhlanganisa idatha ye-pixel. Ifasitela eligcwele lokugcinwa libhalwe ku /privacy/.

JPG

Amafayela e-JPG asebenzisa ukucindezela okulahlekile okwenzelwe izithombe, okunikeza osayizi abancane bamafayela ngenkathi kugcinwa ikhwalithi yokubuka.

TIFF

Amafayela e-TIFF asekela ukujula kwe-bit ephezulu kanye nokucindezelwa okungenakulahlekelwa, okulungele ukuthwebula izithombe zobungcweti kanye nokuphrinta.
