Kwifomati ezingalahlekiyo (PNG, TIFF, BMP) sigcina zonke ii-pixels; kwifomati ezilahlekiyo (JPG, WebP) ungalungisa isizathu somgangatho phambi kokukhuphela. 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 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. I-JPG ilahlekile: umfanekiso uguqulwa nge-DCT, i-quantized, kunye ne-entropiya-ekhowudiweyo, ngeqhosha lomgangatho elilawula ukuba kuphi okuninzi okulahlekileyo.

Yintoni malunga ne-EXIF metadata xa uguqula TIFF ukuya ku JPG?

Kwiziguqulelo ezininzi, iimayile ze-EXIF zekhamera ezinjengemodeli yekhamera kunye nendawo ye-GPS azithunyelwe kwi-JPG. Akukho mmiselo kule phepha ukugcina okanye ukususa i-metadata, ngoko khangela isiphumo ngombonisi we-metadata ukuba kubaluleke.

Ndingaguqula izigidi zeefayili TIFF zibe JPG ngaxeshanye?

Iifayile ezininzi kumsebenzi omnye zifuna inkqubo ehlawulweyo. Ukusetyenziswa okukhululekileyo yifayile enye ngoguqulelo, uguqulelo olunye ngeyure. Kwinkqubo ehlawulweyo ungadibanisa iifayile ezininzi kumsebenzi omnye, emva koko ulayishe impumelelo nganye kwiyo okanye zonke kwi ZIP enye.

Ingaba i-JPG iya kuba nesisombululo esinjani na?

Ukuziphatha okungagqibekanga kuku-1:1 — i-JPG yakho yemveliso inezinto ezilinganayo ze-pixels njenge-TIFF. Sebenzisa /resize-image/ inyathelo elahlukileyo emva kokuguqula ukuba ufuna ukunyusa okanye ukunyusa i-scale njengenxalenye yokuhamba komsebenzi.

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

Kwi-JPG / WebP, umgangatho we-75-85 ufumana ifayili i-60-80% incinane kune-TIFF yomthombo ngaphandle kotshintsho olubonakalayo kumgama wokujonga oqhelekileyo. Kwiinjongo ezingalahlekiyo (PNG, TIFF), lindele ukonga okuncinci — ngokuqhelekileyo 5-30% nge-deflate / LZW yokucinezela engcono.

Ingaba iifayile zam TIFF zifihlakeleyo ngexesha lokuguqulwa?

Ewe. Iifayili ezilayishwe phezulu ze-TIFF ziqhubekekiswa kwiseva yethu yazo kwaye azibonisi okanye zinikezelwe. Iifayile ezilayishwe phezulu kunye nemifanekiso eguqulweyo zicinywa ngokuzenzekelayo malunga neyure ezili-24 emva kokuguqulwa. Inkqubo yobumfihlo epheleleyo ikwi /privacy/.
