Indlela yokuguqula JPEG ukuba TIFF

Inyathelo 1: Rhweba ngaphakathi JPEG iifayili usebenzisa iqhosha phezulu okanye nge shift nendawo.

Inyathelo 2: Nqakraza kwiqhosha 'Uguqulo' ukuqala uguqulo.

Inyathelo 3: Gcina ifayile yakho eguqulweyo TIFF iifayile

JPEG ukuba TIFF Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayili yakho ye JPEG, emva koko umguquli wethu ufaka ukuphuculwa komgangatho owaziyo wefomati ye-TIFF imveliso. Kwifomati ezingalahlekiyo (PNG, TIFF, BMP) sigcina zonke ii-pixels; kwifomati ezilahlekiyo (JPG, WebP) ungalungisa isizathu somgangatho phambi kokukhuphela. I-JPEG ifana ne-JPG ne-JFIF — uluhlu oluneleta ezine luye lwaqala, kwaye oluneleta ezintathu lukhona kuphela ngenxa ye-DOS 8. 3 umda wegama lefayili.

Ingaba uguqulelo JPEG ukuya ku TIFF lugcina ukubonakala ngaphaya?

Ukubonakala ngaphaya kuqhubeka xa usiya kwi-PNG, WebP, TIFF, GIF okanye SVG. Ukutshintsha kwi-JPG kugubungela isiqhagamshelanisi se-alpha phantsi kwesiqalo esimhlophe - ukuba ufuna ukubonakala ngaphaya, cwangcisa ifomati eyaziyo ukubonakala ngaphaya endaweni ye TIFF.

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

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

Ndingaguqula izigidi zeefayili JPEG zibe TIFF 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-TIFF iya kuba nesisombululo esinjani na?

Ukuziphatha okungagqibekanga kuku 1:1 — i TIFF yakho yemveliso ineempawu ezifanayo ze-pixels njengemvelaphi JPEG. Ukuba ufuna ukuguqula ubungakanani njengenxalenye yokuguqula, sebenzisa i /resize-image/ isixhobo emva kokuguqula, okanye uyibeke kwi- /image-resize/ utility.

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

Kwi-JPG / WebP, umgangatho we-75-85 ufumana ifayili i-60-80% incinane kune-JPEG 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 JPEG zifihlakeleyo ngexesha lokuguqulwa?

Ewe. Iifayile ezilayishwe phezulu ze JPEG ziqhubekekiswa kwiseva yethu yokuguqula, akukho mntu ujonge phezulu, kwaye azisasazwanga. Ukukhuphela kunye nokuguqulwa kwe TIFF kususwa ngokuzenzekelayo malunga neyure ezili-24 emva kokuguqulwa, oshiya ixesha lokulayisha ezantsi iziphumo. Bona /privacy/ kwinkqubo epheleleyo.

Kutheni i-TIFF iguqulwe ibe mkhulu/ncinane kuneleyo ndiyifumeneyo?

Ifayili JPEG enesicitho esinamandla (umzekelo, i-JPG enesicitho esiphezulu) ihlala ikhula xa iphinde ikhowudiwe ibe yi-lossless TIFF (PNG, TIFF), kwaye i-high-bitrate lossless JPEG ihlala ikhula ngokugqithisileyo xa ihamba kwi-JPG/WebP. Uthelekiso luxhomekeke kwizinto eziqulethe umfanekiso (iifoto zicitha ngokuhlukileyo kunemizobo yelayini).

Ndingayisebenzisa ifayili eguqulweyo TIFF ngemali?

Ewe. Uguqulelo lutshintsho lwefomati - ilungelo lokushicilela kwimixholo yomfanekiso lihlala kuwe (okanye umntu ophetheyo kumgca womthombo JPEG). Sidibanisa akukho phawu lwamanzi, akukho phawu lwemetadata, kwaye sicela akukho layisensi ngaphezulu kwemveliso.
