JFIF ukuba JPEG Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayili yakho ye JFIF, emva koko umguquli wethu ufaka ukuphuculwa komgangatho owaziyo wefomati ye-JPEG imveliso. Kwifomati ezingalahlekiyo (PNG, TIFF, BMP) sigcina zonke ii-pixels; kwifomati ezilahlekiyo (JPG, WebP) ungalungisa isizathu somgangatho phambi kokukhuphela.

Ingaba uguqulelo JFIF ukuya ku JPEG 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 JPEG.

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

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

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

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

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

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

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

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

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

Ndingayisebenzisa ifayili eguqulweyo JPEG ngemali?

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