JPEG ukuba JFIF Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

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

Ingaba umbala wam we-CMYK uya kuqhubeka nokuguqulwa kwi JFIF?

Iguqulwe kwi sRGB, kuba JFIF ayinayo i CMYK indlela. Ukusetyenziswa kwesikrini oku kulungile. Ushicilelo lweshishini akusebenzi - utshintsho lwegama lokutshintsha indlela imibala ethambileyo ephindayo kwiqhosha, ngoko thumela umshicileli okuqala JPEG endaweni ye JFIF. Uluhlu lwe.jfif luzalisa iiWindows kunye nezixhobo ezininzi ze web ezisebenzisayo ukuyeka ifayile, ekufuneka ikhoyo kuphela ngenxa yokuba umntu uguqula.

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

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

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

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

Ingaba i JFIF 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. Iifayili ezilayishwe phezulu ze-JPEG 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/.

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

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