I-Mac Magic: Ukuguqula i-JPEG ibe yi-JPG Yenziwe Yalula!
Ingabe uyagula ukuzwa lezo “E†kanye “G†ezengeziwe ku-JPEG? Ufisa sengathi ngabe bekukhona inguqulo emfushane ne-sassier? Hhayi-ke, ungesabi, ngoba i-JPG ilapha ukusindisa usuku! Nakuba lawa mafomethi amabili amafayela evame ukusetshenziswa ngokushintshana, kukhona umehluko wezobuchwepheshe phakathi kwawo. Kuleli phepha, sizohlola ukufana nomehluko phakathi kwe-JPEG ne-JPG, futhi sinikeze imiyalelo yesinyathelo ngesinyathelo sendlela yokuguqula i-JPEG iye ku-JPG ku-Mac.
1. Ukuqonda i-JPEG ne-JPG: Ukufana Nomehluko
I-JPEG (Joint Photographic Experts Group) kanye ne-JPG womabili amafomethi efayela ezithombe asetshenziswa kakhulu ukugcina nokwabelana ngezithombe zedijithali. Zivame ukusetshenziswa ngokushintshana, kodwa zinomehluko othile wezobuchwepheshe.
I-JPEG
I-JPEG ifomethi yesithombe evame ukusetshenziswa esebenzisa ukucindezela okulahlekile, okusho ukuthi yehlisa usayizi wefayela ngokulahla ngokukhetha idatha ethile yesithombe. Iklanyelwe ukugcina kahle izithombe zezithombe ezinokuhlukahluka kombala okuyinkimbinkimbi kanye nama-gradient abushelelezi. Amafayela e-JPEG asebenzisa isandiso sefayela elithi .jpeg noma .jpg. Ifomethi inika amandla ububanzi obubanzi bokujula kombala futhi isekelwa kabanzi kuwo wonke amadivayisi ahlukene nezinhlelo zokusebenza zesofthiwe. Ukucindezelwa kwe-JPEG kuvumela ukuncishiswa kosayizi wefayela okubalulekile kuyilapho kugcinwa ikhwalithi yesithombe eyamukelekayo, kuyenza ilungele amakhasi ewebhu, ukwabelana nge-inthanethi, nokuthwebula izithombe zedijithali.
I-JPG
I-JPG isandiso sefayela esimele Iqembu Lochwepheshe Bezithombe Ezihlangene, ngokufanayo ne-JPEG. Umehluko oyinhloko phakathi kwe-JPEG ne-JPG usesandisweni sefayela ngokwaso. I-JPG inguqulo efushanisiwe ye-JPEG futhi yamukelwa ukuze ihambisane nomkhawulo wesandiso wefayela onezinhlamvu ezintathu kwamanye amasistimu wokusebenza. Ngobuchwepheshe, awukho umehluko mayelana nokuqukethwe kwesithombe noma ukucindezelwa phakathi kwamafomethi amabili. Bobabili basebenzisa i-algorithm efanayo yokucindezela ukulahleka ukuze banciphise usayizi wefayela kuyilapho belondoloza ikhwalithi yesithombe.
Kafushane, amagama athi JPEG kanye ne-JPG abhekisela kufomethi yefayela yesithombe efanayo, kanti eyakamuva iyinguqulo efushanisiwe yangaphambili. Umehluko kuphela phakathi kwazo isandiso sefayela esisetshenzisiwe, i-JPEG inesandiso esinezinhlamvu ezine kanye ne-JPG enamathela kumkhawulo wezinhlamvu ezintathu.
2. Izindlela zokuguqula i-JPEG ibe yi-JPG ku-Mac
Indlela 1: Ukusebenzisa ukubuka kuqala
Enye indlela eqondile yokuguqula ifayela le-JPEG libe yi-JPG ku-Mac ukusebenzisa uhlelo olwakhelwe ngaphakathi olubizwa ngokuthi Buka kuqala. Landela lezi zinyathelo:
Vula ifayela le-JPEG ekuhloleni kuqala ngokuchofoza kabili kulo.
Ukuze uvule ifayela, khetha “Fayela†kumenyu engaphezulu esikrinini.
Khetha “Thekelisa†kumenyu yokudonsela phansi.
Efasiteleni lokuthekelisa, khetha “JPEG†njengefomethi.
Ongakukhetha, lungisa izilungiselelo zekhwalithi ngendlela oyithandayo.
Yisho ifolda ofisa ukulondoloza kuyo ifayela eliguquliwe.
Isinyathelo sokugcina ukuchofoza “Londoloza†ukuze ulondoloze isithombe ngefomethi ye-JPG endaweni oyikhethayo.
Indlela yesi-2: Ukusebenzisa i-Online Converter
Ukuguqula amafayela akho e-JPEG abe ifomethi ye-JPG ku-Mac kungenziwa kusetshenziswa ithuluzi lokuguqula eliku-inthanethi. Landela lezi zinyathelo ezingezansi:
ISINYATHELO 1: Layisha amafayela e-JPEG
Ukufinyelela iwebhusayithi ye-Convertio ku-Mac yakho, vula isiphequluli sakho sewebhu osithandayo bese uya lapha.
Ekhasini lewebhusayithi, khetha inketho yokulayisha amafayela.
Khetha ifayela(amafayela) le-JPEG ofuna ukuliguqula lisuka kukhompuyutha yakho, i-Google Drayivu, iDropbox, noma unikeze i-URL.
Kungenjalo, ungavele uhudule bese uphonsa ifayela(ama) JPEG ekhasini.
ISINYATHELO 2: Khetha okuthi “kuya ku-JPGâ€
Uma ifayela(amafayela) le-JPEG selilayishiwe, uzocelwa ukuthi ukhethe ifomethi oyifunayo.
Khetha “JPG†njengefomethi yezinketho ezitholakalayo.
I-Convertio isekela amafomethi angaphezu kuka-200, ngakho-ke zizwe ukhululekile ukuhlola amanye amafomethi uma kudingeka.
ISINYATHELO 3: Landa i-JPG yakho
Ngemva kokukhetha “JPG†njengefomethi yokuphumayo, qalisa inqubo yokuguqula.
Vumela isikhathi esithile ukuze ukuguqulwa kwefayela kuqede.
Uma ukuguqulwa sekuqediwe, uzonikezwa isixhumanisi sokulanda sefayela le-JPG eliguquliwe.
Chofoza isixhumanisi sokulanda ukuze ulondoloze ifayela le-JPG ku-Mac yakho.
Ngokusebenzisa isiguquli esiku-inthanethi se-Convertio, ukuguqula amafayela akho e-JPEG abe yifomethi ye-JPG kulula njengokulandela lezi zinyathelo. Jabulela ukuguquguquka nokuba lula kwalesi sixazululo esisekelwe kuwebhu ngezidingo zakho zokuguqulwa kwesithombe.
Indlela yesi-3: Ukusebenzisa i-Graphic Conversion Software
Kubasebenzisi abakhetha izinketho ezithuthuke kakhulu nezici, isofthiwe yokuguqulwa kwezithombe njenge Wondershare UniConverter ingasetshenziswa ukuguqula i-JPEG ibe yi-JPG ku-Mac. Izinyathelo ezingezansi zibonisa inqubo usebenzisa Wondershare UniConverter:
Isinyathelo 1: Hola Wondershare Image Converter
Landa, ufake, futhi uqalise Wondershare Image Converter kusistimu yakho.
Kusukela esigabeni sebhokisi lamathuluzi, khetha inketho yokuguqula isithombe.
Isinyathelo sesi-2: Engeza izithombe zeqoqo
Chofoza uphawu + noma isithonjana esithi Engeza Amafayela ukuze ungenise izithombe zenqwaba.
Phequlula bese ukhetha izithombe ofuna ukuziguqula.
Isinyathelo sesi-3: Hlela amafayela (uma kudingeka)
Nqampuna isithombe, engeza imiphumela, noma sebenzisa ama-watermark usebenzisa izithonjana ezingezansi kwesithombe esincane.
Lungisa usayizi wefayela ngalinye uma kudingeka.
Isinyathelo sesi-4: Khetha ifomethi eqondiwe nosayizi wefayela
Khetha ifomethi oyifunayo kumenyu eyehlayo kokuthi Guqula zonke izithombe zibe:
Sebenzisa isithonjana sezilungiselelo ukuze ulungise usayizi wamafayela angeziwe.
Isinyathelo sesi-5: Iqoqo guqula izithombe
Cacisa indawo yefayela kudeskithophu yakho lapho amafayela aguquliwe azogcinwa khona.
Chofoza inkinobho ethi Guqula ekhoneni elingezansi kwesokudla ukuze uqale inqubo yokuguqula inqwaba.
3. Amathiphu Nokucatshangelwa
Ngaphambi kokuqhubeka nokuguqulwa, cabangela amathiphu nokucabangela okulandelayo:
Yenza isipele ifayela lokuqala le-JPEG ngaphambi kokuguqulwa ukuze uqinisekise ukuthi unekhophi yefayela lokuqala.
Qaphela ukugcina ikhwalithi yesithombe oyifunayo kanye nokulungiswa ngesikhathi senqubo yokuguqula. Lungisa izilungiselelo ngokufanele ukuze ugweme noma yikuphi ukulahlekelwa ngekhwalithi.
Uma usebenzisa amathuluzi okuguqula ku-inthanethi, qaphela futhi ukhethe izinkundla ezithembekile nezivikelekile ukuze uqinisekise ubumfihlo nokuvikeleka kwamafayela akho.
Uma izindlela ezinikeziwe zingahlangabezani nezidingo zakho ezithile noma okuncamelayo, hlola ezinye izinketho zesofthiwe yokuguqulwa kwezithombe ezitholakala kungxenyekazi ye-Mac.
4. Isiphetho
Kusukela ku-JPEG kuya ku-JPG, kufana nekhodi eyimfihlo yokuguqulwa kwesithombe sedijithali ku-Mac yakho. Nge-hocus pocus encane namanye amaqhinga obuchwepheshe, manje usungakwazi ukuvalelisa kulezo “E†kanye “G†ezengeziwe futhi wamukele ifomethi ye-JPG emfushane nesasi. Kungakhathaliseki ukuthi ukhetha okuthi Hlola kuqala, iziguquli eziku-inthanethi, noma udedele isilekeleli sesithombe sangaphakathi, amandla okuguqula asezandleni zakho.
