Iqiniso Ngamafayela Ye-JPEG
Ngokuqhuma kwama-scanner, amakhamera edijithali neWorld Wide Web, ukufometha kwefomethi ye-JPEG kusheshayo kube yindlela esetshenzisiwe kakhulu yesithombe sedijithali. Kubuye kube nokungaqondi kahle kakhulu. Nasi iqoqo leminye imibono engavamile kanye namaqiniso mayelana nezithombe ze-JPEG.
I-JPEG yiSelpelling Proper: Iqiniso
Nakuba amafayela avame ukuphela ku-JPG ye-letter-three extension, noma i-JP2 ye-JPEG 2000, ifomethi yefayela ifakwe i-JPEG. Kuyisigcawu seqembu le-Joint Photographic Experts Group, inhlangano eyenza ifomethi.
I-JPEGs Phonsa Ikhwalithi Njalo Isikhathi Bavuliwe futhi / noma Basindisiwe: Amanga
Ukuvula nje noma ukubonisa isithombe se-JPEG akulimazi nganoma iyiphi indlela. Ukulondoloza isithombe ngokuphindaphindiwe phakathi neseshini yokuhlela efanayo ngaphandle kokuvala isithombe ngeke kuqoqe ukulahlekelwa ngekhwalithi. Ukukopisha nokwakha kabusha i-JPEG ngeke kuveze noma yikuphi ukulahlekelwa, kodwa abanye abahleli bezithombe bavuselela i-JPEG uma umyalo "Gcina njengo" usetshenziswa. Phinda uphinde uphinde usebenzise ama-JPEG kumphathi wefayela esikhundleni sokusebenzisa i- "Londoloza njenge-JPEG" ohlelweni lokuhlela ukugwema ukulahlekelwa okwengeziwe.
I-JPEGs Phonsa Ikhwalithi Njalo Isikhathi Bavuliwe, Bahlelwe Futhi Basindiswa: Kuyiqiniso
Uma isithombe se-JPEG sivulwa, sihlelwe futhi sigcinwa futhi siphumela ekuqedeni kwesithombe esengeziwe. Kubaluleke kakhulu ukunciphisa inani lezinhlelo zokuhlela phakathi kokuqala kokuqala kwesithombe se-JPEG. Uma kufanele wenze imisebenzi yokuhlela ngezikhathi eziningana noma ezinhlelweni eziningana, kufanele usebenzise ifomethi yesithombe engalahleki, njenge-TIFF, BMP noma i-PNG, ngezikhathi zokuhlela eziphakathi ngaphambi kokulondoloza inguqulo yokugcina. Ukulondoloza okuphindaphindiwe phakathi neseshini yokuhlela efanayo ngeke ulethe umonakalo owengeziwe. Kwenzeka kuphela lapho isithombe sivaliwe, sivuliwe kabusha, sihleliwe futhi sigcinwa futhi.
I-JPEGs Phonsa Ikhwalithi Njalo Isikhathi Bona & # 39; Besebenze Kuhlelo Lokuhlelwa Kwekhasi: Amanga
Ukusebenzisa isithombe se-JPEG ohlelweni lokuhlelwa kwekhasi alungise isithombe somthombo ngakho akukho mfanelo elahlekile. Noma kunjalo, ungathola ukuthi imibhalo yakho yokuhlela inkulu kakhulu kunamanani amafayela we-JPEG ashumekile ngoba uhlelo ngalunye lwesofthiwe yesakhiwo sekhasi lusebenzisa izinhlobo ezahlukene zokucindezela kumafayela omqulu wabo,
Uma Ngicindezela I-JPEG Ezingamaphesenti angu-70 Kamuva Iphinde uyivule futhi uyiqede Ngamaphesenti angu-90, I-Final Image izobuyiselwa ku-Quality Quality Set 90 Percent: Amanga
Ukugcina kokugcina ngamaphesenti angu-70 kuveza ukulahlekelwa okungapheli kwikhwalithi engakwazi ukubuyiselwa. Ukulondoloza futhi ngamaphesenti angu-90 kuphela kungenisa ukuchithwa okungeziwe kwesithombe esivele selahlekelwe kakhulu ngekhwalithi. Uma kufanele udidekisile futhi uvuselele isithombe se-JPEG, ukusetha izinga elifanayo isikhathi ngasinye kubonakala sengathi ukuletha ukungcola okuncane noma okungekho ezindaweni ezingasetshenziswanga zesithombe.
Isimiso esifanayo sokubeka esichazwe nje asisebenzi uma ugwaza i-JPEG, noma kunjalo. Ukucindezela kusetshenziselwa amabhlogo amancane, okwenziwe ukuphakama okungama-8 noma angu-16-pixel. Uma utshala i-JPEG, isithombe sonke sishintsha ukuze amabhlokhi angahambisani ezindaweni ezifanayo. Isofthiwe ethile inikeza isici sokuhlunga okungenakulahlekelwa kwe-JPEGs, njenge-freeware JPEGCrops .
Ukukhetha i-Same Numeric Ukuhlelwa Kwekhwalithi Ye-Jpegs Kulondolozwe Kuhlelo Olulodwa Luzonikeza Imiphumela Efanayo Njengoba I-Quality efanayo Yokubeka I-Quality In Enye Uhlelo: Amanga
Izilungiselelo zekhwalithi akuzona ezijwayelekile kuzo zonke izinhlelo ze- software zehluzo . Ukuhlelwa kwekhwalithi ye-75 ohlelweni olulodwa kungabangela isithombe esincane kakhulu kunesithombe esifanayo esilondoloziwe ngesilungiselelo semfanelo se-75 kolunye uhlelo. Kubalulekile futhi ukwazi ukuthi isofthiwe yakho iyini uma ubeka ikhwalithi. Ezinye izinhlelo zinenani elilinganiselwe nekhwalithi phezulu kwesilinganiso ukuze ukukala kwe-100 kuyikhwalithi ephezulu kakhulu ngokuncintisana okuncane. Ezinye izinhlelo zisekela izinga lokucindezela lapho ukuhlelwa kwezingu-100 kuyikhwalithi ephansi kakhulu nokucindezela okuphezulu. Amanye ama-software namakhamera adijithali asebenzisa amagama aso njengama-low, aphakathi naphezulu aphezulu kwezilungiselelo zekhwalithi. Bona izithombe-skrini ze-JPEG ukonga izinketho ezinhlelweni ezihlukahlukene zesofthiwe yokuhlela isithombe.
Ukubekwa Kwemfanelo Kwezingu-100 Akudabuki Isifanekiso Konke: Amanga
Ukulondoloza isithombe kwifomethi ye-JPEG njalo kuveza ukulahlekelwa kwekhwalithi, nakuba ukulahlekelwa ekuhlelweni kwekhwalithi ye-100 kungabonakali ngeso lengqondo eliphansi. Ukwengeza, ukusebenzisa ukulungiswa kwekhwalithi ye-100 kuqhathaniswa nokuhlelwa kwekhwalithi ye-90 kuya kwezingu-95 noma kanjalo kuyoholela ekubeni usayizi wefayili ophakeme kakhulu ngokuya kwezinga lokulahlekelwa kwesithombe. Uma isofthiwe yakho inganikezi ukubuka kuqala, zama ukulondoloza amakhophi amaningana wesithombe ngo-90, 95, no-100 ikhwalithi bese uqhathanisa usayizi wefayela nomgangatho wesithombe. Amathuba angeke abe khona umehluko wokuhlukanisa phakathi komfanekiso we-90 no-100, kodwa umehluko usayizi ungabonakala. Khumbula ukuthi ukuguqulwa kombala okucashile kungumphumela owodwa wokucindezela kwe-JPEG - ngisho nasezilungiselelweni eziphezulu - ngakho-ke i-JPEG kufanele igwenywe ezimweni lapho kubonakala khona ukufanisa kombala okuqondile.
I-Jpegs Ehamba phambili Iphuthuma Ngokushesha Kune-Jpegs Ejwayelekile: Amanga
I-JPEG eqhubekayo ibonisa kancane kancane njengoba iyalanda ukuze ivele iqale ngekhwalithi ephansi kakhulu futhi kancane kancane icacile kuze kube yilapho isithombe sesilandiwe ngokugcwele. I-JPEG eqhubekayo inkulu ngobukhulu befayela futhi idinga amandla amaningi okucubungula ukuze ahlaziye futhi abonise. Futhi, isofthiwe ethile ayinakukwazi ukubonisa i-JPEG eqhubekayo - iningi ikakhulukazi uhlelo lokucabanga lwamahhala oluhlanganiswe nezinguqulo ezindala ze-Windows.
I-Jpegs idinga Ukucubungula Ngaphezulu Amandla Ukubonisa: Kuyiqiniso
I-JPEG akumele ilandwe kuphela kodwa ihlelwe kabusha. Uma ngabe uqhathanisa isikhathi sokubonisa se-GIF ne-JPEG enosayizi wefayela elifanayo, i-GIF izoboniswa ngokukhawuleza kune-JPEG ngoba uhlelo lwayo lokucindezela aludingi amandla amaningi okucubungula ukuze ahlaziye. Lokhu ukubambezeleka okuncane akucaci lutho ngaphandle kwalezi zinhlelo ezihamba kancane kakhulu.
I-JPEG Yifomethi Yonke Injongo Efanelekayo Ngayo Noma Yimuphi Umfanekiso: Amanga
I-JPEG ifaneleka kakhulu emifanekisweni emikhulu yezithombe lapho usayizi wefayela kubaluleke kakhulu, njengezithombe ezizothunyelwa kuwebhu noma ezithunyelwa nge-imeyili naku-FTP. I-JPEG ayifanele imifanekiso eminingi encane ngaphansi kwamaphikseli angamakhulu ambalwa, futhi ayifanele ama-skrini, izithombe ezinombhalo, izithombe ezinemigqa ebukhali kanye namabhuloki amakhulu ombala, noma izithombe ezizohlelwa ngokuphindaphindiwe.
I-JPEG Inhle Ngempela Yesikhathi Esiyisikhathi Isithombe Sezinqolobane: Amanga
I-JPEG kufanele isetshenziselwe kuphela ukugcinwa kokugcinwa kwe-archival lapho isikhala sediski siqala ukucabangela. Ngenxa yokuthi izithombe ze-JPEG zilahlekelwa ikhwalithi njalo uma zivuliwe, zihleliwe futhi zilondoloziwe, kufanele zigwenywe ezimweni zokugcina lapho izithombe zidinga ukucubungula okuqhubekayo. Njalo gcina ikhophi yenkosi engalahleki yimuphi umfanekiso olindele ukuyihlela futhi esikhathini esizayo.
Izithombe ze-JPEG Don & # 39; t Ukusekela ukucaca: Kuyiqiniso
Ungase ucabange ukuthi ubone ama-JPEG ngokuvuleka kuWebhu, kodwa isithombe senziwe empeleni esihlosiwe esihlosiwe esifakwe esithombeni ngendlela ebonakala singagxiliwe ekhasini leWebhu ngesizinda esifanayo. Lokhu kusebenza kahle uma isizinda singukuthungwa okucashile lapho izingqimba zingabonakali khona. Ngenxa yokuthi i-JPEG incike ekushintsheni kombala othile, noma kunjalo, ukugqama kungase kungabonakali kukhululekile kwezinye izimo.
I Can Save Space Disk Ngokuguqula Izithombe Zami ze-GIF Ku-Jpegs: Amanga
Izithombe ze-GIF sezivele zinciphise zaba imibala engu-256 noma ngaphansi. Izithombe ze-JPEG zilungile ngemifanekiso emikhulu yezithombe enezigidi zembala. Ama-GIF afaneleka izithombe ezinemigqa ebukhali nezindawo ezinkulu zombala owodwa. Ukuguqula isithombe esijwayelekile se-GIF ku-JPEG kuzoholela ekushintsheni kombala, ukufiphaza nokulahlekelwa ngekhwalithi. Ifayili elandelwayo iyoba yikhulu kakhulu. Ngokuvamile akuyona inzuzo yokuguqula i-GIF kuya ku-JPEG uma isithombe sokuqala se-GIF singaphezu kuka-100 Kb. I-PNG ingcono kakhulu.
Zonke izithombe ze-JPEG ziyisinqumo esiphakeme, ama-Quality-Quality Photos: Amanga
Ikhwalithi yokuphrinta inqunywa ubukhulu bephikseli yesithombe. Isithombe kufanele okungenani sibe nama-pixels angu-480 x 720 ngokuprinta kwekhwalithi ejwayelekile yesithombe esingu-4 "x 6". Kumelwe kube nama-pixels angu-960 x 1440 noma ngaphezulu kokuprinta okuphezulu kuya phezulu. I-JPEG ivame ukusetshenziselwa izithombe ukuthi zihanjiswe futhi ziboniswe ngeWebhu, ngakho lezi zithombe ngokuvamile ziyancishiswa ukulungiswa kwesikrini futhi aziqukethe idatha eyanele yephikseli ukuze uthole ukuphrinta okusezingeni eliphezulu. Ungathanda ukusebenzisa isilungiselelo sokucindezela izinga eliphezulu lekhamera yakho uma ulondoloza i-JPEG kusuka kukhamera yakho yedijithali ukuze unciphise umonakalo obangelwa ukucindezelwa. Ngibhekisela ekulungisekeni kwekhwalithi yekhamera yakho, hhayi ukuxazulula ukuthi imiphumela yephikseli ingakanani. Akuwona wonke amakhamera wedijithali enikeza le nketho.
