Ukuvula nokusindisa izithombe ze-Jpeg: Ngabe Ziyazilulaza Ngempela Izithombe Zakho?

Ngiyabonga kuRobert Watcher we phuma futhi URobert Watcher Izithombe zalesi siposi sesivakashi esithakazelisayo ziphendula lo mbuzo, "Ingabe ukuvula nokugcina izithombe ze-jpeg kaninginingi kwehlisa isithunzi sezithombe zakho?"

Sekuyisikhathi eside ngijabule ngesimangalo sokuthi ukuvuselela amafayela wakho wezithombe kuzolulaza isithombe. Noma ushintshe igama lefayela elilula futhi ulondoloze njengeJpeg kuzoba nesizukulwane sokwehliswa isithunzi. Manje angiphikisi ukuthi yilokho okwenzekayo - - - kodwa engikuqaphelile umuzwa wabathwebuli bezithombe abaningi ukuthi abakwazi ukuwugcina njenge-jpeg noma kungenjalo bazogcina benesithombe esingahle sisebenziseke.

Eminyakeni eminingana edlule, ngenza isivivinyo ngokuvula nokugcina kabusha ifayela le-jpeg ngaphandle kokwenza noma yikuphi ukucubungula phakathi, nokugcina futhi ngekhwalithi ephezulu kakhulu. Ngokuphikisana nalokho ebengikholwa kukho (ukuthi ukuvula nokugcina ngisho kanye noma kabili kungaba yingozi), bekungekho ukwehliswa okuphawulekayo kwesithombe ebengisisebenzisa lapho bengingeke ngikwazi ukusebenzisa noma ukubona isithombe noma ukuphrinta ikhwalithi enhle yokuphrinta - ngisho nangemva kokuvula nokugcina kabusha ngikholwa ukuthi bekungamahlandla angama-20 ngaphambi kokuthi ngiqale ukubona ukwehliswa isithunzi okukhulu ikakhulukazi ezindaweni zezulu.

Ngakho-ke isiphetho sami emuva ngaleso sikhathi njengoba kunjalo nanamuhla - ukuthi asidingi ukukhathazeka ngokweqile mayelana nokulondoloza izikhathi ezimbalwa ngekhwalithi ephezulu kakhulu ye-jpeg. Ukuthi kungasindiswa kangakanani kungancika kokuqukethwe kwesithombe nakuhlelo. Ezimweni eziningi noma kunjalo, imvamisa besizobuyela kufayela lesithombe loqobo ukuqhubeka nokwenza izinguquko ezibanzi esikhundleni sokuvula nokucubungula nokugcina njenge-jpeg kaninginingi.

Indlela engikwenza ngayo mathupha ngamafayela wami we-jpeg asuka kwikhamera (efanayo uma ngisebenzise okuluhlaza ngalolo daba) ukugcina amafayela wami wesithombe acutshunguliwe njenge .psd noma .bmp noma enye ifomethi yefayela engalahleki futhi empeleni ayikho inkinga nge ukwehliswa isithunzi njengoba ngiqhubeka nokwenza kabusha futhi ngisindisa. Kepha uma kunesidingo, ngeke nginqikaze ukugcina kabusha njenge-jpeg esezingeni eliphakeme - futhi ngenze kaningi lapho ngigcine khona ifayili elicubunguliwe njenge-jpeg yokuphrinta futhi kamuva ngafuna ukwenza izinto kancane ngaphandle kokuqala okusha.

Ngakho-ke ngicabange ukuthi ngizophinde ngivakashele lolu vivinyo engalwenza eminyakeni eminingi eyedlule - futhi ngathatha isinqumo sokusebenzisa ifayili elivela ku-Olympus E-3 yami elalinezihloko ezinhlobonhlobo - kepha okubalulekile ngangifuna isithombe esizofaka phakathi nohlaza okwesibhakabhaka izindawo zezulu eziwuhlobo lokuqukethwe okukhombisa ukugqashuka kwesithombe kanye nezinto zobuciko zokucindezela kakhulu. Inqubo yami bekuwukuvula ifayili lokuqala le-jpeg bese ngiqamba kabusha ifayili ngenkathi ngilondoloza njengekhwalithi ye-Jpeg “12” bese ngivala ifayili ku-Photoshop. Ngibe sengiphinda ngivula lelo fayela elisanda kulondolozwa futhi ngaqamba kabusha leli fayela ngenkathi ngilondoloza njengekhwalithi yeJpeg “12” ngabe sengilivala lelo fayela ku-Photoshop. Ngiyiphindile le nqubo ye-Open / Save / Close yokwakha inani lezizukulwane.

Lesi isithombe sefayela loqobo:

Futhi lesi yisithombe sesizukulwane se-10 ngemuva kokulondolozwa kabusha njengekhwalithi ye-Jpeg 12 ku-Photoshop:

Ngazo zonke izinhloso ezisebenzayo, noma ngabe kunenani elibi kakhulu lokugcina, isizukulwane se-10th sisengasetshenziselwa iwebhu nokuphrinta, noma kunjalo ngiyangabaza ukuthi noma ngubani uzodinga ukuhlenga izikhathi ezi-3 noma ezi-4 ingasaphathwa eyishumi noma ngaphezulu.

Ngithathe isitshalo esingu-100% kufayela loqobo, ifayili lesizukulwane lesi-5, nefayela lesizukulwane se-10 ukuqhathanisa, futhi ngiligcinele iwebhu ngekhwalithi engu-100% ukwenza ukuqhathanisa kunembe kakhudlwana.

Isitshalo se-pixel esingu-600 × 450 kusuka kufayela loqobo:

Isitshalo se-pixel esingu-600 × 450 kusuka kufayela lesizukulwane sesi-5

Isitshalo se-pixel esingu-600 × 450 kusuka kufayela lesizukulwane sesi-10

Akungabazeki ukuthi izindawo ezisibhakabhaka ezibushelelezi ziqala ukukhombisa imiphumela ye-jpeg compression ngokulondoloza kaninginingi, kepha yizona ezishayeke kakhulu (yingakho ngazifaka esithombeni sami sokuhlola) futhi ngisho naleli fayela kungenzeka libonwe kuphela lapho ubuka i-100% kusiqaphi hhayi lapho uphrinta noma ushintsha usayizi ukuze usetshenziselwe iwebhu (izinhlelo ezivame kakhulu). Ezinye izindawo zesigcawu, zikhombisa okuncane kakhulu uma kukhona okwehlisayo ngisho nangemva kokulondolozwa okuningi. Inhloso yami futhi akusho ukuthi ukulondolozwa kaningi njengefayela le-jpeg kuyinto ekahle yokwenza. Kepha ngokuhlola okuqukethwe kwakho nokusetshenziswa kwakho, kungahle kungabi yinkinga enkulu njengoba abaningi bekwenza - futhi kungahle kube yisikhathi esinqabile lapho kudingeka.
