Uma uzothumela umfanekiso wesisindo esikhulu phezu kwe-intanethi, yibeke ku-intanethi, noma nje ungenayo isikhala esanele sediski ukuyigcina, khona-ke kufanele ukwandise lesi sithombe usebenzisa uhlelo olukhethekile. Lokhu kuzosiza ekunciphiseni kakhulu isisindo sayo, futhi ngenxa yalokho - gcina ithrafikhi noma isikhala kwidiski enzima.
Ake sibone ukuthi singanciphisa kanjani isisindo sezithombe kufomethi ye-JPEG usebenzisa uhlelo oluthandwayo lokuthuthukisa izithombe ze-Cesium. Lolu hlelo lokusebenza alugcini nje ukukhiqiza ukucindezelwa kwesithombe esiphezulu, kodwa linamathuluzi amakhulu okulawula lokhu kwenqubo, kanye nesimo esibonakalayo esikahle futhi enembile.
Landa i-Cesium
Ukungeza isithombe
Ukuze uphule inqubo yokucindezela izithombe ohlelweni lwe-Cesium, okokuqala, udinga ukwengeza isithombe kulolu hlelo lokusebenza. Ukuze wenze lokhu, chofoza inkinobho ehambelana iphaneli eliphezulu.
Manje sikhetha isithombe esiyidingayo. Kumele kuqashelwe ukuthi uhlelo lusekela umsebenzi ngamafomethi wezithombe JPG, JPEG, BMP, TIFF, TIF, PNG, PPM, XBM, XPM.
Isimo sokucindezela
Manje udinga ukulungisa kahle ukucindezelwa kwesithombe, noma ngabe ufuna ukushiya izilungiselelo ezizenzakalelayo. Okokuqala, ukuze kube lula, vula isithombe sokubuka esithombeni esiphelile. Ngakho sizobona ukuthi yisiphi isithombe kuzilungiselelo zamanje ezizovela emva kokusebenza kahle.
Okulandelayo, kufanele sibeke izinga lekhwalithi yesithombe esiphelile. Uma usetha izinga eliphezulu kakhulu lokucindezela, ungase ulahlekelwe ikhwalithi yesithombe. Kodwa, uma ungaqondi ama-nuances, kungcono ukushiya leli nani elizenzakalelayo. Lolu hlelo ngokwayo luzobe lube lukhulu kakhulu.
Okokugcina, kufanele sicacise ifolda lapho inguqulo eqinisekisiwe yesithombe izothunyelwa khona.
Inqubo yokucindezela
Ngemuva kokuthi zonke izilungiselelo zibekwe, ungakwazi ukucindezela izithombe ezikhethiwe ngaphandle kokulahlekelwa ikhwalithi ngokuchofoza okukodwa ku-"Compress!" Inkinobho. Uma isithombe esisodwa sithuthukisiwe, inqubo yokucindezela iyenzeka cishe ngaso leso sikhathi, kodwa uma wenza ukuguqulwa kwe-batch, lokhu kungathatha isikhathi.
Uma kuqedile le nqubo, iwindi lizovela, libonisa ukuphela kwenqubo yokucindezela. Iphinde ibonise inani lamafayela aguqulwe ngempumelelo, nenombolo yamaphutha, uma ikhona. Ibuye inikeze ulwazi ngesikhathi esithathwe yinkambiso kanye nokusindisa isikhala esiphethwe ifayela eliguqulwe.
Bheka futhi: izinhlelo zokucindezela isithombe
Njengoba ubona, usebenzisa uhlelo lwe-Cesium, kulula kakhulu ukucindezela isithombe sokuposa, ukuthumela ku-intanethi noma ukuyigcina kwimithombo yefu.
