6. Iindlela zokucinezela umfanekiso ophuculweyo wokwandisa ubungakanani bokunciphisa

Kule mihla, ukucinezelwa kwemifanekiso kuye kwaba yimfuneko ukwenza ugcino kunye nesantya sokulayisha kwiiwebhusayithi kunye nosetyenziso lweselfowuni. ⁢Kwesi sithuba, siza kuphonononga iindlela eziphucukileyo zoxinzelelo lwemifanekiso ezikuvumela ukuba ukhulise ukunciphisa ubungakanani beefayile zefoto ngaphandle kokuncama umgangatho wazo obonakalayo.

Enye yezona ⁤tekhnikhi ezisebenzayo kusetyenziso lwe-⁢i-algorithms yoxinzelelo olungenalahleko,⁤ njenge-algorithm yoxinzelelo lwefayile ye-PNG. ​ Le algorithm isebenzisa ubuchule bekhowudi obususa ukungafuneki⁢ kunye nokunciphisa ubungakanani bolwazi olungafunekiyo emfanekisweni, ukufumana unciphiso ⁤ubungakanani ngaphandle kokuchaphazela umgangatho womfanekiso wokuqala.. Iqhinga elinye lokuqhubela phambili nokuphucula ucinezelo kukwenza ukulungelelaniswa kwe-post-compression, usebenzisa izixhobo zokuphucula i-PNG ezisusa i-metadata kunye nokusebenzisa iindlela ezongezelelweyo zokunciphisa ubungakanani.

Enye indlela ehambele phambili kukucinezela okusekwe kuguqulo lweWavelet. Le ndlela ibolisa umfanekiso ube ziifrikhwensi ezahlukeneyo kunye ⁣ nezisombululo, ⁤ukuvumela ucinezelo olungcono ngokususa iinkcukacha ezingaqondakaliyo⁤ kwiliso lomntu.. Ifomathi yefayile yeJPEG 2000 yenye yeefomati ezisebenzisa le ndlela kwaye inikezela ngokunciphisa ubungakanani obukhulu ngaphandle kokuncama umgangatho omkhulu. Njengoko kunye ne-algorithm ye-PNG, iindlela zokunyanzeliswa kwe-post-compression zingasetyenziswa ukuphelisa ukukhutshwa okungaphezulu kunye nokuphucula ngakumbi izinga loxinzelelo.

Ekugqibeleni, sinokuthatha inzuzo yefomathi yefayile yeWebP, ephuhliswe nguGoogle. Le fomati isebenzisa indibaniselwano ye-algorithms yokunyanzeliswa kwelahleko kunye nelahleko, evumela ukuncipha kobukhulu obunobundlongondlongo kwimifanekiso eneenkcukacha ezingaphantsi, kodwa ukugcina umgangatho wokubonwa kakuhle kwiindawo ezibaluleke kakhulu.. Ukongeza, iWebP⁢ inikezela ⁤inkxaso yopopayi kunye nokungafihli nto, iyenze ibe ⁤ifomati eguquguqukayo kakhulu yeentlobo ezahlukeneyo zomxholo wewebhu. Nangona kunjalo, kubalulekile ukuqwalasela ukuhambelana⁢ nezikhangeli kunye nezixhobo phambi kokusebenzisa le fomati. Isishwankathelo, obu buchwephesha bokucinezela umfanekiso zizixhobo ezinamandla zokwandisa ubungakanani bokunciphisa ubungakanani, kodwa kubalulekile ukuvavanya ngononophelo umgangatho wokubonwayo ophumayo kunye nokuhambelana neemeko ezahlukeneyo zokusetyenziswa.

7. Iingqwalasela ezibalulekileyo xa unciphisa ubungakanani besithombe sokusetyenziswa kwiiplatifti ezahlukeneyo kunye nezixhobo

Uhlengahlengiso lobungakanani bomfanekiso: Xa kufikwa ekunciphiseni ubungakanani befoto ukuze isetyenziswe kumaqonga kunye nezixhobo ezahlukeneyo, kubalulekile ukugcina iingqwalasela ezininzi ezibalulekileyo engqondweni. Okokuqala, kufuneka ukhethe isoftware efanelekileyo yokuhlela umfanekiso. Kukho iintlobo ngeentlobo zezixhobo ezikhoyo kwi-intanethi ezikuvumela ukuba uguqule ubungakanani beefoto. ngokufanelekileyo kwaye ichanekile. Ukongeza, ifomathi yemifanekiso efanelekileyo kakhulu yeqonga ngalinye kufuneka ithathelwe ingqalelo. Ngokomzekelo, ifomathi yeJPEG isetyenziswa ngokubanzi kwaye ifanelekile kwiwebhu njengoko inika ubudlelwane obuhle phakathi komgangatho kunye nobukhulu befayile. Kwelinye icala, i Ifomathi yePNG Kukhethwa ukuba⁢ imifanekiso engafihliyo kwaye igcina umgangatho ophezulu ngaphandle koxinzelelo olongezelelweyo.

Isisombululo ⁤kunye neepixels: Xa ulungisa ubungakanani befoto, kubalulekile ukuqwalasela isisombululo kunye neepikseli. Isisombululo sibhekisa kwinani leepixels nge-intshi nganye (ppi) kwaye ichaphazela ngokuthe ngqo umgangatho wokugqibela womfanekiso. Ngokuqhelekileyo, isisombululo se-72 ppi sanele kwimifanekiso kwiwebhu, ngelixa ukuprintwa kwekhwalithi ephezulu kunokufuna isisombululo se-300 ppi Ukongeza, xa uhlaziywa imifanekiso, imifanekiso, kubalulekile ukugcina ibhalansi phakathi komgangatho obonakalayo kunye nobukhulu befayile . Ukunciphisa inani elipheleleyo leepixels kunokunceda ukunciphisa ubungakanani bomfanekiso, kodwa kunokuchaphazela kakubi ubukhali kunye neenkcukacha. Ngoko ke, kubalulekile ukufumana i-⁤compromise efanelekileyo ehlangabezana ⁤iimfuno ze-⁤platform kunye nesixhobo ngasinye.

Ukulungiswa komfanekiso: Ukulungiswa komfanekiso yenye into ebalulekileyo xa unciphisa ubungakanani bomfanekiso. Ukunyanzeliswa komfanekiso kunokunceda ukunciphisa indawo yokugcina kunye nokuphucula ixesha lokulayisha kwiphepha lewebhu. Nangona kunjalo, kubalulekile ukufumana ibhalansi phakathi koxinzelelo kunye nomgangatho womfanekiso. Ezinye izixhobo zokuhlela umfanekiso zikuvumela ukuba ulungelelanise umgangatho woxinzelelo ukuze uqinisekise inkangeleko entle ebonakalayo ngaphandle kokunyusa ngokungeyomfuneko ubungakanani befayile. Ukongezelela, kunokwenzeka ukunciphisa ubungakanani bomfanekiso ngokususa idatha engadingekile, njengemethadatha, iileya, okanye iinxalenye zomfanekiso ezingabalulekanga. Isishwankathelo, xa unciphisa ubungakanani besithombe, kubalulekile ukukhetha isoftware efanelekileyo, qwalasela isisombululo kunye neepikseli, kwaye ulungise umfanekiso ukuze ufumane ibhalansi efanelekileyo phakathi komgangatho kunye nobukhulu befayile.
