JPG ukuba PSD Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-JPG ibe yi-PSD ngaphandle kokulahlekelwa umgangatho womfanekiso?

Layisha phezulu ifayili yakho ye JPG kwaye umguquli usebenzise ukuphuculwa komgangatho owaziyo ifomati ye PSD.

I-JPG ilahlekile: umfanekiso uguqulwa nge-DCT, i-quantized, kunye ne-entropiya-ekhowudiweyo, ngeqhosha lomgangatho elilawula ukuba kuphi okuninzi okulahlekileyo. I-PSD igcina amanqanaba, izigqubuthelo, iindlela zokudibanisa, izinto ezizimeleyo, amanqanaba olungiso nombhalo ohlelayo njengezinto eziphilayo ezihlukileyo.

Phumeza /susa indawo yangasemva/ emva koko ukucima isiqalo — ngoko i-alpha isiqhagamshelanisi PSD ibonelela ngento yokugcinwa. I-PSD igcina yonke intlawulo yokulungisa ebuyiselweyo, nto leyo eyenza ukuba ibe yifomati yomphathi woyilo lwemisebenzi eza kuvavanywa.

Hayi. Ii-artefacts zokucinezela eziphekwe kwi JPG zii-pixels zedata eziqhelekileyo ngoku, kwaye PSD igcina kakuhle kunokuba isuse. Ifayile ihlala ikhula, ngamanye amaxesha ikhula amaxesha amaninzi. Kubalulekile ukwenza phambi kohlela, kuba utshintsho oluthe kratya aluyi kunyusa udidi lwesibini lolahleko phezulu. I-JPG ayinakubonakaliswa ngokucacileyo, ikhupha ngaphezulu xa igcinwa kwakhona, kwaye ivelisa ukutshixa okubonakalayo kumbala othambileyo nombhalo oqaqambileyo.

JPG

Iifayili ze-JPG zisebenzisa ukucinezela okulahlekileyo okulungelelanisiweyo kwiimifanekiso, kunike ubungakanani befayili encinci ngelixa kugcinwa isisombululo esibonakalayo.

PSD
