Yintoni umahluko phakathi kwe-baseline kunye ne-progressive JPEG?

I-Baseline JPEG ilayisha ukusuka phezulu ukuya ezantsi. I-Progressive JPEG ilayisha kwiipasi, ibonisa imbonakalo efiphele kuqala. Iifayile eziqhubekekayo zinkulu kancinci kodwa zibonelela ngesantya sokulayisha esibonakalayo esingcono.

Ukuthatha isampuli ye-chroma kuyichaphazela njani umgangatho womfanekiso?

I-4:4:4 igcina ulwazi olupheleleyo lombala ukuze lube semgangathweni ophezulu. I-4:2:2 kunye ne-4:2:0 zinciphisa idatha yombala kwiifayile ezincinci. Sebenzisa i-4:4:4 kwimifanekiso enemiphetho ebukhali, i-4:2:0 kwimifanekiso.

Ngowuphi umbala weprofayili endifanele ndiwusebenzise xa ndiprinta?

Sebenzisa i-Adobe RGB okanye i-CMYK ukuze uprinte ngobuchwephesha. I-sRGB isemgangathweni wokubonisa iwebhu kunye nesikrini. I-JPEG. ukugcina okanye ukuguqula iiprofayili zombala ngexesha lokuguqulwa.

Ndingawunciphisa njani ubungakanani befayile yeJPEG ngaphandle kokulahleka komgangatho okubonakalayo?

Useto lomgangatho 75-85 lubonelela ngoxinzelelo oluhle kakhulu olunomahluko omncinci obonakalayo. Susa i-metadata engafunekiyo, sebenzisa i-subsampling ye-4:2:0, kwaye uvumele ukwenziwa ngcono ukuze kuncitshiswe kakhulu.
