Tag nrho cov duab hauv JPEG yog Cov Daws Teeb Meem, Cov Ntawv Sau-Sau Npe: Cuav
Sau zoo yog txiav txim siab pixel qhov loj ntawm daim duab. Ib qho duab yuav tsum muaj tsawg kawg yog 480 x 720 pixels rau qhov nruab nrab luam ntawm 4 "x 6" duab. Nws yuav tsum muaj 960 x 1440 pixels los yog ntau dua rau qhov nruab nrab rau high-print. JPEG feem ntau yog siv rau cov duab uas yuav xa tawm thiab tso tawm ntawm lub Web site, yog li cov dluab no feem ntau txo rau kev daws teeb meem thiab tsis muaj cov ntaub ntawv pixel txaus kom tau txais kev luam tawm zoo. Koj tuaj yeem siv koj lub koob yees duab qhov yooj yim dua qhov chaw thaum txuag JPEGs los ntawm koj cov koob yees duab los txo qhov kev puas tsuaj los ntawm compression. Kuv tabtom referring rau qhov zoo ntawm koj lub koob yees duab, tsis muaj kev daws teeb meem uas pixel qhov ntev. Tsis yog txhua lub koob yees duab digital muab qhov kev xaiv no.
