IDiffPDF isetyenziselwa ukuthelekisa iifayile ezimbini zePDF.

Ngokungagqibekanga uthelekiso lunamagama akwipere nganye yamaphepha, kodwa ukuthelekisa unobumba ngonobumba kuyaxhaswa (umzekelo, kwiilwimi zelogographic). Kwaye kukho nenkxaso yokuthelekisa amaphepha ngenkangeleko (umzekelo, ukuba umzobo utshintshiwe okanye ukuba umhlathi uhlaziywe, okanye ifonti itshintshiwe). Kukwanokwenzeka ukuthelekisa amaphepha athile okanye uluhlu lwamaphepha. Umzekelo, ukuba kukho iinguqulelo ezimbini zefayile yePDF, enye inamaphepha 1-12 kwaye enye inamaphepha 1-13 ngenxa yephepha elongezelelweyo eliye longezwa njengephepha lesi-4, zinokuthelekiswa ngokuchaza uluhlu lwamaphepha amabini, 1-12 kweyokuqala kunye ne-1-3, 5-13 kweyesibini. Oku kuya kwenza iDiffPDF ithelekise amaphepha kwizibini (1, 1), (2, 2), (3, 3), (4, 5), (5, 6), njalo njalo, ukuya (12, 13).

Imizekelo embalwa yeefayile zePDF zinikezelwe kwi-intanethi ukuze ukwazi ukuyizama. Iifayile zePDF zinokulayishwa kwi-GUI (ngokucinezela iFayile #1 kunye neFayile #2 amaqhosha), okanye ngokuzichaza kumgca womyalelo. Ulwazi oluninzi luyafumaneka kwiingcebiso zenkqubo kunye nebhokisi malunga.
