DiffPDF waxaa loo isticmaalaa in lagu barbardhigo laba faylal oo PDF ah.

Sida caadiga ah isbarbardhigga waa ereyada ku yaal labada bog ee kasta, laakiin isbarbardhigga jile ahaan sidoo kale waa la taageerayaa (tusaale ahaan, luqadaha logographic). Waxa kale oo jirta taageero lagu barbar dhigo boggaga muuqaal ahaan (tusaale ahaan, haddii jaantuska la beddelo ama haddii cutubka dib loo habeeyo, ama farta la beddelo). Waxa kale oo suurtogal ah in la is barbar dhigo bogag gaar ah ama kala duwanaanta bogga. Tusaale ahaan, haddii ay jiraan laba nooc oo faylka PDF ah, mid leh bogagga 1-12 iyo kan kale ee leh bogagga 1-13 sababta oo ah bogga dheeraadka ah ee lagu daray bogga 4, waxaa la barbar dhigi karaa iyadoo la tilmaamayo laba bog oo kala duwan, 1-12 kan koowaad iyo 1-3, 5-13 kan labaad. Tani waxay DiffPDF ka dhigi doontaa isbarbardhigga boggaga lammaanaha (1, 1), (2, 2), (3, 3), (4, 5), (5, 6), iyo wixii la mid ah, ilaa (12, 13).

Dhowr tusaale oo faylasha PDF ah ayaa lagu bixiyaa onlayn si aad isku daydo. Faylasha PDF waxaa laga soo rari karaa GUI (adigoo riixaya File #1 iyo File #2 badhamada), ama adoo ku cadaynaya khadka taliska. Macluumaad dheeraad ah ayaa laga helayaa agabka barnaamijka iyo sanduuqa ku saabsan.
