LEADTOOLS Versie 19 is gereleasd!

Wij zijn blij dat wij mogen aankondigen dat LEADTOOLS Versie 19 gelanceerd is. Belangrijkste onderwerpen in deze release zijn de nieuwe Document Viewer en Document Converter frameworks voor .NET en HTML5/JavaScript. Gecombineerd met significante updates en toevoegingen door de gehele produktlijn van Document, Medical, Imaging en Multimedia SDK's kunnen developers veel meer bereiken dan voorgaande versies met LEADTOOLS V19. Nieuw zijn ook de SDK's specifiek voor PDF imaging of Barcode imaging. Met deze drie nieuwe SDK's wordt het nog laagdrempeliger om LEADTOOLS in uw applicatie ontwikkeling op te nemen.

Deze nieuwe versie heeft de meest uitgebreide feature lijst tot op heden en teveel om allemaal te belichten. We hebben hieronder een overzicht gemaakt van de nieuwe features. Klik op de links om meer te weten te komen van LEADTOOLS V19 SDK's.
