Resize Filter SDK Technology

LEADTOOLS provides developers with the LEAD Resize DirectShow Filter and Media Foundation Transform for use in their .NET (C# & VB) and C/C++ applications. This filter is used to resize videos with various subsampling algorithms, such as Bicubic, Bresenham, and Resample, with the purpose of improving playback quality on different screens or to reduce bandwidth requirements by streaming smaller video sizes. Video Resize can also be permanently applied during live capture or post-processing and is a key step in saving disk space.
