Introduction

DjVu# loads image files using Windows Imaging Component, which is introduced with .NET Framework 3.0. It supports loading of JPEG, TIFF, GIF, PNG, BMP and HD Photo files but it's also extensible using third-party components such as FastPictureViewer Codec Pack.

Normally Windows Imaging Component is introduced with .NET Framework 3.0. But you can install it separately by using redistributable module released by Microsoft.

TIFF variant support

Although Windows Imaging Component supports TIFF files, certain very tricky variants of TIFF files could not be opened correctly. To support these tricky files, DjVu# internally equips its own TIFF loading engine. It can handles TIFF files better than Windows Imaging Component but it still could not open some really problematic TIFF files.

Advanced file format support by LEADTOOLS®

DjVu# supports the last resort depending on LEADTOOLS®. It supports almost all known TIFF variants over the world and of course, it also supports wide variety of file formats.

The feature is not enabled by default. So if you want to use the feature, you should obtain Advanced file format support module, which includes LEADTOOLS runtime and DjVu# integration modules, and your code also explicitly enable it by obtaining valid license script from Cuminas. Anyway, please contact us for more information.
