OCR Xpress for Linux generically interfaces with other Accusoft components as well as third-party components by accepting a DIB (Device Independent Bitmap) as input. Any DIB with a supported image format can be passed to OCR Xpress for Linux recognize functions. For details on interfacing with ImageGear for C/C++, refer to the igpro_integration sample in the "samples" folder of your OCR Xpress for Linux install directory.
