libUEMF

libUEMF is a portable C99 implementation for reading and writing Windows Metafile, Enhanced Metafile, and Enhanced Metafile Plus (WMF, EMF, and EMF+) files. libUEMF avoids collisions with Microsoft defined functions and values, so portable programs which use it and have a Windows version do not require any conditional logic to separate the native GDI/GDI+ support from the equivalent functions provided by libUEMF. libUEMF does not implement GDI/GDI+ calls. Instead, for each metafile record type, and each object type incorporated into such a record, it provides corresponding *_set, *_get, *_print, and *_swap functions. Additional functions are provided for assembling the metafile in memory, debugging, and providing any needed byte swapping (an EMF file’s internal data representation is always Little Endian.)

Today’s small-to-medium-sized (SMB) businesses and large enterprises are saving on their monthly communications costs by making one simple decision: to switch to a VoIP service solution from their old, outdated Plain Old Telephone Service (POTS). By choosing a new VoIP service, these companies enjoy the flexibility, reliability, call features, and audio quality that only a VoIP service can provide. Plus, they cut their phone bill by up to 70%!
