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.)
