The CMetaFile class is derived from CMetaFileDC and allows you to easily load metafiles from disk and display them. A metafile can also be displayed with various alignment options, in order to preserve aspect ratio, etc. The class include serialization, allowing you to embed a metafile into a CDocument, for example.
To use the class, simply include "meta.h" and create an instance:
To load a metafile from disk use one of the CMetaFile::Read functions. One takes a pointer to a filename string, the other a pointer to a pre-opened CFile object. The Read function will return FALSE if an error occurred loading the metafile.
If you want to check if a file is a valid metafile, there is a static CMetaFile::IsMetaFile function you can call. Pass a CFile pointer and the function returns true if it's a valid metafile image.
That's about it. The example project shows how to embed a metafile in a document and display it from a view. Examples of all the alignment options are included.
