25 * These functions are primarily involved with metafile playback or anything
26 * that touches a HMETAFILE.
27 * For recording of metafiles look in graphics/metafiledrv/
29 * Note that (32 bit) HMETAFILEs are GDI objects, while HMETAFILE16s are
30 * global memory handles so these cannot be interchanged.
32 * Memory-based metafiles are just stored as a continuous block of memory with
33 * a METAHEADER at the head with METARECORDs appended to it. mtType is
34 * METAFILE_MEMORY (1). Note this is identical to the disk image of a
35 * disk-based metafile - even mtType is METAFILE_MEMORY.
36 * 16bit HMETAFILE16s are global handles to this block
37 * 32bit HMETAFILEs are GDI handles METAFILEOBJs, which contains a ptr to
39 * Disk-based metafiles are rather different. HMETAFILE16s point to a
40 * METAHEADER which has mtType equal to METAFILE_DISK (2). Following the 9
41 * WORDs of the METAHEADER there are a further 3 WORDs of 0, 1 of 0x117, 1
42 * more 0, then 2 which may be a time stamp of the file and then the path of
43 * the file (METAHEADERDISK). I've copied this for 16bit compatibility.
