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