/*
|
|
* 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 indentical 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.
