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. * * HDMD - 14/4/1999 */ #include "config.h" #include <stdarg.h> #include <string.h> #include <fcntl.h> #include "windef.h" #include "winbase.h" #include "wingdi.h" #include "winreg.h" #include "winnls.h" #include "winternl.h" #include "gdi_private.h" #include "wine/debug.h" WINE_DEFAULT_DEBUG_CHANNEL(metafile); #include "pshpack1.h" typedef struct { DWORD dw1, dw2, dw3; WORD w4; CHAR filename[0x100]; } METAHEADERDISK; #include "poppack.h" typedef struct { GDIOBJHDR header; METAHEADER *mh; } METAFILEOBJ; /****************************************************************** * MF_AddHandle * * Add a handle to an external handle table and return the index */ static int MF_AddHandle(HANDLETABLE *ht, UINT htlen, HGDIOBJ hobj) { int i; for (i = 0; i < htlen; i++) { if (*(ht->objectHandle + i) == 0) { *(ht->objectHandle + i) = hobj; return i; } } return -1; } /****************************************************************** * MF_Create_HMETATFILE * * Creates a (32 bit) HMETAFILE object from a METAHEADER * * HMETAFILEs are GDI objects. */ HMETAFILE MF_Create_HMETAFILE(METAHEADER *mh) { HMETAFILE hmf; METAFILEOBJ *metaObj; if (!(metaObj = HeapAlloc( GetProcessHeap(), 0, sizeof(*metaObj) ))) return 0; metaObj->mh = mh; if (!(hmf = alloc_gdi_handle( &metaObj->header, OBJ_METAFILE, NULL ))) HeapFree( GetProcessHeap(), 0, metaObj ); return hmf; } /****************************************************************** * MF_GetMetaHeader * * Returns ptr to METAHEADER associated with HMETAFILE */ static METAHEADER *MF_GetMetaHeader( HMETAFILE hmf ) { METAHEADER *ret = NULL; METAFILEOBJ * metaObj = GDI_GetObjPtr( hmf, OBJ_METAFILE ); if (metaObj) { ret = metaObj->mh; GDI_ReleaseObj( hmf ); } return ret; } /****************************************************************** * convert_points * * Convert an array of POINTS to an array of POINT. * Result must be freed by caller. */ static POINT *convert_points( UINT count, const POINTS *pts ) { UINT i; POINT *ret = HeapAlloc( GetProcessHeap(), 0, count * sizeof(*ret) ); if (ret) { for (i = 0; i < count; i++) { ret[i].x = pts[i].x; ret[i].y = pts[i].y; } } return ret; } /****************************************************************** * DeleteMetaFile (GDI32.@) * * Delete a memory-based metafile. */ BOOL WINAPI DeleteMetaFile( HMETAFILE hmf ) { METAFILEOBJ * metaObj = free_gdi_handle( hmf ); if (!metaObj) return FALSE; HeapFree( GetProcessHeap(), 0, metaObj->mh ); return HeapFree( GetProcessHeap(), 0, metaObj ); } /****************************************************************** * MF_ReadMetaFile * * Returns a pointer to a memory based METAHEADER read in from file HFILE * */ static METAHEADER *MF_ReadMetaFile(HANDLE hfile) { METAHEADER *mh; DWORD BytesRead, size; size = sizeof(METAHEADER); mh = HeapAlloc( GetProcessHeap(), 0, size ); if(!mh) return NULL; if(ReadFile( hfile, mh, size, &BytesRead, NULL) == 0 || BytesRead != size) { HeapFree( GetProcessHeap(), 0, mh ); return NULL; } if (mh->mtType != METAFILE_MEMORY || mh->mtVersion != MFVERSION || mh->mtHeaderSize != size / 2) { HeapFree( GetProcessHeap(), 0, mh ); return NULL; } size = mh->mtSize * 2; mh = HeapReAlloc( GetProcessHeap(), 0, mh, size ); if(!mh) return NULL; size -= sizeof(METAHEADER); if(ReadFile( hfile, (char *)mh + sizeof(METAHEADER), size, &BytesRead, NULL) == 0 || BytesRead != size) { HeapFree( GetProcessHeap(), 0, mh ); return NULL; } if (mh->mtType != METAFILE_MEMORY) { WARN("Disk metafile had mtType = %04x\n", mh->mtType); mh->mtType = METAFILE_MEMORY; } return mh; } /****************************************************************** * GetMetaFileA (GDI32.@) * * Read a metafile from a file.
