/* * Metafile functions * * Copyright David W. Metcalfe, 1994 * Niels de Carpentier, Albrecht Kleine, Huw Davies 1996 * */ /* * 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. * * HDMD - 14/4/1999 */ #include #include #include "wine/winbase16.h" #include "metafile.h" #include "bitmap.h" #include "heap.h" #include "toolhelp.h" #include "debugtools.h" #include "global.h" DEFAULT_DEBUG_CHANNEL(metafile) /****************************************************************** * MF_AddHandle * * Add a handle to an external handle table and return the index */ static int MF_AddHandle(HANDLETABLE16 *ht, WORD htlen, HGDIOBJ16 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 = GDI_AllocObject( sizeof(METAFILEOBJ), METAFILE_MAGIC ); METAFILEOBJ *metaObj = (METAFILEOBJ *)GDI_HEAP_LOCK( hmf ); metaObj->mh = mh; GDI_HEAP_UNLOCK( hmf ); return hmf; } /****************************************************************** * MF_Create_HMETATFILE16 * * Creates a HMETAFILE16 object from a METAHEADER * * HMETAFILE16s are Global memory handles. */ HMETAFILE16 MF_Create_HMETAFILE16(METAHEADER *mh) { HMETAFILE16 hmf; DWORD size; if(mh->mtType == METAFILE_MEMORY) size = mh->mtSize * sizeof(WORD); else size = sizeof(METAHEADER) + sizeof(METAHEADERDISK); hmf = GLOBAL_CreateBlock( GMEM_MOVEABLE, mh, mh->mtSize * sizeof(WORD), GetCurrentPDB16(), FALSE, FALSE, FALSE ); return hmf; } /****************************************************************** * MF_GetMetaHeader * * Returns ptr to METAHEADER associated with HMETAFILE * Should be followed by call to MF_ReleaseMetaHeader */ static METAHEADER *MF_GetMetaHeader( HMETAFILE hmf ) { METAFILEOBJ * metaObj = (METAFILEOBJ *)GDI_GetObjPtr( hmf, METAFILE_MAGIC ); return metaObj ? metaObj->mh : 0; } /****************************************************************** * MF_GetMetaHeader16 * * Returns ptr to METAHEADER associated with HMETAFILE16 * Should be followed by call to MF_ReleaseMetaHeader16 */ static METAHEADER *MF_GetMetaHeader16( HMETAFILE16 hmf ) { return GlobalLock16(hmf); } /****************************************************************** * MF_ReleaseMetaHeader * * Releases METAHEADER associated with HMETAFILE */ static BOOL MF_ReleaseMetaHeader( HMETAFILE hmf ) { return GDI_HEAP_UNLOCK( hmf ); } /****************************************************************** * MF_ReleaseMetaHeader16 * * Releases METAHEADER associated with HMETAFILE16 */ static BOOL16 MF_ReleaseMetaHeader16( HMETAFILE16 hmf ) { return GlobalUnlock16( hmf ); } /****************************************************************** * DeleteMetaFile16 (GDI.127) */ BOOL16 WINAPI DeleteMetaFile16( HMETAFILE16 hmf ) { return !GlobalFree16( hmf ); } /****************************************************************** * DeleteMetaFile (GDI32.69) * * Delete a memory-based metafile. */ BOOL WINAPI DeleteMetaFile( HMETAFILE hmf ) { METAHEADER *mh = MF_GetMetaHeader( hmf ); if(!mh) return FALSE; HeapFree( GetProcessHeap(), 0, mh ); GDI_FreeObject( hmf ); return TRUE; } /****************************************************************** * MF_ReadMetaFile * * Returns a pointer to a memory based METAHEADER read in from file HFILE * */ static METAHEADER *MF_ReadMetaFile(HFILE 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; } 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; } /****************************************************************** * GetMetaFile16 (GDI.124) */ HMETAFILE16 WINAPI GetMetaFile16( LPCSTR lpFilename ) { METAHEADER *mh; HFILE hFile; TRACE("%s\n", lpFilename); if(!lpFilename) return 0; if((hFile = CreateFileA(lpFilename, GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, 0, -1)) == HFILE_ERROR) return 0; mh = MF_ReadMetaFile(hFile); CloseHandle(hFile); if(!mh) return 0; return MF_Create_HMETAFILE16( mh ); } /****************************************************************** * GetMetaFileA (GDI32.197) * * Read a metafile from a file.
