To playback a placeable metafile using the Windows API, +// you will first need to strip the placeable metafile header from the file. +// This is typically performed by copying the metafile to a temporary file +// starting at file offset 22 (0x16). The contents of the temporary file may +// then be used as input to the Windows GetMetaFile(), PlayMetaFile(), +// CopyMetaFile(), etc. GDI functions. + +// Each placeable metafile begins with a 22-byte header, +// followed by a standard metafile: + +#include // set structure packing to 2 + +typedef struct +{ + INT16 Left; + INT16 Top; + INT16 Right; + INT16 Bottom; +} APMRect16; + +typedef struct +{ + UINT32 Key; // GDIP_WMF_ALDUSKEY + INT16 Hmf; // Metafile HANDLE number (always 0) + APMRect16 BoundingBox; // Coordinates in metafile units + INT16 Inch; // Number of metafile units per inch + UINT32 Reserved; // Reserved (always 0) + INT16 Checksum; // Checksum value for previous 10 WORDs +} APMFileHeader; + +#include + +// Key contains a special identification value that indicates the presence +// of a placeable metafile header and is always 0x9AC6CDD7. + +// Handle is used to stored the handle of the metafile in memory.
