Description

Aldus Corperation created the Placeable Metafile to specify how a metafile is to be mapped and scaled on output devices. These files are not supported by the Windows API due to the placeable metafile having a 22-byte header.

Here is an example of a APM Header.

typedef struct
     {
     DWORD   key;
     HANDLE  hmf;
     RECT    bbox;
     WORD    inch;
     DWORD   reserved;
     WORD    checksum;
     } APMFILEHEADER;

To playback a placeable metafile in Windows you need to save the file the open it in a Hex Editior and remove the header that starts at Offset 0x16.

Today APM belongs to Adobe Systems due to Aldus Corperation being merged with Adobe Systems in 1994.
