public class MfHeader
A buffer which represents a Metafile header.
The meta file header has the following structureoffset | length in bytes | name | meaning |
---|---|---|---|
0x00 | 2 | mfType | MetaFile type: 0x1 = memory based meta file, 0x2 = disk based meta file |
0x02 | 2 | mfHeader | length of header in words (16bit) |
0x04 | 2 | mfVersion | Windows version used to save the file as BCD number. 0x30 for windows 3.0, 0x31 for win3.1 etc. |
0x06 | 4 | mfSize | File length in words |
0x0A | 2 | mfNoObj | maximum number of objects in the file |
0x0c | 4 | mfMaxRec | Maximum record length |
0x10 | 2 | mfnoPar | Not used |
