Picture Descriptor (on File) (PICF)

b10	b16	field	type	size	bitfield	comments
0	0	lcb	long			number of bytes in the PIC structure plus size of following picture data which may be a Window's metafile, a bitmap, or the filename of a TIFF file. In the case of a Macintosh PICT picture, this includes the size of the PIC, the standard "x" metafile, and the Macintosh PICT data. See Appendix B for more information.
4	4	cbHeader	unsigned			number of bytes in the PIC (to allow for future expansion).
6	6	mfp.mm	short
8	8	mfp.xExt	short
10	A	mfp.yExt	short
12	C	mfp.hMF	short

If a Windows metafile is stored immediately following the PIC structure, the mfp is a Window's METAFILEPICT structure. When the data immediately following the PIC is a TIFF filename, mfp.mm == 98 If a bitmap is stored after the pic, mfp.mm == 99

When the PIC describes a bitmap, mfp.xExt is the width of the bitmap in pixels and mfp.yExt is the height of the bitmap in pixels..

14	E	bm	BITMAP (14 bytes)			Window's bitmap structure when PIC describes a BITMAP.
14	E	rcWinMF	rc (rectangle - 8 bytes)			rect for window origin and extents when metafile is stored -- ignored if 0
28	1C	dxaGoal	short			horizontal measurement in twips of the rectangle the picture should be imaged within.
30	1E	dyaGoal	short			vertical measurement in twips of the rectangle the picture should be imaged within.

when scaling bitmaps, dxaGoal and dyaGoal may be ignored if the operation would cause the bitmap to shrink or grow by a non -power-of-two factor

32	20	mx	uns short			horizontal scaling factor supplied by user expressed in .001% units.
34	22	my	uns short			vertical scaling factor supplied by user expressed in .001% units.

for all of the Crop values, a positive measurement means the specified border has been moved inward from its original setting and a negative measurement means the border has been moved outward from its original setting.

36	24	dxaCropLeft	short			the amount the picture has been cropped on the left in twips.
38	26	dyaCropTop	short			the amount the picture has been cropped on the top in twips.
40	28	dxaCropRight	short			the amount the picture has been cropped on the right in twips.
42	2A	dyaCropBottom	short			the amount the picture has been cropped on the bottom in twips.
44	2C	brcl	short	:4	000F	Obsolete, superseded by brcTop, etc. In WinWord 1.x, it was the type of border to place around picture 0 single 1 thick 2 double 3 shadow
		fFrameEmpty	short	:1	0010	picture consists of a single frame
		fBitmap	short	:1	0020	==1, when picture is just a bitmap
		fDrawHatch	short	:1	0040	==1, when picture is an active OLE object
		fError	short	:1	0080	==1, when picture is just an error message
		bpp	short	:8		bits per pixel 0 unknown 1 monochrome 4 VGA
46	2E	brcTop	BRC			specification for border above picture
50	32	brcLeft	BRC			specification for border to the left of
						picture
54	36	brcBottom	BRC			specification for border below picture
58	3A	brcRight	BRC			specification for border to the right of
						picture
62	3E	dxaOrigin	short			horizontal offset of hand annotation origin
64	40	dyaOrigin	short			vertical offset of hand annotation origin
66	42	cProps	short			unused
68	44	rgb				variable array of bytes containing Window's metafile, bitmap or TIFF file filename.
