The TIFF/F files written by the fax library have the following tags with valid values, where x equals a number:

Table 23. TIFF/F Tags Output from Library

Field	Valid values	Description
BadFaxLines	x	number of bad scan lines received; this is a measure of quality of the image received from the remote
BitsPerSample	1	one bit per sample
CleanFaxData	0	data in file does not contain bad scan lines
		Bad Scan Line Replacement (BLR) restores MH encoded scan line to the correct pixel count, as indicated by CleanFaxData set to zero; however, the integrity of the repaired scan line image may be impaired. To determine the error content of the stored data, use BadFaxLines.
Compression	3	Group 3 - MH encoding
	4	Group 4 - MMR encoding
DateTime		YYYY:MM:DD HH:MM:SS
FillOrder	2	least significant bit first
ImageWidth	1728	number of pixels per line
	2048	number of pixels per line
	2432	number of pixels per line
ImageLength	x	number of scan lines in image
NewSubFileType	2	single page in multi-page image
Orientation	1	first row = top left
		first column = top left
PageNumber	x/x	page number/number of pages
PhotometricInterpretation	0	gray scale/bilevel: zero = white
ResolutionUnit	2	inch
RowsPerStrip	x	number of scan lines in image; if present, RowsPerStrip must equal ImageLength.
SamplesPerPixel	1	one sample per pixel
Software		Dialogic TIFF/F Library version x.xx
StripByteCounts	x	byte count in image (as appropriate); only one value for StripOffsets and StripByteCounts must be present (the image is considered to be one large strip). Multiple strips per image is not currently supported.
StripOffsets	x	byte offset of image (as appropriate)
T4Options	0	Group 3 - MH encoding, EOL not padded
T6Options	0	Note: Replaces T4Options if MMR
Xresolution	204	number of pixels per resolution unit X
Yresolution	98	coarse (normal) (number of pixels per resolution unit Y)
	196	fine
