NAME

+ + + + + +

tiffcrop − copy (and possibly convert and crop or +process) a TIFF file

+ +

SYNOPSIS

+ + + + + +

tiffcrop [ options ] src1.tif ... +srcN.tif dst.tif

+ +

DESCRIPTION

+ + + + + +

tiffcrop combines one or more files created +according to the Tag Image File Format, Revision 6.0 into a +single TIFF file. The output file may be +compressed using a different algorithm than the input files. +tiffcrop is most often used to extract portions of an +image for processing with bar code recognizer or OCR +software when that software cannot restrict the region of +interest to a specific portion of the image or to improve +efficiency when the regions of interest must be rotated.

+ +

By default, tiffcrop will copy all the understood +tags in a TIFF directory of an input file to +the associated directory in the output file.

+ +

tiffcrop can be used to reorganize the storage +characteristics of data in a file, and it will alter or +convert the image data content as specified at the same +time, unlike tiffcp.

+ +

tiffcrop will behave exactly like tiffcp if none +of the new options are specified.

+ +

OPTIONS

+ + + + + +

−N odd|even|#,#-#,#|last

+ + + + + +

sequences and ranges of images within file to process. +The words odd or even may be used to specify +all odd or even numbered images. The word last may be +used in place of a number in the sequence to indicate the +final image in the file without knowing how many images +there are. Ranges of images may be specified with a dash and +multiple sets can be indicated by joining them in a +comma-separated list. e.g.. use −N 1,5-7,last +to process the 1st, 5th through 7th, and final image in the +file.

+ + + + + +

−E top|bottom|left|right

+ + + + + +

use the top, bottom, left, or right edge as origin +reference for width and length of crop regions. May be +abbreviated to first letter.

+ + + + + +

−U in|cm|px

+ + + + + +

units to apply to dimensions for margins and crop +regions. Inches or centimeters are converted to pixels using +the resolution unit specified in the TIFF file (which +defaults to inches if not specified in the IFD).

+ + + + + +

−m #,#,#,#

+ + + + + +

margins to be removed from the image. The order must be +top, left, bottom, right with only commas separating the +elements of the list. Margins are scaled according to the +current units and removed before any other extractions are +computed. Capital M was in use.

+ + + + + + + + + + + + + + +

	+ + −X # +		+ + horizontal (X-axis) dimension of a region to extract +relative to the specified origin reference. If the origin is +the top or bottom edge, the X axis value will be assumed to +start at the left edge. +	+
	+ + −Y # +		+ + vertical (Y-axis) dimension of a region to extract +relative to the specified origin reference. If the origin is +the left or right edge, the Y axis value will be assumed to +start at the top. +	+

+ + + + + +

−Z #:#,#:#

+ + + + + +

zones of the image designated as position X of Y equal +sized portions measured from the reference edge, e.g. 1:3 +would be first third of the image starting from the +reference edge minus any margins specified for the confining +edges. Multiple zones can be specified as a comma separated +list but they must reference the same edge. To extract the +top quarter and the bottom third of an image you would use +−Z 1:4,3:3.

+ + + + + +

−F horiz|vert

+ + + + + +

flip, i.e. mirror, the image or extracted region +horizontally or vertically.

+ + + + + +

−R 90|180|270

+ + + + + +

rotate the image or extracted region 90, 180, or 270 +degrees clockwise.

+ + + + + + + + +

+ +

−I

+ +

invert the colorspace values for grayscale and bi-level +images. This would be used to correct negative images that +have incorrect PHOTOMETRIC INTERPRETATION tags. No support +for color images.

+ + + + + +

−b image

+ + + + + +

subtract the following monochrome image from all others +processed. This can be used to remove a noise bias from a +set of images. This bias image is typically an image of +noise the camera saw with its shutter closed. Bias image +support is not available with options for cropping, +rotating, or inverting the image.

+ + + + + + + + + + + + + + + + + + + + +

+ + −B +	+ + Force output to be written with Big-Endian byte order. +This option only has an effect when the output file is +created or overwritten and not when it is appended to. +	+
+ + −C +	+ + Suppress the use of ‘‘strip +chopping’’ when reading images that have a +single strip/tile of uncompressed data. +	+
+ + −c +	+ + Specify the compression to use for data written to the +output file: none for no compression, packbits +for PackBits compression, lzw for Lempel-Ziv & +Welch compression, jpeg for baseline JPEG +compression, zip for Deflate compression, g3 +for CCITT Group 3 (T.4) compression, and g4 for CCITT +Group 4 (T.6) compression. By default tiffcrop will +compress data according to the value of the +Compression tag found in the source file. +	+

+ + + + + +

The CCITT Group 3 and Group 4 compression +algorithms can only be used with bi-level data.

+ +

Group 3 compression can be specified together with +several T.4-specific options: 1d for 1-dimensional +encoding, 2d for 2-dimensional encoding, and +fill to force each encoded scanline to be zero-filled +so that the terminating EOL code lies on a byte boundary. +Group 3-specific options are specified by appending a +‘‘:’’-separated list to the +‘‘g3’’ option; e.g. −c +g3:2d:fill to get 2D-encoded data with byte-aligned EOL +codes.

+ +

LZW compression can be specified together +with a predictor value. A predictor value of 2 causes +each scanline of the output image to undergo horizontal +differencing before it is encoded; a value of 1 forces each +scanline to be encoded without differencing. LZW-specific +options are specified by appending a +‘‘:’’-separated list to the +‘‘lzw’’ option; e.g. −c +lzw:2 for LZW compression with horizontal +differencing.

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

+ + −f +	+ + Specify the bit fill order to use in writing output +data. By default, tiffcrop will create a new file +with the same fill order as the original. Specifying +−f lsb2msb will force data to be written with +the FillOrder tag set to LSB2MSB, while +−f msb2lsb will force data to be written with +the FillOrder tag set to MSB2LSB. +	+
+ + −i +	+ + Ignore non-fatal read errors and continue processing of +the input file. +	+
+ + −l +	+ + Specify the length of a tile (in pixels). +tiffcrop attempts to set the tile dimensions so that +no more than 8 kilobytes of data appear in a tile. +	+
+ + −L +	+ + Force output to be written with Little-Endian byte +order. This option only has an effect when the output file +is created or overwritten and not when it is appended +to. +	+
+ + −M +	+ + Suppress the use of memory-mapped files when reading +images. +	+
+ + −p +	+ + Specify the planar configuration to use in writing image +data that has one 8-bit sample per pixel. By default, +tiffcrop will create a new file with the same planar +configuration as the original. Specifying −p +contig will force data to be written with multi-sample +data packed together, while −p separate will +force samples to be written in separate planes. +	+
+ + −r +	+ + Specify the number of rows (scanlines) in each strip of +data written to the output file. By default (or when value +0 is specified), tiffcrop attempts to set the +rows/strip that no more than 8 kilobytes of data appear in a +strip. If you specify special value -1 it will +results in infinite number of the rows per strip. The entire +image will be the one strip in that case. +	+
+ + −s +	+ + Force the output file to be written with data organized +in strips (rather than tiles). +	+
+ + −t +	+ + Force the output file to be written with data organized +in tiles (rather than strips). options can be used to force +the resultant image to be written as strips or tiles of +data, respectively. +	+
+ + −w +	+ + Specify the width of a tile (in pixels). tiffcrop +attempts to set the tile dimensions so that no more than 8 +kilobytes of data appear in a tile. tiffcrop attempts +to set the tile dimensions so that no more than 8 kilobytes +of data appear in a tile. +	+

+ + + + + +

−,={character}

+ + + + + +

substitute {character} for ’,’ in parsing +image directory indices in files. This is necessary if +filenames contain commas. Note that ’,=’ with +whitespace immediately following will disable the special +meaning of the ’,’ entirely. See examples.

+ +

EXAMPLES

+ + + + + +

The following concatenates two files and writes the +result using LZW encoding:

+ + + + + +

tiffcrop -c lzw a.tif b.tif result.tif
+

+ + + + + + +

To convert a G3 1d-encoded TIFF to a +single strip of G4-encoded data the following might be +used:

+ + + + + +

tiffcrop -c g4 -r 10000 g3.tif g4.tif
+

+ + + + + + +

(1000 is just a number that is larger than the number of +rows in the source file.)

+ +

To extract a selected set of images from a multi-image +TIFF file use the -N option described above. Thus, to copy +the 1st and 3rd images of image file "album.tif" +to "result.tif":

+ + + + + +

tiffcrop -N 1,3 album.tif result.tif
+

+ + + + + + +

Given file "CCD.tif" whose first image is a +noise bias followed by images which include that bias, +subtract the noise from all those images following it (while +decompressing) with the command:

+ + + + + +

tiffcrop -c none -b CCD.tif CCD.tif -d 2 result.tif
+
