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
-
