2 /* tiffcrop.c -- a port of tiffcp.c extended to include manipulations of
3 * the image data through additional options listed below

25 * DATA OR PROFITS, WHETHER OR NOT ADVISED OF THE POSSIBILITY OF DAMAGE, AND
26 * ON ANY THEORY OF LIABILITY, ARISING OUT OF OR IN CONNECTION WITH THE USE
27 * OR PERFORMANCE OF THIS SOFTWARE.
28 *
29 * Some portions of the current code are derived from tiffcp, primarly in
30 * the areas of lowlevel reading and writing of TAGS, scanlines and tiles though
31 * some of the original functions have been extended to support arbitrary bit
32 * depths. These functions are presented at the top of this file.
33 *
34 * Add support for the options below to extract sections of image(s)
35 * and to modify the whole image or selected portions of each image by
36 * rotations, mirroring, and colorscale/colormap inversion of selected
37 * types of TIFF images when appropriate. Some color model dependent
38 * functions are restricted to bilevel or 8 bit per sample data.
39 * See the man page for the full explanations.
40 *
41 * New Options:
42 * -h Display the syntax guide.
43 * -v Report the version and last build date for tiffcrop and libtiff.
44 * -z x1,y1,x2,y2:x3,y3,x4,y4:..xN,yN,xN + 1, yN + 1
45 * Specify a series of coordinates to define rectangular
46 * regions by the top left and lower right corners.
47 * -e c|d|i|m|s export mode for images and selections from input images
48 * combined All images and selections are written to a single file (default)
49 * with multiple selections from one image combined into a single image
50 * divided All images and selections are written to a single file
51 * with each selection from one image written to a new image
52 * image Each input image is written to a new file (numeric filename sequence)
53 * with multiple selections from the image combined into one image
54 * multiple Each input image is written to a new file (numeric filename sequence)
55 * with each selection from the image written to a new image
56 * separated Individual selections from each image are written to separate files
57 * -U units [in, cm, px ] inches, centimeters or pixels
58 * -H # Set horizontal resolution of output images to #
59 * -V # Set vertical resolution of output images to #
60 * -J # Horizontal margin of output page to # expressed in current
61 * units when sectioning image into columns x rows
62 * using the -S cols:rows option.
63 * -K # Vertical margin of output page to # expressed in current
64 * units when sectioning image into columns x rows
65 * using the -S cols:rows option.
66 * -X # Horizontal dimension of region to extract expressed in current
67 * units
68 * -Y # Vertical dimension of region to extract expressed in current
69 * units
70 * -O orient Orientation for output image, portrait, landscape, auto
71 * -P page Page size for output image segments, eg letter, legal, tabloid,
72 * etc.
73 * -S cols:rows Divide the image into equal sized segments using cols across
74 * and rows down
75 * -E t|l|r|b Edge to use as origin
76 * -m #,#,#,# Margins from edges for selection: top, left, bottom, right
77 * (commas separated)
78 * -Z #:#,#:# Zones of the image designated as zone X of Y,
79 * eg 1:3 would be first of three equal portions measured
80 * from reference edge
81 * -N odd|even|#,#-#,#|last
82 * Select sequences and/or ranges of images within file
83 * to process. The words odd or even may be used to specify
84 * all odd or even numbered images the word last may be used
85 * in place of a number in the sequence to indicate the final
86 * image in the file without knowing how many images there are.
87 * -R # Rotate image or crop selection by 90,180,or 270 degrees
88 * clockwise
89 * -F h|v Flip (mirror) image or crop selection horizontally
90 * or vertically
91 * -I [black|white|data|both]
92 * Invert color space, eg dark to light for bilevel and grayscale images
93 * If argument is white or black, set the PHOTOMETRIC_INTERPRETATION
94 * tag to MinIsBlack or MinIsWhite without altering the image data
95 * If the argument is data or both, the image data are modified:
96 * both inverts the data and the PHOTOMETRIC_INTERPRETATION tag,
97 * data inverts the data but not the PHOTOMETRIC_INTERPRETATION tag
98 * -D input:<filename1>,output:<filename2>,format:<raw|txt>,level:N,debug:N
99 * Dump raw data for input and/or output images to individual files
100 * in raw (binary) format or text (ASCII) representing binary data
101 * as strings of 1s and 0s. The filename arguments are used as stems
102 * from which individual files are created for each image. Text format
103 * includes annotations for image parameters and scanline info. Level
104 * selects which functions dump data, with higher numbers selecting
105 * lower level, scanline level routines. Debug reports a limited set
106 * of messages to monitor progess without enabling dump logs.
