These functions are presented at the top of this file. * * Add support for the options below to extract sections of image(s) * and to modify the whole image or selected portions of each image by * rotations, mirroring, and colorscale/colormap inversion of selected * types of TIFF images when appropriate. Some color model dependent * functions are restricted to bilevel or 8 bit per sample data. * See the man page for the full explanations. * * New Options: * -h Display the syntax guide. * -v Report the version and last build date for tiffcrop and libtiff. * -z x1,y1,x2,y2:x3,y3,x4,y4:..xN,yN,xN + 1, yN + 1 * Specify a series of coordinates to define rectangular * regions by the top left and lower right corners. * -e c|d|i|m|s export mode for images and selections from input images * combined All images and selections are written to a single file (default) * with multiple selections from one image combined into a single image * divided All images and selections are written to a single file * with each selection from one image written to a new image * image Each input image is written to a new file (numeric filename sequence) * with multiple selections from the image combined into one image * multiple Each input image is written to a new file (numeric filename sequence) * with each selection from the image written to a new image * separated Individual selections from each image are written to separate files * -U units [in, cm, px ] inches, centimeters or pixels * -H # Set horizontal resolution of output images to # * -V # Set vertical resolution of output images to # * -J # Horizontal margin of output page to # expressed in current * units when sectioning image into columns x rows * using the -S cols:rows option. * -K # Vertical margin of output page to # expressed in current * units when sectioning image into columns x rows * using the -S cols:rows option. * -X # Horizontal dimension of region to extract expressed in current * units * -Y # Vertical dimension of region to extract expressed in current * units * -O orient Orientation for output image, portrait, landscape, auto * -P page Page size for output image segments, eg letter, legal, tabloid, * etc. * -S cols:rows Divide the image into equal sized segments using cols across * and rows down * -E t|l|r|b Edge to use as origin * -m #,#,#,# Margins from edges for selection: top, left, bottom, right * (commas separated) * -Z #:#,#:# Zones of the image designated as zone X of Y, * eg 1:3 would be first of three equal portions measured * from reference edge * -N odd|even|#,#-#,#|last * Select sequences and/or 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. * -R # Rotate image or crop selection by 90,180,or 270 degrees * clockwise * -F h|v Flip (mirror) image or crop selection horizontally * or vertically * -I [black|white|data|both] * Invert color space, eg dark to light for bilevel and grayscale images * If argument is white or black, set the PHOTOMETRIC_INTERPRETATION * tag to MinIsBlack or MinIsWhite without altering the image data * If the argument is data or both, the image data are modified: * both inverts the data and the PHOTOMETRIC_INTERPRETATION tag, * data inverts the data but not the PHOTOMETRIC_INTERPRETATION tag * -D input:<filename1>,output:<filename2>,format:<raw|txt>,level:N,debug:N * Dump raw data for input and/or output images to individual files * in raw (binary) format or text (ASCII) representing binary data * as strings of 1s and 0s. The filename arguments are used as stems * from which individual files are created for each image. Text format * includes annotations for image parameters and scanline info. Level * selects which functions dump data, with higher numbers selecting * lower level, scanline level routines. Debug reports a limited set * of messages to monitor progess without enabling dump logs. */ static char tiffcrop_version_id[] = "2.4"; static char tiffcrop_rev_date[] = "12-13-2010"; #include "tif_config.h" #include "tiffiop.h" #include <stdio.h> #include <stdlib.h> #include <string.h> #include <math.h> #include <ctype.h> #include <limits.h> #include <sys/stat.h> #include <assert.h> #ifdef HAVE_UNISTD_H # include <unistd.h> #endif #ifdef HAVE_STDINT_H # include <stdint.h> #endif #ifndef HAVE_GETOPT extern int getopt(int, char**, char*); #endif #ifdef NEED_LIBPORT # include "libport.h" #endif #include "tiffio.h" #if defined(VMS) # define unlink delete #endif #ifndef PATH_MAX #define PATH_MAX 1024 #endif #ifndef streq #define streq(a,b) (strcmp((a),(b)) == 0) #endif #define strneq(a,b,n) (strncmp((a),(b),(n)) == 0) #define TRUE 1 #define FALSE 0 #ifndef TIFFhowmany #define TIFFhowmany(x, y) ((((uint32)(x))+(((uint32)(y))-1))/((uint32)(y))) #define TIFFhowmany8(x) (((x)&0x07)?((uint32)(x)>>3)+1:(uint32)(x)>>3) #endif /* * Definitions and data structures required to support cropping and image * manipulations. */ #define EDGE_TOP 1 #define EDGE_LEFT 2 #define EDGE_BOTTOM 3 #define EDGE_RIGHT 4 #define EDGE_CENTER 5 #define MIRROR_HORIZ 1 #define MIRROR_VERT 2 #define MIRROR_BOTH 3 #define ROTATECW_90 8 #define ROTATECW_180 16 #define ROTATECW_270 32 #define ROTATE_ANY ROTATECW_90 || ROTATE
