Import allows X % users to store window images in a specially formatted dump file. This % file can then be read by the Display utility for redisplay, printing, % editing, formatting, archiving, image processing, etc. The target % window can be specified by id or name or be selected by clicking the % mouse in the desired window. The keyboard bell is rung once at the % beginning of the dump and twice when the dump is completed. % % The import program command syntax is: % % Usage: import [options ...] file % % Where options include: % -border include image borders in the output image % -colors value preferred number of colors in the image % -colorspace type GRAY, OHTA, RGB, XYZ, YCbCr, YIQ, YPbPr, or YUV % -comment string annotate image with comment % -compress type RunlengthEncoded or QEncoded % -crop geometry preferred size and location of the cropped image % -delay seconds pause before selecting target window % -density geometry vertical and horizontal density of the image % -descend obtain image by descending window hierarchy % -display server X server to contact % -frame include window manager frame % -geometry geometry perferred size or location of the image % -interlace type NONE, LINE, or PLANE % -label name assign a label to an image % -monochrome transform image to black and white % -negate apply color inversion to image % -page geometry size and location of the Postscript page % -quality value JPEG quality setting % -rotate degrees apply Paeth rotation to the image % -scene value image scene number % -screen select image from root window % -treedepth value depth of the color classification tree % -verbose print detailed information about the image % -window id select window with this id or name % % Change '-' to '+' in any option above to reverse its effect. % For example, +frame means do not window manager frame. % % By default, 'file' is written in the Postscript image format. To specify % a particular image format, precede the filename with an image format % name and a colon (i.e. ps:image) or specify the image type as the % filename suffix (i.e. image.ps). Specify 'file' as '-' for standard % input or output. % % */ /* Include declarations. */ #include "magick.h" #include "image.h" #include "X.h" /* %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % % % % % % % U s a g e % % % % % % % %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % % Procedure Usage displays the program usage; % % The format of the Usage routine is: % % Usage() % % */ static void Usage() { char **p; static char *options[]= { "-border include image borders in the output image", "-colors value preferred number of colors in the image", "-colorspace type GRAY, OHTA, RGB, XYZ, YCbCr, YIQ, YPbPr, or YUV", "-comment string annotate image with comment", "-compress type RunlengthEncoded or QEncoded", "-crop geometry preferred size and location of the cropped image", "-delay seconds pause before selecting target window", "-density geometry vertical and horizontal density of the image", "-descend obtain image by descending window hierarchy", "-display server X server to contact", "-frame include window manager frame", "-geometry geometry perferred size or location of the image", "-interlace type NONE, LINE, or PLANE", "-label name assign a label to an image", "-monochrome transform image to black and white", "-negate apply color inversion to image", "-page geometry size and location of the Postscript page", "-quality value JPEG quality setting", "-rotate degrees apply Paeth rotation to the image", "-scene value image scene number", "-treedepth value depth of the color classification tree", "-screen select image from root window", "-verbose print detailed information about the image", "-window id select window with this id or name", (char *) NULL }; (void) fprintf(stderr,"Version: %s\n\n",Version); (void) fprintf(stderr,"Usage: %s [options ...] file\n",client_name); (void) fprintf(stderr,"\nWhere options include:\n"); for (p=options; *p != (char *) NULL; p++) (void) fprintf(stderr," %s\n",*p); (void) fprintf(stderr, "\nChange '-' to '+' in any option above to reverse its effect.\n"); (void) fprintf(stderr, "For example, +frame means do not include window manager frame.\n"); (void) fprintf(stderr, "\nBy default, 'file' is written in the Postscript image format.
