XPR(1) General Commands Manual XPR(1) NAME xpr - print an X window dump SYNOPSIS xpr [ -device devtype ] [ -scale scale ] [ -height inches ] [ -width inches ] [ -left inches ] [ -top inches ] [ -header string ] [ -trailer string ] [ -landscape ] [ -portrait ] [ -plane number ] [ -gray ] [ -rv ] [ -compact ] [ -output filename ] [ -append filename ] [ -noff ] [ -split n ] [ -paper- type format ] [ -pheight inches [ units ]] [ -pwidth inches [ units ]] [ -psfig ] [ -density dpi ] [ -cutoff level ] [ -noposition ] [ -gamma cor- rection ] [ -render algorithm ] [ -slide ] [ -version ] [ filename ] DESCRIPTION xpr takes as input a window dump file produced by xwd(1) and formats it for output on PostScript printers, the IBM PP3812 page printer, the HP LaserJet (or other PCL printers), or the HP PaintJet. If no file argument is given, the standard input is used. By default, xpr prints the largest possible representation of the window on the output page. Options allow the user to add headers and trailers, specify margins, adjust the scale and orienta- tion, and append multiple window dumps to a single output file. Output is to standard output unless -output is specified. Command Options -device devtype Specifies the device on which the file will be printed. Currently supported: ljet HP LaserJet series and other monochrome PCL devices such as ThinkJet, QuietJet, RuggedWriter, HP2560 series, and HP2930 series printers pjet HP PaintJet (color mode) pjetxl HP PaintJet XL Color Graphics Printer (color mode) pp IBM PP3812 ps PostScript printer The default is PostScript. -device lw (LaserWriter) is equivalent to -device ps and is provided only for backwards compatibility. -scale scale Affects the size of the window on the page. The PostScript and HP printers are able to translate each bit in a window pixel map into a grid of a specified size. For example each bit might translate into a 3x3 grid. This would be specified by -scale 3. By default a win- dow is printed with the largest scale that will fit onto the page for the specified orientation. -height inches Specifies the maximum height of the page. -width inches Specifies the maximum width of the page. -left inches Specifies the left margin in inches. Fractions are allowed. By de- fault the window is centered in the page. -top inches Specifies the top margin for the picture in inches. Fractions are allowed. -header string Specifies a header string to be printed above the window. -trailer string Specifies a trailer string to be printed below the window. -landscape Forces the window to printed in landscape mode. By default a window is printed such that its longest side follows the long side of the paper. -plane number Specifies which bit plane to use in an image. The default is to use the entire image and map values into black and white based on color intensities. -gray 2 | 3 | 4 Uses a simple 2x2, 3x3, or 4x4 gray scale conversion on a color im- age, rather than mapping to strictly black and white. This doubles, triples, or quadruples the effective width and height of the image. -portrait Forces the window to be printed in portrait mode. By default a win- dow is printed such that its longest side follows the long side of the paper. -rv Forces the window to be printed in reverse video. -compact Uses simple run-length encoding for compact representation of win- dows with lots of white pixels. -output filename Specifies an output file name. If this option is not specified, standard output is used. -append filename Specifies a filename previously produced by xpr to which the window is to be appended. -noff When specified in conjunction with -append, the window will appear on the same page as the previous window. -split n This option allows the user to split a window onto several pages. This might be necessary for very large windows that would otherwise cause the printer to overload and print the page in an obscure man- ner. -papertype format Specifies the output paper format. Currently supported: letter letter size 8.5x11 inches legal legal size 8.5x14 inches A0 A0 size 841x1189 mm or 33.11x46.81 inches A1 A1 size 594x841 mm or 23.39x33.11 inches A2 A2 size 420x594 mm or 16.54x23.39 inches A3 A3 size 297x420 mm or 11.69x16.54 inches A4 A4 size 210x297 mm or 8.27x11.69 inches A5 A5 size 148x210 mm or 5.83x 8.27 inches A6 A6 size 105x148 mm or 4.13x 5.83 inches A7 A7 size 74x105 mm or 2.91x 4.13 inches A8 A8 size 52x74 mm or 2.05x 2.91 inches A9 A9 size 37x52 mm or 1.46x 2.05 inches A10 A10 size 26x37 mm or 1.02x 1.46 inches B0 B0 size 1000x1414 mm or 39.37x55.67 B1 B1 size 707x1000 mm or 27.83x39.37 inches B2 B2 size 500x707 mm or 19.69x27.83 inches B3 B3 size 353x500 mm or 13.90x19.69 inches B4 B4 size 250x353 mm or 9.84x13.90 inches B5 B5 size 176x250 mm or 6.93x 9.84 inches B6 B6 size 125x176 mm or 4.92x 6.93 inches B7 B7 size 88x125 mm or 3.46x 4.92 inches B8 B8 size 62x88 mm or 2.44x 3.46 inches B9 B9 size 44x62 mm or 1.73x 2.44 inches B10 B10 size 31x44 mm or 1.22x 1.73 inches C0 C0 size 917x1297 mm or 36.10x51.06 inches C1 C1 size 648x917 mm or 25.51x36.10 inches C2 C2 size 458x648 mm or 18.03x25.51 inches C3 C3 size 324x458 mm or 12.76x18.03 inches C4 C4 size 229x324 mm or 9.02x12.76 inches C5 C5 size 162x229 mm or 6.38x 9.02 inches C6 C6 size 114x162 mm or 4.49x 6.38 inches C7 C7 size 81x114 mm or 3.19x 4.49 inches C8 C8 size 57x81 mm or 2.24x 3.19 inches C9 C9 size 40x57 mm or 1.57x 2.24 inches C10 C10 size 28x40 mm or 1.10x 1.57 inches -pheight inches [ units ] This option allows the user to specify a specific paper height. The default units are in inches (in), but may be overridden with cm or mm for centimeters or millimeters respectively. -pwidth inches [ units ] This option allows the user to specify a specific paper width. The default units are in inches (in), but may be overridden with cm or mm for centimeters or millimeters respectively. -psfig Suppress translation of the PostScript picture to the center of the page. -density dpi Indicates what dot-per-inch density should be used by the HP printer. -cutoff level Changes the intensity level where colors are mapped to either black or white for monochrome output on a LaserJet printer. The level is expressed as percentage of full brightness. Fractions are allowed. -noposition This option causes header, trailer, and image positioning command generation to be bypassed for LaserJet, PaintJet and PaintJet XL printers. -gamma correction This changes the intensity of the colors printed by PaintJet XL printer. The correction is a floating point value in the range 0.00 to 3.00. Consult the operator's manual to determine the correct value for the specific printer. -render algorithm This allows PaintJet XL printer to render the image with the best quality versus performance tradeoff. Consult the operator's manual to determine which algorithms are available. -slide This option allows overhead transparencies to be printed using the PaintJet and PaintJet XL printers. -version This option prints the program version information and exits. SEE ALSO xwd(1), xwud(1), X(7) LIMITATIONS Support for PostScript output currently cannot handle the -append, -noff or -split options. The -compact option is only supported for PostScript output. It compresses white space but not black space, so it is not useful for reverse-video win- dows. For color images, should map directly to PostScript image support. HP PRINTERS If no -density is specified on the command line 300 dots per inch will be assumed for ljet and 90 dots per inch for pjet. Allowable density values for a LaserJet printer are 300, 150, 100, and 75 dots per inch. Consult the operator's manual to determine densities supported by other printers. If no -scale is specified the image will be expanded to fit the printable page area. The default printable page area is 8x10.5 inches. Other paper sizes can be accommodated using the -height and -width options. Note that a 1024x768 image fits the default printable area when processed at 100 dpi with scale=1, the same image can also be printed using 300 dpi with scale=3 but will require considerably more data be transferred to the printer. xpr may be tailored for use with monochrome PCL printers other than the LaserJet. To print on a ThinkJet (HP2225A) xpr could be invoked as: xpr -density 96 -width 6.667 filename or for black-and-white output to a PaintJet: xpr -density 180 filename The monochrome intensity of a pixel is computed as 0.30*R + 0.59*G + 0.11*B. If a pixel's computed intensity is less than the -cutoff level it will print as white. This maps light-on-dark display images to black-on- white hardcopy. The default cutoff intensity is 50% of full brightness. Example: specifying -cutoff 87.5 moves the white/black intensity point to 87.5% of full brightness. A LaserJet printer must be configured with sufficient memory to handle the image. For a full page at 300 dots per inch approximately 2MB of printer memory is required. Color images are produced on the PaintJet at 90 dots per inch. The Paint- Jet is limited to sixteen colors from its 330 color palette on each hori- zontal print line. xpr will issue a warning message if more than sixteen colors are encountered on a line. xpr will program the PaintJet for the first sixteen colors encountered on each line and use the nearest matching programmed value for other colors present on the line. Specifying the -rv, reverse video, option for the PaintJet will cause black and white to be interchanged on the output image. No other colors are changed. Multiplane images must be recorded by xwd in ZPixmap format. Single plane (monochrome) images may be in either XYPixmap or ZPixmap format. Some PCL printers do not recognize image positioning commands. Output for these printers will not be centered on the page and header and trailer strings may not appear where expected. The -gamma and -render options are supported only on the PaintJet XL print- ers. The -slide option is not supported for LaserJet printers. The -split option is not supported for HP printers. The -gray option is not supported for HP or IBM printers. AUTHORS Michael R.
