It is used to preview DVI files, such as are produced by TeX. This program has the capability of showing the file shrunken by various (integer) factors, and also has a ``magnifying glass'' which allows one to see a small part of the unshrunk image momentarily. Before displaying any page or part thereof, it checks to see if the dvi file has changed since the last time it was displayed. If this is the case, then _x_d_v_i will reinitialize itself for the new dvi file. For this reason, exposing parts of the _x_d_v_i window while _T_e_X is running should be avoided. This feature allows you to preview many versions of the same file while running _x_d_v_i only once. OOPPTTIIOONNSS In addition to specifying the .ddvvii file (with or without the .ddvvii), _X_d_v_i supports the following command line options. If the option begins with a `++' instead of a `--', the option is restored to its default value. By default, these options can be set via the resource names given in parentheses in the description of each option. +ppaaggee Specifies the first page to show. If + is given without a number, the last page is assumed; the first page is the default. --ss _s_h_r_i_n_k (.shrinkFactor) Defines the initial shrink factor. The default value is 3. --SS _d_e_n_s_i_t_y (.densityPercent) Determines the density used when shrinking bitmaps for fonts. A higher value produces a lighter font. The default value is 40. --pp _p_i_x_e_l_s (.pixelsPerInch) Defines the size of the fonts to use, X Version 11 8 May 1989 1 XDVI UNKNOWN MANUAL SECTION XDVI in pixels per inch. The default value is 300. --aallttffoonntt _f_o_n_t (.altFont) Declares a default font to use when the font in the dvi file cannot be found. This is useful, for example, with PostScript <tm> fonts. --ll (.listFonts) Causes the names of the fonts used to be listed. --rrvv (.reverseVideo) Causes the page to be displayed with white characters on a black background, instead of vice versa. --bbww _w_i_d_t_h (.borderWidth) Specifies the width of the border of the window. --bboorrddeerrwwiiddtthh _w_i_d_t_h Same as --bbww, above. --ffgg _c_o_l_o_r (.foreground) Determines the color of the text (fore- ground). --ffoorreeggrroouunndd _c_o_l_o_r Same as --ffgg, above. --bbgg _c_o_l_o_r (.background) Determines the color of the background. --bbaacckkggrroouunndd _c_o_l_o_r Same as --bbgg, above. --hhll _c_o_l_o_r (.highlight) Determines the color of the page border. --bbdd _c_o_l_o_r (.borderColor) Determines the color of the window bord- er. --ccrr _c_o_l_o_r (.cursorColor) Determines the color of the cursor. The default is the foreground color. --tthhoorroouugghh (.thorough) _X_d_v_i will usually try to ensure that over- strike characters (_e._g. \notin) are printed correctly. On monochrome displays, this is always possible with one logical operation, either _a_n_d or _o_r. On color displays, however, this may take two operations, one to set the appropriate bits and one to clear other bits. X Version 11 8 May 1989 2 XDVI UNKNOWN MANUAL SECTION XDVI If this is the case, then by default _x_d_v_i will instead use the _c_o_p_y operation, which does not handle over- striking correctly. The ``thorough'' option chooses the slower but more correct choice. See also -_c_o_p_y, below. --ccooppyy (.copy) Always use the _c_o_p_y operation when writing characters to the display. This option may be neces- sary for correct operation on a color display, but overstrike characters will be incorrect. --mmaarrggiinnss _i_n_c_h_e_s (.margins) Specifies the size of both the top margin and side margin. This can be a decimal number, _e._g., 1.5. It determines the ``home'' position of the page within the window as follows. If the entire page fits in the window, then the margin settings are ignored. If, even after removing the margins from the left, right, top, and bottom, the page still cannot fit in the window, then the page is put in the window such that the top and left margins are hidden, and presum- ably the upper left-hand corner of the text on the page will be in the upper left-hand corner of the window. Otherwise, the text is centered in the window. See also `MM' under the KEYSTROKES section. --ssiiddeemmaarrggiinn _i_n_c_h_e_s (.sideMargin) Specifies the side margin (see above). --ttooppmmaarrggiinn _i_n_c_h_e_s (.topMargin) Specifies the top and bottom margins (see above). --ppaappeerr _p_a_p_e_r_t_y_p_e (.paper) Specifies the size of the printed page. This may be of the form _wx_h (or _wx_hcm), where _w is the width in inches (or cm) and _h is the height in inches (or cm), respectively. There are also synonyms which may be used: us (8.5x11), usr (11x8.5), legal (8.5x14), foolscap (13.5x17), as well as the ISO sizes a1-a7, b1-b7, c1-c7, a1r-a7r (a1-a7 rotated), etc. The de- fault size is 8.5 x 11 inches. --mmggss[[nn]] _s_i_z_e (.magnifierSize[n]) Specifies the size of the window to be used for the ``magnifying glass'' for Button _n. See the MOUSE ACTIONS section. Defaults are 200, 350, 600, 900, and 1200. --mmggss _s_i_z_e Same as --mmggss11, above. X Version 11 8 May 1989 3 XDVI UNKNOWN MANUAL SECTION XDVI --ggeeoommeettrryy _g_e_o_m_e_t_r_y (*geometry) Specifies the initial geometry of the win- dow. ##_g_e_o_m_e_t_r_y (.iconGeometry) Specifies the initial position for the icon. --ddiissppllaayy _h_o_s_t:_d_i_s_p_l_a_y Specifies the host and screen to be used for displaying the dvi file. This is normally obtained from the en- vironment variable ``DISPLAY.'' KKEEYYSSTTRROOKKEESS XXddvvii recognizes the following keystrokes when typed in its window. Each may optionally be preceded by a (positive or negative) number, whose interpretation will depend on the particular keystroke. qq Quits the program. Control-C and control-D will do this, too. nn Moves to the next page (or to the nnth next page if a number is given). Synonyms are `ff', Space, Return, and Line Feed. pp Moves to the previous page (or back nn pages). Synonyms are `bb', control-H, and Delete. gg Moves to the page with the given number. Initially, the first page is assumed to be page number 1, but this can be changed with the `PP' keystroke, below. If no page number is given, then it goes to the last page. PP ``This is page number nn.'' This can be used to make the `gg' keystroke refer to actual page numbers instead of absolute page numbers. CCoonnttrrooll--LL Redisplays the current page. ^^ Move to the ``home'' position of the page. This is normally the upper left-hand corner of the page, depending on the margins as described in the -margins option, above. uu Moves up a window-full. dd Moves down a window-full. ll Moves left a window-full. X Version 11 8 May 1989 4 XDVI UNKNOWN MANUAL SECTION XDVI rr Moves right a window-full. cc Moves the page so that the point currently beneath the cursor is moved to the middle of the window. It also (gasp!) warps the cursor to the same place. MM Sets the margins so that the point currently under the cursor is the upper left-hand corner of the text in the page. ss Changes the shrink factor to the given number. If no number is given, the smallest factor that makes the en- tire page fit in the window will be used. (Margins are ignored in this computation.) SS Sets the density factor to be used when shrinking bit- maps. This should be a number between 0 and 100; higher numbers produce lighter characters. RR Forces the dvi file to be reread. This allows you to preview many versions of the same file while running _x_d_v_i only once. kk Normally when _x_d_v_i switches pages it moves to the home position as well. The `k' keystroke toggles a `keep- position' flag which, when set, will keep the same po- sition when moving between pages. Also `0k' and `1k' clear and set this flag, respectively. MMOOUUSSEE AACCTTIIOONNSS If the shrink factor is set to any number other than one, then clicking any mouse button will pop up a ``magnifying glass'' which shows the unshrunk image in the vicinity of the mouse click. This subwindow disappears when the mouse button is released. Different mouse buttons produce dif- ferent sized windows, as indicated by the --mmggss option, above. Moving the cursor while holding the button down will move the magnifying glass. Also, the scrollbars (if present) behave in the standard way: pushing Button 2 in a scrollbar moves the top or left edge of the scrollbar to that point and optionally drags it; pushing Button 1 moves the image up or right by an amount equal to the distance from the button press to the upper left-hand corner of the window; pushing Button 3 moves the image down or left by the same amount. EENNVVIIRROONNMMEENNTT Uses the environment variable ``DISPLAY'' to specify which bit map display terminal to use. The environment variable ``XDVIFONTS'' determines the X Version 11 8 May 1989 5 XDVI UNKNOWN MANUAL SECTION XDVI path(s) searched for fonts in the following manner. The string consists of one or more strings separated by colons. In each such string, the substring ``%f'' is changed to the font name; ``%d'' is changed to the magnification; and ``%p'' is changed to the font family (``gf'', ``pk'', or ``pxl''). If no ``%f'' appears in the string, then the string ``/%f.%d%p'' is added on the end. For example, if the string is ``/usr/local/tex/fonts'' and the font is cmr10 at 300dpi, then it searches for /usr/local/tex/fonts/cmr10.300gf, /usr/local/tex/fonts/cmr10.300pk, and /usr/local/tex/fonts/cmr10.1500pxl, in that order. If the first character of the ``XDVIFONTS'' variable is a colon, then the system default paths are tried first. If the font is not found in the desired size, then _x_d_v_i will try to find the nearest size. If the font cannot be found at all, then _x_d_v_i will try to vary the point size of the font (within a certain range), and if this fails, then it will use the font specified as the alternate font (cf. --aallttffoonntt). The ``XDVISIZES'' variable must be set to indicate which sizes of fonts are available. It should consists of a list of numbers separated by colons. If the list begins with a colon, the system default sizes are used, as well. Sizes are expressed in dots per inch; decimals may be used for ``pxl'' files: for example, a 300 dots per inch file magni- fied by half a step comes out to 1643 dots per five inches, which should be encoded as 328.6. The current default set of sizes is 300:328.6:360:432:518.4:622:746.4. FFIILLEESS /sprite/lib/fonts/pk Font pixel files. SSEEEE AALLSSOO X(1).
