A procedure uuuu will be defined that converts groff units to the coordinate system in effect.

A dictionary containing the definitions specified by the ddddeeeeffff and mmmmddddeeeeffff will be on top of the dictionary stack. If your code adds definitions to this dictionary, you should allocate space for them using \\\\XXXX''''ppppssss mmmmddddeeeeffff _n''''. Any definitions will persist only until the end of the page. If you use the \\\\YYYY escape sequence with an argument that names a macro, _c_o_d_e can extend over multiple lines.

There should be at most one definition per \\\\XXXX command. Long definitions can be split over several \\\\XXXX commands; all the _c_o_d_e arguments are simply joined together separated by newlines. The definitions are placed in a dictionary which is automatically pushed on the dictionary stack when an eeeexxxxeeeecccc command is executed. If you use the \\\\YYYY escape sequence with an argument that names a macro, _c_o_d_e can extend over multiple lines. \\\\XXXX''''ppppssss:::: mmmmddddeeeeffff _n _c_o_d_e'''' Like ddddeeeeffff, except that _c_o_d_e may contain up to _n definitions. ggggrrrrooooppppssss needs to know how many definitions _c_o_d_e contains so that it can create an appropriately sized PostScript dictionary to contain them. \\\\XXXX''''ppppssss:::: iiiimmmmppppoooorrrrtttt _f_i_l_e _l_l_x _l_l_y _u_r_x _u_r_y _w_i_d_t_h [ _h_e_i_g_h_t ]'''' Page 4 (printed 3/9/94) GGGGRRRROOOOPPPPSSSS((((1111)))) GGGGrrrrooooffffffff VVVVeeeerrrrssssiiiioooonnnn 1111....00009999 ((((22224444 FFFFeeeebbbbrrrruuuuaaaarrrryyyy 1111999999994444)))) GGGGRRRROOOOPPPPSSSS((((1111)))) Import a PostScript graphic from _f_i_l_e. The arguments _l_l_x, _l_l_y, _u_r_x, and _u_r_y give the bounding box of the graphic in the default PostScript coordinate system; they should all be integers; _l_l_x and _l_l_y are the x and y coordinates of the lower left corner of the graphic; _u_r_x and _u_r_y are the x and y coordinates of the upper right corner of the graphic; _w_i_d_t_h and _h_e_i_g_h_t are integers that give the desired width and height in groff units of the graphic. The graphic will be scaled so that it has this width and height and translated so that the lower left corner of the graphic is located at the position associated with \\\\XXXX command. If the height argument is omitted it will be scaled uniformly in the x and y directions so that it has the specified width. Note that the contents of the \\\\XXXX command are not interpreted by ttttrrrrooooffffffff; so vertical space for the graphic is not automatically added, and the _w_i_d_t_h and _h_e_i_g_h_t arguments are not allowed to have attached scaling indicators. If the PostScript file complies with the Adobe Document Structuring Conventions and contains a %%%%%%%%BBBBoooouuuunnnnddddiiiinnnnggggBBBBooooxxxx comment, then the bounding box can be automatically extracted from within groff by using the ssssyyyy request to run the ppppssssbbbbbbbb command. The ----mmmmppppssss macros (which are automatically loaded when ggggrrrrooooppppssss is run by the groff command) include a PPPPSSSSPPPPIIIICCCC macro which allows a picture to be easily imported. This has the format ....PPPPSSSSPPPPIIIICCCC _f_i_l_e [ ----LLLL | ----RRRR | ----IIII _n ] [ _w_i_d_t_h [ _h_e_i_g_h_t ]] _f_i_l_e is the name of the file containing the illustration; _w_i_d_t_h and _h_e_i_g_h_t give the desired width and height of the graphic. The _w_i_d_t_h and _h_e_i_g_h_t arguments may have scaling indicators attached; the default scaling indicator is iiii. This macro will scale the graphic uniformly in the x and y directions so that it is no more than _w_i_d_t_h wide and _h_e_i_g_h_t high. By default, the graphic will be horizontally centered. The ----LLLL and ----RRRR cause the graphic to be left-aligned and right-aligned respectively. The ----IIII option causes the graphic to be indented by _n. \\\\XXXX''''ppppssss:::: iiiinnnnvvvviiiissss'''' \\\\XXXX''''ppppssss:::: eeeennnnddddiiiinnnnvvvviiiissss'''' No output will be generated for text and drawing commands that are bracketed with these \\\\XXXX commands. These commands are intended for use when output from ttttrrrrooooffffffff will be previewed before being processed with ggggrrrrooooppppssss; if the previewer is unable to display certain characters or other constructs, then other substitute Page 5 (printed 3/9/94) GGGGRRRROOOOPPPPSSSS((((1111)))) GGGGrrrrooooffffffff VVVVeeeerrrrssssiiiioooonnnn 1111....00009999 ((((22224444 FFFFeeeebbbbrrrruuuuaaaarrrryyyy 1111999999994444)))) GGGGRRRROOOOPPPPSSSS((((1111)))) characters or constructs can be used for previewing by bracketing them with these \\\\XXXX commands. For example, ggggxxxxddddiiiittttvvvviiiieeeewwww is not able to display a proper \\\\((((eeeemmmm character because the standard X11 fonts do not provide it; this problem can be overcome by executing the following request ....cccchhhhaaaarrrr \\\\((((eeeemmmm \\\\XXXX''''ppppssss:::: iiiinnnnvvvviiiissss''''\\\\ \\\\ZZZZ''''\\\\vvvv''''----....22225555mmmm''''\\\\hhhh''''....00005555mmmm''''\\\\DDDD''''llll ....9999mmmm 0000''''\\\\hhhh''''....00005555mmmm''''''''\\\\ \\\\XXXX''''ppppssss:::: eeeennnnddddiiiinnnnvvvviiiissss''''\\\\((((eeeemmmm In this case, ggggxxxxddddiiiittttvvvviiiieeeewwww will be unable to display the \\\\((((eeeemmmm character and will draw the line, whereas ggggrrrrooooppppssss will print the \\\\((((eeeemmmm character and ignore the line. The input to ggggrrrrooooppppssss must be in the format output by ggggttttrrrrooooffffffff(1). This is described in ggggrrrrooooffffffff____oooouuuutttt(1). In addition the device and font description files for the device used must meet certain requirements. The device and font description files supplied for ppppssss device meet all these requirements. aaaaffffmmmmttttooooddddiiiitttt(1) can be used to create font files from AFM files. The resolution must be an integer multiple of 72 times the ssssiiiizzzzeeeessssccccaaaalllleeee. The ppppssss device uses a resolution of 72000 and a sizescale of 1000. The device description file should contain a command ppppaaaappppeeeerrrrlllleeeennnnggggtttthhhh _n which says that output should be generated which is suitable for printing on a page whose length is _n machine units. Each font description file must contain a command iiiinnnntttteeeerrrrnnnnaaaallllnnnnaaaammmmeeee _p_s_n_a_m_e which says that the PostScript name of the font is _p_s_n_a_m_e. It may also contain a command eeeennnnccccooooddddiiiinnnngggg _e_n_c__f_i_l_e which says that the PostScript font should be reencoded using the encoding described in _e_n_c__f_i_l_e; this file should consist of a sequence of lines of the form: _p_s_c_h_a_r _c_o_d_e where _p_s_c_h_a_r is the PostScript name of the character, and _c_o_d_e is its position in the encoding expressed as a decimal integer. The code for each character given in the font file must correspond to the code for the character in encoding file, or to the code in the default encoding for the font if Page 6 (printed 3/9/94) GGGGRRRROOOOPPPPSSSS((((1111)))) GGGGrrrrooooffffffff VVVVeeeerrrrssssiiiioooonnnn 1111....00009999 ((((22224444 FFFFeeeebbbbrrrruuuuaaaarrrryyyy 1111999999994444)))) GGGGRRRROOOOPPPPSSSS((((1111)))) the PostScript font is not to be reencoded. This code can be used with the \\\\NNNN escape sequence in ttttrrrrooooffffffff to select the character, even if the character does not have a groff name. Every character in the font file must exist in the PostScript font, and the widths given in the font file must match the widths used in the PostScript font. ggggrrrrooooppppssss will assume that a character with a groff name of ssssppppaaaacccceeee is blank (makes no marks on the page); it can make use of such a character to generate more efficient and compact PostScript output. ggggrrrrooooppppssss can automatically include the downloadable fonts necessary to print the document. Any downloadable fonts which should, when required, be included by ggggrrrrooooppppssss must be listed in the file ////uuuussssrrrr////llllooooccccaaaallll////lllliiiibbbb////ggggrrrrooooffffffff////ffffoooonnnntttt////ddddeeeevvvvppppssss////ddddoooowwwwnnnnllllooooaaaadddd; this should consist of lines of the form _f_o_n_t _f_i_l_e_n_a_m_e where _f_o_n_t is the PostScript name of the font, and _f_i_l_e_n_a_m_e is the name of the file containing the font; lines beginning with #### and blank lines are ignored; fields may be separated by tabs or spaces; _f_i_l_e_n_a_m_e will be searched for using the same mechanism that is used for groff font metric files. The ddddoooowwwwnnnnllllooooaaaadddd file itself will also be searched for using this mechanism. If the file containing a downloadable font or imported document conforms to the Adobe Document Structuring Conventions, then ggggrrrrooooppppssss will interpret any comments in the files sufficiently to ensure that its own output is conforming. It will also supply any needed font resources that are listed in the ddddoooowwwwnnnnllllooooaaaadddd file as well as any needed file resources. It is also able to handle inter-resource dependencies. For example, suppose that you have a downloadable font called Garamond, and also a downloadable font called Garamond-Outline which depends on Garamond (typically it would be defined to copy Garamond's font dictionary, and change the PaintType), then it is necessary for Garamond to be appear before Garamond-Outline in the PostScript document. ggggrrrrooooppppssss will handle this automatically provided that the downloadable font file for Garamond- Outline indicates its dependence on Garamond by means of the Document Structuring Conventions, for example by beginning with the following lines %%%%!!!!PPPPSSSS----AAAAddddoooobbbbeeee----3333....0000 RRRReeeessssoooouuuurrrrcccceeee----FFFFoooonnnntttt %%%%%%%%DDDDooooccccuuuummmmeeeennnnttttNNNNeeeeeeeeddddeeeeddddRRRReeeessssoooouuuurrrrcccceeeessss:::: ffffoooonnnntttt GGGGaaaarrrraaaammmmoooonnnndddd %%%%%%%%EEEEnnnnddddCCCCoooommmmmmmmeeeennnnttttssss %%%%%%%%IIIInnnncccclllluuuuddddeeeeRRRReeeessssoooouuuurrrrcccceeee:::: ffffoooonnnntttt GGGGaaaarrrraaaammmmoooonnnndddd In this case both Garamond and Garamond-Outline would need Page 7 (printed 3/9/94) GGGGRRRROOOOPPPPSSSS((((1111)))) GGGGrrrrooooffffffff VVVVeeeerrrrssssiiiioooonnnn 1111....00009999 ((((22224444 FFFFeeeebbbbrrrruuuuaaaarrrryyyy 1111999999994444)))) GGGGRRRROOOOPPPPSSSS((((1111)))) to be listed in the ddddoooowwwwnnnnllllooooaaaadddd file.
