[_p_p_m_f_i_l_e] DDEESSCCRRIIPPTTIIOONN ppppmmllaabbeell uses the text drawing facilities of ppppmmddrraaww to add text to a portable pixmap. The location, size, base- line angle, colour of the text and background colour (if any) are controlled by command line arguments. The text can be specified on the command line or read from files. Any number of separate text strings can be added by one invocation of ppppmmllaabbeell, limited only by the maximum length of the command line. If no _p_p_m_f_i_l_e is specified, ppppmmddrraaww reads its input pixmap from standard input. OOPPTTIIOONNSS The arguments on the ppppmmllaabbeell command line are not options in the strict sense; they are commands which control the placement and appearance of the text being added to the input pixmap. They are executed left to right, and any number of arguments may appear. All flags can be abbreviated to their shortest unique pre- fix. --aannggllee _a_n_g_l_e Sets the angle of the baseline of subsequent text. _a_n_g_l_e is specified as an integral number of degrees, measured counterclockwise from the row axis of the pixmap. --bbaacckkggrroouunndd ttrraannssppaarreenntt || _c_o_l_o_u_r If the argument is ````transparent'''',, text is drawn over the existing pixels in the pixmap. If a _c_o_l_o_u_r is given (see the --ccoolloouurr switch be- low for information on how to specify colours), rectangles enclosing subsequent text are filled with that colour. --ccoolloouurr _c_o_l_o_u_r Sets the colour for subsequent text. The _c_o_l_o_u_r can be specified in five ways: +o A name, assuming that a pointer to an X11-style colour names file was compiled in. 14 June 1995 1 ppmlabel(1) ppmlabel(1) +o An X11-style hexadecimal specifier: rgb:r/g/b, where r g and b are each 1- to 4-digit hexadecimal numbers. +o An X11-style decimal specifier: rg- bi:r/g/b, where r g and b are floating point numbers between 0 and 1. +o For backwards compatibility, an old- X11-style hexadecimal number: #rgb, #rrggbb, #rrrgggbbb, or #rrrrggggbbbb. +o For backwards compatibility, a triplet of numbers separated by commas: r,g,b, where r g and b are floating point numbers be- tween 0 and 1. (This style was added be- fore MIT came up with the similar rgbi style.) --ffiillee _f_i_l_e_n_a_m_e Reads text from the file _f_i_l_e_n_a_m_e and draws it on successive lines. --ssiizzee _t_e_x_t_s_i_z_e Sets the height of the tallest characters above the baseline to _t_e_x_t_s_i_z_e pixels. --tteexxtt _'_t_e_x_t _s_t_r_i_n_g_' Draws the given text string (which must be quot- ed if it contains spaces). The location for subsequent text is advanced by 1.75 times the current _t_e_x_t_s_i_z_e, which allows drawing multiple lines of text in a reasonable manner without specifying the position of each line. --xx _c_o_l_u_m_n Sets the column at which subsequent text will be left justified. Depending on the shape of the first character, the actual text may begin a few pixels to the right of this point. --yy _r_o_w Sets the row which will form the baseline of subsequent text. Characters with descenders, such as ``y'', will extend below this line. BBUUGGSS Text strings are restricted to 7 bit ASCII. The text font used by ppppmmddrraaww doesn't include definitions for 8 bit ISO 8859/1 characters. When drawing multiple lines of text with a non-transparent background, it should probably fill the space between the lines with the background colour. This is tricky to get right when the text is rotated to a non-orthogonal angle. 14 June 1995 2 ppmlabel(1) ppmlabel(1) SSEEEE AALLSSOO ppppmmmmaakkee(1), ppppmm(5) AAUUTTHHOORR Copyright (C) 1995 by John Walker (kelvin@fourmilab.ch) WWW home page: http://www.fourmilab.ch/ Permission to use, copy, modify, and distribute this soft- ware and its documentation for any purpose and without fee is hereby granted, without any conditions or restrictions.
