1/*! \page displaylib GRASS Display Library 2 3by GRASS Development Team (https://grass.osgeo.org) 4 5This library provides a wide assortment of higher level graphics 6commands which in turn use the graphics library primitives. It is 7highly recommended that this section be used to understand how some of 8the GRASS graphics commands operate. Such modules like 9<tt>d.vect</tt>, <tt>d.graph</tt>, and <tt>d.rast</tt> demonstrate how 10these routines work together. 11 12The routines fall into four basic sets: 13-# frame creation and management; 14-# coordinate conversion routines; 15-# specialized efficient raster display routines, and; 16-# assorted miscellaneous routines like pop-up menus and line clipping. 17 18Note: All routines and global variables in this library, documented or 19undocumented, start with <em>D_</em> prefix. To avoid name 20conflicts, programmers should not create variables or routines in 21their own modules which use this prefix. 22 23\section displayLibFns List of functions 24 25The library functions are defined in <tt>display.h</tt> header: 26 27\code 28#include <grass/display.h> 29\endcode 30 31- D_a_to_d_col() 32 33- D_a_to_d_row() 34 35- D_a_to_u_col() 36 37- D_a_to_u_row() 38 39- D_begin() 40 41- D_box_abs() 42 43- D_box_rel() 44 45- D_c_color() 46 47- D_cell_draw_begin() 48 49- D_cell_draw_end() 50 51- D_clip_to_map() 52 53- D_close() 54 55- D_close_driver() 56 57- D_color() 58 59- D_color_number_to_RGB() 60 61- D_color_of_type() 62 63- D_cont_abs() 64 65- D_cont_rel() 66 67- D_d_color() 68 69- D_do_conversions() 70 71- D_dots() 72 73- D_draw_cell() 74 75- D_draw_c_raster() 76 77- D_draw_d_raster() 78 79- D_draw_f_raster() 80 81- D_draw_raster() 82 83- D_draw_raster_RGB() 84 85- D_d_to_a_col() 86 87- D_d_to_a_row() 88 89- D_d_to_u_col() 90 91- D_d_to_u_row() 92 93- D_encoding() 94 95- D_end() 96 97- D_erase() 98 99- D__erase() 100 101- D_f_color() 102 103- D_fill() 104 105- D_fit_d_to_u() 106 107- D_fit_u_to_d() 108 109- D_font() 110 111- D_font_info() 112 113- D_font_list() 114 115- D_get_a() 116 117- D_get_a_east() 118 119- D_get_a_north() 120 121- D_get_a_south() 122 123- D_get_a_to_d_xconv() 124 125- D_get_a_to_d_yconv() 126 127- D_get_a_to_u_xconv() 128 129- D_get_a_to_u_yconv() 130 131- D_get_a_west() 132 133- D_get_d() 134 135- D_get_d_east() 136 137- D_get_d_north() 138 139- D_get_d_south() 140 141- D_get_dst() 142 143- D_get_d_to_a_xconv() 144 145- D_get_d_to_a_yconv() 146 147- D_get_d_to_u_xconv() 148 149- D_get_d_to_u_yconv() 150 151- D_get_d_west() 152 153- D_get_ew_resolution() 154 155- D_get_grid() 156 157- D_get_ns_resolution() 158 159- D_get_src() 160 161- D_get_text_box() 162 163- D_get_u() 164 165- D_get_u_east() 166 167- D_get_u_north() 168 169- D_get_u_south() 170 171- D_get_u_to_a_xconv() 172 173- D_get_u_to_a_yconv() 174 175- D_get_u_to_d_xconv() 176 177- D_get_u_to_d_yconv() 178 179- D_get_u_west() 180 181- D_get_window() 182 183- D_is_lat_lon() 184 185- D_line_abs() 186 187- D_line_rel() 188 189- D_line_width() 190 191- D_move_abs() 192 193- D_move_rel() 194 195- D_open_driver() 196 197- D_parse_color() 198 199- D_plot_icon() 200 201- D_polydots_abs() 202 203- D_polydots_rel() 204 205- D_polygon_abs() 206 207- D_polygon_rel() 208 209- D_polyline_abs() 210 211- D_polyline_rel() 212 213- D_pos_abs() 214 215- D_pos_rel() 216 217- D_RGB_color() 218 219- D_save_command() 220 221- D_set_clip() 222 223- D_set_clip_mode() 224 225- D_set_dst() 226 227- D_set_grid() 228 229- D_set_overlay_mode() 230 231- D_set_reduction() 232 233- D_set_region() 234 235- D_set_src() 236 237- D_setup() 238 239- D_setup2() 240 241- D_setup_unity() 242 243- D_show_conversions() 244 245- D_stroke() 246 247- D_symbol() 248 249- D_symbol2() 250 251- D_text() 252 253- D_text_rotation() 254 255- D_text_size() 256 257- D_translate_color() 258 259- D_update_conversions() 260 261- D_use_color() 262 263- D_u_to_a_col() 264 265- D_u_to_a_row() 266 267- D_u_to_d_col() 268 269- D_u_to_d_row() 270 271\section Authors Authors 272 273- Original author CERL 274- Major rewrite by Glynn Clements (2008) 275- Minor updates by Martin Landa <landa.martin gmail.com> (2011) 276 277*/ 278
