| .SH SYNOPSIS |

| .SH DESCRIPTION |
| .B im_init_world(3) |
| starts up the VIPS library. It: |
| |
| - initialises any libraries that VIPS is using, including GObject |
| - starts up the threading system |
| - guesses where the VIPS data files are and sets up i18n |
| - loads any plugins from libdir/vips-x.x |
| |
| The |
| .B argv0 |
| argument is the value of |
| .B argv[0] |
| your program was passed by the host operating system. VIPS uses this with |
| .B im_guess_prefix(3) |
| to try to find the various VIPS data files. |
| |
| .SH EXAMPLE |
| |
| int |
| main( int argc, char **argv ) |
| { |
| if( im_init_world( argv[0] ) ) |
| error_exit( "unable to start VIPS" ); |
| |
| return( 0 ); |
| } |
| |
| .B im_get_option_group(3) |
| returns a |
| .B GOptionGroup |
| containing various VIPS command-line options. It can be used with GOption to |
| help parse argc/argv. |
