im_init_world(3)
NAME
im_init_world, im_get_option_group - start up VIPS
SYNOPSIS
#include <vips/vips.h> int im_init_world( const char *argv0 ) GOptionGroup *im_get_option_group( void );
DESCRIPTION
- 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 - The argv0 argument is the value of argv[0] your program was passed by the host operating system. VIPS uses this with im_guess_prefix(3) to try to find the various VIPS data files.
EXAMPLE
- int
main( int argc, char **argv )
{ - if( im_init_world( argv[0] ) )
error_exit( "unable to start VIPS" );
- return( 0 );
- }
- im_get_option_group(3) returns a GOptionGroup containing various VIPS command-line options. It can be used with GOption to help parse argc/argv.
