NAME
gtkimreg - GTK+ widget to select region of a (GdkImlib) image
SYNOPSIS
#include <gtk/gtkimreg.h> GtkType gtk_imreg_get_type (void); GtkWidget* gtk_imreg_new (const gchar * title, GdkImlibImage * im, int rw, int rh, GtkWidget * user_area); gint gtk_imreg_get_left (GtkImReg * imreg); gint gtk_imreg_get_top (GtkImReg * imreg); gint gtk_imreg_get_right (GtkImReg * imreg); gint gtk_imreg_get_bottom (GtkImReg * imreg); gint gtk_imreg_get (GtkImReg * imreg, gint * le, gint * to, gint * ri, gint * bo); gint gtk_imreg_set_left (GtkImReg * imreg, gint left); gint gtk_imreg_set_top (GtkImReg * imreg, gint top); gint gtk_imreg_set_right (GtkImReg * imreg, gint right); gint gtk_imreg_set_bottom (GtkImReg * imreg, gint bottom); gint gtk_imreg_set (GtkImReg * imreg, gint left, gint top, gint right, gint bottom);
DESCRIPTION
- Select an area in an image given as GdkImlib structure and obtain the
coordinates of this image. The user_area can be
- NULL or an user supplied widget to add certain functionality.
- The gtk_imreg_get_ functions are useful in an OK-callback to obtain the chosen coordinates. The gtk_imreg_set_ functions enable the user to preset a region selection.
EXAMPLE
See testimreg.c which is shipped with the sources. In a Debian system
you can find it under
/usr/share/doc/libgtkimreg-dev/example/testimreg
next to an appropriate Makefile and an image example.
REQUIRES
GTK+ 1.2, GdkImlib 1.9.2 or higher
