please someone has an idea on how i can to solve this problem??? here is my code.

main.adb

pragma Ada_2022;

with Gtk.Window; use Gtk.Window;
with Gtk.Main; use Gtk.Main;
with Gdk.Pixbuf; use Gdk.Pixbuf;
with Glib.Error; use Glib.Error;

procedure main is

Win : Gtk_Window; – the window
Pix, Pix2 : Gdk_Pixbuf; – declaration of two gdk-pixbuf (Pix and Pix2).
Erreur : Glib.Error.GError;

begin
Gtk.Main.Init;

Gtk_New (Win); – initialize the window
Win.Fullscreen;

Gdk_New_From_File (Pix, “Image.jpg”, Erreur);

Pix2 := Scale_Simple (Pix, 0, 0); – line 22.
– ^ error is raised here.

Gtk.Window.Set_Icon (Win, Pix2);

Win.Show_All;
Gtk.Main.Main;
end main;

when i run my code, it raise an exception :

I assume you’re using GtkAda? In which case, you’ll have to ask on the support forum for the language bindings you’re using.

I’m not sure it’s allowed to resize to width=height=0…
Does Scale_Simple (Pix, 1, 1) work?

Scale_Simple (Pix, 1, 1) no work. I already tried that.
