GdkPixbuf animation
Hi all, I have noticed that there is a way to load an animation using gdk_pixbuf_animation_new_from_file. But is there a way to save already loaded/created animation to a file? For example GdkPixbuf has a method gdk_pixbuf_save Thanks in advance, Tomas Soltys ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

According to the docs it should be the first: gdk_pixbuf_version is an external variable which lives in the lib (so it should reflect the lib's version) while GDK_PIXBUF_VERSION is a C preprocessor macro which gets burnt into your code at compile time.

gdkpixbuf-animation: how to play without looping
Hi, I need to play a GdkPixbufAnimation without looping it. I.e. after the last frame is displayed, I do *not* want to display the first frame again... I don't know (at compile-time) which animation my program will need to play so I don't know its frame count and GdkPixbufAnimation won't let me know that. How can I do ?
