Dear Andrey,
Thanks alot for your guidance, but when i change the buffer data, image header
is also changed, and when using "gdk_pixbuf_loader_write", an error of
"unrecognized image file format" will be arised, this is because that the image
format is important for the loader.
is it any way to skip this restriction?
Thanks,
Zahra Zojaji

Subject: Re: How can I update the gdk-pixbuf raw data?
Hello, Zahra. You can use GdkPixbufLoader for retrieve pixbuf from raw
data. Code example: GdkPixbufLoader *loader = gdk_pixbuf_loader_new();
gdk_pixbuf_loader_write(loader, buffer, buffer_size, NULL);
gdk_pixbuf_loader_close(loader, NULL); GdkPixbuf* pixbuf =
gdk_pixbuf_copy(gdk_pixbuf_loader_get_pixbuf(loader)); g_object_unref(loader);
Now 'pixbuf' contains image, previously stored in 'buffer'. If you
want to do more complex things, than simple restoring pixbuf from buffer, you
may read GdkPixbufLoader description
