Is there some function like
pixbuf = gdk_pixbuf_new_from_buffer(buf)?
since pixbuf = gdk_pixbuf_new_from_file(file) has to handle a file on disk, what if my image data are stored in the memory already?
I do not want to write it into a file on disk then use pixbuf = gdk_pixbuf_new_from_file(file)
to get it back. ,that is too stupid .
