Hi,
I'm having trouble with Gdk.Pixbuf.Savev() method. Upon execution I get:
$ ./test.exe 001.JPG
001.JPG
=20
Unhandled Exception: System.NullReferenceException: A null value was
found where an object instance was required.
in (unmanaged) (wrapper managed-to-native) Gdk.Pixbuf:gdk_pixbuf_savev
(intptr,string,string,string,string,intptr&)
in <0x00004> (wrapper managed-to-native) Gdk.Pixbuf:gdk_pixbuf_savev
(intptr,string,string,string,string,intptr&)
in <0x0003a> Gdk.Pixbuf:Savev (string,string,string,string)
in <0x000a2> pixbufTest:Main (string[])
_____________________________________________
I attached this test.cs program, that attempts to load a picture from
file specified in the first command line argument and immediately save
it to another file using the Savev() method.
Is this a bug or did I get the parameters to the method wrong?
I'm using Gtk# Release 0.18
tnx,
Ivan
