Hi guys: In a custom widget I use a pixbuf to update the image of the widget, I use:
internalPixbuf = new Pixbuf(buffer, Colorspace.Rgb, false, 8, ImageWidth, ImageHeight, ImageWidth * 3, null); //buffer of byte[] but the app crash with: ExcObject: System.InvalidProgramException: Invalid IL code in (wrapper native-to-managed) GdkSharp.PixbufDestroyNotifyWrapper:NativeCallback (intptr,intptr): IL_0030: call 0x00000006 at (wrapper managed-to-native) System.Object:__icall_wrapper_mono_delegate_to_ftnptr (object) at (wrapper managed-to-native) Gdk.Pixbuf:gdk_pixbuf_new_from_data (byte[],int,bool,int,int,int,int,GdkSharp.PixbufDestroyNotifyNative,intptr) at Gdk.Pixbuf..ctor (System.Byte[] data, Colorspace colorspace, Boolean has_alpha, Int32 bits_per_sample, Int32 width, Int32 height, Int32 rowstride, Gdk.PixbufDestroyNotify destroy_fn) [0x00000] I use GLib.ExceptionManager.UnhandledException to get that info :-S ... The weird thing is that with exactly the same code with mono-1.2.6 work like a charm and now the problem show up after a update to mono-1.9.1-3.1... Mike, from mono-devel mailing list tell me that this is a "know issue" (https://bugzilla.novell.com/show_bug.cgi?id=362951), from that thread I read about a "problem with the image" (in my case a total crash..) and also talk about some patch and some fix needed in mono about the "MarchalAs.." for the byte[] type and the GC, but I'm really confuse if this is something that can be fixed (update soources from svn+patch+compilation don't seems to be a "easy" option) with other approach? Also I try to use the PixbufLoader, but trying to build the pixbufloader with the (byte[], widht, height) constructor allways give me "Image with zero width" error..:-S, also try to use a MemoryStream to build the pixbufloader and the pixbuf with the same result.. there is some alternative?, is dificult to me to belive that this can't be handled in a diferent way, not posible to build the pixbuf beside a image from harddrive?, I use this custom widget with mono-1.2.6 (and the related version of gtk#) without any problem, and wait for a next RPM release for my fedora 8 is not a option for me...need to go back to mono-1.2.6? any ideas?, sugestions?, prays?. black magic?, budu? Thanks. Mauricio P.D: right now I'm using gtk-sharp2-100145-0.suse103.novell ..but same problem... _______________________________________________ Gtk-sharp-list maillist - [email protected] http://lists.ximian.com/mailman/listinfo/gtk-sharp-list
