I have finally found a method that works in displaying the animated GIF file
with correct transparency:
using System;
using Gtk;
using Cairo;
public class MacMacro2 : Gtk.Window
{
public MacMacro2 (string imgstring) : base(Gtk.WindowType.Popup)
{
//base.AppPaintable = true;
Gtk.EventBox eb = new Gtk.EventBox();
eb.Colormap = Gdk.Screen.Default.RgbaColormap;
eb.Events = Gdk.EventMask.ButtonPressMask;
Gtk.Image img = new Gtk.Image(imgstring);
if(img.StorageType == Gtk.ImageType.Pixbuf){
Gdk.Pixbuf pba = img.Pixbuf;
img.Destroy();
base.Resize(pba.Width, pba.Height);
base.Move(Gdk.Screen.Default.Width - pba.Width,
Gdk.Screen.Default.Height
- pba.Height);
base.ExposeEvent += delegate(object o, ExposeEventArgs args) {
Context context =
Gdk.CairoHelper.Create(base.GdkWindow);
context.SetSourceRGBA(1.0, 1.0, 1.0, 0.0);
context.Operator = Operator.Source;
context.Paint();
Gdk.CairoHelper.SetSourcePixbuf(context,
pba.AddAlpha(true, 213, 218,
240), 0, 0);
context.Paint();
((IDisposable)context).Dispose();
};
}else if (img.StorageType == Gtk.ImageType.Animation){
img.Destroy();
Gdk.PixbufAnimation pba = new
Gdk.PixbufAnimation(imgstring);
Gdk.PixbufAnimationIter iter = pba.GetIter(IntPtr.Zero);
base.Resize(iter.Pixbuf.Width, iter.Pixbuf.Height);
base.Move(Gdk.Screen.Default.Width - iter.Pixbuf.Width,
Gdk.Screen.Default.Height - iter.Pixbuf.Height);
base.ExposeEvent+= delegate(object o, ExposeEventArgs
args) {
pba.Dispose();
Context context =
Gdk.CairoHelper.Create(base.GdkWindow);
context.SetSourceRGBA(1.0, 1.0, 1.0, 0.0);
context.Operator = Operator.Source;
context.Paint();
Gdk.Pixbuf temp = iter.Pixbuf;
Console.WriteLine(iter.DelayTime);
if(iter.DelayTime > -1)
{
Gdk.CairoHelper.SetSourcePixbuf(context, temp.AddAlpha(true, 213, 218,
240), 0, 0);
context.Paint();
//base.GdkWindow.InvalidateRegion(base.GdkWindow.VisibleRegion, true);
//base.GdkWindow.ProcessUpdates(true);
System.Threading.Thread.Sleep(iter.DelayTime);
iter.Advance(IntPtr.Zero);
//temp.Dispose();
((IDisposable)temp).Dispose();
((IDisposable)context).Dispose();
base.QueueDraw();
}else{
}
};
}else{
}
eb.ButtonPressEvent += delegate(object o, ButtonPressEventArgs
be) {
if(be.Event.Button == 3){
img.Destroy();
eb.Destroy();
base.Destroy();
Main.Quit();
}else{
img.Destroy();
eb.Destroy();
base.Destroy();
System.Diagnostics.Process.Start("website url
here");
Main.Quit();
}
};
//eb.Add(img);
//base.Add(eb);
//eb.Realize();
//eb.ShowAll();
}
}
But now I am having a very difficult time managing memory. However, the GIF
displays properly. The EventBox does not like being attached to this for
whatever reason.
