I found some code I used to create Pixbufs from RGB
System.Drawing.Bitmap objects:
public Gdk.Pixbuf CreateFromResource(Bitmap bitmap)
{
BitmapData data = bitmap.LockBits(new Rectangle(0, 0,
bitmap.Width, bitmap.Height,
PixelFormat.Format24bppRgb);
IntPtr scan = data.Scan0;
int size = bitmap.Width * bitmap.Height * 3;
byte[] bdata = new byte[size];
Gdk.Pixbuf pixbuf = null;
unsafe {
byte* p = (byte*)scan;
for(int i = 0; i < size; i++)
bdata[i] = p[i];
}
pixbuf = new Gdk.Pixbuf(bdata, false, 8,
bitmap.Width, bitmap.Height,
data.Stride, null);
bitmap.UnlockBits(data);
return pixbuf;
}
