Title: Question: How to setup icon for SFML window
Post by: rpgmaker on March 17, 2009, 03:00:19 am

As the question stated, how do i do it. When ever i try to setup the icon, it always comes out wierd. Below is my code that i use

Code: [Select]


System.Drawing.Icon icon = new System.Drawing.Icon("Game.ico");
                MemoryStream ms = new MemoryStream();
                icon.Save(ms);
                byte[] data = ms.ToArray();
                Render.SetIcon((uint)icon.Width, (uint)icon.Height, data);
                icon.Dispose();
                ms.Close();

What output do you get? Do you have a screenshot?

Are you sure that Icon.Save only outputs pixels, and no header or metadata?

What about the last question:

I couldn't find accurate information about that in the MSDN. If you don't know, maybe you can just check if data.Length == Width * Height * 4.
Also make sure that the output format is 32 bits ARGB, and that the components are not swapped.

In other words, we have to know what icon.Save actually does :)

I will check that and get back. I tried the icon in sdl window and it works fine.

I checked it and the icon is 32 bits. Is there any other option to load the icon to the title bar?

This is a link to the icon file, if you want to check it out.

When i check the length of the btye array it is 6518. And the width * height * 4 is 4096. Basically meaning that it was not equal. The icon have Format32bppArgb according to C#, so it ARGB.

So it seems the output includes something else in addition to the array of pixels. I still couldn't find useful information about this, so maybe you should post on a .Net forum, as the problem is no longer related to SFML.

Sorry I couldn't help you more.
