Hey there

I need to display an image on the screen which I need to be able to rotate, given any angle I want.
From the manual, I figured the only way to do this is to put the image as an object into the scene, then create a DynamicSprite from it, rotate it, and render it.

The problem I have is that when I use a DynamicSprite, the rendering is all messed up.



The middle image ("expected"), is what I get when I add the image to the scene as an object (the result I want).
The image on the right, is what I get when I use a DynamicSprite. As you can see, the edges don't look right. It seems a DS has a trouble dealing with alpha.

Here's my code:

Code: ags

    DynamicSprite* dsBigRocket;

    DrawingSurface* surface = Room.GetDrawingSurfaceForBackground();
        
    dsBigRocket = DynamicSprite.CreateFromExistingSprite(oBigRocket.Graphic, true);

    surface.DrawImage(
        1024 / 2 - dsBigRocket.Width / 2, 
        768 / 2 - dsBigRocket.Height / 2, 
        dsBigRocket.Graphic, 
        0);
        
    surface.Release();

I've also tried copying the transparency mask after creating the DynamicSprite but I get the same result.

What I my doing wrong?
Is there any other way to freely rotate an image and have it rendered correctly? I've been searching through the manual but couldn't find anything...


Thankies
