Libgdx and mipmap texture filters

When I try to use mipmap filtering in LibGDX, none of the images appear.

I'm new to LibGDX, and I have a simple 2d scene with three rotating, scaled circles. To smooth them, I wanted to use linear filtering. For reference, I looked at this article , which said that for highly scaled images, mipmap can be used to increase speed and quality.

The first unexpected appearance was that although all my images were scaled down, I would only see a linear filter if magFilter was linear. In other words:

This code will show a linear filter for thumbnails:

parentTexture.setFilter(TextureFilter.Nearest, TextureFilter.Linear);

whlie this code will not:

parentTexture.setFilter(TextureFilter.Linear, TextureFilter.Nearest);

which seems to be the opposite of the libGDX function:

void com.badlogic.gdx.graphics.Texture.setFilter(TextureFilter minFilter, TextureFilter magFilter)

Try using the same minFilter and maxFilter. I had a similar problem and if I TextureFilter.Linear, TextureFilter.Linear or both MipMap the problem is resolved. Hope this helps.
